When a situation or event needs to be understood, we need to investigate and show the results in the investigation report. What problems should be paid attention to when writing an investigation report? The following is a survey report on garbage classification carefully compiled by me. Welcome to share it.
Investigation report on garbage classification 1 With the rapid development of science and technology, the modernization process of cities is accelerated, and our lives have become colorful. However, along with these advances, it is not only the convenience of people's lives, but also the continuous deterioration of urban living environment. Environmental problem is one of the main social problems today, and the classified treatment of garbage is particularly important, which is directly related to the degree of environmental damage caused by domestic garbage. Therefore, sorting garbage well will be an important measure to alleviate environmental problems. In order to deal with domestic waste better and create a beautiful and comfortable living environment, several friends and I conducted some research on the domestic waste treatment in my city, and talked about my understanding and suggestions in combination with the reality.
First, the classification of garbage.
Garbage is mainly divided into: construction garbage, medical garbage, industrial garbage, sewage sludge and domestic garbage. Construction waste can be recycled by the construction unit; Medical waste is disposed of by hospitals and other health units; The treatment of industrial waste is mainly the responsibility of enterprises; Wastewater sludge is also treated by wastewater treatment plant. The production of these wastes is relatively concentrated, which is convenient for classified treatment.
Second, the benefits of garbage sorting
Classified garbage collection can reduce the amount and equipment of garbage treatment, reduce the treatment cost and reduce the consumption of land resources, which has social, economic and ecological benefits.
The advantages of garbage sorting treatment are as follows:
Reduce land occupation. Some substances in domestic garbage are not easy to degrade, which makes the land seriously eroded. Garbage classification can reduce the amount of garbage by more than 60% by removing recyclable and non-degradable substances.
Waste plastics in soil will lead to crop yield reduction; Waste plastic is eaten by animals by mistake, which will lead to animal death. Analysis Report on Market Prospect and Investment Planning of Domestic Waste Treatment Industry in China China uses 4 billion plastic fast food boxes and 500-700 million instant noodle bowls every year.
There are billions of disposable chopsticks, accounting for 8%~ 15% of domestic garbage. 1 ton of waste plastics can recover 600kg of diesel oil. Recycling 1500 tons of waste paper can avoid cutting down trees used to produce 1200 tons of paper. 1 ton cans can be melted to form 1 ton good aluminum blocks, and 20 tons of aluminum ore can be mined less. 30%~40% of production waste can be recycled, so we should cherish this small-scale and large-scale resource. You can also use cans as pencil boxes, which is environmentally friendly and saves resources.
Third, the characteristics of domestic waste
Compared with other garbage, the situation of domestic garbage is much more complicated, mainly in the following aspects:
1. The source is extensive and scattered, diverse and complex. The so-called domestic garbage, as the name implies, will produce domestic garbage as long as it is where people live. We live in different places, even in the same city, in the same corner of the city. It takes manpower and material resources to gather. Moreover, the life of modern people is complex and diverse, so there are all kinds of domestic garbage, such as plastic bags, paper towels, chewing gum, waste electronic products and so on. Involving inorganic, organic, degradable, difficult to degrade, toxic and harmful. In this way, it is no exaggeration to say that the sources of domestic waste are extensive, scattered and complicated.
2. People generally lack the common sense and habit of garbage sorting. The vague knowledge of garbage classification leads to people's poor understanding of the concept of garbage classification. For example, the classification of garbage at present is mainly divided into recyclable and non-recyclable. This classification is not clear enough. People only know some common recyclable garbage, but they don't know the unusual recyclable garbage. In my opinion, the classification of non-recyclable garbage is too general. Domestic garbage, such as plastic bags and melon seeds, can be said to be non-recyclable, but plastic bags are non-degradable, while melon seeds are degradable, and their treatment methods are different.
3. Some domestic wastes are improperly treated and lack of professional garbage disposal technology. This situation began to change from small and medium-sized cities. Due to the small scale of the city, there is no corresponding garbage disposal station. It is not uncommon for a large amount of domestic garbage to be piled up in the suburbs and burned on the spot. This leads to the re-pollution of domestic garbage, and the burning dust and toxic and harmful gases pollute the atmosphere, which directly affects the quality of life of residents.
4. Uneven hardware facilities in residential areas have brought great obstacles to the front end of garbage sorting. Some garbage bins in the community are classified garbage bins, and some are unclassified garbage bins. The front end that leads to garbage is not well handled, the garbage is not classified at all, and there is no way to deal with it in the later stage.
5. The intermediate treatment of domestic waste classification is unreasonable. The middle stage of garbage sorting treatment refers to the further classification of garbage in sanitation garbage transfer station, which will be a key step to determine the back-end treatment. The garbage transfer station further classifies the garbage, and then carries out different treatments on the classified garbage. If sanitation workers don't pay enough attention to garbage classification and mix the garbage that residents have classified, it would be a big mistake. The reason for this is that there are indeed many sanitation workers doing this.
6. The terminal treatment of domestic garbage is not scientific enough. At present, there are many methods to deal with domestic garbage, some of which are reasonable and some are unreasonable. For example, burning garbage in the open air is unscientific, which not only wastes the potential utilization value of garbage, but also pollutes the environment, which is really wrong. Similarly, the landfill method is not very reasonable. It is thankless to waste labor to landfill garbage. On the contrary, it is the best choice if domestic garbage is used for power generation or reused in different categories.
Fourthly, the method of classified treatment of domestic waste.
At present, domestic garbage in China can be generally divided into four categories: recyclable garbage, kitchen garbage, harmful waste and other garbage. At present, the commonly used garbage disposal methods mainly include comprehensive utilization, sanitary landfill, incineration for power generation, composting and resource reuse.
Recyclable garbage mainly includes waste paper, plastic, glass, metal and cloth. Waste paper mainly includes newspapers, periodicals, books, all kinds of wrapping paper, office paper, advertising paper, cartons, etc., but it should be noted that paper towels and toilet paper are too water-soluble to be recycled.
Plastics mainly include all kinds of plastic bags, plastic packaging materials, disposable plastic lunch boxes and tableware, toothbrushes, cups, mineral water bottles, toothpaste skins and so on.
Glass mainly includes all kinds of glass bottles, broken glass pieces, mirrors, light bulbs, thermos bottles and so on. Metal objects mainly include cans, cans and so on. Cloth mainly includes discarded clothes, tablecloths, towels, schoolbags, shoes, etc.
Kitchen waste includes food waste such as leftovers, bones, roots, leaves and peels. After in-situ composting by biotechnology, about 0.3 tons of organic fertilizer can be produced per ton.
Hazardous wastes include waste batteries, waste fluorescent tubes, waste water silver thermometers, expired drugs, etc., which need special treatment.
Other wastes include brick and tile ceramics, muck, toilet waste paper, paper towels and other wastes that are difficult to recycle except the above-mentioned types of garbage. Sanitary landfill can effectively reduce the pollution of groundwater, surface water, soil and air.
Verb (abbreviation for verb) Important measures in some cities
The key to realize waste reduction and recycling is front-end classification. If the government budget can take into account the "front-end" demand, provide special funds to encourage citizens to participate in waste sorting, subsidize volunteers who guide sorting and cleaning workers who engage in "secondary sorting", and increase investment in sanitation packaging and distribution equipment, then the implementation effect of waste sorting will be more obvious.
Garbage classification survey report 2 garbage problem is a long-standing problem. As long as people exist, garbage will accompany them. So, how can we live in peace with garbage? Faced with the encirclement of garbage, should we take effective measures to control it so as to use it to benefit mankind? At present, garbage sorting is an ideal method, which can effectively reduce the amount of garbage and increase the utilization value of garbage. Through investigation, we understand the current situation of garbage classification at home and abroad, understand the reasons that hinder garbage classification, put forward some feasible suggestions, and get some insights from it. Importance of garbage classification
(a) Knowledge of municipal solid waste
Municipal solid waste has become one of the world's urban problems. With the rapid growth of urban population in China, this problem is particularly serious and urgent. In fact, municipal solid waste is a resource and should not be a problem. Japan's garbage classification is extremely strict, attracting worldwide attention, and garbage has been effectively used. At home, we have just started in this respect, and we have already studied the classification of municipal waste. Pilot projects have been carried out in some big cities and many areas. We need more people to pay attention to this problem, so that most people can understand the garbage classification and take action. In this case, I made an investigation.
Domestic waste in China can be generally divided into four categories: recyclable waste, kitchen waste, harmful waste and other wastes. At present, the commonly used garbage disposal methods mainly include comprehensive utilization, sanitary landfill, incineration and composting.
1. Recyclable garbage mainly includes waste paper, plastic, glass, metal and cloth. Waste paper: mainly includes newspapers, periodicals, books, various wrapping papers, office paper, advertising paper, cartons and so on. However, it should be noted that paper towels and toilet paper are too water soluble to be recycled. Plastics: mainly include all kinds of plastic bags, plastic packaging materials, disposable plastic lunch boxes and tableware, toothbrushes, cups, mineral water bottles, etc. Glass: mainly includes all kinds of glass bottles, broken glass pieces, mirrors, light bulbs, thermos bottles and so on. Metal objects: mainly include cans, cans, toothpaste skins, etc. Cloth: mainly includes discarded clothes, tablecloths, towels, schoolbags, shoes, etc. Comprehensive treatment and recycling can reduce pollution and save resources. If every 1 ton of waste paper is recycled, 850 kilograms of paper can be made, 300 kilograms of wood can be saved, and pollution is reduced by 74% compared with the same output; Every 1 ton plastic beverage bottle can recover 0.7 tons of secondary raw materials; Every recovered 1 ton of scrap steel can produce 0.9 tons of steel, which saves 47% cost compared with ore smelting, reduces air pollution by 75%, and reduces water pollution and solid waste by 97%.
2. Kitchen waste, including food waste such as leftovers, bones, roots, leaves and peels, can be composted in situ by biotechnology, and 0.3 tons of organic fertilizer can be produced per ton.
3. Hazardous wastes include waste batteries, waste fluorescent tubes, waste water silver thermometers, expired drugs, etc. These wastes need special safety treatment.
4. Other wastes include bricks and tiles, muck, toilet waste paper, paper towels and other wastes that are difficult to recycle. Sanitary landfill can effectively reduce the pollution of groundwater, surface water, soil and air.
(2) The advantages of garbage sorting treatment are as follows:
1, reducing land occupation: some substances in domestic garbage are not easy to degrade, which makes the land seriously eroded. Garbage classification, removing recyclable and non-degradable substances, reducing the amount of garbage by more than 50%.
2. Reduce environmental pollution: Waste batteries contain toxic substances such as mercury and cadmium, which will cause serious harm to human beings. Waste plastics in soil will lead to crop yield reduction, and waste plastics will be eaten by animals by mistake, leading to animal death. So recycling can reduce the harm.
3. Turning waste into treasure: China uses 4 billion plastic snack boxes and 5.7 billion instant noodle bowls every year, and waste plastic accounts for 47% of domestic garbage. 1 ton of waste plastics can recover 600kg of diesel oil. Recycling 1500 tons of waste paper can avoid cutting down trees used to produce 1200 tons of paper. A ton of cans can be melted to form a ton of good aluminum blocks, and 20 tons of aluminum ore can be mined less. 30% and 40% of production waste can be recycled, so we should cherish this small-scale and large-scale resource. You can also use cans as pencil boxes, which is environmentally friendly and saves resources.
According to the data of the Municipal Solid Waste Treatment Committee of China Environmental Protection Industry Association, at present, 70% of municipal solid waste in China is treated by landfill, 20% by composting, 5% by incineration and 5% by other treatments (including open-air stacking and recycling).
But what is the current situation of garbage classification in Yancheng area? Most people throw garbage without sorting, mixing recyclable, non-recyclable and toxic. So, what is the reason for this situation? According to the survey, the reasons are as follows:
1. Our country lacks supervision and legal protection in this respect, and the relevant environmental protection departments have not paid enough attention to it. Although there are many classified trash cans on the street, they are just useless, and everyone has no awareness of sorting garbage. The government did not stand up and emphasize the need for garbage sorting, and the investment in garbage sorting was not enough, and the related garbage follow-up treatment facilities did not keep up.
2. People's awareness of garbage classification is weak and their knowledge of garbage classification is lacking. Some people think that it is the same whether garbage is classified or not, as long as it is not littered. Classification not only wastes time, but also wastes energy. These are all wrong understandings. It is understood that the garbage we throw out every day is generally sent to the garbage dump first and then to the landfill. The cost of landfill is high, and the cost of treating one ton of garbage is about between 200 yuan and 300 yuan. Nowadays, people consume a lot of resources, mass production and consumption, resulting in a lot of waste. How much land will this large amount of garbage turn into a landfill? Where will our children and grandchildren live? Therefore, landfill is a waste of resources. Garbage classification is to classify the garbage at the source and reclassify the garbage that can be used, which improves the utilization rate of resources, saves land and avoids the pollution caused by landfill fire burning.
(C) How to change the status quo
In this survey, the respondents ranged from primary school students to people over 60 years old, including civil servants, housewives and retirees. During the investigation, most citizens showed great concern and attention to the problem of domestic garbage, but they lacked understanding of the benefits of garbage recycling and were troubled by the classification of domestic garbage.
The survey also shows that ordinary people have realized that plastic bags and disposable fast food boxes in life have become a major problem in garbage disposal, but people who often use them still account for a large proportion. For knowing where the garbage is finally collected, most citizens can name several garbage disposal methods, and the public's awareness of garbage disposal needs to be strengthened. The crux: residents have not yet developed the habit of classification.
According to the relevant personnel of the Municipal Urban Management Bureau's Domestic Waste Landfill Management Center, community residents have not yet developed a good habit of garbage sorting. Although sorting collection boxes with different colors have been placed in some communities and roads, many people don't know which garbage can be recycled, and some residents mistakenly think that they have paid the sanitation fee. Garbage sorting should be a matter for the sanitation department. Besides, there are many people who litter.
It is understood that at present, the coastal communities of Dayang Street in Yancheng City have set up classified garbage bins of different colors and posted signs. However, garbage sorting has not become the conscious action of residents, and garbage bins have not been used alone for several years. Most of the daily garbage sorting is done by some sanitation workers and urban scavengers, who collect a small amount of recyclable garbage.
Expectation: early realization of domestic waste classification
According to experts, garbage classification is not a simple and fragmented problem, but a classification system, which consists of a series of links such as garbage classification collection, classification compression, classification transportation and classification utilization, and even some links overlap.
Facing people's poor awareness of garbage classification, our first task is to raise everyone's awareness. Therefore, we must increase publicity and guide everyone to implement garbage sorting. We can expand our influence by holding lectures, exhibitions, exchange meetings and other forms of activities, so that people can obtain relevant information through television, internet, newspapers, magazines and books. For example, we can write a practical manual on garbage classification, tell residents the treatment methods and classification principles of various domestic garbage in an easy-to-understand way, and let garbage classification penetrate into every resident's life.
At present, garbage sorting is not popular, so we should set up sorting boxes in qualified communities, carry out pilot work, arrange relevant personnel to give appropriate tips and guidance, and help residents gradually develop the habit of consciously sorting garbage. On the basis of certain achievements in the pilot work, it will be promoted in the whole region in accordance with the principle of "step by step, highlighting practical results" and continuously expand the scope of use of classified garbage bins. In order to stimulate residents' enthusiasm for garbage sorting, the environmental protection department of the government should provide convenience for residents as much as possible. For example, special equipment with clear identification will be provided, toxic harmful waste will be recycled at home regularly, and classified garbage bags will be given to residents.
(4) Summary
From the perspective of resource utilization and environmental protection, it is of great significance to properly handle domestic garbage. It takes a long time for community residents to develop the good habit of sorting out domestic garbage. After this investigation, I learned a lot about garbage classification. At the same time, I also experienced a day that I didn't feel at school. Maybe not everyone has a strong sense of environmental protection. Maybe every time I ask a question, I will be rejected by someone who is in a hurry. But in the hot summer, my enthusiasm is still burning. I think this is enough, because we have worked hard in this process and passed on our awareness of environmental protection.
Investigation report on garbage classification. The proposition of the problem:
With the development of social economy, environmental pollution is becoming more and more serious, and urban garbage can be seen everywhere. According to relevant data, in the past 10 years, the urban garbage in China increased at an average annual rate. Two thirds of the 400 large and medium-sized cities in China are surrounded by garbage. China has accumulated 6 billion tons of garbage over the years, occupying about 500 million square meters of land. At present, China is still producing hundreds of millions of tons of new garbage every year. How are these rubbish produced and how are they treated? These problems aroused our great research interest.
First, the current situation investigation:
In the morning, garbage can be seen everywhere on both sides of the street. Some are wrapped in plastic bags, some are thrown on the ground at will, and some are put in trash cans.
Passing by the hospital, I saw some expired drugs, discarded mercury thermometers, some medicine bottles and infusion sets abandoned in the corner of the hospital. These rubbish give off a pungent smell, which makes me afraid to go near.
In the corner of the factory building, abandoned batteries, old machines, circuit boards, broken glass and broken wood boards piled up into mountains. The battery was damaged and the liquid in it leaked out. Waste batteries are called "mini killers". We can imagine how much harm these waste batteries will do to the land after they penetrate into the soil.
In the vegetable market, discarded fish and vegetables are piled up on the road at will, and flies are buzzing. This surprised me. Are all the foods you can't buy thrown away at will?
A sanitation worker told me that these mountains of garbage were sent to a certain place for landfill or incineration.
Second, the harm of garbage:
Disposing of garbage at will is potentially harmful. How much land does it take to turn such a large amount of garbage into a landfill? How many toxic gases will be produced during incineration, which will endanger people's health? We constantly turn the limited earth resources into garbage, bury or burn them. Where will our future generations find the energy they need in a long time?
Third, the garbage classification treatment:
Are we helpless about the pollution of garbage? No, according to our investigation, garbage can be generally divided into four categories: recyclable garbage, kitchen waste, harmful waste and other garbage.
Recyclable garbage is directly sent to relevant factories for reprocessing and waste utilization. For example: 1 ton waste paper can be recycled into 800 kilograms of good paper; Rare metals such as zinc, copper and manganese dioxide can be extracted from recycled batteries; The recycled waste plastics can be recycled into fuel.
Kitchen waste, such as leftovers, lettuce, eggshell skin, cabbage leaves, etc. , can be piled up, let waste fiber and organic matter decay, into fertilizer, improve the soil.
In harmful waste, such as waste fluorescent tubes, expired drugs, etc., can be burned together, so as to minimize the harm of garbage.
Other garbage, such as ceramics and dregs, is difficult to recycle and has no harm to the environment. It can be effectively landfilled and reduce the pollution to groundwater, soil and air.
Fourth, our thinking:
Relevant statistics show that the value of waste that can be used but not used in China reaches 25 billion yuan every year, and about 3 million tons of scrap steel and 6 million tons of waste paper are not recycled. The recovery rate of waste plastics is less than 3%, and the recovery rate of rubber is 3 1%. Only more than 6 billion waste dry batteries contain more than 70,000 tons of zinc and 654.38+10,000 tons of manganese dioxide every year. Garbage sorting and recycling is of great value;
Waste paper:
Recycling waste paper 1 ton can regenerate 800 kilograms of good paper, save 0/7 trees/kloc-0, save 3 cubic meters of landfill space, save 240 kilograms of soda ash, reduce papermaking pollution emissions by 75%, and save papermaking energy consumption. Each paper can be recycled at least twice.
Waste plastics:
Plastics come from oil, which is a non-renewable resource on the earth. Recycling waste plastics is to save oil. All waste plastics, waste lunch boxes, food bags, woven bags, soft packaging boxes, etc. It can be recycled into fuel by reducing waste plastics into gasoline and diesel oil; 1 ton of waste plastics can produce 10 liter of unleaded gasoline or diesel oil.
Waste glass:
Recycling waste glass can not only save natural resources, but also reduce energy consumption by about 32%, air pollution by 20% and water pollution by 50%. Recycling 1 ton of waste glass saves 20% of the cost compared with using new raw materials. The benefits of recycling one ton of waste glass to the environment and resources are: 720kg of quartz sand, 250kg of soda ash, 60kg of feldspar powder, 0/0t of coal/kloc and 400 kwh of electricity can be saved.
Discarded aluminum cans:
After the waste cans are dissolved, they can be recycled 100% for countless times to make new cans, and can also be made into parts of cars, planes and even furniture. Recycling aluminum cans can save 95% of the energy needed for new aluminum cans and reduce 95% of air pollution. Discarding an aluminum can is equivalent to wasting half of the oil in the aluminum can.
Organic matter:
More than 40% of the garbage we still leave home every day is kitchen waste such as peels, eggshells, vegetable leaves and leftovers, which can be treated as organic fertilizer or feed by composting and fermentation.
Waste battery:
Mercury and cadmium contained in waste batteries are toxic heavy metals with high pollution, but rare metals such as zinc, copper and manganese dioxide can be extracted from recycled batteries.
Verb (abbreviation for verb) Our suggestion:
1, let people understand the importance of garbage classification through publicity;
2. Set up sorting bins in residential areas, vegetable markets, hospitals, factories and other places to facilitate sanitation workers to sort all kinds of garbage.
Garbage is a public hazard, but as long as we use the method of garbage classification to deal with it, we can completely turn garbage from enemies into friends.
2. Investigation report on ceramics
Today, we went to Zhejiang Museum to do a survey on ceramics. We are divided into two groups, A and B. Group A investigates pottery in the exhibition hall on the first floor and Group B investigates porcelain on the second floor. I joined group a.
After reading the introduction and listening to the explanation, I know that pottery and porcelain are not the same thing. Pottery appeared before porcelain. Pottery is a container made of small particles of soil. In ancient times, pottery was mainly used for sacrifice and burial.
Porcelain appeared in the Eastern Han Dynasty, and the surface of pottery was coated with a smooth glaze. According to the different glaze colors, there are many kinds of porcelain, such as celadon and white porcelain ... The famous celadon, because of the iron in the glaze, appears jasper-like cyan.
In ancient times, pottery and porcelain were used for sacrifice, inheritance and other activities. In modern times, ceramics have become daily necessities, which can help people to wash rice and serve rice, and become an indispensable item in family life.
Ceramics are indispensable in ancient and modern times, and they are the crystallization of the wisdom of the ancient working people in China.
Investigation report on garbage classification 4 With the improvement of our life and the progress of society, a large amount of garbage we produce has new treatment methods. Garbage in the kitchen, such as vegetable leaves, stones, leftovers, etc., can be treated as fertilizer or burned with biogas; We use broken TV, refrigerator, car and other metal-containing garbage, which can be reused after special treatment to save resources and protect the environment; The plastic waste we produce can also be treated into new plastic products. This is garbage classification, a common term in foreign countries, but it is not easy to implement in China. In foreign countries, garbage is divided into kitchen waste and harmful waste. In China, all I see are recyclable and non-recyclable, both of which are garbage sorting. Why is there such a big gap between different countries? What's the problem?
We looked around different communities and found that many communities did not classify garbage, so we began to conduct spot checks and interviews with residents in the communities. After asking a few simple questions, such as: Is the garbage classified? What do you think of garbage sorting? Do you know the function of garbage sorting? After some inquiries and investigations, we found that almost all people don't classify garbage, because it is very troublesome. Even if they want to classify, there is no place in the community to classify it. Most residents think that garbage sorting can't play a big role, and there are only a few garbage that can be recycled. They think that garbage sorting is not only troublesome, but also meaningless and not very supportive. Through the analysis and research of the survey results, we found that the implementation of garbage classification is not so simple.
In order to better classify garbage, I have the following suggestions: First, give relevant guidance, let people establish the concept of garbage classification, let people know the classification of each kind of garbage, and let people clearly understand the role and significance of garbage classification. Second, the relevant environmental protection departments should set up relatively perfect garbage sorting facilities to give residents a place to sort garbage. Thirdly, we should improve the method of garbage disposal. After garbage classification, different garbage has different treatment methods. We should not simply burn or bury it quickly, but should find the economic benefits of garbage. Fourth, carry out short-term household collection, classify the collected garbage and recycle it regularly. Fifth, expand the scope of garbage classification, not limited to a certain place. Sixth, formulate relevant regulations on garbage classification and severely crack down on the phenomenon of serious environmental damage caused by random disposal of garbage.
Garbage sorting can reduce environmental pollution, turn waste into treasure, save energy and lighten the work of sanitation workers, which plays an important role in our future healthy development.
