This composition is about 1500 words in Grade Three. The topic is "Investigation Report on Residents' Understanding of Garbage Classification". Everyone is welcome to contribute enthusiastically. I. Proposition and purpose of investigation In today's society, people's pursuit of material life is getting higher and higher. With the continuous progress of society, the quality of people's living standards is constantly improving, and at the same time, domestic garbage is also increasing rapidly. So where should these rubbish be put? This problem has gradually become a problem for people. When people pursue material life, the demand for various resources is also increasing. Resources can be divided into renewable and non-renewable. Non-renewable resources are limited, but people's demand, the speed and quantity of renewable resources can't keep up with the speed and quantity of human use, and more and more accumulation leads to the exhaustion of resources. This has also become one of the problems that plague mankind. In this case, smart people will think, why not deal with the two problems together? We sort the garbage we produce and reproduce the resources we need. This not only solves the problem of garbage stacking, but also saves the use of resources. Isn't this a good way to kill two birds with one stone? However, the classification of this kind of garbage is not so smooth. People think that there is no special person in charge of garbage sorting? This idea is wrong. Responsibility and obligation of garbage sorting, we launched this survey. 2. Investigation time: April 5 ~ April 30, 2009. 3. Investigation locations: Shengli Park, Huayuan Community, Dongyue Community and Zhongshan Park. Four. Number of people surveyed: 60. V. Survey methods: field interviews, interviews and filming, and online collection of relevant information. Investigation process of intransitive verbs: 1. Form an investigation team and prepare the required tools and distribution tools. 2. Draw up investigative steps (time, place, object scope, etc. ). 3. Go to the place to be visited (park, community for shooting and interview). 4. Collate and summarize the data collected by the survey. Report the survey to teachers and classmates in class. 7. Investigation process: Make good preparations, and conduct investigation and interviews with people of all ages by means of field interviews, surveys and photos. The contents of the interview mainly include: what are your own understandings and opinions on garbage classification; Do you know the knowledge of garbage classification? What do you think of garbage sorting? 1. What is garbage classification? Each of us throws a lot of rubbish every day. They are usually sent to landfills first, and then to landfills. The cost of landfill is very high, and the cost of treating one ton of garbage is about 200 to 300 yuan RMB. People consume a lot of resources, produce a lot, consume a lot and produce a lot of waste. Do we separate and recycle resources at the source in the way of garbage disposal? 2. Benefits of garbage sorting (1) Recyclable garbage includes paper, metal, plastic, glass, etc. Through comprehensive treatment and recycling, pollution is reduced and resources are saved. If 1 ton waste paper is recycled, 850 kilograms of paper can be made, 300 kilograms of wood can be saved, and compared with the same output, pollution can be reduced by 74%. Every 1 ton plastic beverage bottle can get 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 wastes include food wastes such as leftovers, bones, roots and leaves. After in-situ composting by biotechnology, 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 ceramics, muck, toilet waste paper and other wastes that are difficult to recycle. Sanitary landfill can effectively reduce the pollution of groundwater, surface water, soil and air. 3. Investigation on people's understanding of garbage classification: (1) Ask the situation in person. Asking directions at the investigation site. Upon inquiry, 66% of them said they didn't know the garbage classification, 14% said there was no garbage classification at home, and most of the garbage was dumped in a mixed way. Recyclable garbage is generally sent to waste collection stations, and 20% people said they knew about it, but they never paid attention to it. Most of them think that this kind of garbage sorting is very troublesome, indicating that they are unwilling to divide it. (2) Questionnaire survey. Ask questions of passers-by and nearby residents. We came to the community and asked several passers-by and residents. Reporter: "Do you know there is garbage sorting?" Passerby: "I don't know. "Reporter:" How do you usually deal with the garbage at home? Passerby: Paper, metal and other waste products are sold in bundles at the purchasing station, while others are mixed together and dumped in the garbage bin. "Reporter:" Do you support garbage sorting? " Passerby: "Yes, but it's too much trouble. Let the cleaners share it. "Summarize and suggest that garbage is garbage only when it is mixed together, and once it is classified and recycled, it is treasure. Garbage classification creates a living environment for human beings, which is a society without garbage and recycling resources. If people do not pay attention to "saving energy, protecting the ecological environment and ensuring safety and health", domestic garbage will become the enemy of human beings, and human beings will be mercilessly punished by nature. I hope the relevant departments will do this work well. 1, set up publicity columns in communities and public places to strengthen publicity. 2. The theme of "saving energy, protecting ecological environment and ensuring safety and health" is widely reported by the propaganda media. 3. Every street has volunteers as persuaders to persuade those who don't pay attention to environmental awareness.
