I. Problems
Since the second industrial revolution, the application of electricity has been gradually integrated into our lives. We have also been gradually inseparable from the existence of electricity. Since the introduction of the battery, this small and delicate power supply has been doubly popular, however, we are aware of this small battery will be an ecological environment of the killer it. Perhaps you have thoughtlessly thrown it into the pull box or even the roadside, perhaps you do not realize the harm it does, then, please enter our research project, you will have some understanding of it.
The purpose and content of the research
With the development of social economy, all kinds of batteries are also covered with our lives, but the harm of waste batteries has not attracted attention. Therefore, our group chose the topic of "the hazards of waste batteries and treatment methods", hoping that through our investigation and research, we can have a certain understanding of the hazards of waste batteries and treatment, but also hoping that through our investigation and research, we can wake up people's awareness, so that we notice the hazards of waste batteries.
Our hometown Shantou, is a beautiful city on the sea, we feel that we have the obligation to protect its beautiful environment, in the end, where the harm of waste batteries, the extent of which, our subject group to this end launched a series of investigation activities.
Three, the subject of the research process
1, the search for information and organize and analyze
After the subject is determined, our group members will divide the work, some on the Internet, some check the book, some check newspapers and magazines, around to collect information, which is an important part of our work. The information collected naturally helped us a lot. Afterwards, we also carried out a series of collation and analysis work, and put forward some of the problems arising from the investigation, I will not give detailed examples here. This information is also an important basis for us to summarize the paper.
2, field survey
(1) questionnaire
After the topic was determined, our team members made a questionnaire, distributed to our classmates, teachers, and part of the public, although the recovery rate of only 60% to 70%, and did not achieve the expected results, but we still seriously do a summary of the statistics, the data content still has a certain degree of The data content still has a certain degree of reliability.
(2) Interviews
In addition, we also interviewed the comrades of the Environmental Protection Bureau of the city on this issue, of course, the beginning is not very smooth, because of the conflict between school and work time, until the third time we met the person we want to interview, and after that, we are also very serious to the comrades of the Environmental Protection Bureau to ask for advice, and they also gave us a more comprehensive answer. (Afterwards we produced a transcript of the interview at that time, see appendix) This field interview can also be regarded as a certain result.
3, analysis and summary
After the completion of the data collection and investigation tasks, our team members divided the work, fought for two days and two nights, screening out useful information, the results of the survey on the serious analysis and discussion, and finally conceptualization and adjustment of the paper will be completed.
Four, the results of the study and analysis
Waste battery hazards and treatment
(A) waste battery generation and hazards
Dry cell batteries are one of the most widely used commodities in our daily life, from cameras, tape recorders, calculators and electronic alarm clocks to pagers, electronic dictionaries and handheld computers, can not be separated from the dry cell batteries. China is the production and consumption of dry batteries in large countries, a year of production of 15 billion, ranking first in the world, consumption of 7 billion, an average of each Chinese person a year to consume 5 dry batteries, so will produce a great number of waste batteries.
Waste batteries, although small, but the harm is great. However, due to waste battery pollution is not like garbage, air and water pollution can be felt by the senses, has a great degree of concealment, so has not been due attention. At present, China has become a big country in the production and consumption of batteries, waste battery pollution is a major environmental problem that needs to be solved urgently. In terms of volume and weight, waste batteries are insignificant in domestic waste, but it is very harmful, the battery contains mercury, cadmium, lead and other heavy metal substances. Mercury has strong toxicity, lead can cause nerve disorders, nephritis, etc.; cadmium mainly causes kidney damage and bone disease-osteoporosis, chondromalacia and fractures. If the waste battery mixed into the domestic waste together in the landfill, over time, the seepage of heavy metals may contaminate groundwater and soil.
For a long time, China has to add a toxic substance --- mercury or mercury compounds --- when producing dry batteries. China's alkaline dry batteries in the mercury content of 1 to 5%, neutral dry batteries for 0.025%, the country's annual production of dry batteries used in the production of tens of tons of mercury. Mercury is commonly known as "mercury". Mercury and mercury compounds are toxic, scientists have found that mercury has obvious neurotoxicity, in addition to the endocrine system, the immune system also has a negative impact on the endocrine system, etc. In the 1950s in Japan shocked the world's public disease - Minamata disease, is due to mercury pollution.
More than 40 years ago, in Minamata, a coastal town in southern Japan's Kyushu, a strange disease emerged among local residents. Patients began to slur their speech, have an unsteady gait, and paralyze their limbs, and eventually died in agonizing pain with spasms and insanity. Later on, more and more people contracted the disease, and even cats and seabirds showed the same symptoms. Later, medical workers found toxic methylmercury from the bodies of the dead and sea fish, proving that people were poisoned by eating contaminated fish. After investigation, it turned out that the local Japanese nitrogen fertilizer industrial company discharged mercury-containing wastewater into Minamata Bay all year round, which contaminated the seawater with mercury, and the locally caught seafood contained high concentrations of methylmercury.
In order to restore the ecological environment of Minamata Bay, the Japanese government spent 14 years and invested 48.5 billion yen to remove all of the mercury-containing substrate in Minamata Bay by digging 4 meters deep. At the same time, a quarantine net was set up at the entrance to Minamata Bay, and all contaminated fish in the bay were captured and landfilled. Yoshii Masazumi, the mayor of Minamata City, Japan, who witnessed the outbreak of Minamata disease, said with emotion: "After nearly half a century of unremitting efforts, we have finally emerged from the shadow of Minamata disease and are building a new Minamata City. I hope that the whole world will learn from the lessons of Minamata disease in Japan and get rid of foolish production methods and promote civilized production methods."
It can be seen that the harm of waste batteries to the environment and the human body is far more than we can imagine, and the casual disposal of batteries not only pollutes the environment and jeopardizes human health, but also wastes resources. To produce 10 billion batteries per year, the annual consumption of 156,000 tons of zinc, 226,000 tons of manganese dioxide, 2080 tons of copper, 27,000 tons of zinc chloride, 79,000 tons of ammonium chloride, 43,000 tons of carbon rods. Therefore, the recycling of waste batteries, beneficial to the country and the people, is imperative. This requires people to find ways to solve the pollution of waste batteries.
(B) the recovery of waste batteries
Waste batteries say waste is not actually "waste", which contains a large number of non-ferrous metals, and non-ferrous metals are non-renewable valuable resources on earth. The best way to deal with waste batteries is to regenerate and utilize them, extract the useful components, and turn waste into resources. Recycling of waste batteries is the first and most difficult part of environmental management of waste batteries. As the users of batteries throughout the thousands of households, units, individuals, and the amount of each user is not very large, resulting in the collection of waste batteries is very difficult. Waste battery environmental management is a complex systematic project, involving the collection, classification, transportation, treatment, disposal and a series of processes, involving a wide range of environmental protection departments, sanitation departments, economic management departments, battery manufacturers, battery sellers and the public *** with the cooperation in order to do a good job, and at the same time, publicity and education means to be combined with administrative, legal and economic means, a multipronged approach in order to Promote this work.
But, according to the China Battery Industry Association statistics, China's current waste battery recycling rate of less than 2%.
We take Shanghai as an example, which is a leader in waste battery recycling nationwide, there are five ways to recycle waste batteries in Shanghai: set up a special "hazardous waste" sorting box in pilot districts or a special waste battery recycling office; set up a waste battery recycling office in schools, universities, primary and secondary schools, as well as government agencies from 1998; more than 2,000 "Oriental kiosks" all over the city, where people can buy new batteries with a section of waste batteries, which can be used to recycle waste batteries. In more than 2,000 "Oriental Newspaper Kiosks" throughout the city, citizens can enjoy a 20-cent discount when buying new batteries by presenting a used battery; there are recycling points in large supermarkets such as Hualian and Lianhua, as well as in some large shopping malls; and special baskets for recycling used batteries are installed in the street's sorting garbage bins. Although Shanghai has started the recycling of waste batteries since May 1998, and the city's waste battery recycling points have reached more than 6,000, and more than 175 tons of waste batteries have been recycled so far, there is still a big distance to go compared with the 3,200 tons of waste batteries the city produces every year.
Currently, developed countries have made great progress in the environmental management of waste batteries. In Germany, the waste battery has now done all the collection, classification treatment and disposal. The government has legislated, clearly stipulated: for the toxicity of lead-acid batteries, mercury-containing batteries, cadmium-nickel batteries, etc. must be marked with recycling logo; battery manufacturers and distributors must collect all waste batteries; distributors must be marked and unmarked batteries to be categorized; battery manufacturers must be set up to regenerate battery recycling and treatment facilities; for all waste batteries must be given priority to the regeneration of recycling for the non-recyclable batteries to be based on waste management and disposal. Non-renewable batteries should be properly disposed of in accordance with the waste management law; in the production of batteries, to further reduce the heavy metal content of batteries, especially to reduce the mercury content of alkaline manganese batteries, and actively develop new products that are less harmful to the environment.
The United States is one of the countries with the most detailed legislation on environmental management of waste batteries, which has not only established a comprehensive waste battery recycling system, but also set up a number of waste battery treatment plants, and at the same time, persistently publicize and educate the public, so that the public consciously support and cooperate with the recycling work of waste batteries.
(C) Treatment of waste batteries
The recovery of waste batteries is the first step of recycling, and reprocessing is the key to recycling. At present, the waste batteries that have been recovered are still lying in the warehouse, homeless.
The technology to deal with waste batteries is not a problem, developed countries already have ready-made technology, take over and use it. It is understood that the suburbs of Magdeburg, Germany, is building a "wet processing" device, where, in addition to lead batteries, all types of batteries are dissolved in sulfuric acid, and then with the help of ionic resins from the solution to extract a variety of metals, raw materials obtained in this way than the heat treatment method of purity, and therefore sold at a higher price in the market, and batteries contain a variety of substances are extracted out of 95%. Wet treatment eliminates the need for sorting (which is a manual process that increases costs). With a capacity of up to 7,500 tons per year, the Magdeburg plant is slightly more expensive than landfills, but valuable raw materials are not thrown away and do not pollute the environment. This unit has a processing capacity of 7,500 tons per year.
Germany Alter developed the vacuum heat treatment method is also cheap, but this first need to sort out the waste batteries in the nickel-cadmium batteries, waste batteries heated in a vacuum, in which the mercury quickly evaporated, can be recycled, and then the remaining raw materials grinding, with magnets to extract metallic iron, and then from the remaining powder to extract nickel and manganese. This processing of one ton of waste batteries costs less than 1,500 marks.
Switzerland: there are two factories specializing in the processing and utilization of old batteries, Barticle company takes the method of grinding the old batteries, and then sent to the furnace to heat, which can be extracted volatile mercury, higher temperature zinc also evaporate, it is also a precious metal. Iron and manganese are fused together to make a manganese-iron alloy for steelmaking. The plant can process 2,000 tons of waste batteries a year, obtaining 780 tons of ferromanganese alloy, 400 tons of zinc alloy and 3 tons of mercury. Another plant extracts iron directly from the batteries and sells a mixture of metals such as manganese oxide, zinc oxide, copper oxide and nickel oxide directly as metal scrap. The thermal treatment method is more expensive, however, and Switzerland also mandates a small fee per battery buyer dedicated to the processing of used batteries.
As far as we know, some domestic research units and enterprises have also developed related technologies. Adopting the waste battery processing technology of the University of Science and Technology Beijing, the Hebei Province Donghua Xinxin Waste Battery Regeneration and Treatment Plant is under construction. Beijing Municipal Development and Planning Commission has also approved the use of European technology and equipment, the establishment of waste dry battery treatment plant. Xinxiang Battery Factory in Henan Province has already had scientific and technical personnel design a complete set of technology and production equipment for the recycling and reutilization of waste batteries. After two years of research, Anshan City, Liaoning Province, a successful trial of waste battery recycling resource regeneration and harmless treatment process, has passed the relevant experts and relevant departments to demonstrate.
(D) China's current waste battery recycling and treatment of the status quo
In order to strengthen the prevention and control of mercury pollution of battery products, to protect and improve China's ecological environment, the former China Light Industry Council and other 9 departments on December 31, 1997 had jointly issued a "mercury content on the limitation of battery products," the requirements of the January 1, 2001 onwards, imported batteries will be by the national entry-exit inspection and quarantine departments to implement mandatory inspection. Inspection and quarantine departments to implement mandatory inspection. According to the "provisions" requirements, China's battery industry will be phased to achieve the restriction of mercury content of battery products, first of all, to achieve low mercury, and ultimately to achieve mercury-free. Low-mercury means that the mercury content in the battery is less than 0.025% of the weight of the battery; mercury-free means that the mercury content in the battery is less than 0.001% of the weight of the battery.
The Provisions clearly put forward, since January 1, 2001, prohibit the domestic production of all types of batteries with mercury content greater than 0.025% of the weight of the battery. From January 1, 2001 onwards, where the domestic market into the sale of domestic and foreign battery products (including batteries with electrical appliances), in the single battery to be marked on the mercury content (such as: indicate "low mercury" or "mercury-free"), the mercury content of the batteries are not marked are not permitted to enter the market for sale. Since January 1, 2002, it is prohibited to sell batteries with mercury content greater than 0.025% of the weight of the battery in the domestic market. Since January 1, 2005, the domestic production of alkaline zinc-manganese batteries with mercury content greater than 0.001% by weight of the battery has been prohibited. Since January 1, 2006, prohibit the domestic distribution of alkaline zinc-manganese batteries with mercury content greater than 0.001% by weight of the battery. In order to ensure that the inspection of imported batteries on schedule, the State Entry-Exit Inspection and Quarantine Department is making good preparations for the opening of the inspection.
With the improvement of people's awareness of environmental protection, the hazards of waste batteries has also attracted the attention of all sectors of society, more and more people began to consciously collect waste batteries: In August 2000, the Beijing Youth Daily reported that Tian Guirong in Xinxiang, Henan Province, personally spent more than 20,000 yuan to collect waste batteries amounted to 30 tons. 2002, April "Yangtse Evening News," reported that the city of Xuzhou, 68-year-old retired teacher Ding Fengzhu, used three years to collect thousands of batteries. Three years to collect thousands of large and small used batteries.
At the same time, environmental protection organizations across the country have also carried out waste battery recycling activities, calling on people to collect used batteries to reduce environmental pollution. 100 institutions in Beijing in December 2001 joined hands to carry out "into the campus, to protect the home" recycling of waste batteries large-scale activities, mobilizing students to actively participate in the organization of the collection of waste batteries in the action, and has received a very good effect. Government agencies also played a role in this campaign. Government agencies also played a role in this campaign, in 2000, the Beijing Municipal Bureau of Sanitation and McDonald's, Rogers, Polaris Pictures, Good Neighbors, Oshikai, Xinjiekou Department Store and other more than 50 fast-food restaurants, more than 40 chain stores to cooperate in the collection of waste batteries, and some of the shopping malls battery counters on the collection of bins, the Bureau of Sanitation dedicated to the sorting of garbage cans constitute a "search and arrest" of the small batteries of the large network.
However, in the boom of recycling waste batteries, we found that waste batteries are still not recycled. Although the recycling of waste batteries has been supported by the people, the reporter found that the battery recycling situation is not optimistic, the recovery of old batteries only accounted for the sale of a very small part of the battery. What is the problem? We believe that the reasons are:
1. Government departments in this work does not really play a role in the "fixed waste prevention and control law", did not develop detailed rules on battery recycling, recycling and non-recycling without incentives, penalties, the relevant departments can not produce enterprises, recycling departments, individuals to make targeted guidance.
2. At present, the recycling network of waste batteries is basically an organization, individual spontaneous "weave" from the publicity efforts, but due to the lack of awareness of the hazards of waste batteries by residents, there is no universal conscious collection, consciously turn in the consciousness, so waste batteries are still difficult to quot;big network". Although there are individuals engaged in the collection of work, but the limitations of personal capacity, the formation of the scale, after several years of hard work, the number of collection is only a "drop in the ocean" of the sales volume.
3. Battery manufacturers provide hundreds of millions of batteries to society every year, but only a handful of them are really aware of and involved in the recycling process.
This problem, we put forward three suggestions:
1. To increase publicity, so that more and more people to establish the concept of waste dry batteries must be recycled, and thus consciously participate in recycling activities.
2. The state should give some support in terms of policies and regulations, scientific and technological innovation and capital investment, the development of relevant policies and regulations, waste dry batteries must be recycled, waste dry batteries are prohibited from being thrown into the living garbage; actively involved in the recycling of waste dry batteries in scientific research units and enterprises should be given the policy and funding tilt to ensure that the value of investor capital appreciation and the treatment of the unit's products. Priority promotion.
3. For the recycling of waste dry batteries to create a variety of convenient conditions, such as in the public **** place to set up waste dry batteries recycling boxes, accelerate the popularization of waste classification and recycling, in the residential areas generally set up a special recycling of batteries in the garbage cans; in the sale of batteries, the implementation of the collateral system, or the use of trade-in system to ensure that the recycling rate of waste dry batteries. As long as the full mobilization of all the forces of society, the recovery of waste batteries is not difficult to solve.
(E) the city's current status of waste battery recycling treatment
Shantou City is currently in the country, waste battery recycling treatment is a medium level, and the establishment of recycling bins in the country is in the forefront, but due to the country has not yet had a waste battery recycling treatment of the center, so now can only be the backlog of waste batteries can not be dealt with. In order to call an in-depth understanding of Shantou people's recycling and disposal of waste batteries, we organized a survey and selected 200 questionnaires to be counted. The results found that:
1. Batteries are widely used, 70% of the respondents use batteries more, and most of them are disposable batteries
2. The awareness of recycling of waste batteries is weak. 8.5% of the respondents pile up waste batteries at home; 64.2% of the respondents don't know the situation of recycling of waste batteries in Shantou; 62.3% of the respondents don't know the relevant policies. Only 41.5% of the respondents know the number of waste battery recycling bins in Shantou.
3. The hazards of waste batteries are not known. Only 16.9% and 9.0% of the respondents know that waste batteries pollute water and air, and 22.3% know that they jeopardize human health.
4. Waste battery recycling and treatment confidence is greater, 49.1% of the respondents believe that waste battery recycling and treatment is very promising.
Through this study on waste battery recycling, we have improved a lot of knowledge at the same time, but also realize that most people's awareness of environmental protection needs to be strengthened, and we hope that waste batteries will have a bright future in the near future under the efforts of everyone.

Appendix II Interviews
1.Q. What is the status of recycling waste batteries nationwide?
A; Well, the national environmental protection system attaches great importance to this, but waste batteries are difficult to recycle, the technical requirements are high, and the country has not issued the appropriate laws and regulations, so most of the waste batteries are backlogged. From the country, Shanghai, Shenzhen has more advanced recycling equipment, Shantou in the country is a medium level, in the establishment of recycling boxes and even in the country's first.
2. Q: What is the current consumption of batteries?
A; Guangdong Province, the annual output of 3 billion batteries, two-thirds of exports, local consumption of 1 billion, relatively speaking, or more.
3. Q: When did the campaign to recycle waste batteries in Shantou start?
Answer; In 2001, Zhongshan No.4 Elementary School and Golden Park cooperated to carry out the activity of advocating waste battery recycling, and achieved some results. At the end of 2001, 30 waste battery recycling bins were set up, which is the only channel for waste battery recycling in the city.
4. Q: waste batteries on the environment, the human body, how serious is the harm?
Answer; we all know that waste batteries contain acid and alkali electrolytes, and mercury, cadmium, lead and other heavy metals. Mercury is highly toxic, not easy to degrade, easy to volatilize into the atmosphere, pollute water, soil.
Harm to the human body: the "food chain" approach: soil decay - deep soil - groundwater - rivers and lakes - aquatic organisms - animals - people.
Particularly in cell phone batteries, cadmium is a carcinogen, and Japan has been caused by the "pain" caused by the disease.
5. Q: What are the current regulations?
Answer; the regulations, but also in the study, has identified two drafts, is estimated to be formally introduced next year.
6. Q: What is the treatment of waste batteries? The main part of the recovery?
Answer; at present it is not possible to carry out large-scale processing, most of the waste batteries are just stored. Guangdong Province, there is a recycling center, that is, "Guangdong Province in the Huan environmental protection technology promotion Shiwan waste battery light tube transit warehouse. Now is preparing to build a comprehensive waste treatment demonstration center, once completed, it will be able to waste batteries for large-scale treatment. The main recovery
Harmful substances in waste batteries.
7. Q: What are the current difficulties in recycling waste batteries?
Answer; the difficulties are mainly: the harmful substances in waste batteries in milligrams, the content is small, the recovery is difficult, cumbersome processing, high technical requirements, high cost. The masses have little awareness of this, poor enthusiasm. The distribution of recycling bins is narrow and the number is small.
8. Q: Why don't we implement the "compensation" system popular in foreign countries?
A; domestic technical limitations, difficult to deal with. Waste battery recycling and treatment system has not yet been established, although the treatment of waste batteries social benefits, but the economic benefits of small, low profits.
9. Q: How is the publicity of waste battery recycling?
Answer; we publicize through newspapers, radio, TV and other aspects. We set up an environmental protection column in Shantou Daily. Teacher's comment: This group chose this question for research in the light of the progress of modern society and the popularization of electrification in life, as well as the preliminary practice of the environmental protection department of our city on the recycling and treatment of waste batteries.
The whole group of students divided the work, design questionnaires, visit Shantou Environmental Protection Bureau relevant comrades interviews, access to relevant information, organize discussions and research, collate information, access to a large amount of data and claims. Through *** with the study, get *** knowledge: a small waste battery has a great harm, and not only waste batteries, a variety of chemical products, such as "white pollution" and so on are very serious pollution of the living environment, we must vigorously from the ideological awareness to improve the general public's awareness of environmental protection, in order to fundamentally reduce environmental pollution. It can be seen, through the research study, not only to cultivate the students to participate in social practice, social research, self-learning, inquiry, innovation, and cultivate the awareness of environmental protection, the future can become a knowledgeable modern talents.
