Soil heavy metal pollution concentrated multiple "cancer village"

Land pollution, especially heavy metal pollution, brings major hidden dangers to people's lives, that is, life safety is challenged, occupational diseases are high, the mortality rate has risen sharply, and the age of death is generally advanced to about 45 years old. At the same time, due to the lack of corresponding treatment mechanism, improper response may lead to public health incidents or mass incidents at any time. Zhang Jianxin, director of the basic scientific research department of Hunan Provincial Institute of land and resources planning, said that after investigating the health records of 70000 people for 25 years, they found that from 1965 to 2005



Solve the worries of battery development

With the rapid development of electric vehicles, batteries, as one of the key and core components of electric vehicles, have undoubtedly become the focus of attention of the majority of investment institutions and enterprises. Behind the vigorous development of power batteries, there are some people who are wholeheartedly operating an environmental protection business that serves the general public-battery recycling. Zhang Yongxiang, general manager of Shenzhen Taili Waste Battery Recycling Technology Co., Ltd., is one of them. Zhang Yongxiang, who is optimistic by nature, told reporters: "in fact, this industry is not lonely. There are so many battery manufacturers, electronic product manufacturers and consumers with us. How many electronic products and electric vehicles use batteries will produce how many used batteries, and even more. Electric vehicle manufacturers have solved the zero emission of vehicles, and we have solved the recycling and reuse of scrapped batteries of electric vehicles. This is the actual sense to achieve zero pollution and complete environmental protection." Recalling that he had just entered the battery recycling industry in 2007, Zhang Yongxiang was deeply touched: "At that time, battery recycling was still a blank, except that some second-hand mobile phone shops were recycling mobile phones and batteries, which they used to renovate and resell. Battery companies piled up scrapped batteries in warehouses, and the number of batteries stored in a few years was very large. People in residential areas throw all kinds of used batteries together with domestic garbage; the waste recycling station also removed the battery from the recycled electronic products. After accumulating a certain amount, it was confused and did not know where to digest." The emergence of Taili has solved many problems caused by waste batteries in battery companies. First, it has freed up a lot of warehouse space, and secondly, it has turned waste batteries into cash flow. The market is constantly expanding with the development of electric vehicles and non-plug-in electrical appliances. Promoting environmental protection is the primary task. What is fresh in Zhang Yongxiang's memory is that those environmental protection volunteers have already started to take action. They voluntarily recycle used batteries in the community and then send them to Taili Company in person. This moved Zhang Yongxiang very much: "Although these used batteries have no value at all, but what they do cannot be measured in monetary terms." Significant technical advantages Battery recycling is a thing that benefits the country and the people, but battery recycling also faces many "embarrassing" technical problems in battery recycling and post-processing, policy issues, and imperfect industry systems. Zhang Yongxiang has his own unique views and Suggestions, and as one of the pioneers in the industry, it also has huge advantages in technology and processing methods. Zhang Yongxiang said that in terms of battery recycling, there have indeed been many embarrassments. There are many waste recycling individuals who do not have the recycling qualification to recycle waste batteries without permission. Without a special storage place, it is easy for batteries to short-circuit and cause fires. There are also some battery companies that sell waste batteries to anyone who gives them a high price for profit, regardless of whether the other party has the qualification to recycle. As a result, these waste batteries have become appendages of some fake products in the market, thus affecting the market disorder. Taili Company has a complete set of environmental protection recycling and treatment processes. The advanced treatment technology is in a leading position in China. The professional recycling team and safe transportation, storage and disposal have greatly reduced the pollution of used batteries. Regarding the huge advantages of Taili Waste Battery Recycling Technology Company in treatment, Zhang Yongxiang said: "In battery treatment technology, we adopt safe, reasonable and environmentally friendly treatment processes and methods (roasting method, extraction method), and there is absolutely no secondary Pollution. First of all, we classify the recycled waste batteries according to their chemical composition. Ni-MH Ni-Cd batteries are a set of treatment processes, lithium-ion batteries are a set of treatment processes, lead-acid batteries are a set of treatment processes, and alkaline batteries are a set of treatment processes. At the end of each process, the raw materials necessary for batteries and nickel hydroxide, lithium cobaltate, lead oxide, graphite powder, etc. are extracted, achieving zero emission treatment of waste batteries and energy recycling." It is understood that Taili has also co-founded a scientific research room with several universities. There are now 3 invention patents for battery recycling and reuse, and 2 patents have been transformed and mass-produced. Be prepared to welcome that the number of new energy vehicles will reach 500000 by 2011 and more than 1 million by 2015. As the recycling of used batteries in its terminal industry, Taili has a very broad prospect. Facing this huge market, Taili has its own specific plan and timetable. In the interview, Zhang Yongxiang expressed to us his influence on the development of new energy vehicles on the battery recycling industry: "With the gradual expansion of electric products, power battery consumption has become the world's first battery consumption. What we have to do is to expand the recycling capacity and improve the processing capacity. It is planned that the processing capacity will reach 10,000 tons/year in 3 years, the recycling network will be more detailed, strive to expand to any part, and love to strengthen environmental protection education, let environmental protection knowledge go deep into the hearts of the people, form a conscious habit, organize professionals to enter major enterprises and schools to give lectures on environmental protection knowledge, so that more people can support us and support us. Our core competitiveness is to have these lovely environmental protection lovers. We cannot do without them, and the world cannot do without them." What role should the recycling of used batteries play when electric vehicles achieve zero pollution? And among them, how will Taili play such a role? Zhang Yongxiang gave the answer. "The development of electric vehicles only achieves zero emissions, not zero pollution. Only when the battery is in the scrapped period can it be recycled to achieve zero pollution in the true sense, recycle resources, and re-produce new batteries. The role played by Taili is a chain, allowing environmental protection to be recycled and resources to be recycled. We will continue to do a good job in this circular chain, and connect battery production and product manufacturers and consumers well. Form a benign running track." Zhang Yongxiang said. New energy vehicles are developing rapidly, but the recycling market at this stage has not yet fully emerged. However, Taili did not passively wait for the arrival of the market. During this period, he was well versed in "whoever has the industry standard, who has the industry's dominance" Zhang Yongxiang led Taili to take a solid step in advance on the battery recycling standard. Zhang Yongxiang said: "New energy vehicles have just entered the stage and will dominate the future. The service life of batteries is not 5-8 years as mentioned in the publicity. In fact, 3-4 years will enter the scrapping period. Therefore, we should complete the certification system of Taili recycling as soon as possible before the power battery enters the payback period on a large scale, and strive to introduce the concept of environmental protection recycling into the car at the beginning of production, so that the battery recycling standard is not blank. We have formulated this certification standard. We hope that the media from all walks of life will give strong publicity and support to make the awareness of environmental protection deeply rooted in the hearts of the people. We also hope that the community, retailers, enterprises and institutions, and government agencies will jointly participate in the establishment of recycling points-national participation. At the end of the interview, Zhang Yongxiang said: "with the change of the environment and climate, it is our bounden duty to advocate low-carbon environmental protection. The national government has also introduced various relevant policies to support the development of low-carbon environmental protection. Investing in and operating enterprises is to make money, but it must not be at the expense of the environment, otherwise no matter how much money you earn, it will be waste paper. We must respond to the call of the country and do something to protect the environment-leaving a blue sky and green space for future generations. It is our social responsibility to protect the environment, and it is our task to recycle used batteries. It is our advocacy to promote environmental protection and raise the awareness of the whole people. We should make battery recycling more systematic and professional, so that our network can be spread all over the world. Let everyone participate."



Help electric vehicles truly achieve zero pollution

-Dialogue with Zhang Yongxiang, General Manager of Shenzhen Taili Waste Battery Recycling Technology Co.,Ltd. HelpingEVSonRealZeroPollution -Dialoguewithzhangyongxiang,GeneralManagerofTeleDisusedBatteryRecycledTechnologyCo.,Ltd. Waste battery recycling is one of the extended industries of electric vehicles. Zhang Yongxiang, General Manager of Shenzhen Taili Waste Battery Recycling Technology Co.,Ltd. recently analyzed the situation of this industry. Q: Taili's basic situation. Our company was founded in 2007, is a professional engaged in renewable energy and high-tech research and development of environmental protection enterprises. It has been awarded the national circular economy pilot enterprise, the national innovative pilot enterprise, and the national high-tech industrialization demonstration project, and has become one of the leading enterprises and pioneers of China's circular economy and low-carbon manufacturing. The company's R & D center has a research and development team with the most cutting-edge technology for battery recycling, ensuring that the company can effectively realize the industrial transformation of new technologies. Q: What are the main hazards of used batteries? Trials conducted by the U.S. government and the California Environmental Protection Agency have shown that cadmium in one battery of an old mobile phone can severely contaminate 60000 liters of water, equivalent to a person's lifetime, that could fill three standard Olympic swimming pools. One battery rotten in the ground can make a square meter of land lose its use value. Waste batteries discarded or improper stacking, too long will cause mercury, nickel, lead, chromium and other harmful substances scattered. The damage of these harmful substances to groundwater sources and soil is huge. The lead contained in the battery can damage the blood circulation, digestive system and nervous system, and cadmium can cause severe diseases such as kidney damage and osteomalacia. Q: What is the best way to deal with used batteries? From the perspective of environmental protection and resource management, the best way to deal with used batteries is to recycle them. Our company is a high-tech waste battery processing and renewable energy utilization company. Its main business is to recycle electronic waste, waste batteries and other waste resources to recycle high-tech products. Advanced processing technology is adopted in the recycling process to minimize the environmental pollution caused by battery cadmium and other harmful substances, and useful substances in waste batteries are decomposed and used in battery reproduction, such as cobalt, nickel, manganese, lead, zinc, etc. as raw materials for reproduction. So as to maximize the harmless treatment and recycling. The "green" recycling of used batteries is realized, which saves a lot of resources for the country. In line with the enterprise spirit of "science and technology create green life", with the help of advanced technology and equipment and scientific management mode, Taili waste battery recycling technology Co., Ltd. has developed into one of the largest banner enterprises in China with the integration of waste lithium, waste nickel, waste cobalt, recycling and sales. Q: What are the problems in the recycling and disposal of used batteries in China? What are the international experiences worth learning? At present, there are no relevant laws and regulations on the recycling and disposal of used batteries in China, because there are no rules to follow and there is no way to follow, so the pace is not unified enough. At present, a series of paid and free local recycling activities and methods have appeared in various places, such as rewarded recycling, old-for-new, and public welfare recycling, which have a certain effect, but after all, they do not have the compulsory power of laws and regulations, and the effect is limited. Moreover, the above-mentioned recycling activities will eventually return to a more difficult problem-that is, the transportation, storage and disposal of waste batteries. As toxic and hazardous waste, waste batteries should belong to the scope of work of the environmental protection department, but it is mixed with urban domestic waste entering the environmental sanitation department, so waste batteries have become a big problem for the environmental protection and environmental sanitation departments. Due to the recycling and treatment technology of waste batteries in my country The development and research work started relatively late, and the citizens are not aware of environmental protection, and their understanding of the hazards of waste batteries is more general, therefore, a series of problems such as small amount of recycling, no standard for transportation and storage work restrict and limit the development of recycling and processing work. Therefore, the most urgent problem is the need to introduce a waste battery recycling and disposal of laws and regulations. In this regard, the experience of the United States is worthy of our reference. It is the country with the most detailed legislation on the environmental management of waste batteries. It has not only established a complete waste battery recycling system, but also established a number of waste battery treatment plants. Publicize and educate the public to let the public consciously support and cooperate with the recycling of waste batteries. Japan's Hokkaido Nomura Xingchan Company purchases 13000 tons of waste batteries from the whole country every year, accounting for 20% of the waste batteries in the whole country. The collection method is 93% through non-governmental environmental protection organizations and 7% through various manufacturers. Germany requires consumers to send used dry batteries, twist-button batteries and other types of batteries to shops or waste recycling stations for recycling. Shops and waste recycling stations must unconditionally accept used batteries and transfer them to manufacturers for recycling. Q: As a waste battery recycling company, what is the purpose of your participation in this electric vehicle conference? What are your plans? Electric vehicles are the direction of future automobile development, and will extend a large number of related industries. Waste battery recycling is one of the terminal industries of electric vehicles. If you think about it, the biggest advantage of electric vehicles compared with traditional fuel vehicles is energy saving, and the other is environmental protection. If you don't burn oil, there is definitely nothing to say about energy saving. But what about environmental protection? Many electric car companies say they achieve zero emissions. On the surface it seems so. No oil, electricity, no exhaust emissions, looks like zero emissions. But they forgot one fundamental problem-the battery. Car batteries have a life span. Now electric vehicles have just started and are rarely used. When they become popular in the future, there will be a prominent problem. If a large number of waste batteries are not handled well, they will pollute the environment, and electric vehicles will not be able to achieve Zero emissions in the true sense. We are attending the electric vehicle conference this time to tell these electric vehicle companies that if you are not ready to deal with the large number of used batteries that will be generated by electric vehicles in the future, then our Taili company will help you relieve your worries and help you achieve Zero pollution in the true sense. Q: Do you have any experience in dealing with on-board batteries? What do you think of your prospects? In fact, we have had successful cooperation with some domestic and foreign electric vehicle manufacturers in dealing with used on-board batteries over the past few years, and have mature experience and conditions. China is the world's largest automobile market, and it will become the world's largest electric vehicle market in the future. Therefore, as its terminal industry, waste battery recycling has broad prospects and great achievements. “IfyouarenotreadyyetfordealingwiththelargeamountofdisusedbatteriestobeleftbyEVS,ourcompanywillhelpyougetridoftheworriesbehindandachieverealzeropollution.



Facing the waste battery harm we how to be good

1. Types of batteries: Batteries mainly include disposable batteries, secondary batteries and car batteries. Disposable batteries include button batteries, ordinary zinc-manganese dry batteries and alkaline batteries, and disposable batteries contain mercury. Secondary batteries mainly refer to rechargeable batteries, which contain heavy metal cadmium. Automobile waste batteries contain acid and heavy metal lead. 2. The hazards of waste batteries: mercury discarded in natural batteries will slowly overflow from the battery, enter the soil or water source, and then enter the human body through crops, damaging the kidneys. Under the action of microorganisms, inorganic mercury can be converted into methylmercury, which gathers in the body of fish. After people eat this fish, methylmercury will enter human brain cells, causing serious damage to the human nervous system. Will go crazy to death. The famous Japanese Minamata disease is caused by methylmercury. Cadmium exudates and pollutes the land and water, and eventually enters the human body to cause damage to the liver and kidneys. It can also cause bone weakness and severe bone deformation. Automobile waste batteries containing acid and heavy metal lead leakage to nature can cause soil and water pollution, and ultimately cause harm to people. Recycling waste batteries: The popularity of household appliances and the increase in types have led to a sharp increase in battery usage. Waste batteries mixed in the garbage, not only pollute the environment, but also a waste. The annual consumption of batteries in the country is 3 billion, and 740 tons of copper, 16000 tons of zinc and 97000 tons of manganese powder are lost due to no recovery. We should separate used batteries from other garbage and collect them for recycling. Many countries attach great importance to the recycling of waste batteries. Many stores in Germany require customers to return used batteries to the store when buying batteries. Japan's proprietary sorting box collects different waste batteries. 4. Knowledge Card: Do you know "pain disease"? Both "pain disease" and "Minamata disease" are industrial pollution diseases that occur in Japan. This is due to the fact that industrial wastewater containing cadmium or mercury contaminates the soil and water sources and enters the human food chain. "Minamata disease" is mercury poisoning, patients due to the accumulation of large amounts of methylmercury in the body and the occurrence of brain central nerve and peripheral nerve damage, mild hand and foot paralysis, severe death. "Pain disease" is cadmium poisoning, patients with hand and foot pain, all over the body are prone to fracture. People who have this disease are always shouting, "It hurts! It hurts!", Until death, so called "pain disease". Since ordinary dry batteries contain these two toxic elements, the battery is always lurking in pollution from production to waste. Battery recycling is imperative! I deeply understand the harm of used batteries, but how many people can actually participate in the work of recycling used batteries? I will gather up the used batteries and throw them in when I see the recycled boxes. When I was in college, there was a waste battery recycling box under each dormitory building, but after graduation, I found that this recycling box did not know where it went. There are no such devices near the home. Can you tell me where I can recycle used batteries? Together to actively participate in environmental protection, together with the implementation of waste battery recycling work!



Hazards of waste batteries

One button battery can pollute 600000 liters of water, which is equal to the amount of water a person drinks in a lifetime. A battery rotting in the ground can make a square meter of land lose its use value, so it is not too much to describe a section of used batteries as a "pollution bomb. Our daily use of ordinary dry batteries, mainly acidic zinc manganese battery and alkaline zinc manganese battery two categories, they all contain mercury, manganese, cadmium, lead, zinc and other metals. After the waste battery is abandoned, the battery shell will slowly corrode, and the heavy metals in it will gradually seep into the water and soil, causing pollution. The biggest feature of heavy metal pollution is that it cannot be degraded in nature and can only be eliminated by purification. The harm of used batteries is mainly concentrated in the small amount of heavy metals contained in them. The performance of metal type hazards: manganese-manganese excessive manganese accumulation in the body caused by neurological dysfunction, early performance for comprehensive sexual dysfunction. The heavier ones have heavy legs, monotonous language, rigid expressions, indifferent feelings, and are often accompanied by mental symptoms. Zinc-zinc salts can cause protein precipitation, the skin of the mucosa have a stimulating effect. When the concentration in water exceeds 10-50 mS/L, it is carcinogenic and may cause chemical pneumonia. Lead: Lead mainly acts on the nervous system, blood circulation system, digestive system, liver, kidney and other organs. It can inhibit the anabolic process of hemoglobin, and can also directly act on mature red blood cells. It has a great impact on infants and young children. It will cause physical development in children. Retardation, chronic lead poisoning can lead to mental retardation in children. Nickel-nickel powder dissolved in the blood, to participate in the body circulation, has a strong toxicity, can damage the central nervous system, cause vascular variation, serious cases lead to cancer. Mercury-it is the most worth mentioning among these heavy metal pollutants. This heavy metal is really harmful to human beings. For a long time, when producing dry batteries in our country, a toxic substance-mercury or mercury compound has to be added. The mercury content in alkaline dry batteries in our country reaches 1-5%, and that in neutral dry batteries is 0.025. The mercury used in the production of dry batteries in the country every year has obvious neurotoxicity, in addition, it also has adverse effects on the endocrine system and immune system. In 1953, the Minamata disease incident that shocked the world in Kyushu, Japan, sounded the alarm of mercury pollution to mankind. Heavy metal pollution threatens human health. If humans ignore the control of heavy metal pollution, they will eventually swallow the bitter fruit brewed by themselves. Therefore, it is increasingly important to strengthen the recycling of used batteries.
