Problem 2: how to do cell phone battery China's annual production of batteries has reached 14 billion to 15 billion, the annual consumption of 9 billion, accounting for a quarter of the world's output. waste batteries casually discarded or improperly buried, too long will result in the dispersal of mercury, nickel, lead, chromium and other harmful substances. These harmful substances on the groundwater source and soil damage is huge, a one battery leachate is enough to make 1 square meter of soil loss of agricultural value, and a button battery can pollute 600,000 liters of water (which is a person's lifetime of water consumption). Obviously, the recycling and disposal of old batteries can never be "small" view. The hazards of waste batteries are obvious to all ****, if this is indifferent, the ultimate injury can only be our own homes. Only you and I work together, starting from me, so that environmental protection has become a habit of life, in order to make the waste battery recycling work smoothly.
In our country, the recovery of waste rechargeable batteries, must be manually sorted, pick out the nickel-cadmium batteries, nickel-metal hydride batteries and lithium batteries, and then were loaded into sturdy plastic drums, sealed and placed in the rain, sun, fire, theft prevention of the specialized warehouses for safekeeping. It is estimated that the collected waste batteries need to be stored temporarily for a certain period of time before they can be processed. Disposable dry batteries need to reach a certain amount of resource reuse before there are profits to be made. The current treatment countermeasure is to the sanitary landfill site for centralized and harmless landfill, to be technologically mature, and then take out the recycling.
It is understood that, according to the service life of the battery and electronic equipment update rate estimates, Shenzhen each year the number of waste rechargeable batteries generated is quite alarming, reaching 50 ~ 100 tons / year. Waste battery pollution in the heavy rechargeable batteries, they contain lead can damage the blood circulation system, digestive system and nervous system, cadmium can cause kidney damage, bone softening and other serious diseases. Because of the potential heavy metal pollution and organic pollution, waste battery pollution in recent years has aroused widespread concern among the public, the media and environmental management departments, developed countries are very positive attitude towards waste battery recycling:
Japan: Nomura Nomura, Hokkaido, the company purchased from the country's waste batteries amounted to 13,000 tons per year, accounting for 20% of the country's discarded batteries, the collection of 93% of the way through the civil The collection method is 93% through private environmental organizations and 7% through manufacturers. In the past, the main recovery of mercury, but now Japan's domestic batteries do not contain mercury, the main recovery of battery shells and the "black" raw materials, and secondary product development and manufacturing, such as one of the products can be used for television tubes.
Germany: consumers will be required to use up dry cell batteries, button batteries and other types of batteries sent to the store or waste recycling station for recycling, the store and waste recycling station must unconditionally accept the used batteries, and forwarded to the manufacturer for recycling. Waste recycling stations and manufacturers generally only collect batteries containing cadmium, mercury and toxic chemicals, while 90% of ordinary zinc-carbon batteries and aluminum-magnesium batteries are disposed of in landfills or incinerated as household garbage.
Switzerland: There is a factory that treats old batteries by heat treatment, grinding them up and sending them to a furnace to be heated to extract the volatile mercury and zinc, which are precious metals. 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 and obtain 780 tons of ferromanganese alloy, 400 tons of zinc alloy and 3 tons of mercury.
The United States: the most detailed legislation in the environmental management of waste batteries in a country, not only the establishment of a comprehensive waste battery recycling system, and the establishment of a number of waste battery treatment plants, and at the same time unremitting publicity and education to the public, so that the public consciously support and cooperate with the recycling of waste batteries.
Question 3: How do you deal with cell phone batteries? There is no specialized waste battery treatment plant in China, even if the recycled batteries are concentrated in landfills, resulting in greater pollution. Secondly, now the waste battery, most of the low mercury or mercury-free, will not have much impact on the environment, so, as ordinary garbage disposal can be (I am quoting the words of the environmental protection experts) It should be noted that the cell phone batteries, button batteries, rechargeable batteries, there is still a very high level of pollution, must not be thrown anywhere!
Question 4: What about end-of-life cell phone batteries? Cell phone batteries contain cobalt with extraction value, should not be simply classified or landfill disposal
According to authoritative data, as of September 2002, China's cell phone users have nearly 200 million. Usually, a cell phone in its service life can be configured two to four cell phone batteries. In this way, two hundred million cell phones need the number of batteries is a huge number!
In addition, cell phones are updated frequently, and almost every cell phone has a specific battery to match. After a cell phone is eliminated, all the accessories, including the battery, will be completely "abandoned". If a piece, ten pieces, a thousand pieces of waste cell phone batteries littered everywhere on the environment will not cause much harm, then a hundred million pieces, a billion pieces?
The Henan Provincial People's Congress, Zhengzhou Environmental Protection Science Research Institute, director of the science room Sun Zhongdang said that the old cell phone (refers to the color screen phone before the cell phone models, the possibility of updating this phone is the largest) batteries are divided into three kinds: nickel-cadmium batteries, nickel-metal hydride batteries and lithium batteries, the new cell phone more than the use of lithium batteries. But no matter which type of cell phone batteries, which contain metal elements that can cause harm to the environment. However, unlike ordinary batteries, cell phone batteries also include cobalt, which has extraction value. Therefore, for the treatment of used cell phone batteries, should not just be like ordinary batteries as a simple classification and deep burial treatment, but should be actively recycled. The recyclable symbols marked on cell phone batteries from various manufacturers also indicate that such batteries are encouraged to be recycled.
A huge number of treatment is outdated
In Zhengzhou City, Green City Plaza, Dixon, Dongxin customer service center, Nokia repair center and other places, the reporter randomly interviewed 50 people. 93.75% of them were asked about the disposal of used cell phone batteries, are blankly shaking their heads, 80% of them said that the final will be used cell phone batteries like ordinary garbage thrown away; another 6.25% of the people said that the battery with the cell phone together with the sale of the recycler.
When the reporter asked, if there is a special recycling device for used batteries, are you willing to take the initiative to put the used batteries into it, 62.5% said yes; 12.5% said if there are some incentives to consider going to put; another 18.75% said if the recycling device is more and more convenient, willing to put it on the hand.
At present, Zhengzhou's second-hand cell phone recycling market is very lively, everywhere you can see vendors holding "cell phone recycling" signs. So this market can "take in" used cell phone batteries? The reporter asked the middle of the road 10 recycling of old cell phones, of which 9 said that the waste battery is not useful, not willing to buy a separate old cell phone batteries, only one claimed to be specializing in the purchase of old cell phone batteries said they are willing to buy, but as long as a few better sell the "beautiful goods".
Recycling of second-hand cell phone vendors are not willing to recycle cell phone batteries, those cell phone dealers, agents are willing to recycle used cell phone batteries? In Zhengzhou University near the north door of some cell phone stores, when the reporter asked the sales staff "whether to recycle used cell phone batteries", the vast majority of people gave a strange look, and some people even asked: "Used batteries of course, is thrown at home, never heard of recycling. " There are also salespeople who say they've never encountered a customer asking such a question, so they haven't thought about recycling the matter.
Throughout the interview, the reporter only found two stores willing to recycle used cell phone batteries, one is China Mobile Communications Erqi Road, a business hall, they said they can use used batteries against 20 yuan, but the premise is to buy the business hall of the cell phone battery. Another is the Nokia cell phone repair department. However, unfortunately, in this repair department in a marked "cell phone recycling, battery recycling, charger recycling" in the words of the recycling box, which is stuffed with all the snacks bag, there is no cell phone and its accessories, and the box looks like a long time no one asked for it.
From the reporter's investigation above, we can see that most of the waste cell phone batteries around us are in the garbage transfer station, and some of them will flow into the hands of unscrupulous vendors with the old cell phone, and then after refurbishment, they will be listed on the market to cheat consumers.
Lack of correct recycling methods
Reporters interviewed the environmental protection department, learned that used cell phone batteries contain metal elements with extraction value. However, due to the lack of proper recycling methods and the lack of fully established recycling channels, the recycling of waste batteries there are still many problems.
According to Mr. Wang of the Zhengzhou Environmental Protection Bureau Information Center, the earliest battery recycling in Zhengzhou is responsible for by the Zhengzhou Environmental Protection Bureau, but now the Sanitation Department is responsible for battery recycling. The Sanitation Department will transport batteries (all types) to a deep pit for landfill disposal. At present, the state has not introduced ...... >>
Question 5: What should be done with the unusable waste batteries on cell phones? Battery recycling has been a big problem, the best way is to see which shopping malls in front of the recycling battery box to put in, unified management, unified floating recycling. Although some of the trouble but the country and the people ~
Question 6: How to deal with waste cell phone batteries? 10 points Keep your own, or do a little modification of their own even a small fan small bulbs and so on, or throw the trash
Question 7: waste cell phone waste batteries need to be dealt with how to get rid of has been exempted from the proposal does not unify the centralized collection, dispersal of discarded.
Question 8: How to deal with old cell phone batteries? General neighborhoods have special boxes for storing waste batteries, or, the roadside trash cans also have a grid for batteries.
Question 9: It is said that the waste cell phone lithium batteries can not be thrown, that should be how to deal with how simple, environmentally friendly treatment of waste batteries?1 to the neighborhood committee 2 in the hundred seems to have recycling of old batteries in exchange for gifts. 3 to the waste recycling station. Hazards of used batteriesHazards of used batteries: The hazards of used batteries are mainly focused on the small amount of heavy metals contained in them, such as lead, mercury, cadmium, etc. These toxic substances enter the human body through various ways. These toxic substances enter the human body through various ways, long-term accumulation is difficult to exclude, damage to the nervous system, hematopoietic function and bones, and can even cause cancer. Lead: nervous system (neurasthenia, numbness of hands and feet), digestive system (indigestion, abdominal cramps), blood poisoning and other lesions. Mercury: Altered mental status is a major symptom of mercury poisoning. Rapid pulse, muscle tremors, lesions in the mouth and digestive system. Cadmium and manganese: mainly harm the nervous system. Waste batteries pollute the environment through: the constituent materials of these batteries are sealed inside the battery shell during use and do not affect the environment. However, after long-term mechanical wear and corrosion, making the internal heavy metals and acids and alkalis, etc. leaked out into the soil or water, it will enter the human food chain through various ways. The process is briefly described as follows: pool soil microorganisms animal circulation dust crops food human nerve deposition morbidity . Experts believe that due to the battery pollution has a long cycle, hidden and other characteristics, its potential harm is quite serious, improper handling will also cause secondary pollution. According to Dr. Yang Yifu, some farmers in a coastal province of China in the recycling of lead-acid batteries in the lead, because of improper recycling treatment, containing lead and sulfuric acid waste liquid poured, not only caused lead poisoning, but also so that local crops can not grow. A one battery rotten in the ground, can make 1 square meter of soil permanent loss of use value; A button battery can make 600 tons of water pollution, equivalent to a person's lifetime of drinking water. One button battery can contaminate 600,000 liters of water, equal to the amount of water a person consumes in a lifetime. A battery rot in the ground, can make a square meter of land loss of value, so a section of used batteries as a "pollution bomb" is not excessive. Our daily use of ordinary dry batteries, mainly acid zinc-manganese batteries and alkaline zinc-manganese batteries of two types, they contain mercury, manganese, cadmium, lead, zinc and other metal substances, waste batteries are abandoned, the battery shell will slowly corrode, which will gradually seep into the water and soil, heavy metal substances, resulting in pollution. The most important characteristic of heavy metal pollution is that it cannot be degraded in nature, and can only be eliminated through the purification effect. The hazards of used batteries are mainly concentrated in the small amount of heavy metals contained in them Metal type Hazardous manifestations Manganese Excessive accumulation of manganese in the body causes neurological dysfunction, the early manifestation of comprehensive functional disorders. In more severe cases, there is a dullness of the legs, monotony of speech, dullness of expression, and emotional indifference, often accompanied by psychiatric symptoms. Zinc Zinc salts can precipitate proteins and have a *** effect on the mucous membranes of the skin. It is carcinogenic when present in water at concentrations greater than 10-50 mSv/l, and may cause chemical pneumonitis. Lead: lead mainly in the nervous system, blood system, digestive system and liver, kidney and other organs can inhibit the synthesis and metabolism of hemoglobin process, but also directly on the mature red blood cells, infants and young children have a great impact, which will lead to children's physical development is delayed, chronic lead poisoning can lead to children's mental retardation. Nickel Nickel powder is dissolved in the blood and participates in the internal circulation, it has strong toxicity, it can damage the central nervous system, cause vascular degeneration, and in serious cases, lead to cancer. Mercury It is the most noteworthy of these heavy metal pollutants, this heavy metal, the harm to human beings, is indeed not shallow, for a long time, our country in the production of dry cell batteries, to add a toxic substance - mercury or mercury compounds, China's alkaline dry cell batteries in the mercury content of 1-5%, neutral dry cell batteries 0.025%, the country's annual production of dry cell batteries used in the production of mercury content of 1-5%, neutral dry cell batteries 0.025%. The mercury used in the production of dry batteries every year in China has obvious neurotoxicity, in addition to the endocrine system, immune system and other adverse effects. In 1953, the Minamata disease incident that shocked the world and took place on the island of Kyushu, Japan, sounded an alarm for human beings about the pollution of mercury. Heavy metal pollution, threatening human health, human beings if you ignore the control of heavy metal pollution, and will eventually swallow the bitter fruit of self-brewing, therefore, to strengthen the recycling of waste batteries is increasingly important.
Problem ten: change the cell phone waste battery how to do General, the old battery do not just throw. Collected, there are specialized recycling of old appliances and so on, you can give people.
Earlier in the year to clean up the garbage, accidentally put the battery, into the fire, exploded. I was shocked, and I will never throw it away again.
