Used batteries to the pollution of the environment how? How to deal with is the science?
Shanghai is currently in accordance with the requirements of dealing with waste separation, waste battery is still as a specialized type of recovery. However, Environmental Science and Engineering Department of Tsinghua University's doctoral tutor Nie Yongfeng, a research has said that discarded batteries, mainly one-off small batteries, the pollution of the environment is right, unlike some people so serious.
To this end an interview with reporters in Shanghai Waste Administrative Division Chief Engineer Zhang Zhiqiang, he pointed out that Professor Nie Yongfeng research is credible. However, Shanghai is still devoted to the recovery of used batteries is more than a decade, combined with solid waste classification, Shanghai people have developed a habit of dealing exclusively with the battery, and Shanghai with the corresponding treatment facilities.
Zhang Zhiqiang said that in accordance with the findings of Professor Nie, the state has requested the production of battery manufacturers of mercury-free batteries. Therefore, the regular battery manufacturers in fact do not have specialized recycling, and if, after recovery there is no specific treatment, but later concentrated more harmful than dispersed discarded. However, there are many non-formal domestic manufacturers, they manufacture a wide range of batteries contain heavy metals, it will be very difficult security environment are protected. Therefore, there are certain specialized recovery necessary.
According to the city's Waste Management Department, the Shanghai about a year more than 30,000 tons of waste recycling batteries, fluorescent tubes, medicines, are concentrated to the Jiading district Zhu bridge the Environmental Protection Agency approved a landfill for hazardous waste landfill to deal with.
According to environmental protection in August 2008 and the Department of State Development and Reform Commission published list of hazardous wastes, the handling of used batteries is also somewhat ambiguous: on the one hand, family day-to-day use of used batteries can not deal with hazardous waste; On the other hand If used batteries from the classification of garbage out specifically, it is necessary in accordance with the Hazardous Waste Management.
Shanghai itself has a good recycling system expertise, members of the public to develop the habit of a special classification, it is therefore necessary to continue the work of the battery recycling expertise. Of course, the landfill approach is still very negative, there is no good will use. In Japan, all the used batteries are concentrated in Hokkaido, a factory, after the isolated spin-off of heavy metals, some of the other can be used as industrial raw materials on. However, Zhang Zhiqiang said that the domestic recycling of used batteries as thin profits, it is difficult to find a bear factory. (Shanghai People Xinhua June 12) (Editor: Dubbo)

Shantou City, Guangdong Province ------ Guiyu town, a wealth of e-waste through the town. Here is known as the world's largest e-waste dismantling bases, is the terminus of e-waste. Guiyu 28 in the village, 21 villages, more than 80% of the families directly involved in the work, they formed a family of hundreds of e-waste dismantling workshops to absorb tens of thousands from all over the country the workers here. Data show that the decomposition of these workers e-waste each year can reach 1.5 million tons. In these e-waste, there are more than 70% from the United States and other developed countries. These developed countries in flagrant violation of international "Control of Transboundary Movements of Hazardous Wastes and Their Disposal, Basel Convention," will be a large number of e-waste dumping to China, dumping to Guiyu. Well, these Guiyu e-waste on human health and the environment, what harm will it?
In 1200 before brushless alternators: The Unbearable Guiyu "polluter"
Some Guiyu way to deal with e-waste, known as the "19th century technology of the 21st century, refuse to deal with," In fact, the local adoption of "acid bath" to extract the e-waste in the way of precious metals, and in 1200 more or less the same process before; wash gold Factory smoke filled the air, in addition to washing Jinchang people around it is very difficult to outsiders, but also do not want to close.
"This is the hydrochloric acid, which is hydrofluoric acid, sulfuric acid that is, ... ... with a basin, the chip on the inside, erbium sulfate,burning, to burn the plastic chips, and then join together to wash Some are copper, iron ... ... and then some nitrate melt, and then through the other two processes, the powder can be precipitated. "Shantou City in Guangdong Province, Chaoyang District Guiyu a factory town, once the wash to Mr. Jin Zheli reporters about the process of washing gold.
Some Guiyu way to deal with e-waste, known as the "19th century technology of the 21st century to deal with garbage." In fact, the local adoption of "acid bath" (also known as "pickling") to extract the e-waste in the way of precious metals, and in 1200 more or less the same process before. It is understood that, in addition to access to second-hand market, the vast majority of Guiyu e-waste will be kept separate, the circuit board used a variety of chips, capacitors, diode and other components, reuse can be recycled; part of the needs of through the barbecue, acid bath, such as extraction of gold-plated, tin solder, copper and other metal frame, wire was copper from peeling or burning; plastic parts will be processed into a simple plastic particles made of plastic raw materials or artificial flower. It is precisely for these e-waste in the split, barbecue and the process of acid bath, a large amount of harmful substances to the environment caused by the very serious harm.
According to the survey, although there are different recovery Guiyu circuit boards, but usually the first step in the process of welding are removed. The circuit board on the solder pot on the stove in the coal-fired heating, until chips can be moved, and then chip out the collection (This process is commonly known as the local "plate grilled" or "barbecue").
Then, through the beat board to collect the fallen solder, and then after the sale of the collection of melting; the chips fall were classified, one for re-sale, and the other recovery of gold. When the vast majority of circuit boards have been collected, it will be sent to large-scale burning or acid recovery workshop, the recovery of the remaining metal. The last part of the combustion process will produce a considerable number of harmful substances, such as dioxins, beryllium, and polystyrene hydrocarbons (PAHs) and so on.
To remove the chip from the circuit board is the ultimate goal of recovery of precious metals, but the recovery method is the original acid bath: the aqua regia (25% pure nitric acid and 75% of a mixture of pure hydrochloric acid) in a small fire into the heated computer chips loaded with plastic bucket, stirring, shaking, which contained dissolved gold and other precious metals; a few hours later, by adding a chemical to separate gold, so that in the barrels at the end of precipitation, and then condensed into the paste "The mud,"into powder, the final melting for pure, shiny gold or gold tablets.
Volatile acid bath process will be a large steam-like acid gases, from faraway places can see the smoke. According to the local taxi driver, the washing gold site edge generally in the town of the bank, there are the outskirts of the town of Guiyu, in addition to washing Jinchang people around it is very difficult to outsiders, but also do not want to close. "That's not by, as if I went to the same shock." Recently, when the press strongly urge taxi drivers to wash gold field near the river, the smoke makes visibility became zero.
------ The survey found a way here to wash gold, and before the 1200 Persian alchemy invention of the aqua regia Yang Kazakhstan is basically similar to gold, but now extracted from the circuit board of the gold, acid dissolution need something more, process more complex, larger, and more pollutants generated.
Mr. Lee said that the work of washing gold on the long dry cough, go to the hospital examination, doctors said that we should not have done for too long, there are a lot of the stem this disease, will be poisoning the air-suction ... ... into all of your organs.
------ Habits, allow people to overlook the potential health risks. Guiyu way to break down the existing e-waste on human health in the end will be what impact the people engaged in this work do not understand this. In order to understand the person's state of health Guiyu, this reporter went to Guangdong Province, Shantou University Medical College,professor and her research team in the 5 years from numerous in-depth medical Guiyu town survey and consulting services.
said, in addition to the process of burning plate welding point lead inside the environment at high temperature into dust, so that these heavy metals in the dust, the part of the process of burning waste will cause a lot of persistent organic pollutants, such as dioxin. These persistent organic pollutants, through animal experiments proved cancer, will affect the newborn and children's growth and development. The survey findings revealed that Guiyu, the lead content in children, the human body of dioxins and other organic contaminants are much higher than other areas.
In the interview, Professor also repeatedly referred to the "irreversible" damage, meaning that once the existence of heavy metals such as lead in the human body, such as on the central nervous system caused by the injury, even after the way through a variety of heavy metals from the body to the, However, this injury is not always up.
Because people can not see the harm their health, said, so it is easy to negligent. However, this harm can be said to be fatal.
When 21st century technology can be used to deal with the 21st century rubbish?
Guiyu town government said that solving the problems of pollution, it is necessary to change for the sparse block to guide the standardization of production ,------
In the dismantling of used mobile phones in the hands of the main workshop, the reporters saw, the workers of the acquisition of the mobile phone without battery to fully open to the outside of the plastic, which categories of components, sub-put into the wall The 1600 yard box, waiting for buyers in the procurement, while the rest of the circuit board will also be sold to specialized workshops extraction of heavy metals.
Guiyu town mayor even said that workers are now operated by electric fusion machines welding points extraction cell phone accessories, more environmentally friendly technology. Circuit boards for computers are now how to extract, and even the mayor is only told reporters that they are burned out boards.
It is understood that the fire board as the extraction of precious metals before the board to carry out an important part of the initial decomposition, if the approach to change, those who engage in this work will have to put in each workshop to thousands of dollars to buy a hot, such high input so that the slow progress against the work.
For the existing problems Guiyu, Shantou City, said Wang Jianping, deputy director of the Environmental Protection Agency, Guiyu by decomposition of e-waste on the one hand, an increase of income, but also the largest victims of e-waste. A rough estimate, China's average annual end-of-life of the TV for more than 500 million units, about 600 million washing machines, refrigerators about 400 million units a year out of more than 1500 million units of discarded home appliances, this does not include the holdings of the rapid growth and a quick update electronic and communications equipment, including mobile phones, DVD and so on. Faced with a growing number of e-waste, Guiyu the need for a more advanced technology of the 21st century belongs to the 21st century to deal with these spam. He hoped that as soon as possible to promote e-waste recycling Guiyu base.
It is understood that in Guiyu in the next step in development planning, plans to invest 10 to dismantling modern industrial park building to change the current situation of the pollution. However, the great works can be granted when, this great when the funds can be worked out, how to strike a balance due to high input and low-yielding potential, which all have to face Guiyu. At present, both the town of Guiyu or their supervisors are not Shantou City has also a clear statement.
In March this year, the State Council's "Waste Electrical and Electronic product recycling regulations," an official release, the state of waste electrical electronic products eligible to be implemented to deal with licensing, manufacturers should have a sound Waste Electrical and Electronic products processing facilities and the corresponding sorting, packaging and other equipment.
