With the peak of the city, the traffic is increasingly congested, the convenient advantage of electric vehicles is reflected. The large number of electric vehicles have added to make their energy supply equipment battery use in geometric multiple. Because contain heavy metal lead, the production and recovery of the battery will contaminate the environment.
What is the current situation of current battery recovery reuse? What is the problem with the production and recovery of the battery? The reporter visited the electric car sales point, battery company, expert, and one explore. Do not standardize recovery "stubborn" in Yadi electric car Majiabao store, the electric car master Liu said to the reporter that his electric car was purchased in 2014. Just changed the battery a month ago.
When he was asked to go to the old battery, he said that selling the waste of waste at 30 yuan. In the new street, the West China East Street and other electric car sales points, the reporter did not see the waste battery recycling business, only to replace the new, each battery is up to 10 yuan to 20 yuan; and some waste acquisition station is 20 yuan Recycling of waste-old batteries to 40 yuan, with price "advantages". According to Zhang Yuxi, my country's Battery Industry Association, "Waste Battery Pollution Prevention and Treatment Technology Policy" stipulates that the manufacturer, importers and manufacturers of rechargeable batteries are responsible for the recovery of the old rechargeable battery.
Manufacturers who conduct recovery process must have recycling and disposal qualifications for environmental protection departments. "The life of electric vehicle battery is only 1 year to 2 years, and most lead-acid batteries are replaced 1 year after use. Currently recycling and disposal allowance can basically be said to be 'binding' distribution.
Only in Shanghai and other places have been distributed to the recycling work, the recycling license and disposal license are distributed. Beijing only has a professional treatment organization for the recovery of the recycling, landfill, comprehensive utilization of Beijing Ecological Island Technology Co., Ltd.
Battery recycling is difficult to fall, and the difficulties in the community collection station are difficult, many illegal, illegal companies have no professional disposal equipment, and high-priced waste batteries are difficult to do harmless disposal. In the recycling of waste storage, there is a phenomenon of the violation of the company, there is a 'small workshop, the small company can't manage', causing the battery recovery to become the 'tutrain'. "Zhang Yu said.
Zhang Yuxi interprets the harm of battery unregistered recycling disposal. "The annual number of waste batches exceeds 2.6 million tons, nearly 80% of the waste battery flows into the illegal recycling and processing links through individual commercial trafficking, Beijing electric bicycle has exceeded 3 million, 95%, using battery, all year round Lead-acid battery exceeds 20,000 tons.
The battery component includes a lead plate, an acidic electrolyte and a plastic housing. Many small business dealers only recycle lead, discharge the acid, and sell lead to some illegal smelters, causing 2 pollution, and low resources. The acid solution will cause water, soil pollution.
The environmental protection facilities are lacking during the illegal smelting process, and the smelting process will cause air pollution. In an environment where the human body has a high level of lead content, it will cause exceeding the standard and even lead poisoning, damage the brain nervous system, and will also affect hematopoietic function and kidney and bones. "Zhang Yuxi said.
Since there is a number of lead-acid battery production companies in my country, small and medium-sized corporate production technology and pollution control are still using backward process technology, and the establishment of special engineering technology is carried out for recycling of battery recovery. Professional management is imperative. On June 13, the National Environmental Protection Battery Production and Recycling Pollution Control Engineering Technology was established in Zhejiang Governor Xingxian.
Yang Tieheng, deputy director of the Ministry of Industry and Information Technology, and the introduction of the "Economic Daily" reporter: "Engineering Center will actively promote battery internalization into the battery, reducing the amount of pollutants in the production process; strengthening the raw materials related to metal battery products Alternative; at the same time, it will establish waste storage battery regeneration and utilization technology equipment demonstration project, speed up the development of waste battery machinery and split technology and equipment. By encouraging large smelting comprehensive companies to engage in the regenerative use of waste batteries, it will establish more than 50,000 tons of production capacity for 1-2 years, and the lead recovery rate is greater than 98% of the waste battery machinery dismantling, broken, sorting, and regenerative utilization technology. Equipment application demonstration project, improve the resource utilization technology level of waste storage, to establish a technical support for the establishment of a standardized waste battery recovery system supply technology.
"New technology promotes" green revolution "my country currently produces more lead-acid batteries to produce a production process, and companies that use internalization into production plates account for about 5%, and use internalization into production batteries to improve battery performance, energy saving Emission reduction, reduce production costs. Conventional cadmium-containing externalization is more diluted in the use process, and it is easy to fill the drum in high temperature seasons, and the leakage that is damaged during use in improper and recovery will cause pollution. In 2012, the Ministry of Industry and Information Technology and the Ministry of Environmental Protection explicitly stipulates that it should be eliminated at the end of 2013 with backward processes and more than 0.
002% of the cadmium-containing battery companies should be eliminated at the end of 2013. As the engineering technology center, Changxing County local company Chaoyu Group has studied non-cadmium internalization technology capable of solving the pollution problem of battery production, and has obtained the "green pass" of the production of batteries. According to Liu Xiaowei, the Dean of the Superwei Group Research Institute, the cadmium internalization has cancered the precipitation of the traditional foreign technology, and the charging, water washing, anti-oxidant treatment and 2 drying were also removed.
Process operation, saving a large number of work hours and energy consumption, reducing labor intensity, reducing 15% of employees; Cost, reducing emissions of acid fog and wastewater. Not only greatly reduces the cost of corporate environmental governance, but also effectively improves the consistency of the product, so that the battery quality is significantly improved. "No cadmium internalization is reduced by 90% of water, 28.
5% power saving, 15% reduction in cost reduction, 50% reduction in acid fog discharge, 50% per 6-DZM-12AH battery can reduce the total cost of 0.8 to 1 Yuan. Internalization to cadmium is both conducive to the company, conducive to the environment, more conducive to consumers.
The Chaowa Group now saves 4 million tons of industrial water every year. If cadmium internalization technology can be promoted in the battery industry, reduce more than 9 million tons of heavy metal waste water per year, reduce heavy metal lead emissions; reduce heavy metal sewage treatment The fee investment is nearly 1 billion yuan, indirect benefits and direct benefits of 1.5 billion yuan, which has very important promotion and promotion of green development of clean production and environmental protection and energy saving and emission reduction of my country's battery industry and green development throughout the industry.
"Liu Xiaowei said. In the battery recovery and reuse, the Super Will Group explores the "Atomic Economic Law", let the lead in the waste battery become available raw materials, realize local recycling, production in place. Zhou Mingming, chairman of Chaowei Group, is introduced that atomic economic france is a new recycling method with the current domestic and foreign waste lead-acid battery "heat treatment" and "wet treatment", through the atomic economic reaction, chemistry method will waste The battery is converted into direct use of lead powder, no dust, exhaust gas, wastewater discharge during treatment, and the waste sagging of the waste is 5% to 10% of the traditional process, and the recycling rate is more than 99%, and the energy consumption is only 50 of the traditional process.
%, Realizing the recycling process of waste storage, low recovery, high-pollution complex processes to low energy consumption, high recovery, low pollution green process transition. "The project is current 'speed change", from Nissan 10 kilograms of lead powder 200 kilograms, currently recovering 50,000 tons of waste battery production lines in the design, the goal is to build the world's first waste battery recovery high value Demonstration line. Zhou Mingming said.
