In recent years, the state has issued a variety of policy measures to standardize lead-acid battery processing and recovery, but reporters have developed in Jiangsu, Guangdong, Ningxia and other land, and the pollution in the process of processing and recovery is repeatedly. Especially on the recovery link, one side is a formal regenerative lead company generally "eat unsaturated", but the other side is a large number of waste batteries flow into "black". According to industry insiders, lead-acid batteries have severe lead, acid pollution hazards in processing and recovery, and the pollution incidents have exacerbated heavy metal pollution.

In order to effectively implement the worker's responsibility extension system, we should further improve the relevant policies and regulations, introduce environmental deposit returns, and perform classification and transportation of waste lead-acid batteries. Lead-acid battery processing pollution has repeatedly banned the lead in the lead in the company's lead in the existence of unwanted, over-term stacking and even illegal metastasis, and has become the key and difficulties of environmental safety supervision involving heavy metal pollution. In May of this year, the Ministry of Consumer Products Industry of the Ministry of Industry and Information Technology conducted a discovery of Jiangsu Shuzhai Battery Co.

, Ltd., and found that Jiangsu Shuzhai Battery Co., Ltd.

has serious violations of the "Standard Conditional Conditions of Battery Industry". Some lead processing workshops are not closed as required, and the processing area is not strictly separated from non-processing regions. The Jiangsu Province national control pollution source platform found that the company's self-monitoring measures updated in January 2017 show that the renovation of the rejuvenation of lead-acid battery manufacturing and waste batteries, belongs to heavy metal national control companies.

In addition to general pollutants, the industrial wastewater of the Harbor Battery contains heavy metal lead, total row, handmade and automatic monitoring pollutants, including COD, pH and lead. Lead is a heavy metal, lead and its compounds enter the human body, may cause harm to multiple systems such as nerve, hematopoietic, digestion, kidney, cardiovascular and endocrine, and even lead poisoning. There is environmental public welfare organization to sample the company's suspected wastewater, and commissioned a third part of the test qualification "Banshenmei Commodity Test (Shanghai) Co.

, Ltd." (referred to as "must test") test decomposition. The decomposition report of the Biwei test supply shows that the environmental public welfare organization is sampled in the outer wall of the rash battery, which is 2.

23, which is strongly acidic, heavy metal lead content is 8150 micrograms / liters. Phenomenon like lead-acid battery processing links is not an example. In Jiangxi Yifeng Industrial Park, according to media reports, a battery factory open-air sludge pool is full of sewage slag lead mud, privately filled with lead waste.

According to the environmental protection department of the Eastern Province, they have repeatedly remedied the lead-acid battery and regenerated lead industries, which are subject to economic benefits and technical conditions, and the disposal of serious harsh waste is related to the actual appearance. The company's lead in the company has no problem, and has become a key and difficult to involve environmental safety supervision involved in the company. A large number of waste batteries flow into the "black market" due to limited recycling capacity, regulatory vulnerabilities, etc.

At present, the disorderly status of the waste lead-acid battery recovery industry still exists. There are still more than half of the provinces that have lack of waste lead-acid batteries recycling qualifications. Entering the processing workshop of Ningxia, Ningxia, Ningxia, Ningxia, Ningxia, and the reporter saw that a piece of waste lead-acid battery is entering a "big can" through the conveyor belt, and the battery appearing in the process.

The acid solution is cleaned by water to solve the system's layer cleaning. According to the analysis of Ningxia Environmental Protection Hall, there are currently two qualified lead-acid batteries recycling, solving the company, with a total settlement capacity of 180,000 tons / year. According to estimates, Ningxia has about 80,000 tons of waste batteries every year, but the two companies can only recover five or 60,000 tons per year, and quite some used batteries still flow to "black market".

The reporter survey found that there is an incidence of illegal workshop lead recovery points in recent years. Such as June 2017, Jiangsu Nantong Tongzhou District environmental protection, public security and other departments have cracked 5 environments that illegally dumped the waste of used lead-acid batteries; in January 2018, the Shanxi Provincial Public Security Department took off a waste lead-acid battery as raw materials. Criminal gang of disassembly, smelting, selling lead ingots "one dragon".

"The public security department has striied the" small workshop ", the company's business is very clear. Yang Wenli, Chairman of Ningxia Ruiyin Nonferrous Metal Technology Co., Ltd.

my country is the world's largest lead-acid battery processing country and exporter. According to the latest announcement of the NDR, in 2017, my country's lead production was 4.72 million tons, accounting for 44% of the total lead output of lead.

The waste-recovery of waste lead-acid batteries has been long, and the "Battery Industry Heavy Metal Pollution Comprehensive Prevention Measures (Draft for Comment)" promulgated in the 2010 Department of Working, it is pointed out that the waste lead-acid batteries of developed countries such as Europe, United States, Japan. The recovery rate has exceeded 90%, while my country's organized recovery rate is less than 30%. In fact, in order to standardize the recovery of waste lead-acid batteries, in recent years, the relevant departments have issued a variety of policy measures.

However, the current disorder status of the waste lead-acid battery recovery industry still exists. The survival space of formal recycling company was squeezed, and the "inferior coin" is formed in the scope of waste lead-acid battery. Some illegal "small workshops" with misconduct and regular companies grab business.

The reporter survey found that the following aspects result in the formation of "inferior coins". First, formal recycling solves the company's processing cost. Yang Wenli said that in the fixed asset investment, the company's environmental protection equipment accounts for 40%, plus operation and maintenance, depreciation and other factors, and environmental costs account for more than 20% of the total cost of renewable lead recovery.

And illegally "small workshop" rely on an ax, a stove is enough, almost zero, so they can significantly increase the purchase price, and the regular company grab business. Second, there is no cooperation between the seizures. Respondents believe that the wide range of waste lead-acid battery is large, and the relevant departments singles are difficult to have.

The current regular car 4S shop waste cell recovery is relatively standardized, but the lack of car maintenance points is disabled, the scale is different, the quantity Numerous, this also increased the regulation of management departments. Third, consumer recycling is weak. The person in charge of the Guangdong Circular Economy Association said that due to the lack of harmful understandability of waste lead-acid batteries, it is impossible to actively participate in the recovery of waste lead-acid batteries, resulting in many battery recycling equipment in life.

In addition, many consumers have no awareness of illegal recycling channels. In recent years, the establishment of a processor's responsibility extension system has become a consensus on the processing of lead-acid battery recovery, some local governments, social organizations, companies, etc. are actively implementing the implementation of lead-acid battery processing.

As the market demand continues to Zhang Da, my country has become the world's largest lead-acid battery market, and the number of waste lead-acid batteries that have occurred each year is more than 3 million tons. There are many increasing states, and the market potential of waste-lead-acid batteries will not be underestimated. In each battery, the lead pole plate accounts for 74% of the share, and sulfuric acid accounts for 20%.

For a long time, due to the complete recovery system in my country's waste lead-acid batteries, most of the waste lead-acid batteries finally flowed into the illegal small workshop for simple disassembly, the lead pole leaving, the acid-liquid pen is straight, the comprehensive utilization is extremely low , Damage to the human body and ecological environment. In my country's 3.3 million tons of waste lead-acid batteries in China, the proportion of regular recovery is less than 30%, buried in pollution hidden dangers.

In recent years, the establishment of a processor's responsibility extension has become a consensus for the treatment of lead-acid battery recovery, and its core is through the guidance of product processors to undertake the waste and resource utilization responsibility after abandonment, and the excitation process will implement product source control, green Processing, thus maximizing resource utilization efficiency in the full life cycle. In December 2016, the General Office of the State Council issued the implementation of the "Processing Outlook", for the implementation of 4 types of products such as lead-acid batteries, and the establishment of the product full life cycle traceability system, support " Improve recovery rates in old-rehabilitation, and explore lead-acid battery processors aggregation collection and cross-regional transfer methods. In July 2017, the National Development and Reform Commission held a seminar on the implementation of the lead-acid battery processingter's responsibility extension system, discussed the improvement and approach of improving statistics, verification, evaluation, supervision and target adjustment, and proposing the recycling goals and analysis implementation.

In order to promote lead-acid batteries to standardize recycling, some local governments, social organizations, companies, etc. are actively promoting the implementation of lead-acid battery processing responsibility extension through different levels.
