Technical specifications for pollution prevention and control throughout the life cycle of lead-acid batteries

　　In order to promote the progress of clean production and pollution prevention technology of lead-acid battery manufacturers and recycled lead enterprises, establish and improve the lead-acid battery recycling system, and standardize the collection, transfer and storage of waste lead-acid batteries, the Shandong Provincial Environmental Protection Department organized the preparation of the "Lead Technical Specifications for the Prevention and Control of Pollution Throughout the Life Cycle of Acid Batteries (DB37/T 2374-2018), which has been issued by the Shandong Provincial Quality Supervision Bureau and will be implemented on September 17, 2018. In order to facilitate the public to fully understand the background, main ideas, technical content, etc. of the formulation of this standard, the following interpretation is provided:

　　1. Why is it necessary to compile the "Technical Specifications for Pollution Prevention and Control throughout the Life Cycle of Lead-Acid Batteries"

　　The total output of the lead-acid battery industry in Shandong Province in 2016 was 15.5 million kVA, ranking 9th in the country. The overall pollution prevention and control level of enterprises is still low, and some enterprises still lack awareness of environmental protection and compliance with laws, fail to fully implement relevant laws, regulations and policy requirements of the country and Shandong Province, have relatively backward production processes, insufficient investment in environmental protection funds, and incomplete recycling systems. Shandong The province still lacks a regional recycling network established by battery manufacturers or recycled lead companies. Random disassembly often occurs, and leaked electrolyte causes harm to the environment. Shandong Province issued the "Technical Specifications for Pollution Prevention and Control in the Lead-acid Battery Industry of Shandong Province" in 2011, which played a positive role in standardizing the clean production and pollution prevention of lead-acid battery manufacturing enterprises in Shandong Province. However, this standard only targets battery manufacturers. With the substantial increase in the sales, use and recycling of lead-acid batteries in recent years, this standard can no longer meet the overall pollution prevention and control requirements of the current lead-acid battery industry in Shandong Province.

　　2. What are the main principles and characteristics of technical specifications?

　　According to the pollution characteristics of the lead-acid battery industry, follow the principle of whole-process pollution control, take the emission reduction of heavy metal pollutants as the core, and focus on pollution prevention, actively promote source reduction and substitution, highlight the control of the production process, promote the extension of environmental responsibilities of production enterprises, and standardize Recycle resources, improve the environmental risk prevention and control system, enforce cleaner production audits, and promote environmental information disclosure.

　　This technical specification puts forward pollution prevention and control requirements for the entire life cycle of lead-acid batteries, which includes the entire process of lead-acid battery design, production, sales, use, collection, transfer, storage, and regeneration. It is the first domestic standard that addresses the entire life cycle of lead-acid batteries. Periodically carry out environmental protection standards required by the system.

　　3. Main contents of "Technical Specifications for Pollution Prevention and Control throughout the Life Cycle of Lead-Acid Batteries"

　　First, specific technical requirements for pollution prevention and control in the lead-acid battery production process are proposed in terms of production enterprises, lead-acid battery production process pollution control technology, lead-acid battery production pollutant treatment technology, etc., and are stated in the "Shandong Province Lead-acid Battery Industry Pollution Prevention and Control Technology" Specification" (DB 37/T 1931-2011), the technical requirements for production process pollution control of each production process and the pollutant treatment requirements for wastewater, waste gas and solid waste of production enterprises are updated and optimized. The second is to clarify the relevant requirements for the extension of environmental responsibilities of lead-acid battery manufacturers, gradually form a recycling system with clear responsibilities, standardized and orderly supervision, and improve the comprehensive competitiveness and resource and environmental benefits of Shandong's lead-acid battery products. The third is to put forward technical requirements for the prevention and control of pollution during the sales and use of lead-acid batteries, increase the enthusiasm and standardization of sellers to participate in recycling, encourage and standardize consumers' recycling behavior, and promote the correct use and effective recycling of lead-acid batteries. The third is to standardize the technical requirements for pollution prevention and control during the collection, transfer and storage of waste lead-acid batteries. Fourth, the technical requirements for pollution prevention and control during the regeneration and treatment of waste lead-acid batteries were clarified, and effective pollution prevention and control measures were proposed for different regeneration and treatment processes.

　　4. What role will the "Technical Specifications for Pollution Prevention and Control throughout the Life Cycle of Lead-acid Batteries" play after its implementation?

　　The first is to promote the elimination of backward production capacity and improve the technical level of the industry. This standard puts forward specific production and regeneration technical requirements for lead-acid battery manufacturers and recycled lead companies. For example, products adopt ecological design, the production process adopts cadmium-free, arsenic-free processes and internalization processes, and waste lead-acid batteries adopt automatic crushing and sorting technology. Dismantling, using closed smelting, low-temperature continuous smelting, mechanized ingot casting technology for lead regeneration smelting, etc. will promote the gradual elimination of backward production capacity in the lead-acid battery industry in Shandong Province and continue to improve the technical level of lead-acid battery manufacturers and recycled lead companies. Achieve cleaner production and source pollution control.

　　The second is to standardize pollution prevention and control in the industry and improve the level of terminal treatment of pollutants. This standard sets out specific requirements for the treatment and disposal of waste gas, waste water, and solid waste for lead-acid battery manufacturers and lead recycling companies. For example, production and regeneration processes require the connection of lead dust, lead smoke, and sulfuric acid mist collection and treatment devices, and the classification of production wastewater and domestic wastewater. Collection and processing, lead-containing waste should be treated as hazardous waste in strict accordance with national standards and requirements, etc., which will promote pollution prevention and control in the lead-acid battery industry in Shandong Province, properly and effectively handle exhaust gas, waste water and solid waste, and further improve the end-of-line treatment of enterprise pollutants level.

　　The third is to improve the waste lead-acid battery recycling system to ensure environmental safety. This standard sets out requirements for the units, vehicles, facilities and specific environmental behaviors involved in the collection, sale, transfer and storage of waste lead-acid batteries. It is not only a concrete practice of the extended environmental responsibility system for producers, but also helps standardize waste lead-acid batteries in Shandong Province. Battery recycling behavior, improve the recycling system, standardize the flow of waste batteries, curb random acid dumping, truly realize pollution prevention and risk prevention and control throughout the life cycle of lead-acid batteries, and ensure environmental safety.
