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.
