Scope

Main technical content: The main content includes management requirements, technical requirements, and process flow and treatment methods. The management requirements specify that the lead-acid batteries recycled by the enterprise should have complete collection and processing records, and appropriate production processes and equipment should be used for crushing, sorting, melting, dust removal, desulfurization, and purification. During the processing of lead-acid batteries, the discharge of wastewater, waste gas, noise, and solid waste should comply with the requirements of GB 8978, GB 16297, and the "Management Measures for the Transfer of Hazardous Waste" issued by the National Environmental Protection Administration. The recycling and processing of lead-acid batteries should comply with the requirements of GBZ 1, GBZ 2.1, GBZ 2.2, and GB 13746. The technical indicators refer to the "HJ 510-2009 Cleaner Production Standard for Lead Recovery from Waste Lead-Acid Batteries", which specifies resource and energy utilization indicators, pollutant generation indicators, and waste recycling indicators. According to the calculation method of the indicators, the necessary data is collected and analyzed. Then, the results are evaluated against the benchmark values of the indicator system, which can be used as a reference for the enterprise's environmental impact assessment and pollution discharge permits. The process flow of recycling lead from lead-acid batteries by crushing includes waste battery recycling, punching, acid discharge, acid recovery, crushing, lead-plastic separation, lead block melting, desulfurization and purification, etc. The requirements of each processing link are specified, which can improve the processing efficiency of battery recycling and protect the environment.
