《GB/T 40662-2021废铅蓄电池再生处理技术规范》由TC297（全国电工电子产品与系统的环境标准化技术委员会）归口，主管部门为国家标准化管理委员会。
Introduction
Analysis of the core content of the standard
This specification systematically constructs the technical system for the recycling and treatment of waste lead-acid batteries for the first time, clarifies the requirements for 23 key equipment such as automatic crushing and sorting equipment, and stipulates 12 hard indicators such as the comprehensive lead recovery rate of ≥98%.
Comparison of key technologies
| Process type | Direct recovery rate | Energy consumption standard | Pollution risk |
|---|---|---|---|
| Pyrometallurgy | 99.2% | ≤125kgce/t | SO₂ emission control |
| Hydrometallurgy | 98.5% | ≤85kgce/t | Difficulty of wastewater treatment |
Key points of pollution control
Take a recycled lead enterprise in Jiangsu as an example. class=instrument>Ion membrane reverse osmosis system achieves 100% recycling of waste electrolyte, and the concentration of lead dust emissions is stably controlled at 0.8mg/m³ (national standard limit 1.0mg/m³).
Implementation suggestions
- Give priority to the use of closed smelting equipment recommended in the "Guidelines for Industrial Structure Adjustment"
- Establish a heavy metal online monitoring system, and keep data for ≥5 years
- Carry out occupational health examinations every quarter, and protective equipment complies with GB/T11651
