摘　　要：集中收集和跨区域转运制度确立了我国铅酸蓄电池生产者责任延伸制(EPR)的实施路径。在危险废物管理框架下,集中收集和跨区域转运改变了废铅酸蓄电池的物质流过程,与之相关的资源环境效应变化也成为当前的重要研究课题。以贵州省为例,基于实地调研和系统模拟,采用物质流分析和生命周期评价方法分析了废铅酸蓄电池的产生特征、物质流过程和碳减排效益。结果表明,在集中收集与跨区域转运制度实施前,83.3%的废铅酸蓄电池进入再生铅企业,16.7%流入非正规处理企业,回收处理1 t废铅酸蓄电池的碳减排效益为923.1 kgCO_(2)eq。开展情景分析发现,相对于无政策驱动的基准情景,集中收集和跨区域转运优化情景均能提升废铅酸蓄电池进入正规回收处理企业的比例,且碳减排效益分别提高到994.44和953.53 kgCO_(2)eq·t-1。这表明,基于EPR政策驱动的系统情景具有环境正效应,可作为当前废铅酸蓄电池回收处理系统完善和政策优化的方向。The centralized collection and cross-regional transport system establishes the implementation path of the extended producer responsibility system(EPR)of lead-acid battery in China.Under the framework of hazardous waste management,centralized collection and cross-regional transfer have changed the material flow of spent lead-acid batteries,and the related changes in resource and environmental effects have also become an important research topic.Take Guizhou Province as an example,material flow analysis and life cycle assessment method were used to analyze the generation characteristics,material flow process and carbon emission reduction benefits of spent lead-acid batteries based on field investigation and system simulation.The results showed that before the implementation of the centralized collection and cross-regional transport system,83.3%of the waste lead-acid batteries entered the lead-recycling enterprises,and 16.7%entered the informal processing enterprises.The carbon reduction benefit of spent lead-acid batteries recycling was 923.1 kgCO_(2)eq/t.Through the scenario analysis,it was found that compared with the baseline system without policy driving force,the centralized collection and cross-regional transfer optimization scenarios could significantly increase the proportion of spent lead-acid batteries entering formal recycling enterprises,and the carbon reduction benefits were increased to 994.44 kgCO_(2)eq/t and 953.53 kgCO_(2)eq/t,indicating that the system scenario driven by the EPR policy had a positive environmental effect,and could be used as the direction for the improvement and policy optimization of the current spent lead-acid battery recycling system.
