摘要
为量化铅酸蓄电池从原料开采到综合回收利用的全生命周期过程产生的水足迹影响,基于生命周期评价理论的水足迹分析方法对周期过程产生的水足迹进行综合分析。使用SimaPro 8.4软件对铅酸蓄电池制备、运输、使用、所消耗电力的生产和废旧电池回收利用过程进行水足迹影响分析,结果表明铅酸蓄电池生产制备和消耗电力的生产是两个最主要的水足迹影响过程,电池生产制备对水体富营养化、致癌性影响、淡水生态毒性和水稀缺影响显著,电力生产对酸性化和非致癌性影响有显著贡献。铜、铬、排入水体的磷酸盐和排入大气的二氧化硫等关键物质也主要来自于这两个过程。优化这两个主要过程有助于有效地减少铅酸蓄电池全生产链条的水足迹。
To quantify the water footprint impacts throughout the whole life cycle of lead-acid batteries from raw materials extraction to comprehensive recycling and reuse,a water footprint analysis based on life cycle assessment method was used to comprehensively analyze the water footprint generated by life cycle.SimaPro 8.4 software was used to analyze the water footprint impacts on lead-acid battery preparation,transportation,use,production of consumed electricity,and waste battery recycling processes.Results showed that lead-acid battery production and generation of consumed electricity were the two most important processes in water footprint analysis,among which the former had significant impact on aquatic eutrophication,carcinogens,freshwater ecotoxicity and water scarcity categories,while the latter had considerable contributions to acidification and non-carcinogens.In addition,key substances such as copper,chromium,phosphates discharged into water and sulfur dioxide to the atmosphere were mainly derived from these two processes.Optimizing these two main processes would help to reduce the water footprint of the lead-acid battery production chain effectively.
