摘　　要：利用ebalance ECER软件,对地下土壤渗滤系统进行生命周期评价,对比分析其生命周期各个过程中非生物资源耗竭、酸化、富营养化、全球变暖和固体废物等主要环境影响类型,并确定了主要的环境影响类型和造成环境影响的关键环节。结果表明:富营养化和全球变暖是地下土壤渗滤系统环境影响的主要类型,分别占地下土壤渗滤系统环境影响总值的75.9%和13.5%;地下土壤渗滤系统环境影响大小的顺序依次为富营养化、全球变暖、酸化、固体废物和非生物资源耗竭。通过对地下土壤渗滤系统的研究,可为农村污水处理工艺的生命周期评价提供数据支持,并推动农村生活污水处理的可持续发展。This paper presents Life Cycle Assessment(LCA)of the subsurface soil infiltration system(SSIS)using ebalance ECER and evaluates the environmental impact potentials during each process of the system.The paper analyzes and compares the main environmental impact types such as Abiotic Depletion(ADP),Acidification Potential(AP),Eutrophication Potential(EP),Global Warming Potential(GWP)and solid waste in each process of life cycle,and identifies the main types of environmental impacts and the key links that cause the environmental impacts.The results show that compared to other environmental impact potentials,the EP and GWP potentials are the main influenced types,which account for 75.9%and 13.5%respectively.Regarding the extent of environmental impacts of subsurface soil infiltration system,these parameters can be ordered as EP,GWP,AP,Solid Waste and ADP.Compared to other stages,septic-tank exerts the most destructive influence on the environment with the contribution proportion of 83%.Due to the consumption of resources and transport capacity,the highest ADP,AP and GWP values are generated during septic-tank stage.Sewage collection stage has the highest Waste Solids value.The paper studies the LCA of SIS,which provides data for LCA of rural sewage treatment technology and promotes the sustainable development of rural sewage treatment.
