摘　　要：选择长江三角洲地区有一定代表性的乡村家庭,开展了厌氧池-多级布水模块化人工湿地原位处理源分离后的废水的实例研究,旨在掌握乡村家庭源分离后废水的水质特征,并通过厌氧池-多级布水模块化人工湿地,重点解决乡村家庭源分离后的废水原位净化达标排放问题。结果表明,耗氧有机物(以COD计)、BOD5、LAS(linear alkylbenzene sulfonates)是洗涤废水、灰水中的主要污染物质;季节变化、进水浓度对厌氧池-多级布水模块化人工湿地处理源分离后的废水中的耗氧有机物、LAS影响不显著,但季节变化对粪大肠菌群影响显著。总体上,2户农户的设施出水均符合《农田灌溉水质标准》(GB 5084-2005)水作作物的相关规定。In this study,two representative rural households in the Yangtze River Delta were taken as test sites,then a case study of on-site treatment of wastewater after source separation by an anaerobic tank-modular constructed wetland with multi-level water distribution(AT-MCW)was conducted.The aims of this study were following:grasping the water quality characteristics of rural household wastewater after source separation,and solving the problem of up-to-standard discharge of wastewater after source separation from rural households through on-site treatment with AT-MCW.The results showed that oxygen-consuming organic matter(in COD),BOD5 and LAS(linear alkylbenzene sulfonates)were the main pollutants in washing wastewater and grey water;Seasonal changes and influent concentration had no significant effects on the treatment of oxygen-consuming organic matter and LAS in the two types of wastewater by AT-MCW,but seasonal changes had significant effects on fecal coliform;In general,the effluents from the facilities of AT-MCW in two rural household could meet the standard limit of water crop types in the Standards for Irrigation Water Quality(GB 5084-2005).
