摘　　要：结合分散性生活污水的水质水量特点,介绍了几种适合处理此类污水的工艺技术,同时就其自身的特点、适用性及工程经济性等方面进行了分析比较,得出净化沼气池、人工湿地、蚯蚓生态滤池、高效藻类塘技术的投资、运行费用低、管理简单方便。而膜生物反应器和一体化处理装置的投资和运行费用都较高,且需要专业技术人员管理,可应用于经济发展水平高,对出水水质要求高的地区。同时,也提出了分散性生活污水处理技术应用中尚待解决的问题,旨在为我国分散性生活污水的治理服务。In response to the characteristics of decentralized domestic sewage, several treatment technologies for decentralized domestic sewage were introduced, with the characteristics, applicability, and engineering economic analyzed and compared. The technologies including biogas purification tank, constructed wetland, viewing earthworm ecological and high rate algal pond were characterized by low investment, operating cost, and convenient management, The membrane bioreactor and integrated treatment equipment had the higher operating, cost, and the need for professional management, which could be used in the area with higher economic development and stricter effluent qualities. Meanwhile, the problems of decentralized domestic sewage treatment technologies which need to be resolved in the future were proposed for further treatment on the decentralized domestic sewage in our county.
