在比较国内外现有的分散式处理技术的优缺点的基础上,结合现阶段我国农村水污染现状和水污染特征,分析了如何因地制宜地选择适宜技术,重点分析了农村分散式污水处理源头分离技术的优点及必要性,同时介绍了蚯蚓生态滤池、人工湿地、地下渗滤系统和滴滤池及一体化处理设备等分散污水处理技术的适用特点,为今后在我国农村推广稳定高效的分散式污水处理设施提供必要的技术参考.%Based on the comparison of the advantages and disadvantages of the distributed processing technology in domestic and abroad, and combining with nowadays the present situation and characteristic of the water pollution in rural areas of our country, problem as how to choose the appropriate technology according to local conditions was expounded. And the advantage and necessity of the source separation of decentralized sewage treatment in rural ureas was highlighted. At the same time, the applicable features for decentralized sewage treatment, which was consisted of earthworm filter bed, constructed wetlands, subsurface infiltration system and trickling filter and the integration of processing equipment were discussed. The results may serve as an effective technical reference for promoting stable and efficient decentralized treatment facilities in the future.
