Technical Applicability for Decentralized Sewage Treatment in Rural Areas

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 areas 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.
