The research and application of the modular equipment for decentralized domestic sewage treatment based on the technologies of anaerobic-anoxic-aerobic and membrane bioreactor methods are carried out and the result shows that the technical and economic indexes at each stage of the study all meet and exceed the first class A emission standard of urban sewage treatment pollutant emission standard(GB18918-2002). The concept of decentralized treatment offers great potential for developing sustainable environmental protection and energy conservation, decentralized sewage control and management will result in significant savings in capital and operating costs for drainage networks and pumping stations especially in water-scarce areas. Decentralized wastewater treatment should be regarded as an important concept of municipal wastewater treatment and a feasible treatment program. Decentralized wastewater treatment technology has a broad development prospect in the future wastewater treatment field.
