Modes and Developments of Domestic Wastewate Treatment Technology in Rural Area

The problem of environmental pollution caused by sewage in rural areas need to be addressed. This paper analyzed the characteristics, current situation and main problems of rural sewage treatment. There were centralized processing mode and decentralized processing mode. Because rural sewage was mainly distributed and was less studied in the decentralized processing mode, this paper discussed the research status of decentralized processing mode of rural sewage treatment. The recommendations fully integrated local conditions and treatment requirements, constituted flexibly biological-ecological wastewater treatment technology, kept the sewage treatment technology to achieve low-power, high-quality and resources. In a world, it was to achieve the sound development of the rural water pollution control work, and to protect and improve the local ecological environment.
