农村生活污水处理技术模式与进展

Modes and Developments of Domestic Wastewate Treatment Technology in Rural Area

农村生活污水造成的环境污染问题亟待解决。文中分析了农村生活污水的特点、处理现状和存在的主要问题,探讨了农村生活污水处理的集中式和分散式两种主要处理模式。由于我国农村生活污水以分散式为主,而这方面的研究较少,文中就分散式生活污水处理模式在国内外的研究现状进行了探讨,建议充分结合当地条件和处理要求,灵活的组合生物-生态污水处理技术,尽量使污水处理技术实现低能耗、优质化、资源化,实现农村水污染防治工作的良性发展,保护和改善当地的生态环境。

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.
