高浓度农村生活污水处理技术研究

随着城镇化的发展和农村经济水平的提高，农村生活污水已经成为影响中国农村水环境质量的主要因素之一。农村环境的恶化直接威胁农民群众的身体健康，阻碍农村经济发展，因此针对水质特点选择合适的工艺处理农村生活污水至关重要。针对中国部分农村生活污水浓度高的特征，介绍了适宜于中国农村的生活污水净化沼气池技术、生物滤池技术、高效藻类塘处理技术、生物转盘技术、吸附生物降解技术、SBR、人工湿地技术等的技术要点、优缺点、适用范围等，为中国农村地区生活污水处理提供参考。

Review on Treatment Technologies for High Concentration Rural Domestic Sewage

With the development of urbanization and the improvement of rural economy, the rural domestic sewage has be come one of the main factors affecting the quality of water environment in rural China. The deterioration of rural environment di rectly threatens the residents＇ health, hindering the development of rural economy, so it is very important to choose the appropriate technology for rural sewage treatment according to the water quality characteristics. According to the characteristics of some high concentration rural domestic sewage, the paper introduces the technical points, advantages and disadvantages, applicable scope of the domestic sewage purification biogas digester technology, biological aerated filter process, high rate algal pond treatment tech nology, rotating biological contactor technology, adsorption biodegradation technology. SBR technology, and constructed wetland technology. This paper provides reference for the domestic sewage treatment in the rural areas of china.
