我国农村生活污水分散式处理技术

Decentralized Processing Treatment Technology for the Rural Domestic Sewage in China

当前,农村污水污染已对农村地区的水体、土地等自然环境产生严重影响,为确保农村水源安全和农民身体健康,农村污水治理刻不容缓。笔者介绍了高效藻类塘技术、地下渗滤处理系统、蚯蚓生态滤池、人工湿地处理技术、膜生物反应器技术等几种分散式生活污水处理技术的原理、特点、不足及其应用现状,为农村地区污水治理提供参考。

Nowadays,rural domestic sewage has more serious effects on rural nature environment such as the water pollution and land pollution in rural area.In order to ensure the safe water in rural areas and good health condition of farmers,it is urgent to treat rural sewage.The theoretical principle,characteristic,deficiencies and applications of some decentralized sewage disposal technologies were introduced,which included the high rate algal pond,subsurface infiltration system,earthworm and ecological filter cell,constructed wetland technology and membrane bioreactor technology,so as to provide reference for treating the rural sewage.
