农村生活污水处理技术研究进展

我国农村人口数量大并且分散造成了农村生活污水随意排放。农村生活污水的乱排既不利于环境卫生,又给居民的身体健康带来危害。结合当前农村生活污水的特征,基于农村实际情况和污水处理现状,概述了农村生活污水收集系统、化粪池、人工湿地、地埋式污水处理系统、厌氧沼气池技术、地下土壤渗滤、生物滤池、活性污泥法等处理方法,为农村生活污水处理技术选取提供参考。

China's rural population is large and scattered,resulting in the random discharge of rural domestic sewage.The random discharge of rural domestic sewage is not conducive to environmental sanitation,but also harm to the health of residents.Combined with the characteristics of rural domestic sewage,based on the actual situation and the status of sewage treatment in rural areas,the rural domestic sewage collection system,septic tank,constructed wetland,buried sewage treatment system,anaerobic biogas digester technology,underground soil infiltration,biological filter,activated sludge process and other rural sewage treatment methods were systematically summarized,which provides a reference for the selection of rural domestic sewage treatment technology.
