【摘要】 北京市平谷区自2005年至2018年共建设农村污水处理设施96套,污水处理工艺分别有A/O工艺、A/O一体化工艺、人工湿地、MBR膜生物反应器、无动力生物净化槽、土壤渗滤工艺、MBR膜+人工湿地等,经过2018年调研,农村污水处理设施运转较好的不到20%。本文从平谷区农村实际情况出发,在深入研究国内外现行的农村污水处理工艺技术的基础上,通过现场调研和监测分析,对现有污水处理工程使用情况进行分析评述,目的在于探索适合平谷区农村污水处理的技术工艺,对现有的处理工程进行优化,对适宜的污水处理工艺进行推广。更多还原

【Abstract】 Ninety-six rural sewage treatment facilities have been constructed in Pinggu District of Beijing from 2005 to 2018. The sewage treatment processes include A/O process, A/O integrated process, constructed wetland, MBR membrane bioreactor, powerless biological purification tank, soil infiltration process, MBR membrane + constructed wetland, etc. After investigation in 2018, the rural sewage treatment facilities run better than 20%. Starting from the actual situation of rural areas in Pinggu District, on the basis of in-depth study of the current rural sewage treatment technology at home and abroad, through on-site investigation and monitoring analysis, this paper makes an analysis and comment on the use of existing sewage treatment projects, aiming at exploring the suitable technology for rural sewage treatment in Pinggu District, optimizing the existing treatment projects and optimizing the suitable sewage. The treatment process is promoted.更多还原
