节约用水及污水处理在我国和国际上都逐步建立起了完善的方法和制度,在我国城市大都有配套的污水处理厂,但农村污染仍然严重。现在农村污水处理主要使用的方法有活性污泥法、化粪池、生物膜法等,但都具有一定的局限性。最新研究并投入使用的小型多功能净化槽,使用了平推流厌氧和全混流好氧生物反应器技术、生物膜滤床技术、空间上的一体化技术、回流技术等高科技手段,是一种非常适合农村的污水处理方法。
Water conservation and sewage treatment have gradually established sound methods and systems in our country and in the world. Most cities in our country have supporting sewage treatment plants, but the pollution in rural areas is still serious. Now the main methods used in rural sewage treatment are activated sludge method, septic tanks, biofilm method, but all have some limitations. The latest research and put into use a small multi-purpose purification tank, using a push-flow anaerobic and mixed flow aerobic bioreactor technology, biofilm filter bed technology, spatial integration technology, high-tech means such as reflow technology, is A very suitable sewage treatment in rural areas.
