摘　　要：为了解决传统活性污泥法处理生活污水存在氮、磷去除率低的问题,本文介绍了倒置A2/O脱氮除磷新工艺的原理及其特点,并采用该工艺对某小型传统活性污泥法污水处理站进行了工艺改造。结果表明,该新工艺对传统活性污泥法污水处理厂进行的改造,可以充分利用原工艺的场地、构筑物及设备,只需少量的改建投资即可达到污水站在保持较高的COD、BOD去除率的同时,出水氮、磷的含量也达到规定的排放要求。A new technological process of inverted A^2/O for nitrogen and phosphorus removal was applied to solve the problem of low nitrogen and phosphorus removal by the traditional activated sludge method for the treatment of domestic sewage. And using the process, a small- scale sewage treatment station with traditional activated sewage process was reformed technologically. It is shown that this reform can fully utilize the original spots, structures and equipment; less investment for rebuilding enables the sewage station to keep higher removal rate of COD and BOD; meanwhile, the effluent nitrogen and phosphorus content can reach the discharging requirements stipulated.
