摘　　要：目前,我国主流的污水处理工艺分为AAO工艺、氧化沟工艺、SBR工艺及其变形工艺、曝气生物滤池工艺以及其他工艺。本文介绍了几种主流工艺的原理、特点及缺点,以期实现污水的有效处理和稳定达标排放。研究发现,AAO工艺流程简单,具有良好的脱氮除磷效果,成为我国目前最主流的处理工艺;其他工艺各有优缺点和应用场景;提高生物脱氮效率是我国市政污水处理工艺的发展趋势。At present,the mainstream sewage treatment processes in China are divided into AAO process,oxidation ditch process,SBR process and its deformation process,aerated biological filter process and other processes.This paper introduces the principles,characteristics and shortcomings of several mainstream processes in order to achieve effective sewage treatment and stable discharge up to standards.The study finds that the AAO process is simple and has good denitrification and phosphorus removal effects,and has become the most mainstream treatment process in China;other processes have their own advantages and disadvantages and application scenarios;improving the efficiency of biological denitrification is the development trend of China’s municipal wastewater treatment process.
