Abstract: The research progress of biological removal of nitrogen and phosphorus for treating municipal wastewater is reviewed. Three advanced processes of biological nutrient removal are emphasized：combined ANAMMOX-SHARON process，aerobic granular sludge process and reversed Anaerobic/Anoxic/oxic (A2/O) process .The advantages and disadvantages of various processes are compared. Consequently，applying denitrifying phosphorus removal bacteria to the reversed A2/O process is considered to be an important trend of simultaneous removal of nitrogen and phosphorus

摘要： 评述了近年来城市污水生物脱氮除磷技术的研究进展，重点介绍了生物处理的新方法：ANAMMOX–SHARON组合法、好氧同步脱氮除磷法和倒置A2/O法，并比较了各种工艺的优缺点。指出反硝化聚磷技术在倒置A2/O工艺中的应用将成为城市污水同步脱氮除磷研究的一个重要发展方向。
