摘　　要：近年来,随着洗涤剂的广泛使用,废水中氮、磷的含量明显增加,引起水体富营养化加剧,因此,必须有效提高城镇污水处理厂氮和磷的去除。对多种除磷脱氮的活性污泥法,包括氧化沟工艺、A2/O工艺、UCT工艺等,进行比较与分析,结果表明,UCT工艺比较适合除磷脱氮要求较高的污水处理厂应用。With the widely using of detergents in rencet years, the content of phosphorus and nitrogen were significantly increased, and indused to water eutrophication aggravation, therefore, it＇s must improve the effective of phosphorus and nitrogen removal in municipal sewage treatment. Several activated sludge process including oxidation ditch, A^2/O and UCT to phosphorus and nitrogen removal were compared and analyzed. The results showed that UCT process was suitable for high requirements wastewater plant＇phosphorus and nitrogen removal.
