摘　　要：四川省眉山市城市污水处理厂(一期)提标改造工程采用了后置反硝化生物滤池工艺,将原有两级曝气生物滤池中第二级其中一半改造成反硝化生物滤池。主要介绍了该改造工程的参数、挂膜启动以及运行效果。实际运行表明,后置反硝化生物滤池具有明显的脱氮除磷效果,调试时TN最高去除率达95%,出水TN为1.3 mg/L。改造后出水水质稳定达到《城镇污水处理厂污染物排放标准》(GB 18918—2002)的一级A标准。The first phase of Meishan Municipal Wastewater Treatment Plant in Sichuan was up- graded by using post denitrification biofihers to replace half of the original biological aerated filters in the second stage. The parameters of the transformation project, the startup of film formation and the operation effect were introduced. The actual operation showed that the post denitrification biofiher had obvious effect of denitrification and phosphorus removal. The maximum removal rate of TN is as high as 95% , and the effluent TN is as low as 1.3 mg/L during commissioning. The effluent quality after transformation could reach first class A criteria specified in Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant（ GB 18918 - 2002）.
