摘　　要：大连市污水处理厂(二期工程)采用水解酸化/前置反硝化生物滤池处理工艺,对城市生活污水中COD、TN、氨氮、SS的去除率分别达到83.9%、61.84%、90.65%和92.3%。由于采用化学加药除磷和紫外线消毒的工艺,出水水质全面达到《城镇污水处理厂污染物排放标准》(GB18918—2002)的一级A标准。The combined process of hydrolysis acidification and pre-dcnitrification biological aerated filter was used in the second-phase project of Dalian Sewage Treatment Plant. The removal rates of COD, TN, ammonia nitrogen and SS in municipal sewage are 83.9% , 61.84%, 90.65% and 92.3% respectively. Because of using chemical phosphorus removal and ultraviolet disinfection, the effluent quality meets the first level A criteria specified in Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant （ GB 18918 - 2002）.
