摘　　要：针对污水处理厂尾水作为景观补水普遍存在氮、磷等污染物超标的问题,采用"预处理系统+横流式复合生物滤池"工艺,对污水处理厂尾水进行深度强化处理。运行结果表明,该工艺对污水处理厂尾水净化效果良好,对COD、BOD5、SS、TN、NH3-N和TP的平均去除率分别为47.2%、73.7%、73.1%、30.9%、44.6%和32.6%,出水水质(除TP外)均达到《城镇污水处理厂污染物排放标准》(GB 18918—2002)的一级A标准。To solve the problems of high contentions of nutrient （ especially nitrogen and phosphorus） when using effluent of WWTP as landscape water, the pretreatment system and cross-flow hybrid biofilter were combined for tertiary treatment of the effluent from WWTP. The results showed that the combined process performed well in tertiary treatment of the effluent from WWTP. The average removal rates of COD, BODs, SS, TN, NH3- N and TP were 47.2% , 73.7% , 73. 1% , 30.9% , 44.6% and 32.6%, respectively. The effluent quality （ except for TP） of the cross-flow hybrid biofiher could meet the first level A criteria specified in the Discharge Standard of Pollutants for Municipal Wastewater Treat- merit Plant （ GB 18918 - 2002）.
