摘　　要：城镇污水处理厂排水已成为流域氮、磷的一大污染源，而氨氮和总氮的达标排放成为城镇污水处理厂提标改造的重点。利用SBR池／悬浮生物滤池组合工艺对太湖流域某城镇污水处理厂出水氨氮和总氮浓度的达标排放进行了中试，取得了很好的效果。在进水NH3-N为19．6—55．7mg／L、TN为26．9-79．9mg／L的条件下，处理后出水NH3-N和TN分别在8、20mg／L以下，达到了《城镇污水处理厂污染物排放标准》（GB18918-2002）的一级B排放标准。The drainage of municipal wastewater treatment plants has become one of the major ni- trogen and phosphorus pollution sources in basins. The standard discharge of ammonia nitrogen and total nitrogen has become the key of upgrading and reconstruction of municipal wastewater treatment plants. The pilot-scale experiment on standard discharge of ammonia nitrogen and total nitrogen from a municipal wastewater treatment plant in the Taihu Lake basin was carried out using the combined process of SBR tank and suspended biological filter, and a good result was achieved. When the influent concentrations of NH3 - N and TN were 19.6 - 55.7 mg/L and 26.9 - 79.9 mg/L respectively, the corresponding effluent concentrations were less than 8 mg/L and 20 mg/L, meeting the first level B criteria specified in the D/s- charge Standard of Pollutants for Municipal Wastewater Treatment Plant （GB 18918 -2002 ）.
