摘　　要：针对城市高污染水体的特点,建成了粉煤灰基质滤料生物过滤与复合水生植物滤床组合处理系统。生物过滤在有机物和氨氮的去除方面起主要作用,磷则主要是通过人工湿地去除。运行结果表明,组合工艺出水COD、TP、NH3-N、TN平均浓度分别为16.35 mg/L、0.08 mg/L、2.68 mg/L、15.63 mg/L,均满足《城市污水再生利用——城市杂用水水质》(GB/T18920-2002)标准要求。Based on the characteristics of high polluted urban water,a treatment system was constructed by combining fly ash biofilter and complex aquatic plant filter bed.Biofilter played an important role in organic pollutants and ammonia removal,while phosphorus was mostly removed by artificial wetland.The operation results show that the average concentrations of COD,TP,NH3-N and TN in the effluent were 16.35mg/L,0.08mg/L,2.68mg/L and 15.63mg/L,respectively.The effluent quality indexes can meet the requirements of Water Quality Standard for Urban Miscellaneous Water Consumption（GB/T18920-2002）.
