摘　　要：为进一步做好中心城区水环境治理,全面消除黑臭水体,某市新建准地表Ⅳ类水污水处理厂,采用三级生物滤池工艺。实际运行表明,出水CODCr、NH3-N、TN、TP均值分别为19.17 mg/L、0.19 mg/L、8.31 mg/L、0.16 mg/L,去除率均值分别为94.1%、99.4%、76.3%、95.5%,稳定达到准地表Ⅳ类水标准。三级生物滤池具有出水水质优、占地面积小、运行成本低等优势,可为准地表Ⅳ类水污水处理厂新建工程提供借鉴。In order to further improve the water environment in the central urban area and eliminate the black and odorous water, a new quasi surface class IV water and sewage treatment plant was built in a city. The combined process of Intermediate nitrification three-stage biofilter was adopted. The actual operation shows that the average values of CODCr, NH3-N, TN and TP in the effluent are 19.17 mg/L, 0.19 mg/L, 8.31 mg/L and 0.16 mg/L respectively, and the average removal rates are 94.1 %, 99.4 %, 76.3 % and 95.5 % respectively, reaching the standard of quasi surface class IV water. The three-stage biological filter with nitrification has the advantages of excellent water quality, small floor area and low operating cost, which can provide reference for the new construction of quasi surface class IV water sewage treatment plant.
