摘　　要：新疆某污水处理厂,一期采用氧化沟工艺,二期采用水解+五段Bardenpho工艺+二沉池+高密度沉淀池+微絮凝滤池+消毒工艺,出水执行一级A标准。稳定运行阶段平均出水COD为19.67 mg/L,NH_(4)^(+)-N、TN、TP、SS平均出水质量浓度分别为1.39、5.00、0.22、5.25 mg/L,均优于一级A标准,无超标现象出现。可为该地区其他城镇污水处理厂提标改扩工程提供借鉴和参考。In a sewage treatment plant in Xinjiang,the main process of the first stage is the oxidation ditch process.The second stage is hydrolysis+five-stage Bardenpho process+secondary sedimentation tank+high-density sedimentation tank+micro-flocculation filter+disinfection process.The effluent carries out the first-class A standard.In the stable operation phase,the average mass concentrations of COD,NH_(4)^(+)-N,TN,TP and SS in the effluent are 19.67 mg/L,1.39 mg/L,5.00 mg/L,0.22 mg/L and 5.25 mg/L,respectively,which are all better than the first-class A standard,and there is no exceeding the standard.It can provide a reference for upgrading and rebuilding other urban sewage treatment plants in this area.
