摘　　要：贵阳市中心城区某大型污水处理厂设计规模为50000m^(3)/d。采用曝气沉砂池+倒置AAO+二沉池+高效沉淀池/砂滤池的工艺。运行近三年以来,出水水质稳定达到设计标准。其中,实际平均出水COD为7.1 mg/L,NH_(3)-N为0.07 mg/L,TN为6.08 mg/L,TP为0.06 mg/L。该工艺对优先脱氮的污水具有较好的处理能力,为高TN生活污水处理提供了较好的工程实践经验。The design scale of a large-scale sewage treatment plant in the downtown area of Guiyang is 50000 m^(3)/d.The process of aerated grit chamber+inverted AAO+secondary sedimentation tank+high efficiency sedimentation tank/sand filter is adopted.After nearly three years of operation,the effluent quality has steadily reached the design standard.The average effluent COD,NH_(3)-N,TN and TP were 7.1 mg/L,0.07mg/L,6.08 mg/L and 0.06 mg/L,respectively.The process has excellent treatment capacity for wastewater with priority denitrification,and provides successful engineering practice experience for high concentration of TN domestic sewage treatment.
