摘要

十堰市神定河污水处理厂原处理规模为16.5万m~3/d,主体工艺采用"AO-二沉池"与"AAO-MBR"并行工艺,出水混合后,执行城镇污水处理厂污染物排放标准一级B标准。该厂通过将原废弃二沉池改建为MBR池,不增加占地,处理能力扩大到18万m~3/d;通过CAS-MBR复合工艺改造,出水水质优于一级A标准。
        Before upgrading reconstruction,the capacity of Shendinghe WWTP in Shiyan city was 165,000 m~3/d and the main process of the WWTP was a combination of traditional AO and AAO — MBR.The effluent quality could meet the "I-B" National Discharge Standard in China.After upgrading reconstruction,the capacity was increased to 180,000 m~3/d by modifying the discarded sedimentation tanks into membrane bio-reactors,and the effluent quality was improved to "I — A" National Discharge Standard by adopting combined process of CAS — MBR.
