摘　　要：大同市某污水处理厂设计规模为5000 m^(3)/d,采用A/A/O+微絮凝过滤工艺运行。在厂区用地紧张、无扩建条件的前提下,结合构筑物现状对生化系统进行优化升级。通过对内部结构进行局部调整,实现了对COD、BOD_(5)、SS、NH_(3)-N、TN和TP的高效去除。运行结果表明,提标改造完成后的污水处理厂出水水质优于《城镇污水处理厂污染物排放标准》(GB 18918—2002)一级A标准,工艺运行稳定,可为类似工程提供借鉴。The design scale of a sewage treatment plant in Datong is 5000 m^(3)/d with A/A/O+micro-flocculation filtration process.On the premise of tight land in the plant area and no expansion conditions,optimization and upgrading of biochemical system were carried out in combination with the current situation of structures.Through the local adjustment of the internal structure,the efficient removal of COD,BOD_(5),SS,NH_(3)-N,TN and TP was realized.The operation results showed that the effluent quality of the sewage treatment plant after the upgrading and reconstruction was better than the first-class A standard of the Discharge standard of pollutants for municipal wastewater treatment plant(GB 18918—2002),and the process operation was stable,which could provide reference for similar projects.
