摘　　要：分析原工艺及原有设施情况,并详述了主要构筑物。经过原工艺处理后,出水水质只能达到《太湖地区城镇污水处理厂及重点工业行业主要水污染物排放限值》(DB 32/1072—2007)和《城镇污水处理厂污染物排放标准》(GB 18918—2002)的一级A标准,其中TN小于等于15 mg/L,而现在要求TN小于等于12 mg/L(水温大于12℃),所以本次提标改造工程增加了反硝化滤池,运行结果表明,采用“厌氧+缺氧+好氧+反硝化+混凝沉淀+滤布滤池”组合工艺即提标改造后的新工艺处理后,出水达到DB 32∕1072—2018排放要求,增加的处理成本为0.71元/t水。The original process and facilities were analyzed,and the main structures were described in de⁃tail.After the original process treatment,the effluent quality could only reach the first-class A standard in the Discharge standard of main water pollutants for municipal wastewater treatmentplant&key industries of Taihu area(DB 32/1072—2007)and the Discharge standard of pollutants for municipal wastewater treatment plant(GB 18918—2002),where TN was less than or equal to 15 mg/L.And now TN was required to be less than or equal to 12 mg/L(water temperature was greater than 12℃),so the denitrification filter was added in this upgrading project.The operation results showed that after the combination process of"anaerobic+hypoxia+aerobic+denitrifica⁃tion+coagulation precipitation+filter cloth filter"was adopted,that was after the upgrading of the new process,the effluent met the discharge requirements of DB 32/1072—2018,and the increased treatment cost was 0.71 yuan/t water.
