摘　　要：江苏省地方标准《城镇污水处理厂污染物排放标准》(DB32/4440-2022)已于2023年3月28日起正式实施,现有城镇污水处理厂于3年后正式执行该标准。江苏某城镇污水处理目前处于接近满负荷运行状态,同时出水部分指标难以到达新标准要求,亟需提标扩容改造。通过分析污水处理厂进出水水质,确定TN为本次改造的重点控制指标。针对现有实际运行情况,结合污水厂预留用地,提出原址改造设计建议。同时结合相关工程经验提出“先南后北、先扩后改”的改造原则,保证施工过程中污水处理厂连续生产不停水,为该厂顺利完成改造工作提供技术参考。The local standard“Pollutant Discharge Standard for Urban Sewage Treatment Plants”(DB32/4440-2022)of Jiangsu Province has been officially implemented since March 28,2023,and existing urban sewage treatment plants will formally comply with this standard three years later.The urban sewage treatment plant in a certain city in Jiangsu Province is currently operating close to full capacity,and some effluent indicators are difficult to meet the requirements of the new standard.It is urgently in need of upgrading and expansion.Based on the analysis of the influent and effluent quality of the sewage treatment plant,total nitrogen(TN)has been identified as the key control indicator for this upgrade.Based on the current operational status and the reserved land for the sewage treatment plant,it was suggested to design the renovation at the existing site.Additionally,drawing from relevant engineering experiences,the principle of“expansion before renovation,and south before north”was recommended to ensure uninterrupted production during construction,providing technical references for the successful completion of the plant’s renovation work.
