摘要
无锡市城北污水处理厂升级改造工程设计规模15万m3/d,采用强化二级生物脱氮除磷以及增加三级盘片式微过滤工艺进行改造,出水达到《城镇污水处理厂污染物排放标准》(GB18918—2002)中的一级A排放标准。介绍了升级改造工程处理工艺选择、工程设计参数、设备配置情况等,总结分析了升级改造工艺设计的技术特点和要求。
The design capacity of the upgrading reconstruction project of Chengbei Wastewater Treatment Plant in Wuxi was 150 000 m^3/d. In the project, the enhanced secondary biological nitrogen and phosphorus removal process and tertiary plate microfiltration process were employed, and the effluent met the first class A standards specified in Discharge standard of pollutants for municipal wastewater treatment plant （GB 18918--2002）. The process scheme, design parameters, equipments configuration were discussed, and the technical features and requirement of this upgrading reconstruction design were also summarized and analyzed.
