摘　　要：四川省某城镇污水处理厂出水水质原来执行《城镇污水处理厂污染物排放标准》(GB 18918—2002)的一级B标准,随着城镇污水排放要求的提高,提标改造势在必行。该污水处理厂原采用“格栅井+调节池+水解酸化池+接触氧化池+二沉池+紫外线消毒”工艺,结合实际出水水质数据中总氮超标的特点,在原二沉池后、紫外线消毒渠之前增加“高效沉淀池+反硝化滤池”组合。项目出水满足《城镇污水处理厂污染物排放标准》(GB 18918—2002)的一级A标准,可为同类型城镇污水处理厂提标改造提供设计参考。The effluent quality of a certain urban sewage treatment plant in Sichuan province used to comply with the first level B standard of the Pollutant Discharge Standards for Urban Sewage Treatment Plants (GB 18918—2002),with the increasing requirements for urban sewage discharge,it is necessary to raise the standard and make improvements.The sewage treatment plant originally used the process of “grid well + regulating tank + hydrolysis acidification tank + contact oxidation tank + secondary sedimentation tank + ultraviolet disinfection”,combined with the characteristic of total nitrogen exceeding the standard in actual effluent water quality data,a combination of “high-efficiency sedimentation tank +denitrification filter” was added after the original secondary sedimentation tank and before the ultraviolet disinfection channel.The effluent of the project meets the first level A standard of the Pollutant Discharge Standards for Urban Sewage Treatment Plants (GB 18918—2002),which can provide design reference for the upgrading and renovation of similar urban sewage treatment plants.
