摘　　要：温州鹿城轻工产业园区污水处理厂原有一期工程主体工艺为Bardenpho+BAF,出水COD、NH_(3)-N、TN及TP无法稳定达到《城镇污水处理厂污染物排放标准》(GB 18918—2002)的一级A标准。在一期工程投加外部碳源、新增设备及优化运行参数基础上,提标改造工程新建高效沉淀池+反硝化深床滤池深度处理工艺,强化脱氮除磷及去除SS。连续9个月的运行数据表明,系统出水COD、NH_(3)-N、TN、TP平均值分别为21.2、0.85、9.21、0.23 mg/L,平均去除率分别为81.4%、94.2%、60.6%、88.2%,出水各项指标均达到甚至优于一级A标准。The main process of the original first phase of Wenzhou Lucheng Light Industry Park wastewater treatment plant was Bardenpho and BAF,of which,the effluent COD,NH_(3)-N,TN and TP could not stably meet the first level A criteria specified in the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant(GB 18918-2002).By adding external carbon sources,adding new equipment and optimizing operation parameters of the first phase project,the advanced treatment process of high efficiency sedimentation tank and denitrifying deep bed filter is newly built in the upgrading and reconstruction project to strengthen nitrogen,phosphorus and SS removal.The water quality of 9 consecutive months indicated that the average values of effluent COD,NH_(3)-N,TN and TP are 21.2 mg/L,0.85 mg/L,9.21 mg/L,0.23 mg/L respectively and the average removal rates are 81.4%,94.2%,60.6%,88.2%respectively.All the indexes of effluent can meet and even surpass the first level A criteria.
