摘　　要：山东某10×10~4m^3/d规模污水处理厂,原设计出水水质执行一级B标准。进水水质严重偏离设计水质,导致出水COD及TN达标困难。随着环保要求的提高,需升级改造至出水水质达到《城镇污水处理厂污染物排放标准》(GB 18918—2002)一级A标准。经过中试论证后,最终采用"反硝化深床滤池+电磁催化臭氧氧化"深度处理工艺。升级改造工程完成后,出水各项指标均达到一级A排放标准。The original design effluent of a WWTP with a capacity of 10 ×10^4m^3/d in Shandong enforced the first level B criteria specified in the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant （ GB 18918 - 2002 ）. The influent quality was seriously deviated from the deign quality, which caused that the effluent COD and TN could not meet the discharge standard. With the improvement of environmental requirements, it was urgent to upgrade the treatment process to meet the first level A criteria. Denitrification deep bed filter and electromagnetic catalytic ozonation were used as advanced treatment process after the pilot-test demonstration. After the completion of the upgrading project, the effluent quality could meet the first level A criteria.
