摘　　要：某工业园区污水处理厂设计规模为3.0×10^(4)m^(3)/d,采用水解酸化池+改良Carrousel氧化沟+高效沉淀池+活性砂滤池+臭氧接触氧化池工艺,出水水质执行《城镇污水处理厂污染物排放标准》(GB 18918—2002)的一级A标准。按照当地相关部门要求,部分出水指标需要提升至地表Ⅴ类标准。基于工程现状条件,对Carrousel氧化沟的曝气及推流方式进行改造,并增设事故池和以“臭氧催化氧化+生物活性炭滤池”为主体的深度处理工艺,同时优化外碳源投加。改造工程投运后,运行效果稳定,出水指标均满足设计要求。改造工程的投资成本为2607.3元/m^(3),改造后运行成本为1.28元/m^(3),因改造增加的运行成本为0.455元/m^(3)。The design capability of a wastewater treatment plant(WWTP)in an industrial park is3.0×10^(4)m^(3)/d,which uses the combined process of hydrolysis acidification tank,improved Carrousel oxidation ditch,high efficiency sedimentation tank,active sand filter,and ozone contact oxidation tank.The effluent is in accordance with the first level A criteria specified in the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant(GB 18918-2002).According to the requirements of the local authorities,some of the effluent indicators need to be upgraded to the level Ⅴ surface water quality standard.Based on the current conditions,the aeration and pushing modes of the Carrousel oxidation ditch were modified,and the accident pool and the advanced treatment process of ozone catalytic oxidation and biological activated carbon filter were added.Meanwhile,the carbon source supplement was optimized.After the completion of the project,the operation effect of the system was stable,and the effluent indicators met the design requirements.The retrofitting project construction investment was about 2607.3 yuan/m^(3),and the unit operation cost after the retrofitting was 1.28 yuan/m^(3),while the operation cost was increased by 0.455 yuan/m^(3) on account of the retrofitting.
