摘要
合肥某污水处理厂设计处理能力20×104m3/d,分两期各10×104m3/d建设。其中,一期仅采用A2/O氧化沟工艺,二期建设时增加微絮凝过滤深度处理工艺并对一期氧化沟进行改造。经过一年多的运行,出水稳定达到GB18918-2002城镇污水处理厂污染物排放标准中一级A标准。系统运行费用为0.320元/m3。
A sewage treatment plant of designed treatment capacity is 20×104m3/d in Hefei,each of 10×104m3/d built in two phases.In the first phase using A2/O oxidation ditch process only,increasing micro-flocculation filtering advanced treatment process in the second construct phase and modifying the oxidation ditch of the first phase.After the operation for more than a year,the effluent can consistently achieve the first-order standard A of pollutant discharge standard of urban sewage treatment plant（GB 18918-2002）.The operating costs 0.320 yuan per ton of water.
