摘要：
以某污水厂为例,介绍了水解酸化—A2/O氧化沟—纤维转盘滤池组合工艺处理城市污水的效果。该工程处理水量7万m3/d,进水COD、BOD5、SS、NH4+-N、TN、TP分别为326.2、138.8、156.8、32、63、1.6 mg/L。采用该工艺处理后,COD、BOD5、SS、NH4+-N、TN、TP的去除率分别为90.1%、93.3%、94.4%、90.0%、77.3%、75%,出水达到了《城镇污水处理厂污染物排放标准》(GB 18918—2002)一级A排放标准。该工艺具有运行费用低、处理效果好、操作方便的优点。

Abstract:
Taking an urban sewage treatment plant as example,the treatment effect of the combined process,hydrolysis acidification-A2/O oxidation ditch-fiber turntable pond technology,is introduced.The treatment capacity is 70 000 m3/d,and the influent COD,BOD5,SS,NH4+-N,TN,TP are 326.2,138.8,156.8,32,63,1.6 mg/L respectively.The operation results show that the removing rates of them are 90.1%,93.3%,94.4%,90.0%,77.3%,75%,respectively.The effluent quality meets the requirements of the first grade A criteria specified in the Pollutant Discharge Standard of Municipal Wastewater Treatment Plant(GB 18918—2002).This process has the advantage of low operation cost,good treatment effect and convenient operation.
