A^(2)/O-MBR一体化污水处理设施处理农村生活污水

Treatment of rural domestic sewage by A^(2)/O-MBR integrated equipment

江苏某镇水环境综合治理工程中,为了改善农村水环境,该镇8个污水站采用A^(2)/O-MBR工艺一体化污水处理设备进行处理。工程运行结果表明,污水站出水的COD、BOD5、SS、NH3-N、TN和TP的平均去除率分别为90.0%、98.9%、99.9%、99.7%、78.6%、74.3%,出水水质达到DB 32/3462—2020《农村生活污水处理设施水污染物排放标准》一级A标准。介绍了该工程的工艺流程、设计参数、设备选型、处理效果及技术经济分析。

In order to improve the rural water environment of a town in Jiangsu province,a comprehensive treatment project was constructed,and A^(2)/O-MBR integrated equipments were adopted in 8 rural domestic sewage treatment stations.The operation results of the project showed that,the average removal rates of CODCr,BOD5,SS,NH3-N,TN and TP in the effluent water of those stations were 90.0%,98.9%,99.9%,99.7%,78.6%,74.3%respec-tively,the effluent water quality met the requirement of level A grade 1 in DB 32/3462—2020 Discharge standard of water pollutants for rural domestic sewage treatment facilities.The process flow,design parameters,equipment type-selection,treatment effect and technological and economic analysis of the said project were introduced.
