UASB-A/O-曝气生物滤池工艺处理聚丙烯酰胺废水

UASB-A/O-Biological Aerated Filter Process Treat Acryl Amide Production Wastewater

UASB-A/O-曝气生物滤池组合工艺处理聚丙烯酰胺高浓度有机废水,设计规模为120m3/d。在进水COD、BOD、SS、NH3-N的质量浓度分别为4140、1420、238、78mg/l时,处理后出水COD、BOD、SS、NH3-N的质量浓度分别为112、17、13、11mg/l,达到污水综合排放标准(GB 8978–1996)二级标准。工程实践表明,该组合工艺具有投资少,占地面积小、运行效果稳定、运行费用低等优点。

The asylums wastewater was treated with UASB-A/O-Biological aerated filter,the quantity of wastewater is 120m3/d.When the quality concentrations of COD,BOD5,SS,NH3-N in influent are 4140,1420,238,78mg/l,the quality concentrations of COD,BOD5,SS,NH3-N in effluent are 112,17,13,11 mg/l,respectively,which reach the second-class standard of the compensative sewage discharge standard.It has been proved by practice that the combined technique has strongpoint such as low investment,little area,steady operation effect,low operation cost and recycled resources.
