摘要
采用两级曝气生物滤池处理含工业废水的城市污水.结果表明:在水温26.7～29.5℃,气/水比6∶1,进水CODcr浓度为260～600mg/L,NH3浓度为52～90mg/L、SS浓度为60～90mg/L、滤速为2.2m/h条件下,系统取得了良好的处理效果,其CODcr、NH3、SS的平均去除效率分别达到80.2%、97.8%、95.4%、出水CODcr、NH3、SS浓度满足污水综合排放要求.
This paper focused on the removal performance of the municipal wastewater treatment with the Biological Aerated Filter(BAF).The results showed that at the condition of the air/water ration of 6∶1,the water temperature of 26.7～29.5℃,the influent COD_ cr concentration of 260～600mg/L,the influent NH_3 concentration of 52～90mg/L,the filtration velocity of 2.2m/h,removal efficiencies of COD_ cr,NH_3,and SS reached 80.2%,97.8%,95.4% respectively.The treated effluent meets the National Wastewater Integrated Discharge Standard.
