高效沉淀池与深床滤池联合处理工艺在某污水处理厂的调试及试运行

Commissioning And Trial Operation of High-efficiency Sedimentation Tank And Deep Bed Filter Combined Treatment Process In A Sewage Treatment Plant

介绍了“高效沉淀池+深床滤池”联合处理工艺的调试与运行情况,该组合工艺具有脱氮除磷及去除SS的作用。实际运行结果表明,该组合工艺运行稳定,出水各项指标均达到要求的一级A排放标准。其中,TP、SS和TN平均进水浓度分别为1.53mg/L、22.4mg/L和9.4mg/L,平均出水浓度分别为0.25mg/L、6.18mg/L和6.71mg/L,去除率分别为83.2%、71%,25.5%。表明该组合工艺对TP、SS有较好的去除效果,对TN的去除效果一般。

The paper introduces debugging and operation of combined treatment process of“high efficiency sedimentation tank+deep bed filter”,which has functions of nitrogen and phosphorus removal and SS removal.Actual operation results show the combined process is stable and effluent indicators have reached required level A discharge standard.Among them,average influent concentrations of TP,SS and TN were 1.53 mg/L,22.4 mg/L and 9.4 mg/L,and average effluent concentrations were 0.25 mg/L,6.18 mg/L and 6.71 mg/L,with removal rates of 83.2%,71%and 25.5%respectively.It shows combined process has good removal effect on TP and SS,and TN removal effect is average.
