| 摘 要： | 研究了不同流向对曝气生物滤池的影响情况,结果表明,上流式曝气生物滤池挂膜时间要略小于下流式曝气生物滤池。从CODCr,LAS主要污染物指标的去除效果上看,上流式要优于下流式曝气生物滤池,且所需气水体积比小,承受水力负荷大,沿水流方向相同滤层高度的去除率高。两种流向的曝气生物滤池,对洗浴废水处理后各项指标符合城市杂用水水质标准GB/T1890-2002。

| Abstract: | The effect of different flows on biological aerated filter(BAF) was investigated by experiment.The result showed,the form-film time of up-flow BAF was shorter than that of down-flow BAF.Obtained results of CODCr and LAS removal efficiency,indicated that up-flow BAF was superior than down-flow BAF.Compared with the performance of down-flow BAF,up-flow BAF need smaller gas-water ratio and could have higher hydraulic loading.Higher pollutants removal rate could also be achieved in the same media height along the flow direction.The efflvent quality of both kinds of BAF could meet the standard of the water treatment standards GB/T1890-2002. |
