| 摘 要： | 通过动态模拟试验,考察两种运行方式对曝气生物滤池的影响。试验结果表明,上流式曝气生物滤池的挂膜时间略少于下流式曝气生物滤池,两种运行方式的生物相丰富;上流式与下流式曝气生物滤池填料高度在40cm和60cm时对有机污染物的去除率分别为62.3%和67.8%,沿水流方向的COD去除率趋于稳定;两种运行方式的曝气生物滤池在填料高度40cm处对SS的去除表现出较高的去除率,分别为76.7%和74.3%,而上流式曝气生物滤池出水的SS的去除率高于下流式曝气生物滤池,分别为96.5%和92.1%。上流式曝气生物滤池的操作方式优于下流式曝气生物滤池。

| Abstract: | Effect of two operation modes on aerated biological filter (BAF) was studied by dynamic simulation experiment. Result showed that film-forming time in up-flow BAF was lower than that in down-flow one, and microbe phase in the reactor was abundant. COD removal rate in two BAF was 62.3% and 67.8% respectively in the 40cm and 60cm media height, which was steady along media height. The two-operation modes presented high SS removal rate with 76.7% and 74.3% respectively in the 40cm media height. However, the SS removal rate of up-flow BAF was higher than that in down-flow one, with 96.5% and 92.1% separately. The up-flow rate BAF was thus super to the down-flow one. |
