| 摘 要： | 通过动态模拟试验，考察了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在40cm和60cm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的去除率较高，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: | The effect of two operation mode on biological aerated filter (BAF), up-flow and down-flow, was investigated by dynamic simulation experiment. The experiment result showed, the form-film time of up-flow BAF was lower than down-flow BAF, and the kind of microbe in the reactor was abundant. Respectively, the COD removal rate of up-flow BAF and down-flow BAF was 62.3 % and 67.8 % in the 40cm and 60 cm media height. And the COD removal rate was steady along media height. The two operation mode presented high SS removal rate on 40cm media height. The removal rate respectively was 76.7 % and 74.3 %. However, the SS removal rate of up-flow BAF was higher than that of down-flow BAF, which was 96.5 % and 92.1 %. The up-flow rate BAF was super to the anther operation, the down-flow BAF. |
