| 摘 要： | 以上向流曝气生物滤池为研究对象,对COD的去除效果及影响因素进行了探讨.试验结果表明:上向流曝气生物滤池对COD去除效果具有一定的抗冲击负荷能力,在进水COD质量浓度均值为68.3mgL时,出水氨氮质量浓度均值为26.1 mg/L,去除率为61.8%,去除效果稳定.不同操作条件对COD去除效果的影响为:曝气生物滤池只需较低的曝气量,在V(气):V(水)=5:1的情况下即可获得对有机物较高的去除效率;曝气生物滤池时有机物的降解主要发生在进水端0～60cm范围内;水力负荷在0.5～1.5 m3/(m2·h)的变化范围内.反应器对有机物去除能力基本不受影响;水力负荷和进水COD等2种途径带来的COD容积负荷变化对其去除率没有明显的区别,并且有很强的抗冲击负荷的能力. |

| Abstract: | The efficiency and influencing factors of COD removal in an up-flow biological aerated filter (BAF) were carried out. It was demonstrated that the up-flow BAF could achieve a certain anti-shock loading capability as far as the COD removal efficiency was concerned. When the average inflow COD concentration was 68.3 mg/L, the outlet COD concentration was 26.1 mg/L with an average removal rate at 61.8%, and the removal efficiency was stable. The different operation conditions which influenced the COD removal e... |
