| 摘 要： | 文章以升流式曝气生物滤池(Up-flow Biological Aerated Filter,UBAF)模拟处理二级生活污水为研究对象,研究了UBAF对COD和NH4+-N的去除规律,考察了有机负荷、水力负荷和载体高度对两者去除效果的影响。结果表明,经UBAF处理后的水质稳定,对COD、NH4+-N平均去除率分别为71.88%和75.28%;有机负荷和水力负荷对反应器污染物处理效果影响很大,试验得到的最佳有机负荷和水力负荷分别为4.67kg·m-·3d-1和7m·h-1;UBAF内存在不同菌群沿层变化的特点,在进水端80cm段以异养菌为主,而在出水端以硝化菌为主,随着有机负荷增加,菌群分层现象减弱。

| Abstract: | Up-flow Biological Aeration Filtration(UBAF) was used to treat simulated secondary domestic sewage, removal rules of COD and NH4+-N by UBAF were studied, and the effect of organic load, hydraulic load and media height on removal efficiency of the two parameters was investigated. The results showed that a stable water quality of effluent was obtained, and average removal efficiencies of COD and NH4+-N were 71.88% and 75.28%, respectively. The treatment efficiency of pollutants was influenced evidently by org... |
