| 摘 要： | 采用中试规模复合生物滤池处理城市高污染水体,考察了滤池的最佳运行参数以及对氮和有机物的去除效果。结果表明:滤池容积负荷宜控制为0.3～0.5 kg COD/(m3.d),水力负荷4.5～5 m3/(m2.d),适宜的通风比为9%,当C/N为5～8时,滤池COD、NH4+-N和TN平均去除率分别为80%、83%和63%,达到高效同步硝化反硝化状态。

| Abstract: | A pilot-scale composite biofilter was developed to treat the urban highly polluted water. The study was conducted to investigate the optimal operation parameters of biofilter and the removal efficiency of nitrogen and organic matter. The results show that the volume loading, hydraulic loading and ventilation ratio should be controlled at 0.3 to 0.5 kg COD/(m3·d), 4.5 to 5 m3/(m2·d) and 9%, respectively. With the C/N ratio of 5 to 8,the average removal rates of COD, NH4+-N and TN were 80%, 87% and 63%, respectively, which achieved the efficient state of simultaneous nitrification and denitrification. |
