| 摘 要： | 根据腐殖填料生物滤池及石英砂普通生物滤池的氨氮去除效率、表面水力负荷及微生物量差异,比较两者氨氮降解速率及比降解速率,对腐殖填料生物滤池的氨氮降解特征进行分析。结果表明,在相同运行方式及外界环境下,腐殖填料滤池表面水力负荷数倍于石英砂普通生物滤池;腐殖填料生物滤池单位体积平均氨氮降解速率高达31.5 g NH4+-N/(m3.d),是石英砂普通生物滤池的5.4倍;腐殖填料生物滤池氨氮比降解速率为4.1×10-2μg NH4+-N/(g微生物碳.d),约为石英砂普通生物滤池的4倍。腐殖填料生物滤池能负载较高的生物量,抗堵塞性能较强,系统内特异微生物对氨氮降解能力较高,是一种优良的降解氨氮的生物滤池。
