摘　　要：通过对运行参数及其影响因素等条件的实验，考察生物陶粒滤池在饮用水预处理过程中对氨氮的去除效果。研究表明，生物陶粒滤池在常温下对氨氮有着良好的去除效果，去除率可维持在90％以上。适宜的滤速为4～6m／h，相应的水力停留时间为20～30min。This article is about an experiment to concerns biofiltration for the removal of NH4-N from drinking water sources in which An aerated biological filtration reactor with cultivate padding was used. The research indicates that under normal temperatures, the removal efficiencies of NH4-N in the ABF reactor are marked. The efficiencies of removal of NH4-N were over 90%. The best HRT for operation was 20～30 min.
