摘　　要：在水力负荷为5m／h，汽水比为1-2的条件下，在曝气生物滤池（BAF）正常稳定运行时，对曝气生物滤池不同滤料层高度的除污性能进行研究分析。实验结果表明：曝气生物滤池对浊度、COD、NH2-N及色度的去除均有不错的去除效果。并且浊度、COD、色度的去除主要发生在滤料高度为0～50cm处，而NH4-N的去除主要发生在滤料高度的50～90cm处。When the filtration rate is 5m /h and the ratio of air to water 1 to 2,the biological aeruted filter （BAF） is operated normally and stably, analysing the contamination perfor mance of the different filter material height in BHF. The results show that the BAF have relatively good removal effect for Turbidity, COD, NH4＋-N and chroma,the decontamination of COD,turbidity and chroma mainly at a filter material height of 0-50 cm, and the decontamination of NH4＊-N maily at 50-90cm.
