摘　　要：分析用于曝气生物滤池的6种填料的特点,通过试验对6种填料在有机物、氨氮、总氮、浊度等的去除效能方面进行比较;并从中优选出两种堆积填料,即阶梯环和多面空心球.结果表明,这两种填料处理效果好,且在冲击负荷下运行稳定.污染物去除效率的差异性是由填料比表面积不同导致的生物膜生长量的差异及空间构型造成的传质差异引起的.The characteristics of 6 kinds of media used in biological aerated filter are analyzed and the removal efficiencies of COD, BOD, NH3 - N, TN and turbidity are compared in this test. Two kinds of stacked media are selected： sloping rings and hollow balls. Results indicated that the running effects are good, and especially steady under shock loading conditions using this 2 kinds of media. The differences of contaminants＇ removal efficiencies resulted from the different quantities of microbe caused by the various specific surface area and the differences of transference influenced by the shapes and structures of the media.
