摘　　要：粉煤灰加气颗粒和沸石颗粒作为曝气生物滤池填料在相同条件下进行挂膜试验,结果得出:粉煤灰加气颗粒的挂膜速度与沸石颗粒大体相同,最终其CODCr去除率(60%)比沸石填料(55%)略高;沸石填料的NH4+-N处理率高于粉煤灰加气颗粒,达70%左右。Fly-ash cellular granule and zeolite granule were tested on their start-up in the same conditions.The test results showed that the start-up speed of the fly-ash cellular granule was similar with the zeolite media,and the removal rate of COD_Cr(60%)was slightly higher than the zeolite biofilm(55%)in the end,but the NH+_4-N removal rate of the zeolite biofilm was higher than the fly-ash cellular granule,up to about 70%.
