摘要
采用沸石-陶粒曝气生物滤池,对以有机物和氨氮为主要污染物的微污染水源水进行了处理试验,结果表明:沸石-陶粒曝气生物滤池对微污染水的处理效果较好,在水力停留时间为15～60min,气水体积比为1,水温为17～26℃时,CODMn,NH3-N,UV254的平均去除率分别为32.25%,92.57%,9.73%。气水比、进水有机物负荷对沸石-陶粒曝气生物滤池的运行效果有一定的影响。
Zeolite-Ceramics biological aerated filter was used in the test of treatment of slightly polluted source water which mainly polluted by organic matters and ammonia nitrogen. The results show that： zeoliteceramics biological aerated filter has a good effect on slightly polluted water treatment, when the hydraulic retention time is 15 - 60 min, the gas/water ratio is 1, the water temperature is 17 - 26℃, the average removal rate of CODMn, NH3-N, UV254 are 32.25%, 92.57% and 9.73% respectively. The gas/water ratio and the organic loading of the influent water affect the running effect of biological aerated filter to some extent.
