摘　　要：利用超滤-沸石-活性碳组合填料生物滤池工艺对微污染水源进行了预处理实验研究,结果表明:在水力停留时间为40min,气水比为1:1,水温为15～25℃的实验条件下,对NH3-N、高锰酸盐指数、浊度、色度的平均去除率分别达到97.34%;41.26%;94.40%和89.62%,均高于沸石-活性碳组合填料生物滤池,处理后水质达到了优质地表水源水质标准要求。UF-zeolite-GAC biological filter process was used for pretreatment of micropolluted source water in arid areas, and results showed that under the conditions of HRT 40min, air water ratio 1 ： l and water temperature 15-25℃, removal efficiency of NH3-N, COD Mn, turbidity and color was averaged at 97.34%, 41.26%, 94.40% and 89.62%, which were all efficient than zeolite-GAC biological filter. The treated effluent can meet the requirement of high quality source water.
