摘　　要：　针对受污染的黄河水源水,进行生物陶粒滤池试验研究。结果表明,生物陶粒滤池预处理能全面净化受污染黄河水的水质。在气水比为0.25:1、滤速为5.1m/h的条件下,对CODMn、NH+2—N、的去除率分别为4.8%—22.7%,20%—77.6%,75%—98.3%。4—N、NO-对UV254和藻类的去除率分别为7.3%—30.4%和24.4%—41.8%。Research on Yellow River light-poluted water pre-treatment by using bio-ceramic filter is conducted. It's shown that the source water quality can be greatly improved by the bio-ceramic filter pretreatment.The removal rate of CODMn、NH^+_4—N and NO^-_2—N is 4.8%—22.7%,20%—77.6%,75%—98.3% respectly.Moreover, the removal rate of UV_254 and algae is 7.3%—30.4% and 24.4%—41.8% when gas/water ratio is 0.25:1 and the hydraulic load is 5.1m/h.
