摘要
利用沸石-活性碳组合填料生物滤池对黄河兰州段微污染原水预处理效果进行了实验研究,结果表明;在水力停留时间为40min,气水比为1:1,水温为25-30℃的实验条件下。对NH4-N、CODMn、UV254、浊度、锰的平均去除率分别为95.0%、32.68%、9.42%、70.1%、91.3%,预处理效果明显,且具有较强的抗冲击负荷能力。
Zeolite-GAC biological filter was used for pretreatment of mlcro-polluted source water of Lanzhou section of Huanghe River. The result shows that under the conditions of HRT 40min, air-water ratio 1 : 1, and water temperature 25-30℃, the removal rates of NH4 -N,CODMn,UV254 ,and turbidity are averaged at 95% ,32. 68% ,9.42% and 70. 1% ,respectively,with high resistance to shock loading.
