| 摘 要： | 在曝气吸附生物滤池中分别加入不同的吸附剂作填料,对造纸废水进行深度处理,以此选择出最佳的吸附填料。研究结果表明:以活性炭和3A分子筛为填料的曝气吸附生物滤池深度处理造纸废水的效果最佳,废水COD的去除率可达78%;直径3mm的不规则形状颗粒活性炭比其他粒径和形状的活性炭处理效果更好;活性炭与石英砂或铁屑混合组成的填料,更有利于造纸废水COD和SS的去除。

| Abstract: | Different media were filled in the biological aerated adsorption filter to treat paper effluent in order to find out the best adsorption media. The results show that the effect of using active carbon and 3A molecular sieve as media is the best to treat paper effluent in the biological aerated adsorption filter, with the COD removal rate of 78%. The irregular shape active carbon with the grainy diameter of 3mm is better than other active carbon on wastewater treatment. That active carbon is mixed with quartz sand or iron powder will be benefit for removal of COD and SS. |
