摘　　要：用曝气生物滤池工艺(BAF)处理微污染源水中的持久性有机污染物(PCBs),研究了曝气生物滤池对微污染源水中PCBs的去除效果,考察了气水比、水力停留时间、滤料材质等因素对曝气生物滤池处理效果的影响。试验表明:陶粒滤料BAF较沸石滤料BAF更能去除微污染水中的PCBs,在气水比为1∶1,水力停留时间为1.2h去除率最高,平均去除率为52%。Further study has been conducted to evaluate the Performance of BAF removing organic matters (PCBs) in micro-scale polluted source water. Furthermore,several factors considered affecting BAF process have been examined which are the gas-water ratio、hydraulic retention time(HRT)、different medias of BAF.The test results show that: the performance of haydite BAF is better than zeolite BAF.With the gas- water ratio for 1∶1,HRT for 1.2 h,removal rate of the haydite BAF gets to top,and average removal rate is 52 %.
