摘　　要：随着水体污染的加剧,越来越多的深度处理工艺应用在给水处理中。本文研究了生物滤池和膜生物反应器(MBR)对微污染水源水中的内分泌干扰物苯乙烯的处理效果,试验证明,生物滤池和MBR对苯乙烯均有较好的去除率。曝气生物滤池对苯乙烯的去除是滤料吸附、曝气和微生物吸附降解三方面共同的作用。MBR连续流试验表明,膜生物反应器对苯乙烯去除率在95%以上,主要是依靠膜生物反应器内微生物的吸附和降解、膜组件内部的曝气以及膜的微孔截留共同作用。With the intensification of water pollution, more and more advanced treatment technologies are widely used in water treatment. The removal efficiency on endocrine disruptor styrene in micro-contaminated raw water by biological aerated filters and membrane bioreactor （MBR） was studied. The experiment results showed there was a good removal efficiency of styrene, both by biological aerated filters and MBR. The styrene removal efficiency in biological aerated filter process was a joint action of the filter sorption, aeration, microbial degradation and adsorption. The continuous flow test of MBR showed that styrene removal rate in MBR was more than 95%, the main reason was the joint action of the microbial degradation and adsorption, membrane aeration, micro-porous interception membrane.
