摘要为了考察缺氧滤池-膜生物反应器（AF-MBR）对海水养殖废水的处理效果，在膜生物反应器中投加聚氨酯悬浮性填料，并以独立运行的膜生物反应器作为对照.结果表明，组合反应系统的总氮去除率和总有机碳（TOC）去除率分别为92%和90%，高于对照膜生物反应器的86%和85%.并且，前置缺氧滤池和填料的投加也明显缓解了膜污染.通过对两个反应器提取的溶解性微生物产物（SMP）和细胞胞外聚合物（EPS）进行红外光谱和三维荧光光谱的测定，确定了蛋白质和多糖为主要的膜污染物质，并且膜污染物质的减少缓解了膜污染现象.

Abstract：In order to investigate the pollutants removal efficiencies for the anoxic-filter membrane bioreactor (AF-MBR) treating mariculture wastewater, polyurethane suspended filler was added into the membrane bioreactor in contrast with a single membrane bioreactor. The total nitrogen and TOC removal efficiencies in AF-MBR reached 92% and 90%, respectively, which were higher than 86% and 85% in control-MBR, respectively. In addition, the prepositioned anoxic-filter and the added fillers significantly alleviated the membrane fouling. The soluble microbial products (SMP) and extracellular polymers (EPS) extracted from two reactors were analyzed by the infrared spectrum and three-dimensional fluorescence spectra, and protein and polysaccharide were the main membrane foulants. Moreover, the reduction of membrane foulants mitigated the membrane fouling.

Key words： membrane bioreactor removal rate membrane fouling soluble microbial products (SMP) extracellular polymers (EPS)
