盐度对膜生物反应器处理含盐废水影响的研究进展

摘要

总结了国内外采用膜生物反应器( MBR)处理含盐废水的研究进展,分析了盐度对有机物去除的影响、对脱氮效果的影响、对总磷去除的影响以及对微生物活性和膜污染的影响.指出当前MBR处理高盐度废水的研究热点主要是如何降低对各类功能微生物活性的抑制作用,以及降低溶解性微生物产物、胞外聚合物的释放量,从而减轻膜污染,但目前大多数的研究仍处在实验配水阶段.最后还对今后的研究方向进行了展望.%The reach progress of applying membrane bioreactor to treat wastewater with salinity was reviewed, including the effects of salinity on organism removal, denitrification, TP removal and membrane fouling. The research of high salinity wastewater treatment by MBR process should be focus on how to reduce the inhibition of salinity to functional microorganism, how to decrease the soluble microbial product and prevent the release of extracellular polymers, so as to alleviate the membrane fouling, while most of the research was still in the experimental stage. The direction of further work was prospected in the end of the paper.
