摘　　要：传统膜技术在处理乳化液的过程中由于膜污染和浓差极化会导致通量迅速下降,故如何强化膜过滤、提高膜通量直接决定了膜组件的处理能力和运行成本。介绍了各种强化乳化液膜过滤处理的物理化学强化技术,阐述了技术原理和优缺点,同时提出了乳化液废水处理的高效集成工艺。In the course of treating emulsion by traditional membrane technology,the flux might dechne rapidly dUe to membrane fouling and concentration difference polarization. Therefore, how to intensify membrane filtration and increase membrane flux determine its treatment efficacy and running cost. The physicochemical intensifying tech- nologies for various kinds of intensifying emulsion membrane filtration treatment are introduced. The technical prin- ciples of these physieochemical methods,and their advantages and disadvantages are expounded. In addition,the high-efficiency-integrated technologies for treating emulsion wastewater are brought forward.
