【摘要】：膜分离技术具有能耗比较低、可常温运行、适用对象广泛、装置简单、易于自动控制和环境友好等优点,目前已普遍用于污水处理、海水淡化、电子、化工、医药等领域。然而在膜技术工程化应用过程中存在的膜污染问题,尤其是不可逆的微生物污染,严重影响了分离膜分离性能和使用寿命,进而影响分离过程的持续性和经济性。本文从分离膜微生物污染的角度出发,总结归纳微生物污染的形成过程及特点,并针对微生物污染问题,着重论述了国内外抗菌分离膜的研究现状,详细介绍了被动抗黏附型、主动杀伤型及程序式复合型三类抗菌策略,对其制备方法、抗菌机理以及存在问题进行了阐述与分析,在此基础上,进一步探讨了抗菌分离膜的未来发展趋势。
[Abstract]:Membrane separation technology has been widely used in sewage treatment, seawater desalination, electronics, chemical industry, medicine and other fields, because of its advantages of low energy consumption, room temperature operation, wide application object, simple device, easy automatic control and friendly environment. However, the membrane fouling problem, especially the irreversible microbial contamination, has seriously affected the separation performance and service life of the separation membrane, and further affected the sustainability and economy of the separation process. In this paper, from the point of view of membrane microbial contamination, the formation process and characteristics of microbial fouling are summarized, and the research status of antimicrobial separation membrane at home and abroad is emphatically discussed, and the passive anti-adhesion type is introduced in detail. Three kinds of antimicrobial strategies of active killing type and program compound type were described and analyzed. The preparation method, antibacterial mechanism and existing problems were described and analyzed. On the basis of this, the future development trend of antibacterial separation membrane was further discussed.
