摘　　要：曝气系统是膜生物反应器(MBR)的关键单元,直接关系MBR的运行效能。与常规大气泡不同,微气泡具有独特的理化特性,其曝气充氧能力强、污染物去除效率高、通气量大、节约能耗等优点,近年来在MBR中的应用日益受到关注。详细介绍了微气泡曝气技术在强化气液传质、膜污染控制、污染物的高效去除等方面的研究进展与应用现状,分析了微气泡曝气应用于MBR中的技术优势与应用前景,并对其应用中存在的问题及未来的研究方向进行了分析与展望。Aeration system is a critical unit of membrane bioreactors(MBR), which directly related to the operational efficiency of MBR. Different from conventional large bubbles, microbubbles process has unique physic-chemical properties, which shows many advantages such as: strong aeration oxygenation capability, high pollutants removal efficiency, large ventilation volume, and energy saving, therefore, the application of microbubble aeration in MBR has attracted more and more attention in recent years. The related research and application progress of microbubble aeration technology were introduced in details from aspects of gas-liquid mass transfer strengthening, membrane fouling control, efficient contaminants removal, and so on. The technological superiority and the existing problems of microbubble aeration applied in MBR were analyzed with its application prospect and future research direction pointed out at the same time.
