摘　　要：膜曝气生物膜反应器(MABR)是一种新颖的膜-生物处理组合工艺.在MABR中,曝气膜既提供曝气又兼做生物膜生长的载体.气相(曝气膜内腔)中的氧是通过膜/生物膜的界面扩散进入生物膜内,而液相(废水)中的底物是从生物膜/液相界面上进入生物膜.MABR突出特征是无泡曝气以及氧和底物的异向传质导致的生物膜功能活性层化,对高需氧量、高氨氮、易挥发性污染物的废水处理具有明显优势.本文综述了MABR的工作原理、构造和特性、膜材料选择、工艺形式、应用、技术经济比较以及研究进展,指出当前MABR研究应用中存在的问题,并展望了今后的发展前景.Membrane-aerated biofilm reactors（MABRs） represent a novel biotreatment technology.In an MABR,the gas-permeable membrane is used as the diffuser for bubbleless aeration as well as the carrier for biofilm growth.Oxygen from the biofilm-membrane interface（by oxygen diffusing through the membrane） and substrates from the biofilm-liquid interface are supplied from two opposite directions to the biofilm,in contrast to those from the same side in conventional biofilm bioreactors.MABR is characterized by bubbleless aeration and functional activity stratification of biofilm with counter-diffusion.MABR can be potentially utilized to effectively treat wastewaters of high oxygen-demand,high ammonia or volatile organic pollutants.This article reviews,in a comprehensive manner,the operational concept,characteristics,membrane materials and applications of the MABR process as well as the prospects and priorities for MABR technology development.
