| 摘 要： | 膜曝气生物反应器是一种利用透气膜进行曝气的污水生物处理组合新工艺.膜曝气的主要特点在于无泡曝气和特殊结构的生物膜.无泡曝气可提高传氧效率,在高浓度废水或含挥发性有机物废水的处理中具有优势.曝气膜上生长的生物膜具有传质异向性,这一特点使其具有同步除碳脱氮的潜力.介绍了膜曝气生物反应器的工艺特点,总结了国内外对于膜曝气生物反应器在废水处理方面的研究进展,指出当前膜曝气生物反应器应用中存在的问题,并展望了今后的发展前景.

| Abstract: | Membrane aerated bioreactors(MABR) is a novel combination wastewater treatment process where gas-permeable membranes are applied to aeration.MABR is characterized by bubbleless aeration and special biofilm attached on the aerated membrane.Bubbleless aeration provides a high oxygen transfer rate and has a potential in treatment of high strength wastewater or wastewater containing volatile organic substances.The biofilms attached on the aerated membrane with counter diffusion of oxygen and organic matter can be utilized to remove carbon and nitrogen simultaneously.In this paper,the characteristics of MABR were described.Research process in this field was reviewed;and the future topics were prospected. |
