Abstract: With the popularity of higher education and the increasing emphasis on it, college and university campus planning is being perfected increasingly and construction of new campus is booming. In the context of ecological civilization construction, as a public premises, treating and recycling sewage in accordance with the standard has been one of the essential measures to protect and manage university campus environment. Most sewage treatment plants in many universities adopt MBR technique as treating process. MBR technique is a good sewage treatment technique, with the advantages of high efficiency, simple operation, steady functioning, compact construction and easy to operate automatically. The technique can meet sewage treatment demands and realize grey water reuse in universities. The paper made a review and illustrates the application of MBR technique to large-scale sewage treatment in universities in recent years.

1 MBR工艺概述
膜生物反应(Membrance Bio-reactor,MBR)工艺是现代膜分离技术与生物技术有机结合的一种新型废水生物处理技术。把膜分离技术中的超微滤技术与污水处理中的传统活性污泥法相结合,用膜组件代替活性污泥法中的二沉池,就构成了MBR工艺。该工艺能达到污染物降解和泥水分离的目的,减少占地和造价,流程简单、运行稳定、结构紧凑,具有良好的应用前景[1]。MBR技术在2011年被列入《国家鼓励发展的重大环保技术装备目录》,其已成为我国水处理技术的重点发展方向。
考虑到MBR工艺在同步脱氮除磷及膜污染控制方面还有待进行深入研究,近年来,很多研究人员将MBR与传统的生物脱氮除磷工艺相结合,形成了新型污水处理组合工艺,例如,A2/O-MBR、SBR-MBR等,并且取得了较好的处理效果[2]。……
