摘　　要：近年来,膜生物反应器(MBR)工艺受到广泛关注,对MBR的研究和应用范围不断发展,但作为一种新兴技术,MBR工艺还存在许多不完善的地方。本文以提高MBR工艺污染物降解率为目的,对实验室研究过程中发现的问题做了论述和探讨。文中提及膜污染、脱氮除磷效率低、污泥粒径小、活性降低等问题,并针对这些问题提出了相应的改进建议。In recent years,membrane bioreactor has attractted extensive attention,research and application of membrane bioreactor have developped continuously,but as a rising technology,it has many imperfections.For the purpose of improving the efficiency of the removal rate of the pollutants,problems identified during the laboratory studies had been discussed in this paper.Membrane fouling,low removal ability of nitrogen and phosphorus,smaller particle size and decreased activity have been mentioned in the paper,and suggestions have been proposed to solve these problems.
