膜生物反应器最新研究及纯氧曝气在污水处理中的应用分析

Latest research on membrane bioreactor and pure oxygen aeration Application analysis in sewage treatment

近年来,由于随着水资源日益匮乏和污水排放标准的提高,使得膜生物反应器(MBR)受到了广泛的关注。文章对MBR的主要类型和特点进行了简要介绍,并对膜性质、膜组件、MBR工艺和膜污染的最新研究进行了较为细致的分析,并在曝气方面对纯氧曝气与空气曝气进行了对比,在此基础上指出了今后纯氧曝气与MBR工艺相结合的研究趋势。

In recent years, membrane bioreactors have received extensive attention due to the increasing shortage of water resources and the improvement of wastewater discharge standards. This paper briefly introduces the main types and characteristics of MBR, and conducts a detailed analysis of the latest research on membrane properties, membrane modules, MBR processes and membrane touling, and aerates oxygen and air aeration in aeration. Based on the comparison, the research trend of combining pure oxygen aeration with MBR process is pointed out.
