摘要
针对日益严苛的废水排放标准,必须提高废水处理工艺脱氮除磷和对难降解有机物的去除性能。膜生物反应器(MBR)作为膜分离与生物技术有机结合的污水处理技术,具有系统处理效果好、容积负荷高、占地面积小,节省空间等优点。文章梳理了MBR在废水脱氮除磷及难降解有机物处理等方面的应用情况,介绍了MBR各种生物强化技术研究现状,为新型MBR技术的开发提供了支持。
In order to meet the increasingly strict wastewater discharge standards, it is necessary to improve the performance of wastewater treatment process for removal of nitrogen, phosphorus and refractory organics. Membrane bioreactor （MBR） is one of the wastewater treatment technologies combined with membrane separation and biological degradation. In comparison to the conventional activated sludge systems, MBR has such advantages as superior effluent quality, higher volume load rate, smaller volume and footprint, etc.. In this paper, the application of MBR in removal of nitrogen, phosphorus and refractory organic compounds is reviewed and the research status of MBR in various kinds of bioaugmentation technologies is introduced, providing support for the development of new MBR technologies.
