移动床生物膜反应器(MBBR)及其耦合工艺的研究进展

Review of Moving Bed Biofilm Reactor(MBBR) and Its Coupling Process

随着人们对含氮废水所引起的水体富营养化等环境问题的重视以及污水排放标准日益严格,近年来移动床生物膜反应器(MBBR)在有机物降解以及生物脱氮等方面的应用引起了越来越广泛的关注,本文从MBBR反应机理的角度综述了MBBR工艺应用过程中的影响因素(如溶解氧、温度等),此外通过MBBR与其他工艺的耦合,阐述了MBBR的使用现状,最后对MBBR在实际工程应用中出现的问题提出展望。

With the attention paid to environmental problems such as water eutrophication caused by wastewater containing nitrogen and increasingly stric sewage discharge standards, the application of MBBR process in organic degradation and biological denitrification has attracted more and more attention in recen years. This paper reviews the influencing factors(such as dissolved oxygen, temperature, etc.) in the application of MBBR process from the perspective of MBBR reaction mechanism. In addition, through the coupling of MBBR and other processes, the application status of MBBR is described. Finally, the problems in practica engineering application of MBBR are prospected.
