移动床生物膜反应器及其应用

介绍了移动床生物膜反应器（MBBR）的特点，讨论了MBBR中填料的材质、大小、形状、比重、数量及其有效比表面积，搅拌类型和搅拌方式，有机负荷的大小，水力停留时间，废水pH的变化等因素对移动床生物膜反应器运行效果的影响，综述了单独MBBR工艺、MBBR与活性污泥共池工艺，MBBR与其他工艺的组合工艺在废水处理中的应用现状。

Moving Bed Biofilm Reactor and Its Application

The features of a moving bed biofilm reactor (MBBR) were introduced. Effects of various factors on the performance of the MBBR were discussed such as the texture, size, shape, specific gravity, quantity and effective specific surface area of the filling materials in the MBBR, as well as types and modes of the stirring, organic Ioadings, hydraulic retention time, changes in pH value of the wastewater, and etc. The present application of the single MBBR process and combined with activated sludge process or other ones in the wastewater treatment was reviewed.
