摘　　要：通过实验证明循环移动载体生物膜反应器(CMCBR)的流态特性接近完全混合,利用能量方程对反应器的水力性能进行分析,得出影响反应器水力性能的主要因素有供气量、提升区与回落区的面积比、阻力系数和有效水深。在不同气量和填充比条件下对充氧性能加以比较,并对充氧性能的变化机理进行了探讨。The circulated moving carrier biofilm reactor (CMCBR) is a new wastewater treatment technique that fillers with biofilm growing on their surface circulate in the reactor, thus increasing contact effect between flow and fillers. In this paper, it has been proved that CMCBR is more like a CSTR according to the hydraulic characteristic experiment. Using energy equation the flowing characters are discussed and some main factors are pointed out. Aeration performance is also compared and analyzed in the different gas flow rates and filling rates.
