摘　　要：对循环移动载体生物膜反应器进行了研究。通过改变循环移动载体膜生物反应器的结构尺寸,研究了反应器内氧转移系数的变化。研究结果认为在反应器的升、降流区面积之比为2/3,挡板上方液面高度和底隙高度均为250mm,填料的填充比为50%时,氧转移效率最高。Changes of oxygen transfer coefficient were studied in a test of Circulated Moving Carrier Bio-membrane Reactor(CMCBR)by changing the design and size of the CMCBR.It was shown by the result of the test that the oxygen transfer coefficient was the highest when the ratio of the area of the flow-increasing zone of the reactor to that of the flow-decreasing zone was2/3,the height of the liquid level above the baffle plate and the height of the bottom clearance were both250mm and the filling ratio of filler was50%.
