摘　　要：移动床生物膜反应器运行过程中填料不易获得均匀分布,在大尺度推流式反应器中经常发生填料堆积现象。通过研究低填充率下填料运动模式,获得了类似于Boltzman方程的推流式反应器内填料分布方程,试验结果与方程预测分布基本吻合。It is difficult to gain uniform distribution of carriers in moving bed biofilm reactor.Carriers often accumulate in large-scale push-flow reactor.Deduction was carried out by studying the moving model of carriers at low packed rate and the equation is similar to the distribution of Boltzman.The result is in good coincidence with test data.
