摘　　要：以染料为示踪剂进行示踪脉冲响应实验,研究了圆柱形厌氧折流板反应器(CABR)在不同水力停留时间(HRT)下的停留时间分布(RTD)曲线和水力特性参数.实验结果表明:当HRT在1h至9h变化时,CABR反应器的C-θ曲线趋于正态分布;死区容积率Vd/V在0.154～0.026之间;完全混合槽串联数N值介于6.76～8.26之间.这说明CABR反应器具有容积利用率高和推流化程度强的特点.The Residence Time Distribution （RTD） curves and hydrodynamic characteristics parameters of Cylinder Anaerobic Baffled Reactor （CABR） in several HRT were studied through the experiment of impulse response which used dye as tracer. The results show that the C-O curves of CABR tend to be normal distribution; the dead-volume ratio（Vd/V） of CA- BR is between 0. 154 and 0. 026;the number of continuous stirred-tank is between 6.76 and 8.26 when HRT vary from lh to 9 h. These results show that CABR have the characteristics of high capacity utilization and strong plug-flow.
