摘　　要：在不同进水负荷及水力停留时间下,利用LiCL作为示踪剂对六隔室的ABR反应器进行水流流态的研究。研究表明:ABR反应器具有单个隔室完全混合流态而整体水流方向推流流态的复杂的混合流态;水力停留时间和进水负荷是影响ABR反应器水力特性的主要因素;含泥反应的反应器死区率(26.20%～58.56%)远远大于清水(5.79%～12.68%)。Using LiCL as the tracing substance under the different influent concentration and HRT,the paper studied the hydraulic flow characteristics of ABR with 6 compartments.The results showed that the ABR pre-sented the complete mixing flow in each compartments and the complicated mixing flow situation in the whole flow trend,the HTR and influent loading rate both greatly effect the hydraulic characteristics of ABR,the dead zone percentage of the reactor with the influent concentration was between 26.20% to 58.56%,which was much higher than the clear water reactor with dead zone percentage between 5.79% to 12.68%.
