摘　　要：以Cl-为示踪剂,采用停留时间分布法(RTD)研究在清水和有污泥稳定运行条件下,HRT对异波折流板反应器和平板折流板反应器水力特性的影响,并进行了对比分析。结果表明,进水为清水、HRT为2～8h,HRT对平板折流板反应器的水力特性的影响比异波折板反应器更为显著,异波折板反应器的流动模式处于平推流和完全混合的"中间状态"。相同HRT条件下异波折板反应器的死区率小于平板折板反应器,异波折板反应器内接种污泥后,死区比清水反应器时有所增加,生物死区成为死区大小的主要贡献者。The hydraulic retention time （HRT） on the different folded plate reactor and the plate baffle reactor hydraulic characteristic influence in the clear water were studied by taking Cl^-as the tracer material, and used the resident time distribution law （RTD） and the contrastive analysis under the sludge steady operation condition was carded on. The result indicated： when enter clear water, HRT 2-8 h, HRT is more remarkable to the plate baffle reactor＇s hydraulic characteristic influence then to the different folded plate reactor, the different folded plate reactor＇s mobile pattern is at the even drift and mixes ＂the compound state＂ completely. Under the same HRT condition the different folded plate reactor reactor＇s dead area percentage is smaller than the plate baffle reactor, in after the different folded plate reactor vaccinates the sludge, dead area compared to the clear water reactor increased, the biological dead area becomes the dead area size main contributor.
