摘　　要：本文对两种厌氧流化床的水力混合特性进行了研究。结果表明,厌氧流化床在无回流时均属推流型流态,在有使填料开始膨胀的回流条件下均属完全混合型流态。根据试验数据,分析了完全混合流态下两种厌氧流化床的容积有效利用率。This paper presents the studies of hydraulic mixing characteristics in anaerobicfluidized beds.The results show that fluidized beds without and with recirculation forming asmaller degree of expansion are plug-flow reactors and continuous stirred tank reactors(CSTR),respectively.Accoraing to experimental data,the effective volume fractions of anaerobicfluidized beds,which are CSTR,are analyzed.
