多隔室厌氧折流板反应器(ABR) 的水力特性试验研究

对ABR反应器的水力流态进行了示踪剂试验,分析了特征截面面积对ABR水力特性的影响,采用停留时间分布(RTD)法研究了不同进水COD浓度和HRT条件下ABR反应器的水力特性,结果表明不同进水COD浓度时ABR反应器的RTD曲线相似,表明进水COD浓度不是影响ABR水力特性的主要因素;不同HRT条件下RTD曲线差异很大,表明HRT对ABR的水力特性影响较大,随着水力停留时间的延长,N值增大,1/Pe减小,ABR的流态趋于推流流态,随着HRT的缩短,N值减小,1/Pe数增大,ABR反应器趋于完全混合流态.

Pilot study on hydraulic characteristics of anaerobic baffled reactor

The tracer test of hydraulic characteristics in ABR was studied and the effects of special section on hydraulic characteristics in ABR were analyzed.Residence time distribution(RTD) method was used to investigate hydraulic characteristics of ABR under different feed and HRTs conditions.The results are as follows:RTD-curve of ABR under different influent COD concentration was similar,showing that the hydrodynamics of reactor did not appear to be influenced by changing the influent COD concentration;RTD-curve of ABR under different HRTs was different,showing that the hydrodynamics of reactor were influenced by changing HRT,the values of N increased and the number of 1/Pe decreased with HRT increasing and the hydraulic flow of ABR tended to be plug-flow pattern,the values of N decreased and the number of 1/Pe increased with HRT decreasing and the hydraulic flow of ABR tended to be completely mixed pattern.
