摘　　要：In this study,the characteristics and kinetics of substrate degradation in anaerobic baffled reactor(ABR) were investigated by using glucose as dilute organic wastewater.Operation conditions,such as hydraulic residence time(HRT),sludge concentration and temperature were proved to have effects on the treatment efficiency of ABR through the analysis on the kinetics of substrate degradation.Declining growth rate constant K2 was obtained in a small experimental ABR using glucose as influent,based on the experimental results at different temperatures.According to the analysis of Arrhenius relationship,temperature did not affect K2 greatly.This is one of the reasons why comparatively good treatment efficiency may still be achieved at a lower temperature.In the experiment,activation energy(1.92 ×104 J·mol-1) was also obtained from the Arrhenius equation.In this study, the characteristics and kinetics of substrate degradation in anaerobic baffled reactor （ABR） were investigated by using glucose as dilute organic wastewater. Operation conditions, such as hydraulic residence time （HRT）, sludge concentration and temperature were proved to have effects on the treatment efficiency of ABR through the analysis on the kinetics of substrate degradation. Declining growth rate constant K2 was obtained in a small experimental ABR using glucose as influent, based on the experimental results at different temperatures. According to the analysis of Arrhenius relationship, temperature did not affect K2 greatly. This is one of the reasons why comparatively good treatment efficiency may still be achieved at a lower temperature. In the experiment, activation energy （1.92 × 10^4 J · mol ^-1） was also obtained from the Arrhenius equation.
