摘要

本文研究了折流板厌氧反应器（ABR）在常温下处理低浓度有机废水有机污染物降解动力学方面的问题。根据对ABR反应器有机污染物降解动力学模型的研究，得出ABR处理效率与水力停留时间（HRT）、污泥浓度、分格数（m）及温度有关。小试采用葡萄糖配制的模拟生活污水进行试验，求得不同温度下减速增长的速度常数K2值。由Arrhenius公式求得了活化能E值1.92×104 J.mol-1，这表明本试验中温度对K2值影响不大，从而在理论上说明在温度较低时ABR反应器仍有较好处理效果的原因。

Abstract

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 temperatureIn the experiment

activation energy(1.92 ×104 J.mol-1) was also obtained from the Arrhenius equation.
