• 摘要：对SBR法的基质降解过程动力学进行了分析和讨论,推导出一级反应动力学关系式,确定了其常数的求定方法,并提出了一种求定不可生物降解COD的新方法,继之以试验结果对动力学关系式进行了拟合。对体系的脱氢酶活性变化过程进行了研究,探讨了基质脱氢酶活性与基质浓度的关系。

• Abstract：Kinetics of substrate degradation was studied and a firstorder reaction equation was developed on SBR process. The method for determining the kinetic constants and non-degradable COD was proposed and the equation was simulated by experimental data. Verification of dehydrogenase with aeration time and the relation between substrate dehydrogenase activity and substrate concentration were also discussed.

• Key words：SBR process  kinetics,substrate,dehydrogenase activity
