以呼吸速率为基础判断活性污泥抑制类型的研究

通过对活性污泥工艺中微生物抑制动力学的理论分析,把好氧微生物呼吸速率动力学引入与抑制动力学的研究中。在对不同抑制类型的呼吸速率动力学分析的基础上,比较基质降解的动力学公式和呼吸速率的动力学公式的差异,确定了判别竞争性抑制和非竞争性抑制的方法,就是通过测量投加抑制物和不投加抑制物的情况下最大呼吸速率的变化情况,当不投加抑制物和投加抑制物最大呼吸速率的比值超过1.2~1.5时,可以认为该抑制为非竞争性抑制。本文对该方法进行了试验研究。

Study on Judgment of Inhibition Type Based on Respiration Rate in Activated Sludge Process

In this article,through theoretical analysis about inhibition kinetics in activated sludge process,kinetics of respiration rate is inducted into the study of inhibition kinetics.Based on analysis of respiration rate kinetics of all kinds of inhibition types,a new method of judging inhibit type in activated sludge process used respiration rate is put forward after comparing the kinetic equation of substrate degradation with respiration rate.Through measuring the maximal respiration rate with the inhibitor and without the inhibitor,the non-competitive inhibition can be confirmed when the ratio on two maximal respiration rate is beyond 1.2-1.5.Afterward,an experiment about this method is carried out.
