  • 摘要: 以吡啶、喹啉和吲哚为单一碳源,通过摇床实验进行反硝化过程动力学研究。实验结果表明,以吡啶和喹啉为单一碳源的反硝化过程中,NO2--N的积累率分别达到了53.4%和16.4%;以吲哚为单一碳源的反硝化过程中,NO2--N的积累现象不明显,最高不超过4%。以NO3--N+0.6 NO2--N作为反硝化电子受体,采用基于Monod 方程的动态模型进行拟合, 拟合曲线与实验测定值相关性良好。其次,采用基于Monod 方程的微分方程组模型,也能够很好地拟合3种碳源条件下反硝化过程硝酸盐、亚硝酸盐质量浓度的变化,得到相应的动力学参数。
    Abstract: Through the shaking table test,kinetics of denitrification process with pyridine,quinoline and indole as sole carbonsource were studied respectively.When pyridine and quinoline were used as the sole carbon source, the maximumNO2--N accumulation percentage reached 53.4% and 16.4%,respectively. In contrast, NO2--N scarcely accumulated when indole was used as the sole carbon source, and the highest NO2--N accumulation percentage was hardly higher than 4%. Monod model was adopted to fit the test data obtained under conditions of nitrite accumulation,NO3--N+0.6 NO2--N as the electronic acceptor of denitrification. The results show that there is a good correlation between the fitting curve and the experimental measurement. Variations of nitrate and nitrite during denitrifiation process with the three different carbon sources can be well described by differential equations model based on Monod equations.
