深床过滤中的生物反硝化动力学实验研究

Experimental Study on Kinetics of Bio-denitrification in the Process of the Deep Bed Filtration

研究了深床过滤过程中的生物反硝过程,构建了相应的动力学模型,分析了反硝化脱氮中的传质及生物反应过程对反应动力学的影响;实验结果证实了升流式深床过滤过程中的生物反硝化反应动力学级数在1/2-1级之间,并与所建动力学模型基本吻合.图2,表1,参9.

Bio-denitrification process was discussed and the model was constructed in the upflow process of the deep bed filtration. The effect of mass transport process and reaction processes on reaction kinetics was analyzed in the process of removal nitrogen by bio-denitrification. The result approve that the order of reaction of bio-denitrification kinetics was about 1/2～1 and accord with the constructed model basicaUy.2figs., 1tab., 9refs.
