摘要: 依据对IC反应器有机物降解特性的分析,以及对其精细处理区和污泥床区水力流态分别作推流和全混流处理,基质降解速率与微生物浓度之间按一级反应处理的基础上,建立了IC反应器基质降解动力学理论模型。并根据IC反应器处理养猪场污水的试验结果,确定出了反应器在平均温度为(33±0.5)℃条件下污泥床区和精细处理区内基质降解动力学模型。Abstract: Theory model of kinetics of substrate decomposing in reactor was set up on the basis of analysis for substrate decomposing characteristics in reactor, and on the basis of the hypothesis: the flow and plug flow, and the relationship between substrate decomposing was conducted in IC reactor on treating piggery wastewater. By the experiment the kinetic coefficients of substrate decomposing in expanded granular sludge bed and fine treatment bed were determined under(33±0.5)℃.
