【摘要】 为了研究IC反应器处理猪场废水的运行规律,依据IC反应器中有机物降解特性,假设IC反应器精细处理区和污泥床区水力流态分别为推流和全混流、基质降解速率与微生物浓度之间符合一级反应模型,并在此基础上,建立了IC反应器处理猪场废水基质降解动力学理论模型,根据IC反应器处理猪场废水的试验结果,确定了平均温度为(33±0.5)℃条件下的动力学参数;然后对模型进行了验证,结果表明,理论预测值与实测值误差大多≤10%,二者吻合较好,证明该动力学模型可为IC反应器处理猪场废水的实际运行和数据预测提供科学依据。更多还原

【Abstract】 In order to work out the laws of piggery wastewater treatment in IC reactor, theoretic kinetics model of substrate decomposing in IC reactor was set up on the basis of analysis for substrate decomposing characteristics in IC reactor, and on the basis of the hypothesis: 1) fluid state in fine treatment section and sludge bed section is flow and plug flow, respectively, 2) the relationship between substrate decomposing and concentration of microbe coincides Class I reaction model. Based on the experimental results, the kinetics parameters of substrate decomposing under the average temperature of (33±0.5)℃ were determined. The validation of the kinetic model shows that most of the errors are no more than 8%, which demonstrates that the kinetics model can provide scientific bases for piggery wastewater treatment by using IC reactor.更多还原
