IC反应器处理柠檬酸废水宏观动力学研究

Study of Macro Kinetics About Citric Acid Wastewater with IC Reactor

依据IC反应器有机物降解特性的分析，对其第一反应区和第二反应区的水力流态分别作全混流和推流处理，以及其基质降解速率分别按零级反应和一级反应处理的基础上，建立了IC反应器宏观动力学理论模型。文中根据IC反应器处理柠檬酸废水的试验结果，确定了反应器在37℃条件下，其第一反应区和第二反应区内基质降解动力学系数分别为K1≈0.0576L／mg·VSS·h，K2≈0.2148h^-1，从而进一步确立了IC反应器处理柠檬酸废水的宏观动力学方程。并讨论了影响IC反应器处理效果的几项设计参数。

Based on the analysis of IC reactor characteristics of the degradation of organic matter, this article dealt with the first reaction zone and the second reaction zone＇s hydraulic fluid flow by way of full-flow and plug-flow respectively. At the same time, with zero and one reaction level as its matrix degradation rates , the thesis established the IC reactor kinetics model. From the experiment data of handling citric acid wastewater with IC reactor at 37℃, two substrate degradation kinetics coefficients were gained： the first reaction zone is K1≈0. 0576L/mg·VSS·h and the second is K2≈0.2148h^-1. From the result, the thesis further established the kinetics equation. The article also discussed a number of IC design pa- rameters which impacted the reactor＇s treatment efficiency.
