  • 摘要: 在转盘式光电液膜反应器(RPEC)反应动力学方程的基础上,综合考虑外加偏压(0—0.4 V)、转盘转速(0—90 r·min-1)、初始浓度(0—100 mg·L-1)、转盘半径(37.5 mm)等因素对反应过程的影响,运用MATLAB软件对转盘转动的反应过程进行模拟计算和推测.计算结果与实验数据能较好吻合,数据误差在10%以内.从而建立了一种不同条件下转盘式光电催化降解废水的降解模型,对实际工业应用具有一定的预测与指导意义.
    Abstract: In this article, based on the rotating photoelectrocatalytic reactor kinetic equation and considering the influence factors including, bias voltage(0—0.4 V), wheel speed(0—90 r·min-1), initial concentration (10—100 mg·L-1) and wheel radius (37.5 mm), the aim of this work is to set up the degradation model by using iterative calculation in MATLAB software to simulate the rotating process. It proved that the degradation curves match the experiments coincidently with the data error in 10% and provide the guidance for the practical industry applications.
