电催化氧化处理印染废水的实验教学设计

Experimental Teaching Design of Treating Dyeing Wastewater by Electrocatalytic Oxidation

为实现实验教学与科研工作的紧密结合,该实验教学设计采用电催化氧化技术对印染废水进行处理。构建脉冲电催化氧化处理印染废水反应体系,设定不同反应条件,探索废水初始浓度、初始pH、电解质的浓度、电压及脉冲频率等实验条件对废水降解效果的影响,并分析其影响的主要原因。使学生更好地理解和掌握电催化氧化技术处理印染废水的基本原理、操作步骤及结果分析方法。

To combine the experimental teaching with scientific research tightly,an experiment was designed to treat dyeing wastewater by electrocatalytic oxidation.A pulsed electrocatalytic oxidation equipment for the dyeing wastewater was constructed.The experimental conditions effects of the degradation of dyeing wastewater,such as the initial concentration,initial pH value of wastewater,concentration of the electrolyte,voltage of pulse and the frequency of pulse,were elucidated respectively.And the main reasons for its impact were analyzed.It provided students with better understanding and mastering of the detection principle,the operation procedure and the analysis method.
