含酚废水电化学处理动力学研究

Chemical Kinetics Study on Phenolic Wastewater Treatment by Electro-Catalysis Oxidation

以实验研究为基础,探讨了含酚废水电化学处理的动力学规律,分析了曝气量、电解电压和支持电解质浓度对反应速率的影响。研究表明:污染物的电解氧化反应过程符合表观一级反应动力学规律,电解电压对电化学处理反应速率影响较大,而曝气量和支持电解质浓度对反应速率影响相对很小。

Based on experimental research,the kinetics law of phenolic wastewater treatment by electro-catalysis oxidation was discussed.Influence of aeration rate,electrolytic voltage and support electrolytes concentration on reaction rate was analyzed.The results show that the electrochemical degradation accords with the apparent first-order kinetics law,and the electrolytic voltage has greater impact on electrochemical treatment reaction rate,but effects of aeration rate and support electrolytes concentration on electrochemical reaction rate are relatively small.
