电催化氧化法处理染料废水的影响因素及动力学
Affecting factors and kinetics of dye wastewater treatment by electro-catalytic oxidation process
摘要
Abstract
Under the condition of the coating of titanium plate as anode, graphite plate as cathode and Fe203/y-Al2O3 as heterogeneous catalyst, COD removal effect and its affecting factors in dye-wastewater of acid red by electro-heterogeneous catalytic oxidation system were investigated. Experimental conditions and the degra- dation mechanism of COD were discussed. The result shows that cell voltage, pH, airflow rate and electrode dis- tance had a significant impact on COD removal. The best COD removal was 64.5% with cell voltage of 20 V, pH of 4, airflow rate of 0.24 m3/h and electrode distance of 3 cm. The degradation of COD approximation order kinetics equation: In(C0/C) =0. 0034t + 0. 719. It is capable of mineralizing organic contaminants into H2O, CO2 and other inorganics in the electro-heterogeneous catalytic oxidation system.关键词
