【摘要】 建立了三维电极对染料废水电催化氧化的电流效率计算模型,研究了电催化氧化染料废水过程中电流效率的变化规律,探讨了染料废水初始浓度与电流效率的关系。结果表明,三维电极体系的电流效率远高于二维电极;瞬时电流效率随过程的进行而下降;废水的初始浓度越高,电流效率越高,且初始浓度越高,瞬时电流效率下降的速率也越快;平均电流效率与初始浓度存在着明确的函数关系;本研究为高浓度染料废水的处理提供了新的思路。更多还原

【Abstract】 Current efficiency computing models of electrocatalytic oxidation of dye wastewater in three dimensional electrode were built. The variation of current efficiency and the relationship between current efficiency and initial concentration of dye wastewater were discussed. The results show that current efficiency of three dimensional electrode is much higher than that of two dimensional electrode; the instant current efficiency declines with the process of electrocatalytic oxidation; the higher the initial concentration is,the higher the current efficiency will be,and the faster the instant current efficiency will decline; there is a functional relationship between the average current efficiency and initial concentration; the research proposes a new idea about the treatment of high concentration dye waste water.更多还原
