摘要：

分别采用多级串联粒子电极和二维平板电催化、三维粒子电极电催化工艺处理初始COD为500 mg/L的苯酚溶液，对出水COD及电流效率进行测定分析。结果表明，保持相同吨水电耗和电流密度，二维平板电极、三维粒子电极、多级串联粒子电极出水COD分别为56、170、34 mg/L，去除率分别为88.8%、66.0%、93.2%。多级串联粒子电极吨水电耗、电流效率、反应速率优于二维平板电极和三维粒子电极，反应符合一级动力学。

Abstract:

The multi-stage series particle electrode technology, two-dimensional plate electrocatalysis and three-dimensional particle electrode electrocatalysis technology were used to treat phenol solution whose initial COD was 500 mg/L respectively. The COD and current efficiency of effluent were analyzed. The results showed that when maintained the same electricity consumption per ton water and current density, the two-dimensional plate electrode reactor, the three-dimensional plate electrode reactor and the multi-stage series particle electrode reactor's effluent COD respectively were 56, 170, 34 mg/L, and the removal rate respectively were 88.8%, 66.0%, 93.2%. The electricity consumption per ton water, current efficiency and reaction rate of multi-stage series particle electrode reactor are better than the other two technologies. The reaction follows the first order kinetics.
