采用石墨电极对含α-氯代环己基苯基甲酮的氯化清洗水进行电化学降解。结果表明,电化学降解对COD的去除效果非常明显,并且随着电流密度增加,COD的去除效率逐渐升高,电流密度由15 mA/cm2增加至100 mA/cm2, COD的去除率从39.7%升高到72.3%；电化学降解作用下,水样可生化性显著提高,降解2 h后,(BOD5)/(COD)由原水的0.22提高到0.46；电化学降解过程中,COD的降解遵循零级反应动力学方程；此外,还对电化学降解过程中α-氯代环己基苯基甲酮的降解途径进行了推测。

The electrochemical degradation ofα-chlorinated cyclohexyl phenyl ketone by graphite electrodes was conducted in this paper. The results showed that COD removal efficiency were obvious, and the COD removal efficiency increased with the augment of current density, the current density increased from 15 mA/cm2 to 100 mA/cm2, the COD removal efficiency achieved from 39.7% to 72.3%, correspondingly. The biochemical properties improved under the action of electrochemical degradation, after 2h, the numerical value of BOD5/COD achieved 0.46 which was 0.22 originally. The degradation of COD followed zero order kinetics. Moreover, the degradation pathway of chlorinated cyclohexyl phenyl ketone was speculated in electrochemical degradation system.
