活性炭多维电极法处理活性染料模拟废水的机理研究

Study on mechanism of treatment of simulated wastewater containing reactive dye with multi-dimensional active-carbon electrodes

以活性嫩黄K-4G染料模拟废水为处理对象,探讨了多维电极系统处理活性染料废水时色度、COD降解的效果和机理。结果表明,活性炭多维电极法对染料废水的处理效果优于单纯电解法和单纯活性炭吸附法;氧化和还原作用对染料的色度和COD去除效果相差不大;增大处理系统中溶液的循环流量可显著改善活性炭多维电极系统对COD和色度的去除效果。

Simulated wastewater of reactive light-yellow K-4G dyes was treated by multi-electrodes method. The effect and mechanism of decoloration and removal of COD were discussed. The result showed that the treating effects of multi-electrodes method of activated carbon was better than that of adsorption method of activated carbon and that of the electrolytic method ;the effects of decoloration and removal of COD of oxidation and reduction were alike; the effect of decoloration and removal of COD was improved when the circulating flux was increased.
