摘要
研究了高压脉冲电流对几类典型染料废水的处理效果。试验结果表明 :高压脉冲电流可以有效地破坏试品中染料分子的发色基团 ,脱色效果明显 ;处理后的试品 ,包含沉淀废水的化学需氧量 (COD)值明显升高 ,所以需要利用金属氢氧化物的絮凝作用来最终降低试品的COD值 ;
Nearly 20 different kinds of dyeing wastewater are treated using high voltage pulse. The experimental results show that the pulse current can effectively destroy the chromophoric group of the dye; the amount of the Chemical Oxygen Demand (COD) of samples during the treatment goes up obviously, so it is necessary to utilize the hydrates of the metal to finally reduce the amount of the COD of samples; the effectiveness of this treatment on different dyeing wastewater is influenced strongly by the shapes of the electrodes.
