混凝和氧化法相结合对印染废水脱色处理的研究

Study of Decoloration of Dyeing Wastewater by Coagulation and Oxidation Method

采用混凝和氧化相结合的方法对色度较高的含有碱性品红的印染废水进行了脱色处理,研究了工艺条件对脱色效果的影响,确定了最佳工艺条件。废水脱色率可达95%,COD去除率可达80%以上,该方法工艺简单、效果良好。

The fuchsine-containing dyeing wastewater with high colority was decolored by coagulation and oxidation method. The effect of technological conditions on decoloration effect was discussed, the optimum conditions were determined. The results show that, under the optimum conditions, the decoloration rate can reach to 95%, the removal rate of chemical oxygen demand is more than 80%, and the method is simple and its effect is good.
