微波强化ClO2催化氧化处理活性艳黄染料废水

Experiments were conducted to investigate the removal of remazol golden yellow dye in order to assess the effectiveness and feasibility of microwave enhanced chlorine dioxide (ClO2) catalytic oxidation process. The results showed that microwave enhanced catalytic oxidation process could effectively degrade contaminants in short reaction time and with low oxidant dosage, extensive pH range. Under an optimal condition (ClO2 concentration 80 mg/L, microwave power 400 W, contact time 1.5 min, catalyst dosage 70g/L, pH=7), remazol golden yellow dye removal percentage approached 92.24%.Compared with different processes, microwave enhanced ClO2 catalytic oxidation system could significantly enhance the degradation efficiency. It provides an effective technology for the removal of remazol golden yellow dye wastewater.
