常温下高锰酸钾系催化剂处理含酚废水效果研究

The Effect of Phenol Wastewater Treatment with Potassium Permanganate Based Catalyst

采用浸渍法制备的高锰酸钾催化剂对含酚废水在常温下进行化学法处理,结果表明,单纯使用高锰酸钾为活性组分制备的催化剂对含酚废水的处理效果不明显,而加入铜离子后催化剂对含酚废水的降解率增加,同样c(Mn)∶c(Cu)=1∶3情况下,高浓度高锰酸钾催化剂对含酚废水的降解率高于低浓度高锰酸钾催化剂.

Phenolic wastewater was treated by chemical method using potassium permanganate catalysts prepared by impregnation method at normal temperature,and the results revealed that catalyst using potassium permanganate as the active component did not show the good performance in wastewater treating,while the catalyst adding copper ions made the decomposition rate of hydroxybenzene increase. Furthermore,catalyst containing high concentration of potassium permanganate led higher decomposition rate of phenolic wastewater than that containing low concentration of potassium permanganate at the same ratio of manganese to copper=1∶3 in molar fraction.
