摘要

采用钴锰尖晶石作为催化剂,以对苯二甲酸废水为研究对象,采用臭氧协同催化氧化降解方法,对含对苯二甲酸废水进行了实验研究,利用单因素实验筛选出催化反应的最佳条件。实验结果表明:在钴锰尖晶石投加量为20 mg,臭氧通入量为50.5 mg/min,对苯二甲酸废水pH值为10时,处理效果最佳,并在此最佳条件下对钴锰尖晶石的催化活性及重复利用性进行了评价。
        With cobalt-manganese spinel as catalyst,the ozone-assisted catalytic oxidation degradation of terephthalic acid wastewater was studied experimentally. The best conditions for the catalytic reaction were screened by single factor experiment. The experimental results show when the cobalt-manganese spinel is 20 mg, the ozone input is 50.5 mg/min,and the pH value of the terephthalic acid wastewater is 10, the treatment effect for the wastewater is the best. Under the optimal conditions, the catalytic activity and recyclability of the cobalt-manganese were evaluated.
