摘要
Abstract
The copper-manganese oxide catalysts supported on acid modified attapulgite (ATP) and activated carbon were prepared by a method of impregnation.The COD and color of dyeing wastewater secondary effluent were chosen as the treated object.The effects of the proportion of ATP and activated carbon,pH values as well as the dosage of H2O2 and the catalyst on the elimination efficiency of treated object were investigated.The structural properties of catalysts were characterized by SEM and XRD.The results showed that the COD and color reached the best removal efficiency which were 93% and 90%,respectively,when the temperature was 25 ℃,the ratio of ATP and activated carbon of 2∶1,the amount of H2O2,two times of the theoretical amount,pH of 4,and catalyst dosage of 15 g · L-1 The copper and manganese oxides were dispersed on the surface of the catalysts in the form of nano particles and the active components were CuO and MnO2.关键词
