jaue2015067: Application of Cu2+ and Zn2+ Loading-Ions Catalysts for Leachate Treatment

Abstract

In order to synthesise high efficiency catalyst to catalysis ozone oxidation pollutants in leachate, 27 kinds of Cu2+ and Zn2+ loading-ions catalysts were made with carrier γ-Al2O3 by dip method. The experimental results of the 27 kinds of catalysts catalysis ozone oxidation pollutants in leachate indicate that the catalyst which can remove most COD and NH3-N of leachate was made on the conditions of impregnate concentration was the 0.05mol/L mole ratio of Cu2+ and Zn2+ was 2, roasting temperature was 600℃, and 0.10mol/L mole ratio of Cu2+ and Zn2+ was 4, roasting temperature was 800℃. Metal ions mass loading-rate of this catalyst is low. The catalyst for COD removal is 62.1% and 63.2%, respectively; NH3-N removal rate is 26.7% and 24.3%.
