In order to synthesis high efficiency catalyst to catalysis ozone oxidation pollutants in leachate, 75 kinds of Cu2+ and Ni2+ loading-ions catalysts were made with carrier γ-Al2O3 by dip method. The experimental results of the 75 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 impregnant concentration was 0.25 mol/L, mole ratio of Cu2+ and Ni2+ was 1, roasting temperature was 800℃. Metal ions mass loading-rate of this catalyst is 2.6764%. Characterization analysis for this catalysts indicates that loading-crystal by carrier are Cu2HIO6•2H2O and NiAl10O16.
