Cu/ZnO composite oxide photocatalyst with different Cu amount was prepared by precipitation, and was used for photocatalytic degradation of molasses fermentation wastewater. The influences of Cu doping amount, catalyst dosage, pH of molasses fermentation wastewater and hydrogen peroxide dosage on the decolorization of molasses fermentation wastewater were investigated. The results show that the molasses fermentation wastewater was photocatalytic degradation by Cu/ZnO composite oxide photocatalyst effectively, when doped mole fraction of Cu was 2%, the photocatalytic activity of Cu/ZnO composite oxide photocatalyst is the best. When the 2% Cu/ZnO catalyst is 2.0 g/L, natural pH of wastewater, photocatalytic degradation for 150 min, the decolourization of molasses fermentation wastewater was 75.5%.
