Abstract: For the difficultly biodegradated organic dye wast ewater, the comparatively ideal experimental results were obtained using Zn- clays c atalysts for multi-catalytic ozonation process. The solid catalysts, made of cl ay carrier and carried Zn oxide, were used to treat the man-made dye wastewat er to raise the catalytic efficiency of ozonation and reduce the costs of trea tment. These solid catalyses can be used repeatedly.
