摘要: 对于生物难降解性有机染料废水,用矿物催化剂进行复合催化氧化获 得了比较理想 的实验处理效果。以粘土为载体加载金属锌氧化物制成的可重复使用的固体催化剂,对人工模拟的染料废水进行复合催化臭氧氧化实验,获得了满意的效果。该法进一步提高了臭氧的降解效果,降低了处理成本。

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.
