摘要
试验研究采用钨化合物、TiO2粉未催化剂对活性绿染料废水的光催化降解，通过测定废水中的COD值确定废水降解程度。结果表明催化剂的催化活性顺序为：活性白钨酸＞新制TiO2＞蓝色氧化钨＞黄钨酸＞久置TiO2＞WO3。其活性不仅取决于催化剂本身的性质，而且与其制备方法有关。此外，还对光催化过程中COD值随时间的变化规律进行了探讨。
In this paper,photocatalytic degradation is suggested to treat waste water from activechlorine dye. Many photocatalysts and the influential factors on the removal ratio of COD arediscussed. It is shown that the photochemical catalysis of the catalysts decrease in the sequence: white powdery tengstic oxide hydrate＞TiO2 (virgin material) ＞blue tungsten trioxide＞H2WO4 (yellow)＞TiO2＞WO3. The COD concentration of the treated water will be upto national standards of discharge.
