摘　　要：用复相光催化剂 WO3 /Cd S/W对印染废水的深度处理进行了研究。探讨了光催化反应机理 ,讨论了复相光催化剂的组成、用量、试液 p H值、光照时间与 COD、色度去除率的关系。实验结果表明 :以 WO3 /Cd S/W为复相光催化剂 ,其组成为 WO3 /Cd S/W=60∶ 39∶ 1、用量 =0 .30 0 g、试液 p H=6.5、光照 1 0 h,印染废水的 COD、色度去除率分别达到 69.8%和 71 .0 %。This paper reports the depth treatment of printing and dyeing wastewater by heterogeneous photocatalyst WO 3/CdS/W. Reaction mechanism of photocatalysis is probed. These relationships between the composition of heterogeneous photocatalyst, quanity,pH values, illumination time and the removal efficiencies of COD and colority are discussed. The results show that the removal efficiencies of COD and colority of printing and dyeing wastewater can reach 69.8% and 71.0% by using WO 3/CdS/W as heterogeneous photocatalyst, with the composition of WO 3/CdS/W=60∶39∶1, quantity=0.300g,pH=6.5, illumination 10h?
