This paper reports the deep treatment of printing and dyeing waste water by heterogeneous photocatalyst WO3/CdS/W.The reaction mechanism of photocatalysis is probed.The relationships among the composition of heterogeneous photocatalyst, quantity, pH values, illumination time and the removal efficiency of COD and colority are discussed.The results show that the removal efficiency of COD and colority of printing and dyeing waste water can reach 69.8% and 71.0% by using WO3/CdS/W as heterogeneous photocatalyst, with the composition of m(WO3)/m(CdS)/m(W)=60∶39∶1, quantity0.300g, pH 6.5, illumination 10h.
