摘　　要：试验研究掺杂Fe和Ce 2种元素的改性TiO2光催化剂处理造纸废水的效果,并与未掺杂及单元素掺杂的TiO2光催化剂降解效果做了对比。试验结果表明:最佳反应条件下双元素掺杂的光催化剂对光的利用率最高,催化效果最好。原水样经过Fe和Ce双元素掺杂改性的TiO2光催化剂处理180 min后,脱色率在90%以上,CODCr去除率为83%,比未掺杂及单元素掺杂的催化剂活性有明显提高。Effect of modified TiO2 photocatalyst co-doped with Fe and Ce for treatment of paper mill wastewater was studied,and compared with effects of undoped and single element doped TiO2 photocatalysts.The experimental results indicate that under the best reaction condition,the light utilization rate of photocatalyst doped with dual elements is the highest and catalytic effect is the best.After being treated by modified TiO2 doped with dual elements Fe and Ce in 180 min,the raw water samples decolorization rate is more than 90%,CODCr removal rate is 83%,and the catalyst activity is significantly improved in comparation with the undoped and single element doped photocatalysts.
