摘　　要：用光催化剂TiO2对西清河废水处理进行了研究。探讨了光催化反应机理,讨论了光催化剂的用量、试液的pH值、光照时间与COD、色度去除率的关系。实验结果表明:催化剂用量为0.600g、pH=6.5、光照12h,西清河废水的COD、色度去除率分别达到75.0%和78.5%。The wastewater from Xiqing river was treated by TiO2 as photocatalyst.The reaction mechanism of potocatalysis was probed into.The relationships between among the quantity of photocatalyst,pH values,illumination time and the removal rate of COD and colority of wastewater from Xiqing river were discussed.The experimental results indicated that the removal rate efficiencies of COD and colority of wastewater could reach to 75.0% and 78.5% respectivesly with quantity of photocatalyst=0.600g,pH=6.5,illumination time =8h .
