摘　　要：以 Ti O2 微粉及各种载体负载 Ti O2 为催化剂对含硝基苯酚废水进行光催化氧化实验。结果表明 ,活性炭负载 Ti O2溶胶型催化剂具有较高的光催化活性 ;当采用 30 0 W高压汞灯、催化剂质量分数为 0 .3%、p H值 =3.8、光催化降解 180 min时 ,对硝基苯酚水溶液的 COD去除率达 93%、工业含酚废水的 COD去除率为 80 %～ 83%。The photocatalytic oxidation of the phenol wastewater was carried out using TiO 2 microparticles and TiO 2 support materials.The experimental results showed that TiO 2 film immobilized on active carbon had a more efficient catalytic ability than other types of catalyst. The COD removal rates of p-nitrophenol water and industrial phenol wastewater were 93% and 80%～83% respectively under the conditions of pH value being 3.8,w(catalyst) 0.3%,the ultroviolet(UV) lamp 300W and degradation time 180 min.
