摘要: 以玻璃纤维为载体，将TiO2负载到其表面形成了空间玻璃纤维反应器，引入Fe3+作为掺杂改性离子，形成了负载TiO2/Fe3+的空间玻璃纤维光催化反应器，并以高压汞灯为光源进行了光催化降解水中苯酚的实验研究，考察了影响苯酚光催化降解的因素，确定了在UV365～250 W光源照射下，pH为3～5，O2通入量1.0 L/(min?L)，反应器内上升流速为0.7 m/min等实验条件下，初始浓度为30 mg/L的苯酚废水经120 min光催化反应后，降解率可达到85%，矿化率可达80%。

Abstract: TiO2/Fe3+/glass fiber was prepared with TiO2 and Fe3+ coated on glass fiber， and Fe3+ was doped as a modification ion. The photocatalytic activity of TiO2/Fe3+/glass fiber was evaluated using phenol as a model substrate. The experimental results demonstrated that TiO2/Fe3+ coated on glass fiber had good degradeation capacity. The optimum conditions evaluated by degradation and mineralization rates of phenol were as follows: wastewater pH of 3～5， O2 of 1.0 L/(min?L)， rising velocity of 0.7 m/min， and power of 365 UV high-presser mercury lamp was 250 W. Under the optimum conditions， phenol degradation and mineralization rates could reach 85% and 80%， respectively when initial phenol concentration was 30 mg/L and reaction time lasted 120 min.
