| 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. |
