Class fiber used as carrier, TiO2/Fe3+ has been loaded to its surfacee,forming the space glass fiber reactor. Using high pressure mercury lamp as its light source,so as to carry out the experimental research on the degradation of phenol in water. The influences of the synergistic effect of H2O2 and O2 on photo-catalysis oxidation are investigated emphatically. It is found through experiments that adding H2O2 has remarkable initiation effect on the production of HO? ,and oxygenizing to the solution can obviously improve the efficiency of photo-catalysis and reduce H2O2 dosage. The results show that the phenol mineralization rate can reach about 83% ,when the power of UV365 high pressure mercury lamp is 250 W,pH 3-5,O2 inlet quantity 1.0 L/(min?L),H2O2 dosage 0.1 mmol/L, rising flow rate in the reactor 0.7 m/min, initial mass concentration of phenol wastewater 30 mg/L,and photo-catalystic reaction time 120 min.%以玻璃纤维为载体,将TiO2/Fe3+负载到其表面制成了空间玻璃纤维反应器.利用该反应器以高压汞灯为光源进行了光催化降解水中苯酚的试验研究,重点考察了H2O2及O2的协同作用对光催化氧化的影响.试验发现,H2O2的加入对HO·的产生有显著的引发作用,同时向溶液中充入O2可明显提高光催化效率,降低H2O2用量.试验结果表明,以UV365-250W光源照射,在初始pH为3～5,O2通入量为1.0L/(min·L),上升流速为0.7 m/min,H2O2浓度为0.1mmol/L等试验条件下,初始质量浓度为30mgL的苯酚废水经120 min光催化反应后,其矿化率可达83％左右.
