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%。
Taking glass fiber as the carrier, TiO2 was loaded on the surface to form a space glass fiber reactor, and Fe3 + was introduced as a doping modified ion to form a space glass fiber photocatalytic reactor loaded with TiO2 / Fe3 +. The high pressure mercury lamp The photocatalytic degradation of phenol in water was investigated by light source. The factors affecting the photocatalytic degradation of phenol were investigated. The results showed that under the irradiation of UV365 ~ 250 W light source, the pH value was 3 ~ 5 and the amount of O2 was 1.0 L / (min.L ), The rising rate of flow rate in the reactor was 0.7 m / min, the degradation rate of phenol wastewater with the initial concentration of 30 mg / L was up to 85% and the mineralization rate could reach 80% after 120 min photocatalytic reaction.
