摘　　要：以纯TiO2、纳米TiO2、掺Fe3+及掺Fe的纳米TiO2为光催化剂,在暗室光催化反应器中进行了含阿奇霉素废水的光催化氧化降解性能研究。系统考察了光催化剂种类、光照时间、催化剂用量、掺Fe量等因素对降解过程的影响。结果表明,在pH=6.4、t=30min、催化剂用量为10g/L时,掺0.05%Fe的纳米TiO2降解效果最佳。Photocatalytic degradation of Azithromycion wastewater by TiO2, nanoscale TiO2, nanopaoticle Fe3+- TiO2 and nanopaoticle Fe- TiO2 was carried out in a dark photoreactor. Some important factors including catalyst category, reaction time, quantity of catalyst and Fe-doping were investigated, and results showed that the best photodegradation of nanoparicle 0.05%Fe- TiO2 is under the condition of pH 6.4, 30min and 10g/L.
