摘　　要：研究了活性炭负载纳米TiO2的光催化降解性能和直接湖蓝废水处理的主要因素。结果表明:用活性炭负载TiO2具有催化效果好、可重复使用等优点;采用光强为4 050μW/cm2的紫外灯,处理100mg/L直接湖蓝废水的最优工艺条件是:废水pH值为1、光照时间为90min、载体粒径为35～55目。在此条件下,催化剂重复使用16次后对直接湖蓝的去除率为94%。TiOz films is deposited on the surface of activated carbon. The influences of conditions in immobilization and reaction on the catalyst are studied by its photo-degradtion of direct turquoise blue 5B . During the photo-catalystic oxidation process,the adequate reaction conditions were found as follows., the pH value is about 1, the time is 90 min, and the removal ratio of azithromycin is 94%.
