摘　　要：用自制的光催化反应器,以天然斜发沸石负载TiO2为光催化剂,紫外光为光源,对制药工业废水进行光催化降解实验,研究其在不同条件下的光催化降解效果。实验结果表明,经过光催化降解反应,制药工业废水的COD去除率可达78.2%,脱色率为94.6%。Taking the TiO2 supported on natural elinuptilolite as photocatalyst, the ultraviolet light as light source, the photocatalytic degradation of pharmaceutical wastewater was studied with self-made photocatalytic reactor, and the degradation effects nnder different conditions were investigated. The results showed that the COD removal rate of the pharmaceutical wastewater achieved 78.2%, and the decolorization rate was 94.6%.
