摘　　要：针对饮用水进行深度处理提出紫外光激发催化氧化（ＵＶ／ＴｉＯ２／Ｈ２Ｏ２）工艺，研究表明：①ＵＶ／ＴｉＯ２／Ｈ２Ｏ２工艺能有效去除水中的ＣＨＣｌ３；②ＣＨＣｌ３的光氧化降解遵循一级动力学反应规律。Photoexcited combined with photocatalytic oxidation technology (UV/TiO 2/H 2O 2)was studied for advanced treatment of drinking water. The results showed that the process was offective in removing CHCL 3 from drinking water and the degradation of CHCL 3 followed the first order reaction kinetics. The reaction rate constant was related to the dosage of hydrogen peroxide and the intensity of ultraviolet irradiation.
