The results show that the possible reasons of the catalyst deactivation are as follows : the suspended substances such as slightly soluble dyes in the wastewater and uncrystallized c produced in the potocatalytic reaction are adsorped on the surface of TiO2 ;some inorganic ions occupy the active center of photocatalyst, or precipitate on its surface ;the supported quantity of TiO2 decreases with long time use and repeated washing.

实验结果说明，催化剂活性下降的主要原因有：废水中不溶于水的染料等悬浮物和催化反应中产生的无定形碳在催化剂表面的吸附；高含量的无机离子对催化剂活性位的占据或在表面的沉积；长时间的使用和反复冲洗使TiO2负载量减少。
