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。

The results show that proper control of additive, flocculating agent, temperature, stir speed, quantity of each agent and other process parameters could effectively remove the impurities in the coagulation bath such as the solid, big molecules in the forms of undissolved colloid and semi-colloid. The sizes of flocculates are big and loose, ready to precipitate, therefore the impurity removing effect is very ideal, greatly improving the exchange ability of the ion exchange resin in the subsequent process.

研究结果表明在选用合适的添加剂与絮凝剂，适当控制絮凝的温度、搅拌速度、各试剂的添加量和添加顺序等相关工艺参数的条件下，凝固浴中的絮状固体杂质、以未溶解的胶态和半胶态形式存在的大分子性杂质等都被去除，絮凝物块大而疏松，沉降迅速，除杂纯化效果非常理想，大大提高了后续处理工艺中阴阳离子交换树脂的处理能力。
