摘 要
光催化降解装置作为反应的主体，它的性能决定了光催化反应效率，反应器的材料、结构、形状等因素都决定了TiO2催化剂活性的发挥以及光的利用。光源的几何位置以及TiO2催化剂的固定也对反应器的效率产生影响。
本文主要目的是对现有的光催化反应器性能进行研究，在原有的反应器基础上设计具有多反射、加热、内外循环功能的光催化反应器。同时详细介绍多反射光催化水处理装置的设计、制作和以浓度10mg/L 8-苯胺-α-萘磺酸为降解对象进行性能测试得出：在降解率达60%，原始装置所用时间为6小时，而多反射光催化水处理装置缩短至24分钟。

ABSTRACT
As photocatalytic degradation equipment is regarded as the main body, photocatalytic rate, matercals, structure, shape of the reaction vessel and so on are decided by its function. Furthermore, there factions determine the development of TiO2 catalyst and the use of light. Meanwhile, influence on the efficient of vessels.
In this paper, it is studied the resent function of photocatalytic reaction vessels and is aiming to design the one with the function of light-reflection, heating and inside-outside cycling. at the same time, this paper introduces detailedly the design and manufacture of multi-reflection photocatalytic water-treatment equipment and degrading 8-anilina-α-naphthalene-sulfonic acid with this equipment to teas its function. By the means of this testing, we can get that when the degrading efficiency is up to 60 percent, using the original equipment, the degrading times is 6 hours. But it using the multi-reflection photocatalytic water-treatment equipment, the degrading time is reduced to 24 minutes.
