摘  要

光催化降解裝置作為反應的主體，它的性能決定了光催化反應效率，反應器的材料、結構、形狀等因素都決定了TiO2催化劑活性的發揮以及光的利用。光源的幾何位置以及TiO2催化劑的固定也對反應器的效率產生影響。
本文主要目的是對現有的光催化反應器性能進行研究，在原有的反應器基礎上設計具有多反射、加熱、內外循環功能的光催化反應器。同時詳細介紹多反射光催化水處理裝置的設計、制作和以濃度10mg/L 8-苯胺-α-萘磺酸為降解對象進行性能測試得出：在降解率達60%，原始裝置所用時間為6小時，而多反射光催化水處理裝置縮短至24分鐘。

關鍵詞： TiO2 催化劑，多反射，光催化反應器，性能

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.
