环境治理技术与光催化组合工艺的研究及应用

Research on the combined process and its application of environmental control technology and photocatalytic

光催化氧化技术具有反应条件温和、无二次污染等优点,被认为是一项新型的水处理技术。但其在实际应用中存在低效率、难回收等缺陷,而光催化技术与其他环境治理技术的联合工艺期望可以克服这些缺陷。论述了光催化氧化技术与传统环境治理技术(膜分离、氧化法、生物法),与高级氧化技术(超声、电化学、Fenton)以及与其他环境治理技术组合工艺处理多种废水的研究,并对其反应机理及应用进行了总结。

The photocatalytic oxidation technology which has the advantages of mild reaction conditions and no secondary pollution has been considered to be a new type of water treatment technology.However,there exist some defects in practical application,such as low efficiency and difficult to recover,while the combination of photocatalytic technology and other environmental control technologies can solve these problems.Researches on the combined processes of photocatalytic oxidation technology and traditional environment control technologies（membrane separation,oxidation,biological method）,the other advanced oxidation technologies（ultrasound,electrochemistry,Fenton）,as well as the other environmental technologies,for treating various wastewater are discussed.In addition,their reaction mechanisms and application are summarized.
