UV advanced oxidation reactors for water treatment

供水中有毒有机化合物的存在在加拿大和世界各地引起了极大的环境关注。这些污染物中的大部分可以被光引发的氧化(通过紫外线-UV辐射激活强氧化剂，如过氧化氢，形成氧化性的羟基自由基)或光催化氧化(通过光催化反应形成羟基自由基)完全摧毁。尽管在过去的几年里，紫外光引发和光催化氧化过程有了相当大的研究和商业兴趣，但对这些技术的过程模拟和优化知之甚少。因此，它们在水处理方面的工业应用一直受到限制，商业系统总体上只取得了部分成功。

The presence of toxic organic compounds in water supplies is of great environmental concern in Canada and around the world. The majority of these contaminants can be destroyed completely by photo-initiated oxidation (activation of strong oxidants such as hydrogen peroxide by ultraviolet -UV- radiation to form oxidative hydroxyl radicals) or photocatalytic oxidation (formation of hydroxyl radicals through photocatalytic reactions). Despite considerable research and commercial interests in UV photo-initiated and photocatalytic oxidation processes in the past few years, little is known about the process simulation and optimization of these technologies. As a result, their industrial application to water treatment has been limited and commercial systems, in general, have met with only partial success.
