摘要
介绍了UV/氯工艺的反应机理,在此基础上着重介绍UV波长、自由氯浓度、pH以及水中背景物质对该工艺的影响,并阐述了水中污染物的降解机理。同时,对目前该技术的发展现状和现存问题以及发展方向做了总结与展望。
In this paper,the reaction mechanism of UV/chlorine process is fully discussed and the effects of UV wavelength,concentration of free chlorine,pH value and background substances in water on the process are introduced.The degradation mechanism of pollutants in water is described.Finally,the current status,challenges and future directions are also summarized.
