摘　　要：由于各类化学品的大量生产和使用,近年来水循环系统中频繁检出各种新污染物,迫切需要研究对于新污染物的新型处理技术。在众多去除新污染物的方法中,基于UV的高级氧化技术因去除效果好,效率高而备受关注,但目前常用的254,365 nm等传统波长紫外线可能会对人体造成伤害。在新冠疫情期间用于灭菌和消毒的222 nm紫外线因对于人体伤害性小,且其去除污染物的效率高于传统波长紫外线而引起越来越多的关注。对新污染物的存在现状以及目前存在的不同波长紫外技术在各领域的应用现状进行了总结,讨论了不同波长下UV/H_(2)O_(2)、UV/PS和UV/氯体系下对新污染物的去除效果,总的来看使用UV222去除水中的新污染物拥有较好的前景。Due to the mass production and use of various chemicals,various new pollutants have been frequently detected in the water cycle system in recent years,and there is an urgent need to study new treatment technologies for new pollutants.Among the many methods to remove new pollutants,advanced UV-based oxidation technology has attracted much attention due to its good removal effect and high efficiency,but the traditional wavelength ultraviolet rays such as 254,365 nm that are commonly used at present may cause harm to the human body.The 222 nm ultraviolet light used for sterilization and disinfection during the coronavirus pandemic has attracted increasing attention because it is less harmful to humans and is more efficient at removing contaminants than traditional wavelength ultraviolet light.The existence of new pollutants and the application status of UV technology with different wavelengths in various fields are summarized,and the removal effects of UV/H_(2)O_(2),UV/PS and UV/chlorine systems at different wavelengths are discussed.
