摘　　要：在COVID-19流行期,为考察新型紫外线消毒技术研究及其应用状况,对紫外发光二极管和222nm远紫外消毒技术两类新型紫外消毒技术进行了探讨。详细介绍了UV-LED的单波长照射,脉冲紫外照射和多波长协同照射三种消毒方案的研究进展、应用场所并对其潜力进行了探讨;重点介绍了222nm远紫外消毒技术,对其应用和未来发展做出了展望;讨论了UV-LED现阶段遇到的问题并对紫外消毒市场发展做出了展望,预计未来紫外消毒市场中将形成汞灯为主,LED为辅,两者相互补充的格局。In the covid-19 epidemic period, in order to investigate the research and application of various ultraviolet disinfection technologies, low-pressure mercury lamp and ultraviolet light-emitting diode( UV-LED) as the mainstream ultraviolet disinfection light sources in the market are investigated. The principle, application and main characteristics of the two light sources are briefly introduced and the research progress, application sites and potential of UV-LED single wavelength irradiation, pulsed irradiation and multi-wavelength synergistic irradiation are introduced and evaluated. The 222 nm safety ultraviolet disinfection technology was introduced and its application was prospected. Finally, the problems of UV-LED at the present stage are discussed and the prospect of the development of UV-LED disinfection market is presented. It is expected that the future UV disinfection market will form mercury lamp, LED as a supplement, the two complementary pattern.
