冠状病毒的生物学特性与紫外线对其消毒应用分析
|
Abstract:
冠状病毒是囊膜的单股正链RNA病毒，具有多种传播途径，对热、紫外线以及化学消毒剂均敏感。紫外线作为一种定向能物理消毒技术，传统的254 nm紫外线对细菌、病毒均具有良好的消毒性能；然而，新型222 nm远紫外线具有人机共存作用特点，对冠状病毒具有同样的杀灭性能，在未来疫情防控中具有广阔的应用前景。
Coronavirus were a kind of single strand and positive RNA virus with envelope. Their transmission routes might be diversified. Meanwhile, they usually were sensi-tive to heat, ultraviolet light and disinfectants. As a directed energy disinfection technology, the traditional ultraviolet disinfection technology with 254nm has a good disinfection ability to bacteria and viruses. However, compared with 254 nm, the far-ultraviolet with 222 nm has the same disin-fection ability to coronavirus. What’s important, the ultraviolet disinfection technology with 222 nm would carry out disinfection under the condition of man-machine coexistence. Therefore, the novel technology will have the broad application prospects in the future of epidemic prevention and con-trol.
