摘要
紫外线照射技术可提高室内空气质量,控制管道内微生物污染。本文对紫外线杀灭空气微生物的原理(DNA损伤、脂质变化和蛋白质损伤)、影响管道内紫外线去除微生物效果的因素、管道内紫外线强度分布计算模型,以及紫外线杀灭微生物理论模型进行综述,并对紫外线照射去除管道内空气微生物的未来研究方向进行展望。
Ultraviolet(UV)irradiation technology can improve indoor air quality and control microbial contamination in pipelines.This article reviews the mechanism of UV irradiation for killing airborne microorganisms(DNA damage,lipid changes and protein damage),factors affecting the effectiveness of UV removal of microorganisms inside pipelines,calculation models of UV intensity distribution inside pipelines,and theoretical models of UV in killing microorganisms.It also provides an outlook on the future research direction of UV irradiation for removing air-borne microorganisms in pipelines.
