摘要
阐述了微生物在空气中的传播机理,介绍了通风换气、空气过滤及紫外线杀菌三种控制方法,采用Wells-Riley方程分析了通风换气对降低感染率的影响,给出了一些常见空气过滤器的滤菌效率,分析了紫外线照射用于流动空气杀菌的局限性。
Analyses the transmission mechanism of airborne microbes. Presents three commonly used engineering control methods, including ventilation, air filtration and ultraviolet germicidul irradiation (UVGI), discusses the relationship between ventilation rate and infection rate based on the Wells-Riley equation, gives the filtration efficiency of some air filters for bacteria, and analyses the limitation of UVGI for airstream. especially for in-duct irradiation.
