气载致病微生物和空气消毒技术

Airborne Pathogenic Microorganisms and Air Disinfection Technologies

近年来全球频繁暴发通过空气传播的传染疾病,造成疫情的大范围传播,给人类健康带来严重威胁。空气中的病毒和细菌属于气载微生物,可以在空气中存活并进行传播。这种传播方式相较于水、土壤等其他媒介的传播,具有传播速度快、影响范围广的特点,极易引起社会恐慌。介绍了气载致病微生物及其危害,阐明了气载致病微生物的存在形式和传播途径,归纳总结了国内外在空气微生物控制方面的相关标准,并系统介绍了各类空气消毒技术和净化设备的特点和应用情况。

In recent years,frequent outbreaks of air borne infectious diseases have caused widespread transmission of the epidemic and brought serious threats to human health.Airborne viruses and bacteria are airborne microorganisms that can survive and spread in the air.Compared with other media,such as water and soil,this type of transmission has the characteristics of rapid transmission and wide influence,and it is easy to cause social panic.This paper introduced the characteristics,harm and the transmission routes and ways of airborne pathogenic microorganisms,summarized the relevant standards of air microorganism control at home and abroad.Furthermore,the characteristics and application of various air disinfection techniques and purification equipment were illustrated as well.
