随着人民生活水平的不断提高，创造仅仅具有适宜温度、湿度的舒适性空气环境已不能满足人们生活的需要，健康清洁的空气质量开始成为大众关注的热点。近年来，新型冠状病毒肆虐全球，气溶胶传播作为感染途径之一理应得到足够的重视。空气净化消毒技术对于防止细菌、病毒等病原体的扩散传播具有切实重要的意义。本文主要对多种物理类及化学类空气净化消毒技术进行详细的归纳介绍，分析这些技术在研究及应用中存在的问题，总结未来理想的空气净化消毒技术应当具备的特点。

With the continuous improvement of people’s living standards, simply creating a comfortable air environment with suitable temperature and humidity can no longer meet the needs of people’s lives. Healthy and clean air quality has begun to become a focus of public concern. In recent years, SARS-CoV-2 has been raging around the world, and aerosol transmission as one of the infection routes deserves sufficient attention. Air purification and disinfection technology is of great significance in preventing the spread of pathogens such as bacteria and viruses. This article mainly introduces a variety of physical and chemical air purification and disinfection technologies in detail, points out the problems existing in the research and application of these technologies, and finally proposes the characteristics that ideal air purification and disinfection technologies in the future should have.
