| 摘 要： | 为了解循环风紫外线动态空气消毒机的消毒效果和臭氧含量,用臭氧测定仪和载体定量法及平皿沉降法进行检测。结果,开机后60min测不到臭氧,对玻片上金黄色葡萄球菌和枯草杆菌黑色变种芽孢开机作用120min,平均杀灭率达到99.9％;对室内空气自然菌,作用120min平均消亡率达到95％以上。结果表明,该循环风消毒器具有良好的杀菌效果,对室内空气自然菌可达到消毒要求。

| Abstract: | In order to know the disinfection efficacy and ozone content of Circulating Air Ultraviolet Air Disinfector, ozone detector, carrier quantitative method and disk sedimentation method were used for examination. The results showed that ozone was not detected after the Disinfector operated for 60 min. The average killing rate of Staphylococcus aureus and spores of Bacillus subtilis var. niger on glass slide attained 99.9% after exposure to the operating Disinfector for 120 min and the average decay rate of the natural bacteria in indoor air attained over 95% after exposure for 120 min. The results indicated that this Circulating Air Disinfector has good germicidal efficacy and can fulfill the requirement of disinfection of the natural bacteria in indoor air. |
