摘　　要：为了观察静电空气净化消毒器对医院室内空气消毒效果,采用平板沉降法采样,对其进行了实验观察并与紫外线作平行比较。结果,经静电空气净化消毒器开机30min后和30W紫外线灯照射60min,均可使空气中自然菌下降率达到88.83％;但室内有人工作的情况下,该空气净化消毒器持续运行可使空气中细菌总数保持在200cfu/m^3以下,符合医院Ⅱ类环境卫生标准,而紫外线则不能。结果显示,静电空气净化消毒器用于医院室内空气消毒,可以在有人条件下持续运行,能保持空气中细菌总数在200cfu/m^3以下。In order to observe the efficacy of Electrostatic Air Purifying Disinfector in disinfection of indoor air of hospital, experimental observation and parallel comparison with ultraviolet radiation were carried out.The results showed that operation of the Electrostatic Air Purifying Disinfector for 30 min and 30 W ultraviolet lamp irradiation for 60 min could reduce the natural bacteria in air by 88.83%. However, continuous operation of the Air Purifying Disinfector in occupied room could keep the total bacterial count in air below 200 cfu / m^3, which meets class-Ⅱ environmental sanitary standard of hospital, while the ultraviolet radiation could not. The results indicated that when the Electrostatic Air Purifying Disinfector is used for indoor air disinfection in hospital, it can operate continuously in occupied room and keep the total bacterial count in air below 200 cfu / m^3.
