【摘要】 为了观察新研制的高电压空气消毒机对室内空气洁净效果,用P-5型数字粉尘仪和全玻璃液体冲击采样器采样,对该消毒器降尘和消除微生物效果进行了检测。结果,在温度为14～16℃,相对湿度为55％～60％的条件下,开机15、30、60min对空气中金黄色葡萄球菌的消除率分别为99.93％、99.95％和 99.99％; 开机15、30、60和90min对空气中枯草杆菌黑色变种芽孢的消除率分别为98.87％、99.50％、99.72％和99.84％;开机74min,除尘率达57.96％。结果表明,该消毒器对室内空气中细菌和尘粒均有一定的消除效果。更多还原

【Abstract】 In order to observe the efficacy of a newly developed high voltage air disinfector in purifying indoor air, P-5-type digital dust meter and sampling of air with a full-glass liquid impingement sampler were used for examining the efficacy of this disinfector in reducing dust and eliminating microorganisms. The results showed that at temperature of 14- 16℃and relative humidity of 55%- 60%, operation of the disinfector for 15, 30 and 60 min could eliminate 99.93%, 99.95% -and 99.99% of Staphylococcus aureus in air respectively, operation for 15, 30, 60 and 90 min could eliminate 98.87%, 99.50%, 99.72% and 99.84% of spores of Bacillus subtilis var. niger in air respectively, and operation for 74 min could remove 57.96% of dust. The results indicate that the disinfector has certain efficacy in eliminating bacteria and dust in indoor air.更多还原
