空气析解机除菌效果的实验观察

Effects of Air Disinfector: An Experimental Observation

目的了解空气析解机对室内空气中细菌与尘埃清除效果。方法连续开启空气析解机,并在不同时间,采用自然沉降菌与尘埃粒子(粒径为≥0.5μm与≥5.0μm两种粒子)来评价该机型对空气中细菌与尘埃的清除效果。结果连续20min,空气中的细菌清除率达到90.17%,小颗粒尘埃(粒径为≥0.5μm)清除率为29.43%,大颗粒尘埃(≥5.0μm)则为90.42%,至1h,细菌清除率基本不变,但小颗粒与大颗粒尘埃分别提高到52.63%和94.64%。结论该型空气析解机对清除空气中的细菌与尘埃具有一定的效果,建议规范使用空气消毒机。

OBJECTIVE To evaluate the effects of the air dislnfector in cleaning bacteria and dust in air. METHODS Turn on the machine, then place the plates and collect the dust（≥0. 5μm and ≥5.0μm particle） in different time, and evaluate the effects of the machine. RESULTS The elimination rate of the air bacteria, the small dust particle （≥0. 5μm） and the big one（≥5.0μm） was 90.17%, 29.43% and 90.42% at 20 min, respectively. But up to lh there were 90.17%, 52.63% and 94. 64%, respectively. CONCLUSIONS The air disinfector has a good efficacy in cleaning bacteria and dust particle, suggesting to use the machine by a regulatory way.
