摘要
目的:研究OM-500型臭氧空气消毒杀菌机的杀菌效果。方法:采用载体定量表面杀菌试验及现场空气消毒试验两种方法观察臭氧作用不同时间对物体表面细菌及空气中细菌的杀灭效果。结果:用载体定量表面消毒杀菌试验,对金黄色葡萄球菌杀灭率60min达94·41%;对大肠杆菌杀灭率5min达97·3%,60min达100%;用现场空气消毒试验法,空气中自然菌减少率30min可达90·88%,60min达到95·74%,120min达到99·03%。结论:本机型消毒效果良好。
Objective： To study the air disinfection effect of Om - 500 ozone air disinfector using two methods. Methods： When carrier quantitative test was used, we found that 94.41% of Staphylococcus aureus and 100% of E. coli was killed if Om- 500 ozone air disinfector for 60 min, and 97.3% of E. coli was killed if operated for 5 min. When simulate locale air disinfection test was used, the result shows that decrease rate of nature bacterium in air can reach to 90.88 % and 95.74 % respectively. Conclusion： The experiment suggested that it has a good air disintection effect.
