【摘要】 目的 研究一种新型复合式空气消毒机的消毒效果和安全性。方法 采用空气消毒模拟现场试验和现场试验方法，对某空气消毒机的消毒效果及其安全性进行分析和讨论。结果 该空气消毒机组合等离子体、紫外线和光触媒等因子，启动消毒120 min，对试验舱内空气中白色葡萄球菌杀灭率为99.99%；对玻片上污染的大肠埃希菌、表皮葡萄球菌的灭活对数值均>4.00，对EV71肠道病毒、H1N1甲型流感病毒的杀灭率达100%。该空气消毒机作用120 min，对室内空气中自然菌的消亡率>90%。该空气消毒机在使用中无紫外线及臭氧泄漏。结论 该复合空气消毒机对多种微生物具有较好的消毒效果，无紫外线和臭氧泄漏。更多还原

【Abstract】 Objective To investigate the disinfection effect and safety of a new type of multi-effect composite air disinfection machine. Methods The disinfection effect and safety of the air sterilizer were analyzed and discussed by simulated field test and on-site test. Results The sterilizer combined plasma, ultraviolet light and photocatalyst and started disinfection for 120 min. The killing rate of the sterilizer on Staphylococcus albus in test chamber was 99.99%. The killing logarithm values were >4.00 against Escherichia coli and Staphylococcus epidermidis on contaminated glass slides.The killing rate for enterovirus EV71 and influenza A H1N1 were 100%, while the death rate of natural bacteria in the air exceeded 90%. Moreover, no leakages of ultraviolet and ozone were detected. Conclusion The sterilizer demonstrates significant effectiveness against a variety of microorganisms, without ultraviolet radiation and ozone leakage.更多还原
