摘要
目的研究以过滤、紫外线和光催化等因子组合的空气消毒器消毒相关性能。方法采用空气微生物采样器采样和检测方法进行了实验室试验和现场消毒试验。结果在20 m3气雾室内开机运行60 m in,对人工污染在空气中的白色葡萄球菌的杀灭率各次均达到99.94%以上。在48 m3的房间现场试验条件下,开机运行60 m in对室内空气中自然菌的消除率均达到95.49%以上;在有3人活动的20 m3气雾室内,开机运行60 m in后对空气中细菌的杀灭率均达到95.55%以上。结论该多因子组合空气消毒器在实验室和现场消毒试验条件下都具有良好的除菌效果,并具有人在条件下持续性消毒功能。
Objective To study the related properties of air disinfector operating on multifactor combination including filtration, ultraviolet rays and photocatalysis. Methods Sampling with air microbial sampler and examination method were used to carry out laboratory test and on - the - spot disinfection trial. Results Operation of the disinfector for 60 min in a 20 m^3 aerosol chamber killed over 99.94% of Staphylococcus albus artificially contaminating the air each time. Under condition of on - the - spot trial in a 48 m^3 room, operation of the disinfector for 60 min eliminated over 95.49% of the natural bacteria in indoor air. In a 20 m^3 aerosol chamber with 3 persons moving about in it, operation of the disinfector for 60 min killed over 95.55% of the bacteria in air. Conclusion The multifactor combination air disinfector has good bacteria - eliminating efficacy in both laboratory and on - the - spot disinfection trial conditions and also has continuous disinfection function in occupied places.
