目的比较托幼机构不同空气净化消毒方法的实际使用效果,供托幼机构选择空气净化方法参考。方法通过生物和理化测定方法,对托幼机构使用的不同空气净化方法的净化消毒效果进行测定和比较。结果在测定的循环风紫外线空气消毒机、紫外线灯、艾条熏蒸法、食醋熏蒸法和自然通风法等五种空气净化方法中,对空气中细菌清除率基本一致,但以循环风紫外线空气消毒机对空气中尘埃颗粒净化效果最好。结论在比较的五种空气消毒和净化方法中,以循环风紫外线消毒机净化空气的效果最好。
Objective To compare the practical effects of different air purification and disinfection methods in nurseries and kindergartens, and to provide a reference for air-cleaning methods for nurseries and nurses. Methods By biological and physical and chemical measurement methods, nurseries and nurses institutions to use different methods of air purification purification and disinfection were measured and compared. Results In the air purifying method of circulating air UV air disinfection machine, UV lamp, moxa fumigation method, vinegar fumigation method and natural ventilation method, the bacterial clearance rate in the air was basically the same, but the circulating air UV air Disinfection machine dust particles in the air purification best. Conclusion Among the five comparison methods of air disinfection and decontamination, it is best to use the circulating UV disinfection machine to purify the air.
