不同消毒方法对室内空气消毒效果观察

Effectiveness of Different Indoor Air Disinfection Methods

目的寻找室内空气快速、简便、高效的消毒方法。方法比较A法(水擦+紫外线)、B法(含氯消毒剂擦+紫外线)、C法(含氯消毒剂擦+含氯消毒剂喷雾)对无菌间空气的消毒效果。结果A、B、C3种方法均可使无菌间空气中自然菌下降达到合格要求,但C方法比A、B方法的消毒效果好(P<0.05)。结论C方法对室内空气进行消毒简便易行,效果最佳。

Objective To explore a simple, effective and rapid method for indoor air disinfection. Methods Three kinds of disinfection methods were carried out (method A: wiping surfaces of floor and walls of room with water and ultraviolet irradiation, method B: wiping surfaces of floor and walls with chloro-disinfectant and ultraviolet irradiation, method C: wiping surfaces with chloro-disinfectant and spraying chloro disinfectant containing chlorine) and the effectiveness of different disinfection methods was compared. Results The result showed that all of the three methods could decrease natural fallen bacteria count in isolated room air to up to the standard, and the disinfection effectiveness of method C was better than the method A and method B. Conclusion The result indicated that method C was an effective and simple method for indoor air disinfection.
