有效清洁自然通风与紫外线照射空气净化作用对比研究

目的寻求一种有效、安全、无毒、方便、实用、费用低、回归自然的空气净化方法。方法选择医院1、3、5、8层楼普通病房和治疗室的空气质量作为监测对象,在不同季节、不同时间,同时进行有效清洁后自然通风与紫外线照射前后的空气、物体表面采样,监测细菌菌落情况并进行相互对比分析。结果有效清洁后自然通风能使室内空气清新洁净,各项空气监测参数达到一般病房空气指标要求,与紫外线照射后空气监测结果进行比较,两者无显著性差异。结论有效清洁通风能取代或弥补目前医院紫外线照射存在的缺点及局限性,可作为病房内空气净化的常规方法。

A Comparative Study on Air Purifications by Effective Purity Ventilation and by Ultraviolet Irradiation

Objective To find an air purification method of high effects, safety, no poison, practical use, low cost and environmental protection. Methods The air quality in the wards and treatment room at the first, third, fifth and eighth floors was monitored after simultaneously using the methods of effective purity ventilation and ultraviolet irradiation in different seasons and at varied time. The samples were obtained from the air and the facial surface to understand and compare the colonies. Results By effective purity ventilation, the room air was make fresh and each factor for air monitoring met the regulated standards for general wards, with no significant difference when comparing with the method of ultraviolet irradiation. Conclusion Effective purity ventilation may take place of the generally adopted method of ultraviolet irradiation and can be used as a routine method of purifying the air in the wards.
