人防工事内空气的净化和消毒

Air Purification and Disinfection in Air Defence Fortifications

在通风条件很差或人群密度较高的人防工事内,空气中的细菌多,需进行净化或消毒以改善空气质量.用空气循环净化的方法,可有效地减少空气中的细菌和霉菌,降低CO_2浓度,消除臭气,可使手术室内空气的清洁度从Ⅲ级提高到Ⅱ级水平。ZSH/W型高效紫外线灯对空气消毒的效果比普通紫外线灯好,而且产生的臭氧少。其空气消毒的杀菌率达到71.7％～82.7％。用88型消毒剂对病房、手术室、X线透视室、办公室等空气消毒,杀细菌效率达到99％,杀霉菌效率达86％。本消毒剂无腐蚀性,毒性低,使用安全。

The research work on air purification and disinfection in air defence fortifications was carried out. The air purification method could reduce bacteria, fungi, CO2 concentration and odor in the air. It might increase the clean degree of the air from Degree HI to Degree Ⅱ in the operation room. Efficiency of ZSH/W type ultraviolet lamp for air disinfection was better than that of other ultraviolet lamp. The ozone produced was also less. Its bactericidal rate was 71.7%-82.7%. When Type 88 disinfectant was used for air disinfection in wards. operation room, X-ray room and office, its bactericidal rate was 99%, and fungicidal rate was 86%. All of these methods were very effective for indoor air purification and idsinfection.
