摘要 文章研究了世博会展馆内空气微生物污染的控制问题。研究表明,参观人数为400人/小时的情况下,展馆内微生物气溶胶产生量达到44000 cfu/h.m3。空调过滤系统若采用中效过滤,展馆内空气微生物浓度可至4406 cfu/m3,仍超过《室内空气质量标准》2500 cfu/m3的浓度限值,需使用消毒技术净化展馆内空气。增加中效过滤器能够有效去除可吸入颗粒物,有助于降低室内空气微生物浓度。 This paper studied treatment of air microorganism pollution in exhibition halls of the World Exposition. If the visitor current were 400 people per hour, the production rate of microorganism aerosol would be 44000 cfu/h · m^3. If medium effect air filters was adopted in centralized air conditioning system, the content of air microorganism would be 4406 cfu/m^3. It was still higher than the "Quality Standard of Room Air" (2500 cfu/m^3 ) , so air disinfection technology must be utilized. The research indicated that increase of medium effect air filter could reduce the content of microorganism in room air.
