通风空调环境中微生物气溶胶污染及其防治

Microbial Aerosol Pollution in Ventilation and Air Conditioning Systems:Prevention and Control

针对国内外通风空调环境中微生物气溶胶污染,介绍了通风空调环境中微生物的来源、传播途径、危害特性、生物特性、微生物气溶胶的受力特性、生物颗粒悬浮模型。并提出一种健康空调系统的构建,主要包括:通风空调系统形式选择、微生物监测和检测、微生物控制与消除、应急处理和事后评价。最后提出了未来需要进一步研究的问题,为健康室内环境的构建和提高建筑内部环境安全性提供参考依据。

Aiming at control of the environmental pollution of air microbe aerosol in ventilation and air conditioning systems, this paper overviewed the literatures in regard to the sources of microorganisms, propagation pathway, hazard characteristics, biological characteristics and mechanical properties of microbial aerosols, as well as the biological particle suspension model; in addition, a structure of an immune air conditioning was suggested, which involved selection of ventilation and air conditioning systems, the testing of microbiological monitoring, microbial control and elimination, emergency handling and the afterwards evaluation; and finally, the problems that need further investigation were pointed out for the safety of building interior environment.
