摘要
目的为了解地铁车站公共场所集中空调通风系统卫生状况,为地铁运营卫生管理提供依据和建议,为卫生行政审批提供科学依据。方法 2011年至2012年对广州市三条线路的地铁车站公共场所集中空调通风系统进行了调查与检测。结果三条线风管内表面积尘量和积尘微生物、新风量和嗜肺军团菌合格率均为100%;三条线车站公共场所集中空调通风系统送风指标细菌总数指标合格率A线为82.7%(110/133),B线为98.4%(62/63),C线为85.7%(54/63);真菌总数指标合格率A线为90.2%(120/133),B线为85.7%(54/63),C线为44.4%(28/63);PM10 A线为34.6%(46/133),B线为54.0%(34/63),C线为76.2%(48/63)。结论地铁车站公共场所集中空调通风系统送风空气质量存在一定卫生问题,应在今后的管理与维护中加以重视。
Objective In order to know about the hygiene of the air conditioning system in the public spaces of the subway station we conducted this monitor to provide the basis for Management and administration. Methods From 2011 to 2012 we monitored centralized air ventilation system in three lines of Guangzhou Metro Station. Results Weight and microbe of the dust in the inner surface of the duct, fresh air and cooling water, condensate of 3 lines are all qualified. The results of Microbe and PM10 of the air supply are as follows, the number of bacteria qualified rate were： line A 82.7% （110/133） , line B 98.4% （62/ 63）, line C 85.7% （54/63） ; the fungi qualified rate were： line A 90.2% （120/133）, line B 85.7% （54/ 63） and lines C was 44.4% （28/63）; the PM10 qualified rate were line A 34.6% （46/133）, line B 54.0% （34/63） ,line C 76.2% （48/63）. Conclusion The centralized air ventilation system of subway station has some hygiene problem, we should pay more attention on it in the future management and maintenance.
