某铁路地区客运站候车室空气质量和微小气候调查分析

Investigation and Analysis of Air Quality and Microclimate in the Waiting Room of Passenger Stations in a Railway Area

为了解某铁路地区客运站候车室空气质量状况,对13个客运站候车室内的空气质量和微小气候状况进行采样监测。结果表明,各客运站相对湿度、风速、一氧化碳、二氧化碳、可吸入颗粒物、噪声、照度、空气中细菌总数等监测项目指标均符合《公共交通等候室卫生标准》(GB 9672—1996)、《公共场所卫生指标及限值要求》(GB 37488—2019)标准;高速铁路和普速铁路客运站候车室均存在温度不达标情况,两者不达标率差异有统计学意义(χ^(2)=2.57,P<0.05)。建议该地区客运站应严格把控候车室内开窗通风时长、及时维修候车室供暖设施设备、适当增加供暖空调数量、及时调整空调供暖温度等,为候车旅客提供舒适、卫生、安全的候车环境。

To understand the air quality in the waiting rooms of passenger stations in a railway area,the air quality and microclimate in the waiting rooms of 13 passenger stations were sampled and monitored.The results show that the monitoring indexes of relative humidity,wind speed,carbon monoxide,carbon dioxide,inhalable particulate,noise illumination,total bacterial count in the air,etc.at each passenger station all meet the standards of GB 9672—1996 and Hygienic indicators and limits for public places (GB 37488—2019).The temperature in the waiting rooms of passenger stations of high-speed railway and general-speed railway is not up to standard,and the difference between them is statistically significant (χ^(2)=2.57,P<0.05).It is suggested that the passenger stations in this area should strictly control the ventilation time of opening windows in the waiting room,timely repair the heating facilities and equipment in the waiting room,appropriately increase the number of heating air conditioners,timely adjust the heating temperature of air conditioners etc.,so as to provide a comfortable,hygienic and safe waiting environment for waiting passengers.
