春运旅客列车车厢环境空气质量调查分析

目的了解春运期间不同类别旅客列车车厢环境空气质量差异。方法抽样调查车厢内的温度、相对湿度、风速、二氧化碳、一氧化碳、细菌总数指标,按列车状态、座别、超员情况对其结果进行统计分析。结果细菌总数、二氧化碳指标多数超出标准,温度指标多数低于标准,相对湿度、风速指标大多数符合标准,一氧化碳指标全部符合标准。结论春运旅客列车车厢环境空气质量较差,应采取综合干预措施予以改善。

Investigation on the Ambient Air Quality in the Passenger Train Compartment during the Spring Festival Transportation

Objective To study the main distinctions of the ambient air quality in the different kinds compartments of the passenger train during the Spring Festival Transportation. Methods Analyse the temperature, relative humidity, wind speed, carbon dioxide, carbon monoxide and index of the aerobic bacterial count(the total number of bacterium) by the spot check, according to the state of the train, grades of the seat, degrees of the overload.Results Indexes of the aerobic bacterial count and carbon dioxide are mostly higher than the current standard, the temperature lower than the standard on majority. Over the part of the indexes of the relative humidity and wind speed are up to the standards. The index of the carbon monoxide is accord with the demands entirely. Conclusion During the period of the Spring Festival Transportation,the quality of the environmental air of the passenger train compartment is bad, it should be controlled by comprehensive intervene measures.
