某轨道交通地下车站环境卫生调查研究

A survey on sanitation of a rail transport underground station

目的调查轨道交通地下车站内环境的卫生状况和污染特征。方法通过春、夏、冬不同季节及早、中、晚不同时间段对某轨道交通地下车站内空气质量及集中空调通风系统进行检测,从而了解轨道交通内污染物的分布情况及影响相关指标的主要因素。结果地下车站内二氧化碳检测结果为0.031~0.218 mg/m^3、可吸入颗粒物检测范围为0.023%~0.158%、空气细菌数检测范围为5~7个/皿;在不同季节和不同时间段对轨道交通地下车站的环境质量有直接影响,地下车站集中空调通风系统的卫生指标在不同季节对轨道交通地下车站的环境质量有直接影响。结论地铁车站的环境质量存在着一些问题,今后的地铁卫生管理应加强新风供给,优化新风口的设置,并加强对集中空调通风系统的卫生管理来改善轨道交通地下车站的空气质量。

Objective To research the sanitation status and the pollution features in the underground station. Methods To find out the distribution of the pollutants in the rail transport underground station and the key elements influencing on the relevant indicators,the mehods of testing the air quality and the central AC ventilation system in different seasons,like spring,summer and winter and different period,like day,noon and evening were appled. Results CO2 was 0. 031-0. 218mg/m^3,PM10 was 0. 023%-0. 158% and total bacterial count was 5-7/glass which in underground stations would directly influence the environment quality in stations in different seasons and different periods. The sanitation indicators of the central air conditioning and ventilation system in underground stations would directly influence the environment quality in stations. Conclusion There are something problems in the environmental quality in the metro station,so hereafter the fresh air supply should be more enhanced the sanitation management,the setup of the fresh air inlets should be optimized,and the sanitation management of the central AC ventilation system should be enhanced in order to improve the air quality in the station.
