目的分析某地铁线竣工验收时的室内空气和集中空调通风系统卫生质量,为行政管理和技术服务提供基础数据。方法选取某新建地铁线路一条,抽取其中8座结构相似地铁站,在竣工验收时对地铁站公共场所室内空气和集中空调通风系统进行监测。结果地铁公共场所室内空气检测指标均符合相关规定要求;集中空调通风系统首次监测,站点合格率为50.00%,不合格站点复检后合格率为75.00%。结论某新建地铁线路竣工验收时室内空气质量卫生状况尚可,但集中空调通风系统卫生状况堪忧。
Objective To analyze the hygienic quality of indoor air and central air-conditioning ventilation system at the completion of acceptance of a metro line, and provide the basic data for administration and technical services. Methods A new subway line was selected and eight similar subway stations were selected to monitor the indoor air and central air conditioning and ventilation systems of public places in the subway station at the time of completion and acceptance. Results The detection indexes of indoor air in subway public places all met the relevant requirements. For the first time monitoring of centralized air conditioning and ventilation system, the passing rate of the site was 50.00%, and the pass rate of unqualified stations was 75.00% after re-inspection. Conclusions Hygienic condition of indoor air quality is acceptable when a new metro line is completed and accepted, but the sanitation condition of central air conditioning and ventilation system is worrying.
