【摘要】：目的了解华北某坑道内进驻人员前后的空气质量变化情况。方法选择坑道内1个房间,观察6名人员进驻后微小气候(温度、相对湿度、气压、风速)、常见无机有害气体(CO、CO2、O3、H2S、SO2、NO2、NH3)、氧气、总悬浮颗粒物(TSP)浓度和细菌总数,并与进驻前及坑道外检测结果比较。结果气温、相对湿度、气压、风速的测定值和CO、CO2、O3、H2S、SO2、NO2、NH3浓度及细菌总数,人员进驻前坑道内和坑道口外比较无明显差异,符合《屯兵坑道环境卫生学要求》和《人防工程平时使用环境卫生标准》要求;人员进驻后,坑道内TSP浓度为0.55 mg.m-3,明显高于进驻前的0.11 mg.m-3,超过标准要求;其他各项指标检测结果与进驻前比较变化不明显,均符合标准要求。人员进驻后,7:00、14:00、19:00坑道内的气温、相对湿度、气压、O2浓度、细菌总数、TSP浓度变化不显著(P0.05),H2S、SO2、NO2、NH3浓度未检出或接近0。结论人员在坑道内工作、学习和生活时,影响坑道空气质量的主要因素是TSP。
[Abstract]:Objective to investigate the changes of air quality before and after entering a tunnel in North China. Methods A room in the tunnel was selected to observe the microclimate (temperature, relative humidity, air pressure) of 6 people. Wind speed, common inorganic harmful gases, COCO2CO2O3H2SSO2NO2NO2NH3, oxygen, total suspended particulates (TSPs), and total bacterial count were compared with those before and outside the tunnel. Results temperature, relative humidity, air pressure, wind speed, COCO2O3H2SSO2NO2NO2NH3 concentration and the total number of bacteria were measured. There is no significant difference between the personnel in the tunnel before entering the tunnel and outside the tunnel entrance, which conforms to the requirements of Environmental Sanitation requirements for military tunnels and the Environmental Sanitation Standards for Civil Air Defense projects at ordinary times. The TSP concentration in the tunnel was 0.55 mg 路m-3, which was significantly higher than 0.11 mg 路m-3 before entering, which exceeded the standard requirement. The results of other indicators were not obviously different from those before entering, and all of them met the standard requirements. The air temperature and relative humidity in the tunnel after the entry of the personnel were 7: 00 to 14: 1: 00: 00: 00. There was no significant change in the concentration of tsp at atmospheric pressure and total bacterial count. Conclusion the main factor affecting air quality in the tunnel is TSPs when the concentration of NH3 is not detected or close to 0. Conclusion the air quality of the tunnel is mainly affected by TSPs when the workers work, study and live in the tunnel.
