【摘要】：利用CALPUFF模型,结合济南市大气环境监测数据和气象观测资料,模拟分析济南市东部老工业区重点工业源在7个重污染小时下对环境空气质量的影响。结果表明:东部老工业区重点工业源对济南市环境空气例行监测点位NO_2、SO_2和PM_(10)的占标率和贡献率均较小,不足3%,且随气象条件变化不明显。说明在重污染小时下,大气边界层高度较低,污染物不易达到近地面,其对近地面一次性大气污染物的影响较小。从污染物类别上看,重点工业高架点源对近地面NO_2和SO_2的影响较大,对近地面PM_(10)的浓度影响较小,说明近地面一次性大气污染物主要通过气态污染物传输。在重污染小时条件下,重点工业高架点源主要影响济南市建成区的中部和东部。
[Abstract]:Based on CALPUFF model, combined with atmospheric environment monitoring data and meteorological observation data in Jinan, the effects of key industrial sources in the eastern industrial zone of Jinan on ambient air quality under seven heavy pollution hours were simulated and analyzed. The results show that the proportion and contribution rate of the key industrial sources to the number of no _ 2O _ 2 and PM10 in the routine monitoring points of ambient air in Jinan are smaller, less than 3, and not obvious with the change of meteorological conditions. The results show that the height of atmospheric boundary layer is lower and the pollutant is not easy to reach the near surface under the condition of heavy pollution, and the influence on the one-time atmospheric pollutant near the surface is small. From the point of view of pollutant category, the point source of key industrial overhead has a great influence on NOS-2 and SO2 near the ground, and has little effect on the concentration of PM10 near the ground, indicating that the one-off atmospheric pollutants are mainly transported by gaseous pollutants. Under the condition of low heavy pollution, the point source of the key industrial overhead mainly affects the central and eastern parts of the built area in Jinan.
