本文以兰州市主城区内大型热电厂的外迁为例,在分析兰州市气象特征与大气环境质量现状的基础上,利用Aermod模式进行热电厂迁建前后对应的两个不同污染源对于兰州市主城区内NO2与PM10两种污染物浓度贡献的预测。
This paper sets the relocation of a large thermal power plant in Lanzhou as an example,on the basis of analyzing meteorological characteristics and present situation of the atmospheric environment quality,then,determine the parameters of pollution sources of the existing engineering and relocation project, using Aermodmodel to predict the concentration of pollutants from different pollution sources in our concerned place corresponding before and after the relocation.
