采用AERMOD大气预测软件模拟预测GGH对火电厂大气污染物排放的影响,同时对电厂周围大气污染物进行现场监测,预测和实测结果表明SO2／、NO2浓度均满足环境空气质量标准中的二级标准要求,若不考虑叠加背景值的影响,SO2占标率远小于NO2占标率。若采用AERMOD估算模式模拟预测,其预测结果高于AERMOD大气预测软件模拟预测结果,同样SO2占标率远小于NO2占标率,且NO2部分预测结果超过二级标准,因此推荐电厂安装脱硝设施。根据模拟结果可知,加装GGH对烟气抬升高度影响显著,有利于增加污染物的扩散距离,但对污染物的排放浓度值未有显著影响。

Using AERMOD software to study GGH’S contribution to power plant’s pollutants emission concentration,simultaneously in-situ monitoring ground concentration of pollutants emission,both results shows that both the concentration of SO2 and NO2 reaches Ⅱ grade of ＂ Ambient air quality standard＂.Without considering background concentration of pollutants,the SO2’s ratio to standard is greater than NO2’s.However,using AERSCREEN to predict pollutants emission concentration,its results is greater than that by AERMOD soft,parts of NO2’s results exceed Ⅱ grade standard of ＂ Ambient air quality standard＂,so it is wise to install denigrator in power plant.The results also shows that GGH can significantly raise plume rise and make its diffusion distance more farer.However,GGH almost has no effect on concentration of pollutants emission.
