摘要(Abstract)：

利用AERMOD模型对某1 000 MW燃煤机组改造前后排放NO_X在大气中的传输、扩散过程进行了模拟,定量计算了NO_X环境浓度及其分布情况。研究发现:通过超低排放改造项目削减NO_X排放,可使环境空气中NO_X最大落地浓度大量减少、占标率明显下降;各峰值分布区域污染物浓度降幅显著,各时段均值占标率大幅下降;全区域各时间段浓度值均降低、分布梯度变小。研究结果表明:火电行业通过"超低排放"进一步控制NO_X污染对环境影响正效益显著,发电厂周边环境空气质量得以整体大幅提升。
The diffusion and transmission in the atmosphere of NO_X emissions from a 1 000 MW coal-fired power plant is simulated by using AERMOD modeling system to calculate the ambient concentration and distribution of NO_X. The results show that the reduction of NO_Xby "ultra-low emission" transformation enables greatly reduction of maximum ground concentration in ambient air and decrease of the ratio to standard concentration; the pollutant concentration in peak distribution area decreases and the mean values to standard concentration at each time period are lowered greatly; the concentration value in the whole region at every time period decreases and the distribution gradient of NO_Xbecomes smaller. The research shows that further control of thermal power industry over NO_Xpollution by "ultra-low emission" has positive benefit on the environment, and the ambient air quality around the power plant is notably improved.
