摘要
论述了AERMOD模式系统的基本原理、系统流程、参数确定、预处理过程,以及在火电厂大气环境影响预测中的应用步骤。以宁东热电项目为实例,采用AERMOD模式系统,选取符合项目特点的预测参数,预测该电厂大气污染物最大落地浓度,分析其预测成果对环境空气质量的影响。同时,提出了AERMOD模式系统在应用过程中存在的优缺点,以及解决对策。指出了利用该模式系统得出的预测值较为接近实际情况,适用于火电厂大气环境影响预测。
This paper presented basic principles of AERMOD modelling system, system processing, parameters se- lection, preprocessing,and application steps in the ambient environment impact assessment for thermal power plant emission. Author applied AERMOD modelling system in Ning Dong thermal power project, where prediction pa- rameters was selected in line with the characteristics of the project, to simulate the maximum ground concentration of atmospheric pollutants from the thermal power plant and evaluate the effects from the predicted results on ambi- ent air quality. Meanwhile, the advantages and disadvantages of the AERMOD model system in the application process have been examined, and the associated countermeasures were proposed as well. Finally the paper concluded that the predict results from modelling system proved to be approximate to real measurement in actual situation. AERMOD Model hence were proven to be suitable in atmospheric environment impact assessment for thermal power plant emission.
