摘　　要：随着焦化行业的快速发展,其环境污染问题也日益暴露出来,以大气污染最为严重。不同的焦化项目运行之后将会排放不同量的苯、CO、NH3、H2S、SO2和苯并芘等有毒有害气体,其排放量大小对项目所在地周围环境有着巨大影响,因此准确预测一个焦化项目对周围大气环境影响的程度,对决定此项目是否可行有着重大意义。以甘肃省某100万t焦化项目为例,在确定污染源的前提下,利用AERMOD模型,从气象数据及地形数据的获取方式、污染源选项、污染源设置、背景图、评价范围、网格点关心点的选取等方面详细介绍了利用AERMOD预测焦化行业大气环境影响的重点及技术要点,最后以SO2预测结果为例,分析了污染物对周围环境的影响程度,并简要介绍了影响污染物浓度分布的各个因素。希望为焦化行业大气环境影响预测以及AERMOD模型使用提供一定参考。With the rapid development of the coking industry,the problems of environmental pollution are also increasingly exposed,air pollution is the most serious.Different coking project will emitting different amount of benzene,CO,NH 3,H 2 S,SO 2 and benzo（a） pyrene etc and other toxic or harmful gases,the quantity of the emission has a huge impact on the surrounding environment of the project site.Therefore,to accurately predict the extent of the impact of a coking project on the surrounding atmospheric environment,is of great significance in determining whether is this projectis feasible.Taking a certain one million tons of coking project in Gansu Province for example,on the premise of identifying sources of pollution,using AERMOD model,from the way to get meteorological data and terrain data,options and pollution sources,pollution sources arrangement,the background image,the evaluation scope,the grid points and the concerned points etc,it was introduced in detail the focus and technical points of using AERMOD to predict atmospheric environmental impact of the coking industry.Finally SO 2 predicted results were used to analyse the impact of pollutants on the surrounding environment,and briefly described the various factors that affect the distribution of pollutant concentration,which provided some references for forecasting the coking industry atmospheric environmental impact,as well as using the AERMOD model in the future.
