摘要
为应对区域大气复合污染的严峻态势,亟需建立健全空气污染来源追因系统。三维空气质量模型可以克服外场观测与烟雾箱模拟高成本与低时效的缺点。主要介绍了使用空气质量模型解决大气污染物来源分析的方法,其中:过程分析(PA)可用于估算各物理过程与净化学过程对污染物浓度的影响;臭氧来源解析技术(OSAT)和颗粒物来源解析技术(PSAT)通过标记不同地区各类排放源一次污染物的排放,得出不同受体点位主要一次与二次污染物的来源或主要排放源区对区域各项污染物浓度的贡献。
To cope with the severe situation of the regional air pollution, it is urgent to establish a sound source apportionment system of air pollution. 3 -D air quality model could overcome the shortcomings of high cost and inefficiency in field observation or smog chamber. Methods of using air quality model to solve the problem of air pollutants source apportionment were mainly introduced, in order to provide reference about establishing an environment management system in line with the international advanced level. Process analysis (PA) could be used to estimate the influence of the physical and chemical processes on the pollutants concentration. Through marking emissions of pollutants of different types and in different areas, ozone source apportionment technology (OSAT) and particulate source apportionment technology ( PS AT) could figure out the sources of mainly primary and secondary pollutants in different receptors or the regional contribution of various pollutants by main emission areas.
