【摘要】 本文主要研究了济南市大气颗粒物来源解析中样品的采集及处理技术。通过对济南市大气颗粒物污染源的深入调查,确定排放源类的类别为土壤风沙尘、工业燃煤(油)飞灰、民用燃煤(油)飞灰、机动车尾气燃油飞灰、建筑水泥尘、钢铁尘、扬尘排放源类。根据各种排放源类的不同,须采取不同的采样方式和处理技术,确保样品的代表性和样品分析的最佳效果,同时对颗粒物污染源排放的季节性和季节稳定性作了特征分析。通过受体样品和源样品的粒度分散度测量及数据处理的结果得出尘粒在空气中的沉降和扩散情况,为空气中粗、细颗粒物的组成提供科学依据。为颗粒物来源解析的研究奠定了成功的基础。更多还原

【Abstract】 This paper researched on the sample collection and processing technology of the atmosphere granules.Through survey for Jinan’s atmosphere granule,it confirmed that granule sources come from soil and sand dust blown by wind,industry coal(fuel) flying ash,civilian coal(fuel) flying ash,motor vehicle tail gas fuel flying ash,architecture cement dust,steel dust,dust blown by wind.Different sampling mode and processing technology should be taken according to different sources and the representative of sample and the samples analysis optimum effect should be insured.At the same time,this paper analyzed season nature and stability of atmosphere granule sources.By means of surveying sample dispersion and data processing result,it is able to get the settlement and diffuse situation of sample granules.This offers scientific gist for composite of chick or thin granule in the open air and build a successful foundation for origin research of the atmosphere granules.更多还原
