【摘要】 以上海市某冶金企业为例,该厂有正常运行的冶炼炉13座,每年向大气中排放大量颗粒污染物。基于高斯倾斜烟羽模式,整理了2003年上海市全年的气象资料,运用气象概率矩阵法计算了该厂直排点源及无组织面源排放颗粒物的影响,得出了厂区内无组织排放颗粒物落地浓度等值线图。计算结果表明,厂区内颗粒物污染主要来自无组织面源,污染集中在厂区中心的污染源附近;直排点源对环境的影响较小,污染主要集中在下风向。更多还原

【Abstract】 The dust emission of a metallurgic plant in Shanghai, as an example with 13 sets of smelting furnace and large amounts of discharged pollutant, was studied in this paper. Based on the Gauss Sloping Fume Model, the meteorological data in 2003 were analyzed through the Meteorological Probability Matrix Method, the diffusions of fugitive dust from point sources and area sources were calculated and described in the isograms of the particulate concentrations. The calculation results showed that the particulate pollution was mainly from the fugitive area sources and being concentrated in the center of this plant near the pollution sources; and the fugitive pointsources had very little impact on the environment , mainly concentrated in the downwind of the pollution sources.更多还原
