ADMS模型解析城区总悬浮颗粒物来源

以污染源排放数据为基础,应用ADMS-城市扩散模型模拟分析了鞍山市尘各污染源对空气环境质量的贡献。结果表明,来自污染源的浓度贡献值占总量的52%;二次尘及外来尘浓度贡献占48%;矿山开采二次尘的浓度贡献占16%;鞍钢炼铁厂的浓度贡献占19.6%;鞍钢化工总厂浓度贡献占5.6%;供暖锅炉浓度贡献占9.3%。低、中、高架源浓度贡献百分比分别为68.1%、29.0%、2.9%。低架源吨排放量浓度贡献为高架源的2.4倍。

The Analysis of TSP Sources in City with ADMS Model

On the basis of the air pollution emission data,the contribution of each dust pollution source to the air environment quality in Anshan is analysed with ADMSair diffusion models.The result shows that the contribution from pollution sources occupies 52%.The contribution FROM secondary dust and outside source dust occupies 48%.The mine exploitation contributes 16% to the concentration as a secondary dust source.The emission from angang Iron Mill contributes 19.6% among the local pollution sources,while the emission from.Angang Chemical Engineering contributes 5.6% and the emission from heating boilers contribute 9.3%.Among the pollution sources from chimney stacks,the low,mid and high ones contribute 68.1%,29.0%,2.9% to the concentration,respectively.The contribution(emission amount by ton) from low chimney stacks was 2.4 times as that of high ones.
