ADMS模型解析城区总悬浮颗粒物来源

The Analysis of TSP Sources in City with ADMS Model

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。

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 ADMS-air 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.
