摘　　要：以上海市金山区某拟建项目为例,为分析区域环境对其产生的影响,采用Ansys结合物呈线条状扩散,有效影响范围可达到10km以外。同时,基于空气质量指数(AQ)对污染物来源、污染物性质等在不同风向和风速下进行最不利气象条件仿真模拟,得出结论并提出应对措施。成果可为拟建项目的环境影响评价提供参考,也可为沿岸化工厂排放口设置及功I能优化提供一定的理论指导。Taking a proposed project in Jinshan District,Shanghai as an example,Ansys Fluent is used to establish a 3D non-stationary pollution source model,combined with a BIM 3D digital sand table to load simulation data,and carry out dynamic simulation of the environmental impacts of pollutant emissions from the project's peripheral sources.At the same time,based on the air quality index(AQI),the most unfavourable meteorological conditions are simulated for pollutant sources and pollutant properties under different wind directions and wind speeds,and conclusions are drawn and countermeasures are proposed.The results can provide reference for the environmental impact assessment of the proposed project,and also provide some theoretical guidance for the optimisation of the setting and function of the discharge outlets of the coastal chemical plant.
