摘 要: 提出一种适用于河流突发性水污染应急处理的扩散模型。结合实例,采用平面离散点的三角剖分与二维水质扩散模型,实时计算每个河流网格中心污染物浓度。模拟了突发性水污染事故中污染物的时空分布,定量模拟了河流监测断面污染物到达的时间和浓度值。 For accidental water pollution, this paper proposed a suitable river pollution emergency treatment of sudden diffusion model. Combined with river examples, using discrete points,planar triangulation and 2D water quality diffusion model, the paper calculated each pollutant concentrations river network cell centers in real-time. And then, the paper simulated the spatial-temporal distribution of pollutants in sudden water pollution accidents, and discussed pollution monitoring sections arrival time and concentration values quantitatively.
