摘要: 地下水重金属污染运移规律对污染治理十分重要，重金属污染数值模拟是了解地下水重金属污染运移过程的重要手段，污染物运移模拟结果贴合实际变化规律很大程度上依赖于地下水重金属动力学运移模型、参数和算法的设置，国内尚缺乏可根据场地污染情况自定义数学模型与算法的地下水模拟软件。本文以铬污染为例，基于现有的勘察工程数据和实验得到的污染场地模型参数，构建铬污染运移三维动力学数学模型，自编模块实现有限差分离散化方法构建并求解三维数值模型，模拟六价铬在污染场地中的三维运移过程，为分析铬污染物运移规律提供技术支撑。
Abstract: The transport law of heavy metal pollution in groundwater is very important for pollution control. Numerical simulation of heavy metal pollution is an important means to understand the transport process of heavy metal pollution in groundwater. The simulation results of pollutant transport are consistent with the actual change law, which largely depends on the setting of dynamic transport model, parameters and algorithm of heavy metals in groundwater. There is still a lack of groundwater simulation software which can customize the mathematical model and algorithm according to the site pollution in China. We take chromium pollution as an example, construct a three-di- mensional kinetic mathematical model of chromium pollution transport based on the existing survey engineering data and experimental model parameters of the contaminated site, and construct and solve a three-dimensional numerical model based on a self-programmed module to implement a finite difference discretization method to simulate the three-dimensional transport process of hexavalent chromium in the contaminated site, providing technical support for the analysis of chromium pollutant transport law.
