基于Feflow的地下水污染数值模拟及预测——以宁波某印染厂为例

Numerical Simulation and Prediction of Groundwater Pollution Based on Feflow——An Illustrative Study of a Printing and Dyeing Factory in Ningbo

近年来随着社会经济快速发展,宁波地区地下水生态环境受污染的风险程度显著提高.以宁波某印染厂为例,为了分析其工业污水对当地地下水环境的潜在威胁,利用Feflow软件对研究区地下水渗流及溶质运移进行数值模拟.模拟结果表明:基于较为理想的地下水渗流模型,在一定假设条件下溶质运移模型可以较好地模拟污染物在地下水中的运移规律.印染厂污水泄漏后将对研究区造成长达10年的不利影响,20年后污染物浓度才逐渐消散.

In recent years, with the rapid development of social economy, there has been a marked rise in the risk of pollution of groundwater ecological environment in Ningbo. In order to analyze the potential threat of industrial wastewater to local groundwater environment, the groundwater seepage model and solute transport model in the study area were conducted by Feflow. The simulation results show that the solute transport model can simulate the transport of pollutants in groundwater based on the ideal groundwater seepage model. The leakage of the pollutants from the printing and dyeing factory will affect the study area in the next 10 years until the pollutants gradually dissipate in 20 years.
