基于数值模拟的傍河水源地潜在污染水力调控优化技术

傍河饮用水源地污染控制技术是我国环境保护与饮水安全领域的研究热点。选取松花江流域佳木斯七水源大型水源地为研究区,综合分析其水文地质条件,应用数值模拟方法拟合研究区水动力学场及水化学场。在此基础上运用MGO模块的模型基础,采用全局寻优算法——遗传算法,分析不同抽水量及井位对七水源-废醪池污染羽进行水力调控的效果,得出最优井位及抽水量。同时通过分析清除污染源和未清除污染源情况下,不同观测井中污染物浓度的变化趋势,探讨了水力调控优化控制技术对傍河水源地污染控制的有效性,为傍河水源地的安全供水提供技术保障。

Optimal control technology of hydraulic regulation in water resource area along rivers based on numerical simulation

Pollution control technology of water resource area along rivers is a research hot topic in the field of environment protection and drinking water security in China. In accordance with historical data and hydrogeological conditions in the study area, the numerical simulation method and MGO module model were applied to the study area based on the regional groundwater flow field and initial concentration of groundwater pollution. By means of global optimization algorithm-genetic algorithm, the best exploitation quantity and location of pumping wells were optimized to control the contaminant plume in the research area. In the two basic conditions of eliminating pollution sources and controlling pollution sources, the variation trend of pollutants in different observation wells was analyzed and the effectiveness of the hydraulic control technology was explored in order to provide technical support for ensuring water safety in water resource area along rivers.
