Abstract

Abstract

Numerical simulation technology is widely used in the remediation of polluted groundwater and usually used in the design stage of remediation technology. However, the accuracy of the model parameters obtained is limited to a certain extent in time and space, so there are many uncertainties in the remediation effect. It is more practical to apply numerical simulation technology to the actual repair process. In combination with the example of groundwater pollution remediation, a three-dimensional numerical model was established to simulate groundwater flow and solute transport, considering the characteristics of land mass such as convection, dispersion, and adsorption. Parameter correcting was performed with monitoring data of water level and quality of several monitoring wells during groundwater restoration. The changing trend of pollutants in groundwater with the development of the groundwater remediation process was analyzed, and the extraction and treatment scheme was adjusted in time, in order to guide the implementation of subsequent groundwater remediation. The results indicated the method of numerical model modification based on the monitoring data, during the restoration process, can truly reflect the characteristics of the groundwater system in the simulation area, and effectively guide the follow-up restoration implementation.
