Abstract:The spatial distribution of organic contamination in soil-groundwater system is controlled by thermal, hydrodynamic, chemical and microbial fields. Understanding the migration and distribution patterns and influence mechanism of organic contaminants in soil-groundwater system is a prerequisite for effective remediation. Temperature is an important factor affecting the migration and spatial distribution of organic contaminants in soil and groundwater by changing their physicochemical properties and key parameters controlling multiphase flow and chemical/microbial perturbation. In this paper, the relationships between the physicochemical properties (density, viscosity, solubility) of organic contaminants and the key parameters of microbial/chemical actions (volatilization, adsorption and biodegradation) and temperature are analyzed, and the studies of simulation on organic contaminants in soil-groundwater driven by thermal coupling are reviewed. Finally, the mathematical model coupling non-isothermal multiphase flow, solute transport and physiochemical driving processes is proposed to quantitatively simulate the migration and transformation patterns of organic contaminants under temperature-driven conditions. It can provide references for quantitatively exploring the migration and transport patterns of organic contaminants driven by thermal field coupling.
