Description

From a microperspective, this book investigates the interface interaction between organic pollutants and soil skeleton, as well as the electrochemical response and the interface mechanical mechanism of contaminated soil in thermal environments. Considering interface behaviors and mechanisms, a one-dimensional soil column and a large-scale three-dimensional laboratory model using steam injection technology were self-developed for the first time to discuss the removal pathways and effectiveness of pollutants under heat-moisture conditions in a simulated in-situ soil stress. In addition, this book also focuses on the mechanical performance and biological resilience of the thermally remediated soil to expand the reuse scenarios of these wastes. This study effectively integrates interdisciplinary knowledge such as soil mechanics, fluid flow in porous medium, and environmental chemistry and innovatively conducts systematic research using theoretical, experimental, and numerical simulation methods to fill the gap in current research on the interaction behaviors, fate mechanisms, remediation pathways, and reuse potential of organic contaminated soils. The methodology established in this book provides a good foundation for the characterization, efficient remediation, and reutilization of organic contaminated soils, filling the gap of a single discipline in solving the issue of contaminated sites and broadening the research perspective and depth for geo-environmental engineering.
