濱海地下水交互帶中的膠體運(yùn)移行為研究綜述
[Abstract]:Based on the analysis of the existing researches at home and abroad, the law of colloidal migration in the process of coastal groundwater interaction is summarized, with emphasis on the macro-migration and microscopic mechanism of colloids under the displacement of salt and fresh water. Colloid can become the material transport link between sea and land in the interaction of coastal groundwater. The migration behavior of colloid is mainly affected by the fluctuation of hydrochemical parameters of groundwater and controlled by the type and quantity of colloid. The surface potential, groundwater pH, ionic strength and other factors have the characteristics of hydrodynamic, multi-factor interaction in water environment, and the uncertainty of spatial blockage and agglomeration structure change in the aquifer. In the future study on colloid behavior in coastal groundwater interaction zone, we should pay attention to basic investigation, consider colloid colony effect, and consider the sensitivity of coastal aquifer to hydrodynamic and hydrochemical conditions. The uncertainty of colloid migration in multiphase system and its synergistic transport to pollutants were studied in order to construct a unified analysis system and prediction mechanism for coastal resource study.
