| Abstract: | The permeability variation of the invasion interface of saltwater-freshwater was studied by the basic theory,application analysis and experiment simulation.We analyzed the division and salinity of brackish water in Hengshui region.According to the water sensitivity analysis,PHREEQC was applied to simulate the processes of mineral transport and transformation.The results indicated that high valence ion in brackish water exhibits better performance in the aspect of flocculation sedimentation for colloidal par... |
