Problems solved by technology
However, for groundwater, the experimental conditions of the indoor column are significantly different from the actual environmental conditions. On the one hand, the underground is in a dark and constant temperature environment; Therefore, the existing indoor column experimental research cannot truly reflect the conditions of the groundwater on site, which may have a significant impact on the experimental results, resulting in a discrepancy between the migration characteristics of elements and the degradation characteristics of pollutants and the actual situation. bit experiment to check

Description
Technical field [0001] The invention belongs to the technical field of groundwater pollution remediation, and more specifically relates to an in-situ column experimental simulation system and a simulation method used in groundwater wells. Background technique [0002] Elemental migration characteristics in groundwater and pollution treatment and remediation research often use column experiments for small-scale research. By injecting specific components of pollutants, it can simulate their migration and degradation characteristics in groundwater. By adding repair materials to the experimental column, inject Pollutants, you can study the removal effect and influencing factors of the repair materials on the pollutants. But for groundwater, the indoor column experimental conditions are obviously different from the actual environmental conditions. On the one hand, the underground is in a dark and constant temperature environment. On the other hand, the various water chemical component...
