Abstract

The invention discloses an experimental device for researching the migration law of pollutants under the interaction of a river and underground water, and relates to the technical field of research onthe migration law of pollutants. The experimental device comprises a simulation water tank used for simulating filling of an aquifer and an aeration zone; a movable water tank used for controlling aleft water head of the simulation water tank; a fixed water tank used for controlling a right water head of the simulation water tank; and a simulated riverbed arranged in the upper groove of the simulated water tank. The experimental device has the beneficial effects that the quartz sand with proper particle size after acid washing and alkali washing is used for simulating the water-containing layer, and the water head difference between the fixed water tank and the movable water tank on the two sides is adjusted by simulating the arrangement of a riverbed so as to simulate the precipitation,so that the underground water flow field is changed; different supply relations between underground water and surface water are changed by changing the water level of the simulation water tank through the water pump, so that an underground water flow field is influenced. The experimental device is reasonable in design and simple to operate, and has the characteristics of high repeatability and operability.

Description

technical field [0001] The invention relates to the technical field of pollutant migration law, in particular to an experimental device for studying the movement law of pollutants under the interaction between rivers and groundwater. Background technique [0002] Groundwater and surface water are always inseparable as a whole. Surface water (such as rivers, etc.) enters groundwater through infiltration, leakage, etc., and groundwater enters surface water by recharging rivers during drought periods. Therefore, as the seasons change, the surface water interacts with the groundwater and significantly affects the groundwater flow field. Pollutants may enter the surface water and pollute the groundwater along with the groundwater flow field, or the pollutants may enter the surface water directly from the groundwater through the recharge of the river. The movement of the pollutants is obviously affected by the interaction between the river and the groundwater. [0003] At present...
