Abstract

The invention discloses a simulation experiment method of groundwater replenishment, which is realized by relying on a simulation experiment platform of groundwater replenishment. The experiment platform includes a dynamic water level simulation device, a vadose zone simulation device, a rainfall irrigation simulation device and a groundwater replenishment simulation device. By adding different pollution sources in the vadose zone simulation device, the evolution of groundwater flow field during the recharge process is simulated, and various factors affecting the quality of potentially polluted groundwater during the groundwater recharge process are simulated in the pollution correlation simulation device to obtain a variety of key parameters.

Description

technical field [0001] The invention relates to the technical field of groundwater quality safety and replenishment, in particular to a simulation experiment method for groundwater replenishment. Background technique [0002] In hydrogeology, the vadose zone refers to the geological space between the water table and the surface. It plays an important role in the formation and change of groundwater resources. It not only has the ability to store water, but also has the function of transmitting surface infiltration water. The vadose zone is an important barrier to prevent groundwater pollution, but there are also a large number of potential pollution sources, mainly including: ①Surface sewage infiltrates through the vadose zone to pollute groundwater. It is a very common phenomenon; ②Contaminated vadose zone soils lead to groundwater pollution under the infiltration of atmospheric precipitation or irrigation water. The reasons can all lead to the pollution of the soil in the...
