Problems solved by technology

Among them, the tightly coupled model is not suitable for the practical application of groundwater environment simulation in general, especially for regional or watershed scale problems, due to the disadvantages of huge mesh size, high calculation cost, and many parameters required; while the one-way coupled model Only considering the unilateral effect of the vadose zone on the aquifer, there are problems such as unreliable simulation results

Abstract

The invention discloses an underground water environment simulation method and device based on aeration zone-aquifer coupling. The underground water environment simulation method based on aeration zone-aquifer coupling comprises the following steps: acquiring environment data of a research area; constructing an aeration zone-aquifer water flow and solute migration and transformation coupling model of the research area based on the environmental data; and according to the vadose zone-aquifer water flow and solute migration and transformation coupling model, determining the underground water environment distribution characteristics and evolution trend of the research area. According to the underground water environment simulation method and device based on aeration zone-aquifer coupling disclosed by the embodiment of the invention, an effective means is provided for accurately judging the pollution path, range and degree of a pollution source to underground water.

Description

technical field [0001] Embodiments of the present invention relate to environmental protection technologies, and in particular to a groundwater environment simulation method and device based on vadose zone-aquifer coupling. Background technique [0002] Groundwater is an important strategic water resource and drinking water source, and its environmental quality is an important guarantee for social and economic development and ecological environment security. In recent years, due to the improper discharge of waste water and waste residues in the production and development of industrial and mining enterprises, the extensive application of fertilizers and pesticides in agricultural production, the leakage of domestic sewage pipe networks and the leaching of landfills and other potential pollution sources, the groundwater environment has become increasingly serious. The risks of pollution and the pressure of prevention and control are enormous. In view of the special occurrence...
