Application method of indoor simulation device for migration and conversion of pollutant in artificial shore zone

Abstract

The invention discloses an application method of an indoor simulation device for the migration and the conversion of pollutant in an artificial shore zone. According to the invention, in the lateral supply direction of a three-dimensional seepage groove, ground water is supplied on one side where a stream flows to simulate the boundary condition of the groundwater flow in a field zone; reasonably proportioned solution is supplied on the other side to simulate the seawater in a coastal zone; and the interaction of salt water and fresh water realizes the real simulation of seawater and terrestrial water. By adopting the device provided by the invention, the physical simulation of the artificial shore zone is simulated to the greatest extend, a large-scale artificial coastal zone is downsized to a small-scale indoor physical simulation device under the guidance of geometric similarity theory, the comprehensive influences of adjustable water level height, saltwater and fresh water interaction, waves, rainfall and external contamination are comprehensively considered, the real simulation of the artificial coastal zone is ensured, and a foundation is laid for the numerical simulation of the artificial coastal zone and the late pollution abatement.

Description

technical field [0001] The patent of the invention relates to a method for studying the migration law of characteristic pollutants in artificial shorelines by using an indoor simulation device for the migration and transformation of pollutants in artificial shorelines. More specifically, it is a method for coupling experimental data and numerical simulation to study characteristic pollutants in artificial shorelines. How to use the migration rule. Background technique [0002] The coastal area has always been the most active area of ​​human economic activities and social activities. In order to solve the contradiction between regional development and land shortage, there has been an upsurge of land reclamation from the sea. An important point that distinguishes the beach aquifer from the inland aquifer is that the beach aquifer is located at the junction of water and land, and various physical, chemical, and biological factors interact, making the beach area a complex, nonli...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to overcome the deficiencies of the prior art, and adopt the artificial shore zone formed by land reclamation, resulting in an increase in the proportion of the artificial shoreline, changing the original natural features, and changing the balance of sea-land water exchange, which may lead to seawater intrusion , Land pollutants enter the ocean to pollute the marine environment and other serious problems
