Problems solved by technology

This device is suitable for various states in the soil aerated zone, and is not suitable for the simulation of the artificial coastal zone where the sea, land and water interact, so the influence of seawater and waves on the groundwater in the soil is not considered.

Embodiment Construction

[0027] The technical solution of the present invention is further described below in conjunction with the description of the drawings and specific embodiments as follows.

[0028] The indoor simulation device for the migration and transformation of pollutants in the artificial shore zone is built with a 10mm thick plexiglass plate. The size of the simulation device is: length × width × height = 4.2m × 0.9m × 1.5m. Separate partitions with holes (such as figure 1 shown), the partition is 10mm thick plexiglass (such as Figure 4As shown), one side of the partition is covered with braid, and the whole physical simulation device is divided into three parts: the tank head, the tank body and the tank tail. A liquid level gauge is installed on each side of the device, and the real-time regulation of the lateral water level and water flow rate can be realized by adjusting the height adjustment device under the connector (such as figure 1 shown). Connectors are installed in the flow...

Abstract

The invention discloses 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 interaction of salt water and fresh water realizes 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 a 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 invention belongs to a physical simulation device, and more specifically relates to a physical simulation device for studying the law of pollutant migration and transformation in an artificial coastal zone. Background technique [0002] In the process of global industrial development, the problem of water pollution, especially the serious groundwater and ocean pollution in coastal areas, has become a common concern of the world. Therefore, the study of sea-land-water interaction has been highly valued both abroad and domestically. Environmental pollution under the interaction of sea, land and water is mainly manifested in the salinization of groundwater on land caused by seawater intrusion and the excretion of terrestrial pollutants into seawater through groundwater, resulting in marine pollution. [0003] In my country, in the Bohai Rim Economic Circle dominated by the Liaodong Peninsula, Shandong Peninsula, and Beijing-Tianjin-Hebei region, in t...
