Embodiment Construction

[0034] The device will be further described through specific embodiments below in conjunction with the accompanying drawings.

[0035] In order to prevent the leakage of pollutants and the corrosion of the reactor, and consider the high pressure of the filling soil on the device, the frame of the trial reactor (tank) is made of thick stainless steel plate (340 stainless steel). The two sides of the internal water flow direction of the reactor are respectively covered with perforated steel plates (one side of the steel plate is filled with woven bags to prevent soil particles from seeping out, such as Figure 4 As shown) to block water seepage, this is equivalent to having a water tank for the upstream and downstream, which is convenient for controlling the water level of the upstream and downstream. Three water level observation connectors are respectively arranged on the side, middle and downstream of the reactor, through which the groundwater level at various positions along...

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...
