Embodiment 1

[0045] Example 1: A mobile simulation platform integrating migration, transformation and final destination of groundwater pollution.

[0046] The integrated mobile simulation platform for groundwater pollution migration, transformation and final destination of the present invention includes four parts: a migration and transformation simulation device, an aeration device, a rain simulation device, and a central control computer.

[0047] Such as figure 1As shown, the main body of the migration and conversion simulation device is a rectangular box 1 with an open top, and the box 1 is made of a 10mm thick plexiglass plate, and the periphery of the plexiglass plate is reinforced and supported by a stainless steel square tube. On the inside of the front wall panel and the rear wall panel of the box body 1, there are several upright concave slots (Fig. 2) at a distance of 100mm. The upper edge of the groove 11 is flush with the upper mouth of the casing 1 . A rectangular porous wa...

Embodiment 2

[0061] Example 2: The integrated simulation experiment method of groundwater pollution migration, transformation and final destination.

[0062] This example is carried out on the groundwater pollution migration transformation and final destination integrated simulation platform described in Example 1, specifically including the following steps:

[0063] 1. Collect soil samples layer by layer on the aerated zone soil layer and saturated water zone soil layer of the geological profile of the studied watershed. After refining and drying the collected soil samples, according to the geological structure relationship corresponding to the collection site , soil samples are evenly filled layer by layer into 2~3 sample spaces at both ends of the box; the thickness of the same layer of soil samples filled in each sample space is basically the same, and they are at the same height of the box Above; the total filling height of the soil sample is 50mm lower than the upper opening of the b...

Abstract

The invention relates to an integrated movement simulating platform and a simulating and testing method for migration, transformation and a final destination of groundwater pollution. The simulating and testing method comprises the following steps: firstly arranging the movement simulating and testing platform; then filling an aeration zone for simulating a typical hydrogeological unit, aquifer mediums and pollutant repairing mediums for simulating a typical permeable reaction barrier; finally performing a simulation experiment of the migration, the transformation and in-situ repair of the groundwater pollution on the simulating and testing platform. According to the invention, in order to satisfy the need for different experiment procedures, the pollutant entering the simulating and testing platform can be simulated in various manners, the simulation of a persistent pollution source or a provisional pollution source and the simulation of point source pollution or non-point source pollution are realized, and the whole process that the simulated pollutant penetrates through the aeration zone from the earth surface, enters into an aquifer and realizes the migration and the transformation in the aquifer can be clearly observed; the simulation of the migration, the transformation and the in-situ repair of the pollutant in the typical hydrogeological unit can be realized.

Description

technical field [0001] The invention relates to a groundwater pollution restoration simulation experiment device and method, in particular to a mobile simulation platform and a simulation experiment method integrating migration, transformation and final destination of groundwater pollution. Background technique [0002] As the impact of human activities on the living environment continues to increase, especially due to the development of industries such as metal mining and smelting, chemical industry, printing and dyeing, groundwater quality in some areas of my country exceeds Class IV or Class V, and its main pollution factor is " "Three nitrogen", heavy metals and organic pollutants, etc. According to the "National Groundwater Pollution Prevention and Control Plan (2010-2020)" data show that 90% of my country's urban groundwater is polluted by toxic pollutants to varying degrees. Therefore, the quality of my country's groundwater environment cannot be tolerated. optimism. A...
