Embodiment 1

[0042] like Figure 1-Figure 2 , a three-dimensional simulation system for the interception and release of pollutants in the vadose zone, including a test main box 1, an aquifer seepage recharge control system, a vadose zone water distribution and leaching system, and an effluent collection and monitoring system. The test main box 1 Consisting of a box body 12 and a water distribution cover 11 covering the box body 12, the test main box 1 can carry different simulated media in layers, and a plurality of supply ports are uniformly distributed along the horizontal direction under one side wall of the box body 12 13. A plurality of water outlet pipes are evenly distributed in the vertical direction on the side wall of the box body 12 on the opposite side of the feed port 13; the aquifer seepage recharge control system includes an aquifer seepage recharge control box 2, and the aquifer seepage recharge The top of the control box 2 is provided with a water inlet pipe 21, the side w...

Embodiment 2

[0122] like image 3 As shown, further optimization is carried out on the basis of the three-dimensional simulation system for the interception and release test of a pollutant in the vadose zone described in Example 1, the inside of the water distribution cover 11 is hollow, and the water distribution pipe 111 extends to the water distribution cover 11 In the inner cavity, the bottom of the water distribution cover 11 is provided with a water distribution hole 112 communicating with the inner cavity of the water distribution cover 11. In this embodiment, the water distribution is even, and the structure is simple and easy to implement.

Description

technical field [0001] The invention relates to the research field of vadose zone, in particular to a three-dimensional simulation system and a test method for the interception and release test of pollutants in the vadose zone. Background technique [0002] As a natural barrier of aquifers, the vadose zone has attracted attention and related research because of its interception and attenuation of pollutants. The interception and attenuation intensity of pollutants in the vadose zone is closely related to the physical and chemical properties of the vadose zone medium itself and the components and properties of the leachate. At present, the research on the interception and attenuation of pollutants in the vadose zone It is still mainly in the stage of laboratory test and research. In the existing technical field, the interception and release test of landfill leachate pollutants in the vadose zone is a one-dimensional leaching column test. rate and solute gradient changes on t...
