Embodiment 1

[0065] This embodiment provides a simulation device for detecting moisture infiltration in the vadose zone, such as Figure 1 to Figure 3 As shown, it includes: a supply unit, a discharge unit, a vadose zone detection unit 6 , a river simulation unit, a vadose zone simulation unit and an aquifer simulation unit. Among them, the river simulation unit, the vadose zone simulation unit and the aquifer simulation unit are arranged vertically from top to bottom. The waste liquid discharged from the river simulation unit and the aquifer simulation unit; the vadose zone detection unit 6 is connected with the vadose zone simulation unit to detect the physical and chemical properties of soil moisture in the vadose zone simulation unit. In this embodiment, tap water is used as the supply liquid, and other water resources such as river water or lake water may also be used to fully simulate the use environment.

[0066] Such as figure 1 As shown, the supply unit includes: a supply box 11...

Embodiment 2

[0089] This embodiment provides a method for detecting and simulating the water infiltration of the vadose zone, using the simulation device for detecting the water infiltration in the vadose zone in Example 1, which includes the following steps:

Abstract

The invention discloses a simulation device for moisture infiltration detection of an aeration zone. The simulation device comprises a supply unit, a discharge unit, a river simulation unit, an aeration zone simulation unit, an aquifer simulation unit and an aeration zone detection unit. The river simulation unit is respectively communicated with the supply unit and the discharge unit; the aeration zone simulation unit is communicated with the river simulation unit; the aquifer simulation unit is communicated with the aeration zone simulation unit, and the aquifer simulation unit is arranged on the other side, opposite to the river simulation unit, of the aeration zone simulation unit; the aquifer simulation unit is also respectively connected with the supply unit and the discharge unit; and the aeration zone detection unit comprises a plurality of detection probes, and the detection probes are connected with the aeration zone simulation unit. Therefore, the migration process of the moisture in the aeration zone in the process in which underground water is recharged by seepage of river water in a real environment is simulated.

Description

technical field [0001] The invention relates to the technical field of experiment simulation, in particular to a simulation device for detecting moisture infiltration in a vadose zone. Background technique [0002] Groundwater is an important source of drinking water in my country, especially in the northern region, where groundwater accounts for more than 70% of the total water supply and is a supporting resource for regional development. In recent years, with the growth of population and the rapid development of social economy in our country, the amount of groundwater exploitation is increasing day by day. On the one hand, the decline of groundwater level directly leads to the decline of the water supply capacity of groundwater sources; on the other hand, when the groundwater level drops seriously, it will further induce environmental geological problems such as land subsidence, seawater intrusion, and water quality deterioration. [0003] With the completion of the middl...
