Abstract
The invention relates to the technical field of simulation test, and discloses a simulating experiment device and method for a layered aeration zone. The simulating experiment device for the layered aeration zone comprises a column body and a rainfall simulating device, wherein the column body is arranged on a base; the rainfall simulating device is arranged at the top end of the column body; thecolumn body is vertically arranged, and comprises a plurality of cylinders which are detachably connected along the axial direction; the axial length of the column body is 4 to 6m, and sampling holesare formed in the side wall of the column body, so that when the soil is charged into the column body, the soil can be sequentially charged into each cylinder from bottom to top, and the cylinders canbe assembled. The simulating experiment method for the layered aeration zone adopts the device to perform simulating experiment; the multiple auxiliary soil columns containing different particles arefilled inwards; the soil charging is easier, the tampering effect is easy to control, and the longitudinal depth is 4 to 6m and is approximate to the thickness of a natural soil coverage layer; the rainfall simulating device can be used for simulating the natural rainfall condition, the real environment of the nature can be well restored, and the simulating experiment is more precise in overall.
Description
Technical field [0001] The present invention relates to the field of test technology, and in particular to a simulation test device and method for a layered vaulted zone. Background technique [0002] As an important part of water resources, groundwater has the characteristics of wide distribution, good water quality and uniform water volume. However, with the discharge of industrial "three wastes", the use of chemical fertilizers and pesticides, the leakage of organic pollutants such as landfill leachate and petroleum, groundwater is easily polluted. [0003] At present, my country's groundwater pollution has shown a trend of development from point to surface, from shallow to deep, from urban to rural, and the scope of pollution is becoming wider and more serious. Vadose zone, as the link between the surface and the diving aquifer, is not only the necessary place for pollutants to pollute the diving aquifer and the carrier of pollutant migration and transformation, but also the m...
