Abstract

The invention relates to the field of simulation test equipment, and discloses a homogeneous vadose zone simulation test device and a homogeneous vadose zone simulation test method. The homogeneous vadose zone simulation test device comprises columns and rainfall simulation devices arranged at the top ends of the columns, wherein the columns are vertically arranged; each column comprises a plurality of barrels which are axially detachably connected; each column has the axial length of 4-6m, and sampling holes are formed in the side wall of each column. In such a manner, when the column is filled with soil into, the barrels can be sequentially filled with the soil from bottom to top and are assembled. The homogeneous vadose zone simulation test method comprises the step of performing a simulation test by using the homogeneous vadose zone simulation test device. In such a way, soil filling operation is easier, and the compacting effect is easier to control; in addition, the longitudinaldepth is 4-6m, close to the thickness of a natural soil cover, so that the natural geological environment of a vadose zone can be better simulated; the rainfall simulation device can simulate a natural rainfall condition and better restore the real environment in the nature, so that overall, the simulation effect is better.

Description

technical field [0001] The invention relates to the field of test equipment, in particular to a simulation test device and method for a homogeneous vadose zone. Background technique [0002] As an important part of water resources, groundwater has the characteristics of wide distribution, good water quality and uniform water quantity. However, with the discharge of industrial "three wastes", the use of chemical fertilizers and pesticides, the leakage of landfill leachate and oil and other organic pollutants, groundwater is easily polluted. [0003] At present, my country's groundwater pollution shows a development trend from point to surface, from shallow to deep, and from urban to rural areas. The scope of pollution is getting wider and wider, and the degree of pollution is getting more and more serious. As the link between the surface and the unconfined aquifer, the vadose zone is not only the necessary place for pollutants to contaminate the unconfined aquifer and the ca...
