Embodiment 1

[0025] See figure 1

[0026] An experimental device for simulating the migration of soil pollutants and soil remediation, comprising a box body 10, a liquid input device 20, a vertical sampling device 30, and a horizontal sampling device 40. The vertical sampling device 30 is distributed on the outer wall of the box body 10 and penetrates the Casing 10 stretches into 5 sampling pipes inside it, and the sampling port 31 of sampling pipe is positioned at different vertical height intervals of 50 centimeters in casing 10; Described horizontal sampling device 40 is 5 extraction water sleeve pipes; A filter medium layer 11 is fixed around and at the bottom of the casing 10, which is a 1 cm thick quartz sand filter layer. The filter medium layer 11 is spaced apart from the inner wall of the casing 10 by a certain distance such as 30 centimeters to form a transverse flow compartment 12; There are 6 to 8 stripping coil interfaces 13 in the medium layer on the bottom side of the body ...

Embodiment 2

[0031] See figure 1

[0032]An experimental device for simulating the migration of soil pollutants and soil remediation, comprising a box body 10, a liquid input device 20, a vertical sampling device 30, and a horizontal sampling device 40. The vertical sampling device 30 is distributed on the outer wall of the box body 10 and penetrates the Casing 10 stretches into 5 sampling pipes inside it, and the sampling port 31 of sampling pipe is positioned at different vertical height intervals of 60 centimeters in casing 10; Described horizontal sampling device 40 is 8 extraction water sleeve pipes; A filter medium layer 11 is fixed around and at the bottom of the casing 10 as a filter cloth, and its aperture is 200 meshes. The filter medium layer 11 is spaced apart from the inner wall of the casing 10 by a certain distance such as 30 centimeters to form a transverse flow compartment 12; There are 6 to 8 stripping coil interfaces 13 in the medium layer on the bottom side of the body...

Abstract

The invention relates to an experiment apparatus simulating soil contaminant migration and soil remediation and an experimenting method. The apparatus comprises a tank, a liquid feeding device, vertical sampling devices and horizontal sampling devices. The vertical sampling devices are sampling pipes distributed on the outer wall of the tank and penetrating into the tank. Sampling ports of the sampling pipes are at different vertical heights in the tank. The horizontal sampling devices are a plurality of water extracting casing pipes. The apparatus and the method achieve comprehensive simulation of horizontal-flow and vertical-flow soil contamination leaching experiments. In addition, simulation of soil contaminant migration and simulation of soil remediation are achieved on the one apparatus.

Description

technical field [0001] The invention relates to an experimental device and an experimental method for simulating the migration of soil pollutants and soil restoration. Background technique [0002] Among various soil pollution remediation technologies, the remediation methods of contaminated soil can be classified into in-situ remediation and ex-situ remediation according to the place where the remediation takes place. Technologies for treating pollution sources include bioremediation, phytoremediation, bioventilation, natural degradation, biocomposting, chemical oxidation, soil leaching, electrodynamic separation, air lift technology, heat treatment, excavation, etc.; It must be considered comprehensively according to the characteristics of the contaminated soil and the surrounding environmental factors, and there are many factors to be investigated in the comparative experiment of the contaminated soil remediation process.
