Row acquisition, probes into Different porosities, difference infiltrates depth, and tailings-water action time is to Infiltration water and tailings sample main component
Transformation degree and tailings in the pollutant vertical process and the regularity of distribution that are discharged into Infiltration water.
Step 3: water-tailings-air interaction scene: in the present apparatus, test cylinder is using upper in simulation aeration zone
The design of end opening achievees the purpose that communicate with outside air, by controlling the size of each sample cock, makes Infiltration water in column
A stable water level is kept in vivo, simulates the environment that water-tailings-air three coexists in the aeration zone of true tailings library, is analyzed
The release process of tailings pollutant in rainfall unsaturation infiltration process.
Step 4: the influence of pollutant release process is infiltrated in groundwater level fluctuation to unsaturation in simulation true environment:
It, can be to groundwater level height in testing column body by adjusting the wriggling pump discharge of sample cock size and rainfall simulator
It is adjusted, probes into different-thickness aeration zone, the influence of middle pollutant vertical release process and degree is infiltrated to rainfall unsaturation.
Example one: the simulation of vertical release process is polluted in certain metallic ore tailings library under rainfall unsaturation Infiltration Condition
Certain metal tail sand storage is the release process for understanding pollutant during tailings is banked up, and has the proposition pollutant being directed to anti-
Prosecutor case carries out the vertical release process of certain metallic ore tailings pollutant under the influence of rainfall unsaturation is infiltrated using the present apparatus.
By gather material, the type, acidity and average annual rainfall of the ground rainfall are analyzed, the dilution heat of sulfuric acid of pH=5.4 is prepared, passes through
Adjusting peristaltic pump and valve flow control unsaturated zone depth is 20cm, and rainfall simulation continues one week, in rainfall, every other day
Water samples all in infiltration process are acquired, analyze its dissolved oxygen content, oxidation-reduction potential, pH value, iron ion, copper from
Son, manganese ion, lead ion, zinc ion, potassium ion, calcium ion, sodium ion, magnesium ion, sulfate ion, chloride ion, carbonate
Ion, bicarbonate ion etc. carry out its mineral Main elements of test analysis to different depth tailings sample after the end of the test,
Obtain rainfall unsaturation infiltration process, water-tailings-air interaction changing on vertical and time dimension to tailings and Infiltration water
Process is made, pollutant is probed into and thinks release time-space process in Infiltration water from tailings.It is set for the prevention and control scheme of tailings library pollutant
Meter provides theoretical foundation.
In short, the present apparatus utilizes rainfall simulation system, different type, pH value, rainfall rainfall are simulated, and uniformly land
Vertical partition is carried out to tailings column, each compartment is carried out to infiltrate water sample and tailings sample in test cylinder to tailings column surface
Acquisition is studied under rainfall unsaturation Infiltration Condition, and water-tailings interaction vertical release process of pollutant to tailings and enters
The transformation effect for the main component that seeps water.Moreover, it is dropped by sample collection system bottom water flow and rainfall simulation system
Rainfall can effectively change water level and infiltration rate in testing column body, probe into level of ground water fluctuation, unsaturated zone depth changes and different
Influence degree of the infiltration rate to the vertical release process of pollutant.
It should be understood that for those of ordinary skills, it can be modified or changed according to the above description,
And all these modifications and variations all should belong to the protection scope of the appended claims for the utility model.
