Description
Technical field
The present invention relates to soil in-situs to repair field, in particular to a kind of method that soil in-situ elution is repaired.
Background technique
With the development of society, people increasingly pay attention to environment, in order to improve environment, restore soil, people's invention
Many methods, wherein the method for just having soil in-situ elution to repair, soil in-situ elution, which is repaired, to be referred to and does not move contaminated soil
Earth directly carries out the soil restoring technology of original place reparation or processing in the position that place is polluted to it, has investment low, right
The small feature of surrounding environment influence, is increasingly taken seriously；
There are certain drawbacks in the method that existing soil in-situ elution is repaired, original position elution technique is more at present when in use
Leacheate is injected by the way of vertical shaft, but is influenced by factors such as soil permeability coefficients, and the radiation scope of vertical shaft is limited, elution
Liquid cannot come into full contact with pollutant, and the effect for eluting reparation is poor；There is application level well to be eluted in other patents of invention
Liquid injection, such mode can increase the contact area of leacheate and pollutant, improve remediation efficiency, but horizontal well construction needs pair
Soil carries out excavation and the pipe laying of large area, and difficulty of construction is big, and complex procedures, project amount is big, and restores ineffective, extensive

60 °, ultrasonic generator is arranged at 0.8-1.2 meters of the inner distance bottom end of inclined shaft, and inclined shaft is symmetrical arranged in contaminated soil.
Preferably, it in the step (4), elutes 2.5-3.5 hours, elutes 2-3 times.
Preferably, in the step (5), the ultrasonic generator starting time is located at the 0.5-1.0 hour after elution starts
Afterwards, the frequency of ultrasonic generator is 20-30kHz, and the starting in 15-20 minutes of ultrasonic generator interval is primary during elution, is surpassed
Generating device each run 10-15 minutes.
Preferably, in the step (6), in the extraction well course of work, when extracting system vacuum control -0.060~-
0.070MPa, the well head vacuum degree control of extraction well is in -0.025~-0.035MPa.
Preferably, in the step (7), the waste liquid and exhaust gas of extraction are sent into devil liquor recovery processing unit and exhaust-gas treatment dress
It sets, waste liquid is again introduced into elution circuit, exhaust gas warp by eluent injection device after the processing of devil liquor recovery processing unit is up to standard
Discharge, avoids secondary pollution after emission-control equipment processing is up to standard.
Compared with prior art, the invention has the following beneficial effects: the method that a kind of soil in-situ elution is repaired,
1, eluent is injected by the way of inclined shaft, slope construction is simple compared with horizontal well, without the soil for carrying out large area
It excavates, reduces the cost that soil in-situ elution is repaired；And inclined shaft fluid injection can also make that the diffusion zone of eluent is bigger, allows
The contact area of soil and leacheate is wider, to reinforce the repairing effect of soil in-situ elution；
2, ultrasonic generator is added in inclined shaft in soil in-situ elution repair process, ultrasonic generator can produce
Raw cavitation effect, high radiation pressure harmony miniflow strengthen elution effect jointly, and cavitation effect refers to the high-pressure shocking wave of ultrasound generation
Soil particle can be smashed, eluent is promoted to enter inside soil particle and play a greater role, the high speed that cavitation effect generates
Microjet can be rinsed contaminated soil, and furthermore radiation pressure harmony miniflow can increase disturbed soil surface diffusion layer, promote
Friction and stirring between soil particle make eluent diffuse into the desorption given full play in soil aperture to pollutant and make
With to accelerate the effect and rate of elution, and relatively simple for structure, the operation of the method for entire soil in-situ elution reparation
More convenient, using effect is more preferable relative to traditional approach.
