Extraction liquid in water pipe, the killer injecting pump are the pumping liquids into collector pipe.The collector pipe into contaminated soil for conveying
Leacheate or extracting leacheate.
Preferably, one end of the collector pipe is fixed on water header side wall and is connected to the water header, described
Collector pipe is connected to the extraction pump by one end of the water header, and the collector pipe is another by the water header
End is connected to the killer injecting pump.
The water header that this place discloses realizes that the liquid in pipeline exports at one end, realizes in the other end by liquid ingress pipe
In road.When closing extraction pump, it is positive pressure in water header under the working condition after opening killer injecting pump, liquid flow direction is pushed to catchment
Pipe；When closing killer injecting pump, under the working condition after opening extraction pump, it is negative pressure in water header, pushes liquid from collector pipe stream
To water header.
Preferably, pressure gauge and flowmeter are equipped in the water header.
The press machine and flowmeter that this place discloses are respectively used to export or show the liquid pressure in water header outward
Power and flow.
Preferably, one end that the collector pipe is connected to the water header sets valve, and the collector pipe is at least two.
The valve that this place discloses is used to control the connection and closing between water header and collector pipe.
Preferably, the outlet of the extraction pump is to sewage disposal device.
For the sewage disposal device that this place discloses for liquid derived from the innoxious outlet from extraction pump, concrete model can be according to
It is determined according to the property and process requirements of pollutant.
It additionally provides a kind of contaminated soil and builds heap pumping-note combination restorative procedure, heap pumping-note is built using above-mentioned contaminated soil
In conjunction with prosthetic device, the steps include:
For build heap contaminated soil build heap trench bottom and side wall laying antiseepage film；
Contaminated soil is built into heap in building heap slot, builds the extraction well set in the soil body of heap for plugging collector pipe；
Killer injecting pump is opened to inject leacheate to the soil body by collector pipe；
Killer injecting pump is closed, opens extraction pump to extract the intracorporal leacheate of soil out by collector pipe.
Building heap slot can be the hole excavated on place, its depth can be 1-3m when using in lesser range,
Building heap slot bottom and can beating area is 100-600m2, surrounding side wall can natural discharging slope, the gradient may be configured as 1:1-1:2.Antiseepage film knot
Structure composition can be geotextiles, HDPE film individually or its combine the membrane structure with antiseepage function.
After the leacheate extraction that this place discloses, the step of carrying out injection leacheate and leacheate extraction can be recycled, to protect
Card elution effect reaches requirement.
Preferably, the extraction well wall surface is kept by screen casing.
Preferably, the screen casing successively wraps up strainer, nylon mesh from the inside to the outside.
The extracting well depth and diameter need to meet the needs of extracting and injection, can choose diameter in application and are
The technique of 2-4cm, for the disengaging of leacheate, sieve diameter can be selected as 6-10mm for the sieve pore of the screen casing of support wall in order,
Pitch-row is 40mm ± 10mm.Screen casing outsourcing strainer, strainer can use woven cloth, and it is big compared with woven cloth that one layer of mesh is wrapped in outside again
Nylon mesh.
Preferably, above-mentioned valve and collector pipe quantity are also used, during injecting leacheate and leacheate is extracted out,
By controlled valve adjacent collector pipe is staggeredly worked.
The adjacent collector pipe that this place discloses, which interlocks to work, refers to that another party closes valve when adjacent side output or input
Door stops working；When an adjacent side, which closes valve, to stop working, another party exports or inputs.
Preferably, the spacing between the extraction well is 1.0-1.5m.
Specifically spacing setting is determined according to requirements such as the porosity of soil and techniques, to guarantee elution and extract complete
It is whole.
By installing one Guan Shuanyong of collector pipe, the investment and installation workload of extracting, injection device are reduced.
Device whole installation is convenient in the setting of water header, to further decrease the setting quantity of extraction pump and killer injecting pump
Demand.
The setting of pressure gauge and flowmeter observes injection flow, pressure and the extracting negative pressure of extraction well, to make to fill in real time
It sets and is able to achieve precise manipulation.
The limitation of the quantity of valve and collector pipe realizes the switching to extracting, function of injecting, in conjunction with extraction pump and killer injecting pump
It uses, realizes and extracting, injection are realized to specific region.
The setting of sewage disposal device is so that the pollutant extracted is able to achieve purification, to allow the liquid of discharge can be into
Row recycling.
The setting of antiseepage film avoids secondary pollution of the repair process to surrounding soil and groundwater environment.Extraction well in the soil body
Setting, convenient for plugging for collector pipe, while reducing the possibility that collector pipe is blocked.
Screen casing realizes that the surrounding soil of extraction well is stablized, while facilitating the formation of extraction well.
Two layers of mesh construction outside screen casing, further filters out solid matter, collector pipe is avoided to be blocked, while its two-layer structure
Middle outer layer large-mesh filters out bulk particle, reduces the filter pressure of inner filter screen, promotes its service life.
Adjacent collector pipe staggeredly works, and when collector pipe is according to column discontinuous operation, is able to achieve and is separately injected into construction, individually extracting
Construction and pumping combine construction, are promoted and further promote elution effect.
The setting of extraction well spacing, it is ensured that extraction well setting rationally, elution efficiency caused by avoiding spacing narrow or being wide is low,
Waste leacheate, partial region elute situation not in place.
The beneficial effects of the invention are as follows by the way that leached soil solutions are extracted out and injected, reaches efficient washed off soil, goes to decontaminate
The purpose of object is contaminated, elution equipment investment is reduced.
