Description
Technical field
The invention belongs to technical field of soil remediation, specifically a kind of ecological type soil restorative procedure.
Background technique
Current heavy metal pollution problem of administering has become a whole world environmental problem urgently to be resolved.Wherein water pollution is main
Refer to water body (including river, lake, reservoir, ocean and industrial water, discharge water and Drinking Water etc.) by heavy metal classes
Pollution of pollutant, including cadmium, lead, mercury, chromium, arsenic etc., pollution source are mainly industrial wastewater, such as dressing plant, electroplate factory, steel
The waste water of the discharges such as factory.
For heavy metal in soil in addition to the heavy metal that itself contains, remaining is then since pollution makes heavy metal enter soil
In.Heavy metal pollution of soil is mainly from various aspects: the sedimentation of heavy metal in atmosphere, for example, industrial production discharge exhaust gas, contain
Lead vehicle exhaust etc., which passes through natural subsidence and drenches with rain, settles into soil；It is irrigated using the sewage containing heavy metal, leads to soil
The increase of earth weight Cd, As, Cu equal size；In addition, the fertilizer and pesticide of the plastic film of daily life, agricultural application also leads to soil
Earth pollution.The recovery technique of common main organic pollutant contaminated soil has biological prosthetic, chemical remediation, peripheral doses etc.,
Chemical remediation has wider applicability, especially suitable for high concentration, multicomponent organic contamination place.
During existing soil remediation, since soil screening is insufficient before elution, so that elution efficiency is lower, consumption is big
Leacheate is measured, while plastic film cannot be effectively removed.
Summary of the invention
In order to make up for the deficiencies of the prior art, during solving existing soil remediation, since soil sieves not before elution
Sufficiently, so that elution efficiency is lower, the problem of consuming a large amount of leacheates, while plastic film cannot be effectively removed, the present invention
A kind of ecological type soil restorative procedure proposed.
The technical solution adopted by the present invention to solve the technical problems is: a kind of ecological type soil reparation of the present invention

Soil to be repaired containing stone is sent into cylinder 11 through feed hopper 13, and soil in soil to be repaired is from elastic rod 3 and steel cable
It is fallen into mesh between 31 in cylinder 11, the stone in soil to be repaired stays in the sieve that elastic rod 3 and steel cable 31 form
Portion；After soil to be repaired sieves completely, the soil separated carries out next stage processing after the collection of discharge port 12,
Stone is left inside the sieve that elastic rod 3 and steel cable 31 form, handle 27 is taken out and rotated clockwise from card slot 29 at this time
It is caught in the card slot 29 of 28 other side of position-arresting disk, transmission of the handle 27 through No. two gears 26, rack gear 25 and ring flange 24, pulls afterwards
No.1 annulus 2, so that elastic rod 3 stretches after restoring to the original state, due to 11 axle center angle with horizontal plane 10-20 degree of cylinder, stone at this time
Opening of the block under the cooperation that self gravity and elastic rod 3 rotate from cylinder 11 close to lower section is discharged, and stone is then transported place
Reason；Be caught in by handle 27 in different U-type grooves 30 can control have between No.1 annulus 2 and No. two annulus 21 it is different away from
From, and then the height that arches upward of elastic rod 3 is controlled, different width of mesh can be obtained in cooperation steel cable 31, to adapt to different
The reparation screening operation of grain diameter soil；When soil to be repaired is in screening process, elastic rod 3 and No.1 annulus 2 and No. two circles
Ring 21 constantly rotates, so that the steel ball 34 in cavity 33 constantly rolls, mutually collision generates vibration between steel ball 34, so that
Elastic rod 3 constantly vibrates, and further increases the screening efficiency of soil to be repaired；Wavy protrusion 35 can increase steel ball 34 and exist
Collision frequency in cavity 33 in rolling process, and then increase the vibration frequency of elastic rod 3, further increase soil to be repaired
Screening efficiency；It drives No. three gears 51 to rotate when rotating by outer tooth disk 22, and then fan is moved by shaft 5 and belt driving band
52 rotations form negative pressure in opening of the cylinder 11 close to lower part, and then to being evacuated in cylinder 11 so that in cylinder 11 to
The plastic film scraps for the lighter weight adulterated in rehabilitating soil are sucked out, and plastic film scraps are after cylinder 11 is sucked out in fan 52
It is adsorbed on steel wire 53, motor 15 stalls after soil to be repaired screening, and staff will be adhered on steel wire 53
Plastic film scraps carry out recycling post-processing, further reduced the impurity content of soil to be repaired.
