The bottom wall of also spacing the first container (6) is provided with separation partition (18) in de- chamber (11), and the separation partition (18) is mesh plate,
The separation partition (18) is horizontal in first elution chamber (11).
5. a kind of multistage repair system of metallic pollution soil according to claim 1, it is characterised in that: the jet stream group
Part (14) includes jet pipe (22), slush pump (23) and connecting tube (27), and the feed inlet of the slush pump (23) passes through connecting tube
(27) it is connected to the second discharge port (10) of the second elution chamber (12), the discharge port of the slush pump (23) is in jet pipe (22)
One end connection, and the other end of the jet pipe (22) penetrates to third from the bottom wall of third elution chamber (13) and elutes chamber (13)
Interior, mud passes through jet pipe (22) the upward high-speed jet in the reparation agent solution in third elution chamber (13).
6. a kind of multistage repair system of metallic pollution soil according to claim 5, it is characterised in that: further include siphon
It manages (20), the siphon pipe (20) is the pipe structure of both ends open, and one end spacing of the siphon pipe (20) is set in jet stream
The outside of (22) is managed, and the bottom end port spacing of the siphon pipe (20) is arranged in the bottom wall of third elution chamber (13), and described
The other end of siphon pipe (20) is extended upward, and the top of the siphon pipe (20) buries and overlays on the molten of third elution chamber (13)
In liquid；The bottom end port spacing setting of the siphon pipe (20) is below the discharge port of jet pipe (22), the siphon pipe (20)
Form siphon jet inlet (24) with the bottom wall of third container (8), the wall bodies of the siphon pipe (20) and jet pipe (22) it
Between spacing formed siphon passage (25)；Mud is in the state of jet pipe (22) high speed outflow, swiftly flowing mud solution
So that siphon passage (25) generates siphonage, draws third and elute the settled mud in chamber (13) interior bottom from siphon passage
(25) it is again introduced into siphon pipe (20) upward jet stream and is reacted with repairing agent solution and coming into full contact with.
7. a kind of multistage repair system of metallic pollution soil according to claim 1, it is characterised in that: the broken dress
Setting (1) includes bracket (32), the mechanism that impulses (31), sieve (30) and feed hopper (33), and the feed hopper (33) is upper and lower ends
The ring bodies structure of opening, the sieve (30) is horizontal between the feed hopper (33), and the feed hopper (33) is by impulsing
Mechanism (31) is arranged on bracket (32).
8. a kind of multistage restorative procedure of metallic pollution soil according to any one of claims 1 to 7, it is characterised in that:
The following steps are included:
S1: the soil particle after preliminary broken and removal of impurities is poured into feed hopper (33), and is made by the mechanism that impulses (31)
It is fallen in the inner cavity that soil particle passes through the backward the first container (6) of sieve (30) in little particle dispersed；Fall within the first elution
Soil particle in chamber (11) sufficiently with repair agent solution neutralization reaction, and form mud solution；
Disturbing rod (16) high-speed rotation in S2: the first elution chamber (11) disturbs solution, and mud solution is made to form circinate, mud
Starch solution under the influence of centrifugal force, mud solute precipitates and gathers to the bottom side of the first container (6)；And by separation every
The beds of precipitation of the disturbance layer and lower part of the mud solution layering lower part of disturbance, precipitated mud are passed through the first discharging by plate (18)
Mouth (9) flowing into the second elution chamber (12)；
S3: the mud flowed into the second elution chamber (12) is collected at the bottom of second container (7), passes through guide face in mud
(150) when on, mud solute elutes the renovation agent solution reaction in chamber (12) with second again；
S4: slush pump (23) extracts mud out of second elution chamber (12) by connecting tube (27), and mud passes through jet pipe
(22) the upward high-speed jet in the reparation agent solution in third elution chamber (13), mud and third elution chamber (13) after jet stream
Interior reparation agent solution sufficiently reacts, mud flow up after under the action of the resistance of aqueous solution and self weight, it is final to decline
It is deposited in the bottom of third elution chamber (13)；
And simultaneously, for mud in the state of jet pipe (22) high speed outflow, swiftly flowing mud solution makes siphon passage
(25) siphonage is generated, the third elution settled mud in chamber (13) interior bottom is drawn from siphon passage (25) and is again introduced into rainbow
It upward jet stream and comes into full contact with and reacts with agent solution is repaired in suction pipe (20)；So that the mud circulation in third elution chamber (13)
Reciprocal flowing.
