Description
Technical field：
This utility model is related to the device that a kind of utilization plant water suction separates heavy metal in Polluted Soil.
Background technology：
With industrial development, heavy metal pollution is increasingly universal, almost threatens each country.A huge sum of money in soil
Category pollutant major part residues in soil plough horizon, and few movement, difficult degradation, toxicity are big, causes soil once contaminated it is difficult to recover.
And contaminated by heavy metals soil colorless and odorless, it is difficult to be discovered by the sense organ of people, typically to be accumulated into food chain by crop
Just can reflect when tiring out to a certain extent, so heavy metal is the important polluter of a class for affecting ecology erroneous zone.
At present both at home and abroad traditional method such as conventional physics, chemistry and biology controls and administers contaminated soil.Thing
Reason restorative procedure mainly has soil removal and replacement, engineering removal etc..Soil replacement method can effectively reduce impact of the heavy metal to environment, but quantities
Greatly, it is costly, while also certain risk can be produced to environment.Engineering removal method can more thoroughly remove a huge sum of money for contaminated soil
Category, but be suitable only for by heavy metal severe contamination, area it is less and concentrate soil treatment.
Chemical redemption mainly includes that chemistry is fixed, heavy metal-passivated method, by applying modifying agent, such as Calx, fertilizer, Hu
Quick acid etc. changes the valence state or chemical form of polluted heavy metals, and then reduces the transmission to the harm of plant and in food chain,
But the method may destroy biological activity of soil, secondary pollution is easily brought, be only suitable for the process of small area severe contamination soil.
Phytoremediation is using plant the pollutant in soil to be fixed, absorbed, to remove soil environment in dirt
Dye thing makes its harmfulness be minimized or disappear.Phytoremediation is that a kind of reliable, comparatively safe environmental friendliness repairs skill
Art, it is just of interest by countries in the world government, scientific and technological circle, business circles.Be mainly shown as small investment, low cost, economic profit, to soil
Earth environmental perturbation is little, regulation effect permanent, do not destroy treatment of the earth, do not cause secondary pollution, beautification landscape, heavy metal to follow again
Ring and it is partially recycled, using area is big, the later stage processes the aspect such as simple.But phytoremediation technology also has its limitation.Due to
Over-accumulated plant kind is rare in nature, people from the universal relatively low, individuality of super enriching plant Biomass that field screen it is short and small,
Poor growth, and the restriction of the territorial environment condition such as climate, soil, cause that repairing and treating efficiency is low, the cycle is long, constrain big
The application of scale, it is difficult to meet commercial requirements.Super enriching plant repairing heavy metal pollution soil takes oversize, repair coverage and is only capable of
It is confined to scope, heavy metal that root system of plant can extend and there is certain selectivity, is difficult to entirely with a kind of super enriching plant
The all contaminants in soil are removed in face, thus economically might not be quite reasonable.
Utility model content：
This utility model is in order to make up the deficiencies in the prior art, there is provided one kind separates weight in Polluted Soil using plant water suction
The device of metal, its reasonable in design, expense is low, safe and reliable, soil remediation cycle is short, and the removal efficiency of heavy metal is high,
Solve problems of the prior art.
This utility model is that the technical scheme that solution above-mentioned technical problem is adopted is：
A kind of utilization plant water suction separates the device of heavy metal in Polluted Soil, including the sealing coat above Polluted Soil,
Compost is set above sealing coat, and the planting plants in compost, the sealing coat includes upper strata geotextiles, lower floor's geotextiles
And the heavy metal adsorption oxidant layer between upper strata geotextiles and lower floor's geotextiles.
The sealing coat is layed in the groove being located above Polluted Soil.
Anti-seepage geomembrane is provided with below Polluted Soil.
This utility model adopts said structure, reasonable in design, because plant is planted in clean compost, plants
Thing is not contaminated by heavy metals, can trust edible, guarantee ecological safety；The limitation to super enriching plant is eliminated, can be with
Any plant of the suitable local climate of plantation is selected, while not destroying biological activity of soil, heavy metal can be carried from soil
Take out, fundamentally solve heavy metal pollution problem, the removal efficiency of heavy metal is high, and expense is low, safe and reliable, soil is repaiied
Multiple cycle is short.

Specific embodiment：
Clearly to illustrate the technical characterstic of this programme, below by specific embodiment, and with reference to its accompanying drawing, to this reality
It is described in detail with new.
Embodiment 1：
As shown in Figure 1, Figure 3, a kind of utilization plant water suction separates the device of heavy metal in Polluted Soil, including located at Polluted Soil
The sealing coat 7 of 1 top, in the top of sealing coat 7 compost 2 is arranged, and the planting plants 8 in compost 2, the sealing coat 7 includes
Upper strata geotextiles 3, lower floor's geotextiles 4 and the heavy metal adsorption oxidant layer 5 between upper strata geotextiles 3 and lower floor's geotextiles 4.
The heavy metal absorbent of heavy metal adsorption oxidant layer 5 is formulated by ammonium hydrogen phosphate, three kinds of materials of Gypsum Fibrosum and calcium hydroxide, counterweight
Metal has very strong absorption fixation.
The sealing coat 7 is layed in and is located in the groove of the top of Polluted Soil 1.
Using upper strata geotextiles 3 can resist plant root and penetrate, lower floor's geotextiles 4 have good water penetration, are easy to plant
Thing healthy growth and prevent heavy metal from being absorbed by plant root.
The present embodiment structure is applied to the in-situ immobilization of Polluted Soil 1, trench digging in situ is carried out on Polluted Soil 1, by this practicality
New to be layed in ditch, during irrigation, irrigation liquid injects from the upper strata of Polluted Soil 1, with the water sorption of plant, in contaminated soil
Heavy metal ion flows with water, when heavy metal ion moves to heavy metal adsorption oxidant layer 5 through lower floor's geotextiles 4, by a huge sum of money
Category adsorbent is fixed, and water can reach compost 2 by heavy metal adsorption oxidant layer 5, be absorbed by plants.Plant harvest with
Afterwards, sealing coat 7 can be taken out again, therefrom extract heavy metal.
Embodiment 2：
As shown in Fig. 2 the present embodiment is with the difference of embodiment 1：Anti-seepage geomembrane 6 is provided with below Polluted Soil 1.
The present embodiment structure pollutes suitable for showering, and Polluted Soil 1 has been dug, and Polluted Soil 1 has been laid in into antiseepage and has been made
On anti-seepage geomembrane 6, sealing coat 7 is laid on Polluted Soil 1, and compost 2 is laid in the upper strata geotextiles 3 of sealing coat 7,
The cultivated plant in compost 2, during irrigation, irrigation liquid injects from the bottom of Polluted Soil 1, with the water sorption of plant, Polluted Soil
Heavy metal ion in earth flows with water, when heavy metal ion moves to heavy metal adsorption oxidant layer 5, is consolidated by heavy metal absorbent
It is fixed, and water can reach compost 2 by heavy metal adsorption oxidant layer 5, be absorbed by plants.After plant harvest, sealing coat 7
Can again be taken out, therefrom extracted heavy metal.
Above-mentioned specific embodiment cannot function as the restriction to this utility model protection domain, for the skill of the art
