Table is enriched on evaporating film, to achieve the purpose that remove pollutant in soil.In the lesser situation of top layer soil moisture ratio
Under, the water that can be migrated also can be less.Although having the supply of underground water, the process of cleaning can also be dragged longer.
The water content for improving top layer soil is undoubtedly the mode for accelerating this process, concentrates on pushing up especially for pollutant
It is even more so in the case where layer soil.Horizontal flood pipe concentrates on superficial layer aiming at pollutant, and Surfaces soil water content
A kind of method of few situation design.In fact, as long as conditions permit, increases the aqueous of topsoil using horizontal flood pipe
Amount is all a method for accelerating scale removal process.
Since under the action of capillary force, the moisture in soil is intended to migrate in fine grain soil.This migration
Situation is significant adverse to the pollution in cleaning coarse granule.It is suitably filled the water into soil, the water of injection can be under gravity
It is first into the preferable coarse granule of permeability.Thus the movement for water in soil provides one from water filling port to thick

Water installations.Water filling device can increase the water content of topsoil, and capillary evaporation film is enable more effectively to play cleaning soil
The effect of middle pollutant.Specifically, the water source in the utility model has the function of providing the utility model water, has simultaneously
Have and increases stressed function.Filter has the function of preventing fine particle in water to pass through.Flow control valve has control water
The function of handling capacity is flowed, flow control valve can be manually controlled manually, can also be automatically controlled with program control device.Soil
Moisture content sensor has the function of monitoring the content of the moisture in its surrounding soil, and soil water content sensor is by signal
It is transferred in the reception device with visual interface, soil water content can be read (the reception device with visual interface

It sets with the function of controlling flow control valve according to the signal of soil water content sensor.Source of additive then has and makes to inject
Water in containing change soil in soluble matter chemical active ingredient.
When using the water filling device of horizontal distribution, the utility model first infused level before being laid with capillary evaporation film
Water pipe is embedded in the depth according to the setting of soil pollution situation, this depth is typically somewhat deeper than the depth that soil pollutant reaches
Degree.To avoid capillary force by contaminated zone to soil deep.On this basis, can be according to the requirement of cleaning work decision
No further installation soil water content sensor.The position of this sensor should select more sensitively react water filling
Influence of the variation of pipe water to the entire change of soil moisture content in water injection pipe coverage.Under normal circumstances, it should be
Between two horizontal flood pipes, depth is between horizontal flood pipe and earth's surface capillary evaporation film.
When using the water filling device of vertical distribution, the utility model first will be infused vertically before being laid with capillary evaporation film
Water pipe is embedded in the depth according to the setting of soil pollution situation, and the maximum water outlet of depth is typically somewhat deeper than soil pollutant and reaches
The depth arrived.To avoid unsaturated water in the case where capillary force acts on or oversaturated bulk water by contaminated zone to soil deep.
When pollutant distribution is deeper in the soil, vertical water injection pipe can install several water outlets positioned at not by boundling on the same position
With the water injection pipe of depth.As the Moisture Movement of deep pollutant migrated upwards is to soil superficial part, positioned at deep
After pollutant in soil is removed, the water injection pipe water outlet of big depth stops water filling, is substituted for the lesser water injection pipe of depth
Water outlet water filling.In other words, water outlet depth can change, high saturation as pollutant bottom boundary is migrated to earth's surface
Soil water supply band gradually to earth's surface migrate, thus gradually shorten soil moisture migration approach, accelerate cleaning process.?
In this foundation pollution cleaning mechanism, installation soil water content sensing can be decided whether according to the requirement of cleaning work
Device, and in water filling tube opening in the case where different depth, if needs install soil water content in different depth
Sensor.The position of this sensor should select to influence model to water injection pipe in the variation that can more sensitively react water injection pipe water
Enclose the influence of the entire change of interior soil moisture content.Soil moisture sensor on different depth can further reflect unearthed
Variation of the moisture on vertical in earth, to be able to more accurately control the water injection rate of water injection pipe.
After laying water injection pipe, sensor and capillary evaporation film, the cleaning key of pollutant in soil is pair
The control of water injection rate.Because very few water cannot make full use of capillary water caused by the evaporability of earth's surface to migrate, Bu Nengyou
Effect utilizes the increased ability of water filling institute.Meanwhile the bulk water water shortage of generation also results in dirt contained in coarse-particle bed
Dye object cannot be cleared up effectively.Hypervolia, which then will lead in soil, forms apparent saturated zone, the moisture meeting in soil
Downward migration is generated under the influence of gravity, so that pollutant be made to migrate downwards, leads to contamination.It is not difficult to find out that water filling
Amount should generate small-scale bulk water in water outlet, and the range of this bulk water should be not move downward significantly as degree.
According to the requirement of pollution condition and cleaning work, three kinds of different water injection rate control modes can be taken:
1) simple control water filling: under this control method, soil water content sensor only install a few or
It does not install.Water filling water is substantially estimated according to evaporation capacity.Expand in view of moisture will lead to pollution in soil shallow-layer supersaturation
It dissipates, under this control method, water injection rate will substantially be controlled in conservative one side.Another side there are the leeway for filling part is exactly
The ability that cannot effectively can be provided using water filling.
2) it manually controls water filling: flow control valve is manually adjusted according to the instruction of soil water content sensor.It is this
Mode can have more fine control to the water of water filling, can satisfy the requirement under normal circumstances to cleaning work
3) automatically control water filling: according to the signal of soil water content sensor, using program control device to water filling water into
Row real-time control.This control mode can utilize water filling bring benefit to greatest extent.But cost is also correspondingly improved
Very much.
In addition, water filling while be added additive in the case where, to the control of additive dosage should with to water injection rate
Control linkage.
Compared with prior art, the utility model has the following beneficial effects:
Since the utility model is simply by the capillary force of naturally occurring in soil, soluble matter in original soil is changed
The approach of migration is enriched in the soluble matter in soil on capillary film, to achieve the purpose that remove pollutant in soil.With it is existing
There are the various methods for removing pollutant in soil to compare, the soil remediation system described in the utility model based on capillary evaporation film
Simple with application principle, structure is simple, and installation is easy, and operating cost is low, provides one kind to remove the pollutant in soil
Economically viable administration way.
In short, the utility model provides a kind of soil remediation system based on capillary evaporation film, soil table can be blocked
The natural evaporation of layer acts on and occurs that this evaporation on the capillary evaporation film of the utility model, makes with soluble matter
Moisture in soil takes soluble matter out of soil enrichment on described evaporating film, to remove pollutant present in soil.
And by the control of water injection rate, environmental protection and energy saving and the improvement of soil pollutant can be better achieved.
