Technical field
This utility model belongs to contaminated sites recovery technique field, refers in particular to soil heterotopic drip washing and repairs complete set of equipments
Step gragient elution prosthetic device.
Background technology
Soil is the basic eco-environmental elements constituting natural ecosystems, is also the things depended on for existence and development of the mankind
Matter basis.Along with the mankind's activity aggravation to natural environment influence, produced during people's productive life
Pollutant enter soil possibly through various approach, and exceed receiving and the detergent power of soil, thus lead
Cause soil natural functional disorder and soil quality deteriorates, and then neighbouring human body and surrounding enviroment may be produced
Raw serious harmful effect.Therefore, it is necessary to take rational technological means to carry out contaminated soil remediation, thus
Effectively control health and Ecological Environment Risk that soil pollution causes.
Soil heterotopic drip washing will be transferred in the reactor of ground from contaminated area by contaminated soil, utilizes
Water or other eluent, acted on by chelating, solubilising, precipitation etc., separates soil pollution component or by soil
In pollutant be transferred to liquid phase, then the technology that the leacheate containing pollutant is processed.Soil heterotopic drenches
Washing and belong to physical/chemical recovery technique, the polluter that can be used for processing includes that heavy metal and half volatile are organic
Pollutant, difficult volatile organic contaminant etc., have and effectively reduce soil pollution substrate concentration, flexible operation,
Process control, the advantages such as reparation speed is fast.
According to current existing research and application, soil heterotopic drip washing is repaiied for big particle diameter rank contaminated soil
The most more effectively, the pollutant in gravel, medium-fine sand and similar soil are easier to be cleaned by out, and glue
Property the most difficult cleaning of pollutant in small particle rank soil such as soil.Generally there is soil in existing drip washing equipment
Quality is poor for applicability, it is single to repair pollutant, drip washing device systems is numerous and jumbled, manipulation strength is high, water consumption
And the problem such as displacement is big.
Summary of the invention
Main purpose of the present utility model is for soil heterotopic drip washing in small particle rank soil pollution reparation
On deficiency, it is provided that a kind of can be applicable to different pollutant type, the soil of different-grain diameter rank soil remediation
The Step gragient elution prosthetic device of complete set of equipments is repaired in earth dystopy drip washing.
The purpose of this utility model is achieved in that
The Step gragient elution prosthetic device of complete set of equipments is repaired in soil heterotopic drip washing, including screw classifying mechanism and pouring
Washing repairing mechanism, the concrete structure of described screw classifying mechanism is: include spiral classifier, screw classifying
High-pressure water nozzle is set before the sand return mouth of machine, uses tap water isolated carefully to spiral classifier as water source
Gravel carries out clear water washing, isolated contaminated soil granule via the overfall overflow of spiral classifier to liquid collecting
Groove, the concrete structure of described drip washing repairing mechanism is: include being connected with collecting tank conveying by Pulp pump
Drip washing agitator tank, is provided with blender and can reduce stirring dead angle and strengthen hybrid reaction effect in drip washing agitator tank
Circulation stirring pipe, the delivery outlet of drip washing agitator tank by Pulp pump connect centrifugal dehydrator, at centrifugal masterpiece
Realize soil dehydration under with, can effectively realize the particulate that silty clay class routine dehydration technique is difficult to
The dehydration of soil, the clear liquid delivery outlet of centrifugal dehydrator connects clear liquid collecting tank.
Workflow of the present utility model is as follows:
(1) screw classifying: sieve material and the flushing water of Wet oscillating screen with gravity fall to spiral classifier,
Spiral slowly runs, and is sufficiently stirred for serosity, makes soil constitution connect further with recycle-water (containing eluent)
Touch mixing.Through gravitational settling and screw lifting, the most big and heavy granule is discharged from sand return mouth, the most tiny
Soil particle then from downflow weir overflow.High-pressure water nozzle is set before sand return mouth equally, uses tap water to spiral shell
The rotation isolated granule of grader carries out clear water washing, after being washed by the granule being practically free of polluter directly
Discharge, reduce pending contaminated soil amount further.
(2) drip washing stirring: Soil slurry is delivered to drip washing agitator tank by Pulp pump, stirs in drip washing simultaneously
Adding eluent in groove and be sufficiently stirred for reaction, the selection of eluent type is different according to soil pollution species
And it is different.Drip washing whipping process selects less liquid-solid ratio to reduce the generation amount of wastewater eluting, selects simultaneously
Select the longer time of staying, to overcome the shortcoming that small particle rank soil particle permeability is the strongest, make eluent
Can be sufficiently mixed with pollutant.Drip washing agitator tank is externally provided with circulation stirring pipe except blender, reduces stirring dead angle
And strengthen hybrid reaction effect.
(3) centrifuge dehydration: after scrubbed stirring reaction, soil pollutant has effectively been transferred to liquid from solid phase
Phase, mixing mud delivers into centrifugal dehydrator by Pulp pump, real under the centrifugal action of high speed rotating
Now effective soil dehydration, clear liquid enters subsequent wastewater treatment unit, dehydration earth then can as cleaning soil he
With.Centrifugal dehydrator is selected can effectively to realize the particulate that silty clay class routine dehydration technique is difficult to
The dehydration of soil.
This utility model highlights and useful having the technical effect that compared to existing technology
(1) use wet screening simple, reliable, convenient and screw classifying equipment, by soil constitution according to
Particle diameter makes a distinction, and discharges and is practically free of polluter and through the cobble washed and granule, decreases soil
Drip washing processes total amount, achieves other tiny soil particle in advance simultaneously and (contain with recycle-water in classification process
Eluent) mixed form and time of contact.
(2) sand export at wet screening Yu screw classifying equipment is all integrated with tap water wash mill, permissible
The isolated cobble of the system that realizes and the washing function of granule, effectively remove the trace contaminant of residual on it,
Guarantee Environmental security, decrease the complexity of system simultaneously.
(3) use the drip washing agitator tank of longer residence times, overcome small particle rank soil particle permeability not
Strong shortcoming, makes eluent be sufficiently mixed with pollutant.Drip washing agitator tank is additionally provided with circulation in addition to blender and stirs
Mix pipe, reduce stirring dead angle and strengthen hybrid reaction effect.
(4) centrifugal dehydrator is used to carry out washed off soil dehydration.Poor to filterability, that viscosity is high viscosity great soil group
Soil, centrifugal dehydrator equally realizes fast dewatering.
Therefore, this utility model may be not only suitable for heavy metal and/or the reparation of organic polluted soil and difference
The dystopy drip washing of particle diameter rank soil is repaired, and have applied widely, reduced training good, repairing effect
Stablize, operation runs simplicity, water consumption is little, wastewater recycle rate advantages of higher.
