Abstract
The present invention relates to a kind of dystopys suitable for clayed soil pollution amelioration to elute prosthetic device and restorative procedure.Prosthetic device includes the soil particle diameter classification being made of wet crusher, collection stock tank, roller solution mud machine, Wet oscillating screen, collecting tank etc. and slurrying unit, the elution be made of elution slot, mud concentration basin, centrifugal dehydrator etc. and dewatering unit；The treatment unit for waste water that pond, effluent settling chamber etc. form is combined by waste water reaction, the sludge treating block being made of sludge storage pool, filter press etc.；It further include the constant pressure water supply unit and medicament configuration unit of auxiliary.Restorative procedure includes broken, slurrying, screening, elution, concentration, dehydration and matched wastewater treatment, Treatment of Sludge, water supply and dosing.Dystopy elution prosthetic device and restorative procedure are primarily adapted for use in each heavy metal species including clayed soil, organic or combined contamination soil reparation, have the advantages that applied widely, repairing effect is stable, operation operation is easy, wastewater recycle rate is high.
Description
Technical field
The invention belongs to contaminated sites recovery technique fields, and in particular to a kind of to can apply to including clayed soil
Each heavy metal species, organic or combined contamination soil reparation dystopy elution prosthetic device and restorative procedure.
Background technique
Soil is the basic eco-environmental elements of composition natural ecosystems and the substance base that the mankind depend on for existence and development
Plinth.Aggravation with mankind's activity to natural environment influence, produced pollution object is possible to logical during people's production and living
Cross various approach and enter soil, and be more than the receiving and detergent power of soil itself, so as to cause soil natural functional disturbance with
And the soil contamination problem that soil quality deteriorates, and then serious adverse effect may be generated to neighbouring human body and surrounding enviroment.
Therefore, it is necessary to take reasonable technological means to carry out contaminated soil remediation, to effectively control human body caused by soil pollution
Health and Ecological Environment Risk.
It is to dig out contaminated soil from contaminated area and be transferred to neighboringly that soil heterotopic, which elutes recovery technique,
In point or reactor, using water or other eluents, increased by grading, acidification dissolution, organic chelated or surfactant
The effects of molten, separates serious pollution soil constitution or the pollutant in soil is transferred to liquid phase from solid phase, then to containing pollutant
The soil restoring technology that is handled of leacheate.Soil heterotopic elution belongs to physical chemistry recovery technique, can be used for handling
Polluter includes heavy metal and half volatile organic contaminant, difficult volatile organic contaminant etc., has flexible operation, process
Controllably, the advantages that speed is fast, and soil whereabouts is extensive after reparation is repaired.
However, traditional soil heterotopic elution means are dirty for big partial size rank according to existing research and application at present
The reparation more economical and effective of soil is contaminated, the pollutant in gravel, sand, fine sand and similar soil is easier cleaned come out
And rehabilitation cost is controllable, and the then more difficult cleaning of the pollutant in the clayed soil of the small particles rank such as silty clay or clay, and
Rehabilitation cost is higher.It is reached generally, for particulate in soil (generally referring to powder/clay of the partial size less than 63-75 μm) content
The clayed soil even higher to 25%~30%, the effect and cost of traditional soil heterotopic elution all no longer have advantage.
Therefore, it is necessary to develop a kind of economical and effective, the dystopy of safety and stability elution reparation side for clayed soil pollution
Method and device.
Summary of the invention
It is an object of the invention to be directed to deficiency of the existing soil heterotopic elution technique on clayed soil pollution amelioration, mention
Prosthetic device and restorative procedure are eluted for a kind of dystopy suitable for clayed soil pollution amelioration.
The present invention can be realized by the inclusion of the technical solution of following steps:

Large granular impurity and little particle impurity after washed can direct safe utilization, without being further processed.
(4) dosing elution technique is used.The homogenization mud of screened decrement fills in elution slot with corresponding eluent
Divide haptoreaction, soil pollutant is separated from soil particle solid phase and is entered in leacheate, realizes pollutant really from soil
The reparation purpose removed in ontology subtracts better than the contaminated soil in common soil Ex-situ washing remediation based on sieve classification
Hold technique.
(5) gravity concentration and centrifugal dewatering technology are used.The mud of completion elution reaction first forms after gravity concentration dense
Contracting mud, then soil water desorption is carried out by centrifugal dehydrator.Compared with other dewatering process, gravity concentration pretreatment is substantially reduced
The hydraulic loading of subsequent mechanical dehydration, and the dewatering of mud is improved, after mechanical dehydration soil moisture content is lower.This
Outside, centrifugal dehydration has many advantages, such as to continuously run, interval is rinsed and washing water quantity is few, charging moisture content tolerance is high, and
Under the conditions of the feed mud of special properties (particle diameter distribution, partial size density etc.), exists and do not have to add flocculation medicament is quenched to obtain
A possibility that obtaining preferable centrifugal dehydration effect.
(6) waste water treatment, recovery and utilization is used.The pollutant that wastewater treatment will remove out out of soil particle in leacheate
Again solidification generates precipitating (heavy-metal contaminated soil) or direct oxidation degradation (organic material contaminated soil), and treated, and waste water can
Fully recovering does not generate efflux wastewater when soil slurrying, normal operation.
