Abstract
The utility model discloses a kind of agitating devices of in-situ remediation soil polluted by heavy metals solidification and stabilization, contaminated soil after screening is placed in feed inlet, it is transmitted by crawler belt, then drier soil is used, remove partial moisture, soil after drying, which enters in stirred tank, to be stirred, medicine machine is fixedly installed with above stirred tank, the medicine machine can launch corresponding stabilization agent in stirred tank according to relevant parameter, if the moisture content of soil is higher, quick lime can be launched in right amount, by the repairing effect of monitor real-time detection contaminated soil, if reparation reaches target value, soil after reparation can be transmitted to discharge port by crawler belt, area to be checked is transmitted to from discharge port by cleaning soil, if temporarily not up to repairing target value, then continue delivering medicament.The utility model solves the problems, such as that the prior art is relatively low to the treatment effeciency of heavy-metal contaminated soil, can save equipment cost, reduces operator, effectively prevent secondary pollution.
Description
Technical field
The utility model is used for environment protection field, handles the soil of heavy metal pollution, and in particular to an a kind of in-situ immobilization huge sum of money
Belong to the agitating device of contaminated soil solidification and stabilization.
Background technique
Barren rock mine tailings, to select smelting waste water, the heavy metal element in exhaust gas floating dust be all the primary pollution source of soil environment, is led to
Cross pollution irrigations, atmospheric falling dust etc. leads to content of beary metal increase in surrounding soil, thus make soil, surface water, underground water by
To pollution.
Amendement is that one or more substances are added into soil, and the physicochemical property by changing soil improves weight
The adsorption capacity of metal in the soil, or directly act on forming the small complex compound of solubility or precipitating with heavy metal, to drop
The migration of low-heavy metal in the soil, in favor of plant growth.But the microorganism remediation of existing heavy-metal contaminated soil
Technology has some limitations, such as micro- raw reparation duration length, slow effect, the danger for generally forming complex compound reduction heavy metal
Evil, can not remove heavy metal from soil.
Heavy-metal contaminated soil solidification recovery technique is by adding in different allogenic material (i.e. curing agent) fixing soils
Heavy metal element reaches a kind of important method for reducing heavy metals mobilization and biological effectiveness.Current main curing agent has
Cement, lime, flyash etc., their applicable surface is narrow, at high cost, and there are secondary pollutions, such as powder for some curing agent itself
Coal ash, the prolonged curing effect of curing agent are unstable etc..
Utility model content
Purpose of utility model: in order to solve the deficiencies in the prior art, the utility model provides an a kind of in-situ immobilization huge sum of money
Belong to the agitating device of contaminated soil solidification and stabilization.
Technical solution: a kind of agitating device of in-situ remediation soil polluted by heavy metals solidification and stabilization, including feed inlet, baking
Between dry machine, medicine machine, equipment operation, stirred tank, monitor and discharge port；
Contaminated soil after screening is placed in feed inlet, is transmitted by crawler belt, drier soil, removing unit are then used
Divide moisture, the soil after drying, which enters in stirred tank, to be stirred, and medicine machine is fixedly installed with above stirred tank, described
Medicine machine can launch corresponding stabilization agent in stirred tank according to relevant parameter, if the moisture content of soil is higher,
Quick lime can be launched in right amount, by the repairing effect of monitor real-time detection contaminated soil, reached target value if repairing, can will be repaired
Soil afterwards is transmitted to discharge port by crawler belt, is transmitted to area to be checked from discharge port by cleaning soil, if temporarily not up to repairing mesh
Scale value then continues delivering medicament.
As optimization: being connected between the medicine machine and equipment operation, staff sets dosing in equipment operation
The dispensing content of medicament in standby is operated.
As optimization: the medicine machine is equipped with several, is arranged in parallel between medicine machine.
The utility model has the advantages that the utility model solves, the prior art is relatively low to the treatment effeciency of heavy-metal contaminated soil to be asked
Topic can save equipment cost, reduce operator, effectively prevent secondary pollution.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
Embodiment
As shown in Figure 1, a kind of agitating device of in-situ remediation soil polluted by heavy metals solidification and stabilization, including feed inlet 1,
4, stirred tank 5, monitor 6 and discharge port 7 between dryer 2, medicine machine 3, equipment operation.

Partial moisture, the soil after drying, which enters in stirred tank 5, to be stirred, and the top of stirred tank 5 is fixedly installed with medicine machine 3,
The medicine machine 3 can launch corresponding stabilization agent in stirred tank 5 according to relevant parameter, if soil is aqueous
Rate is higher, can launch quick lime in right amount, by the repairing effect of 6 real-time detection contaminated soil of monitor, reaches target value if repairing,
Soil after reparation can be transmitted to discharge port 7 by crawler belt, be transmitted to area to be checked from discharge port 7 by cleaning soil, if temporarily not
Reach reparation target value, then continues delivering medicament.
In the present embodiment, the medicine machine 3 is connected between equipment operation 4, staff 4 between equipment operation in adding
The dispensing content of medicament in medicine equipment 3 is operated.The medicine machine 3 is equipped with several, between medicine machine 3 and townhouse
Column.
In the present embodiment, stabilization agent are as follows: medicament is added into soil and changes the existing forms of heavy metal in the soil,
It is set to be transformed into the substance of hypotoxicity, low-solubility and low migration, major technique includes redox potential technology, PH control
Technology processed, ion exchange technique, sedimentation, adsorption technology etc..Currently, common stabilization agent has sodium hydroxide, vulcanization
Sodium, phosphate, silicate, ferrous sulfate, iron oxide and macromolecule organic stabilizer etc..
The utility model solves the problems, such as that the prior art is relatively low to the treatment effeciency of heavy-metal contaminated soil, can save and set
Standby cost, reduces operator, effectively prevent secondary pollution.
The technical scheme in the utility model embodiment is clearly and completely described for above content, so that this field
