Technical field
The invention belongs to environmental technology fields, and in particular to a kind of stable curing processing method of mercurous waste material.
Background technology
Now, domestic industry interface is faced various industry have generated and various waste materials that are generating and may just be produced
Come or produced and heap is abandoned in some pit-holes or underground, and may polluted underground water, rivers and creeks water or Lake Water, cause to give birth to
Object urgency toxicity or chronic toxicity finally enter due to biological chain, accumulate on human body, cause the murder by poisoning of human body and cause a disease or suffer from cancer.
National environmental protection mechanism has promulgated regulations, after waste material containing heavy metal Hg or waste liquid can be stabilized or cured, by leaching
After experiment reaches certain standard, it can further be recycled or burial is handled.
It is at present to mix to cure with various cementitious materials with waste material to the method for waste disposal, shortcoming is that include cannot
Fully cure liquid waste or body refuse type waste material or related cementitious material does not show notable hardening effect.Such as single make
Cure waste material with waterglass or portland cement, formed a kind of high osmosis, it is porous, easily leach and mechanical strength it is not high
Solid product or because the coherency deficiency of conjugate or chemical dissociation constant are excessively high so that leaching test process generates
The phenomenon dissolved out again, and fail to reach recycling or the stringent leaching test standard of burial.
The content of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of stable curing method of mercurous waste material, gained cures production
The volume of object is less than with the volume and cured product of final product obtained by prior art curing process be solid, curing degree of mercury reaches
More than 90%.
The stable curing reason method of the mercurous waste material of the present invention, includes the following steps：
It is 6~9 to grind and adjust pH value mercurous waste material, adds in cementitious material and is uniformly mixed to form mixed slurry, controls
The mass fraction of free fluid is in 20wt%~50wt% in mixed slurry, sequentially added into mixed slurry sulfide solution,
Polyacrylamide solution reaction obtains reactant, and reactant is placed in mold, up to cured product when curing 10~20 is small；Institute
The addition for stating polyacrylamide solution is 1wt%~3wt% of mercurous waste material quality.
In the present invention, the mercurous waste material be mercurous solid waste or mercurous liquid waste, the mercurous liquid material
In contain free fluid, thus free fluid or external adding water of the free fluid in mixed slurry in mercurous waste material, it is described
Free fluid refers to the attached liquid for being stored in solid not in the form of the crystallization water.
Preferably, the adjusting pH value is 7~8.
Preferably, the mass fraction of free fluid is 20wt%~50wt% in the mixed slurry.
In the present invention, for increase waste material in contained solid particle surface area and reduce the solid material ruler in waste material
It is very little, mercurous waste material need to be ground, make waste granules grain size≤10mm.
Preferably, the cementitious material is slag-portland cement.
Preferably, the addition of the cementitious material is 10wt%~90wt% of mercurous waste material quality.
As it is further preferred that the addition of the cementitious material is divided into following 2 kinds of quantitative manners：Mercurous waste material be containing
During mercury solid waste, the addition of cementitious material is 10wt%~30wt% of mercurous waste material quality；
When mercurous waste material is mercurous liquid waste, the addition of cementitious material is free liquid weight in mercurous waste material
70%~90%.
Preferably, the addition of the chemical bond is 2wt%~5wt% of mercurous waste material quality.
Preferably, the one kind of the vulcanization salting liquid in sodium sulfide solution, potassium sulfide solution.As further excellent
Choosing, the vulcanization salting liquid is sodium sulfide solution.
Preferably, the mass fraction of vulcanized sodium is 10wt%~20wt% in the sodium sulfide solution.
Preferably, the addition of the flocculating agent is the 2wt% of mercurous waste material quality.
Preferably, the mass fraction of polyacrylamide is 0.01wt%~0.03wt% in the polyacrylamide solution.
In the present invention, the mercurous waste material of processing, the nuke rubbish including chemical waste and low, middle amount, aromatics heavy oil and coke
Oil, creasote, sludge tar, slot bottom；Black petroleum products, tar and the dregs of fat；Petrochemistry heavy oil and tar and institute's by-product with
And the tank slag containing polymer；Halogenated organic detritus containing Polychlorinated biphenyls, dioxin and other chlorinated solvents for forming slot bottom；Containing arsenic
Pesticide/herbicide residue；Organic and inorganic sludge and the waste material containing mercurous slot bottom rubbish；Inorganic residues, plating and metal

Dirt；It is absorbed or is trapped in solid granulates or absorbs the exhaust gas in liquid and incinerate ashes.
The processing method of the present invention also has effective solidification effect to other heavy metals.
Advantageous effect：
In method provided by the invention, sulfide solution, cementitious material and waste material are crosslinked and are bonded by solidification process,
This solidification process changes the physics and chemical property of waste material.The process reduces the infiltration coefficient of waste material and matrix of waste modeling
Sex index, and increase in it in mechanical strength, the carrier for bearing weight is made when curing.This method provide one kind makes
The part microencapsulation that is wrapped by and closes that chemical reaction combines is had neither part nor lot in matrix, so as to which the part that is closed is by gelling material
It microencapsulation and is actually become impervious and substantially without exudation in the gap that material particle is formed.Reaction between each component
It is fully happened on whole particle surfaces of waste material.The active effect in this course of some waste materials, initiatively rising
The effect of reactant is learned, to physical hardening and permeability is reduced and exudative makes further contribution.The final waste products of gained
Volume be less than the volume used and state final product obtained by prior art curing process.
In addition the present invention is additionally added polyacrylamide solution, can improve mixed slurry viscosity, prevent cementitious material
Instantaneous curing, by slowing down solidification process, change conjugate viscosity, finally effectively increase solidfied material compact substance, further
The possibility for reducing cured product and oozing out again.
In the prior art at present, it is generally not high for the curing degree of the mercurous waste material of low leach concentration, and at the present invention
Reason method is simple, of low cost, to the curing degree of the mercurous waste material of low leach concentration up to more than 90%, it might even be possible to reach
100%.
