Abstract
The invention discloses a disposal method of thallium-containing solid waste, which comprises the following steps: mixing 0.3-0.5 part of polyacrylate emulsion, 0.3-0.5 part of ethylene-vinyl acetate copolymer emulsion and 1-2 parts of cement together by mass to prepare a thermosetting encapsulating material; and adding the thermosetting encapsulating material into the thallium-containing solid waste, mixing and stirring, and then maintaining, thereby finishing the disposal of the thallium-containing solid waste. The method not only reduces the consumption of the medicament and the capacity-increasing ratio, but also has good treatment effect, the leaching concentration of thallium pollutants in the waste residues after treatment is lower than the industrial wastewater thallium pollutant emission standard (DB 44/1989-2017), and the method can be popularized and applied in the field of thallium-containing solid waste treatment on a large scale.
Description
Technical field
The present invention relates to the technical field of solid waste disposal containing thallium, more particularly to a kind of disposal side of the solid waste containing thallium
Method.
Background technology
Hunan Province in 2014 issued national first industrial wastewater thallium pollution thing discharge standard-《Industrial wastewater thallium pollution
Thing discharge standard》(DB43/968-2014), Guangdong Province in 2017 have issued stricter《Industrial wastewater thallium pollution thing discharge mark
It is accurate》(DB44/1989-2017), these all propose requirements at the higher level to the safe disposal of the solid waste containing thallium.
In the prior art, newly-built waste water containing thallium treatment technology is mainly vulcanization method+absorption method handling process, but the party
Method has largely containing thallium vulcanization waste residue generation, and using technologies such as the lime stabilization of routine and cement solidifications, there is dosing
The problems such as height, disposal effect difference.
The content of the invention
In order to solve the technical problems such as high, the disposal effect difference of the dosing in the existing technology of solid waste disposal containing thallium,
The invention provides a kind of method of disposal of solid waste containing thallium, reagent consumption amount is not only reduced, reduces increase-volume ratio, and
With good disposal effect, the leaching concentration of thallium pollution thing is less than in waste residue after disposal《Industrial wastewater thallium pollution thing discharge mark
It is accurate》(DB44/1989-2017), can be in the large-scale promotion application in the field of solid waste treatment containing thallium.
The purpose of the present invention is achieved through the following technical solutions：
A kind of method of disposal of solid waste containing thallium, comprises the following steps：
Step A, according to mass parts meter, by 0.3~0.5 part of polyacrylate dispersion, 0.3~0.5 part of ethene-vinyl acetate
Ester copolymer emulsion, 1~2 part of cement mixing together, so as to which thermosetting cover material be made；
Step B, the thermosetting cover material is added in solid waste containing thallium and mixed, then conserved,
So as to complete the disposal of the solid waste containing thallium.
Preferably, the mass ratio of the thermosetting cover material and the solid waste containing thallium dried is 0.1~0.2:1.
Preferably, the curing time of the maintenance is 24~48 hours.
As seen from the above technical solution provided by the invention, the method for disposal of the solid waste provided by the invention containing thallium
The solidification of thermosetting cover material is taken full advantage of, thermosetting cover material and the solid waste containing thallium of naturally dry are mixed
Stirring is closed, so as to not only increase the safe disposal efficiency of the solid waste containing thallium, is improved at the stabilisation of the solid waste containing thallium
Effect is put, and reduces reagent consumption amount, reduces increase-volume ratio, is less than the leaching concentration of thallium pollution thing in waste residue after disposal
《Industrial wastewater thallium pollution thing discharge standard》(DB44/1989-2017), therefore may be implemented in the field of solid waste treatment containing thallium
Large-scale promotion application.
Embodiment
The technical scheme in the present invention is clearly and completely described below, it is clear that described embodiment is only
Part of the embodiment of the present invention, rather than whole embodiments.Based on embodiments of the invention, those of ordinary skill in the art exist
The every other embodiment obtained under the premise of creative work is not made, belongs to protection scope of the present invention.
The method of disposal of the solid waste provided by the present invention containing thallium is described in detail below.In the embodiment of the present invention
The content not being described in detail belongs to prior art known to professional and technical personnel in the field.
A kind of method of disposal of solid waste containing thallium, comprises the following steps：
Step A, according to mass parts meter, by 0.3~0.5 part of polyacrylate dispersion, 0.3~0.5 part of ethene-vinyl acetate
Ester copolymer emulsion, 1~2 part of cement mixing together, so as to which thermosetting cover material be made.
Step B, the thermosetting cover material is added in the solid waste containing thallium of naturally dry and mixed,
The mass ratio of the thermosetting cover material and the solid waste containing thallium of naturally dry is 0.1~0.2:1, then to carry out 24~48 small
When maintenance, so as to i.e. complete the solid waste containing thallium disposal, the waste residue after being stabilized.
Specifically, the thermosetting cover material obtained by step A of the invention after solid waste mix with that can form resin
Concrete, not only intensity is high and corrosion-resistant, height is impervious, frost resistance is good for this resin concrete, is very suitable for solid containing thallium and gives up
The disposal of thing.The solidification that the method for disposal of the solid waste provided by the present invention containing thallium takes full advantage of thermosetting cover material is made
With thermosetting cover material and the solid waste containing thallium of naturally dry being mixed, so as to improve the solid waste containing thallium
Safe disposal efficiency, improves the stabilization treatment effect of the solid waste containing thallium, and reduces reagent consumption amount, reduces increasing
Hold ratio, the leaching concentration of thallium pollution thing is less than in waste residue after disposal《Industrial wastewater thallium pollution thing discharge standard》(DB44/1989—
2017) it, may be implemented in the large-scale promotion application in the field of solid waste treatment containing thallium.
As fully visible, the embodiment of the present invention not only reduces reagent consumption amount, reduces increase-volume ratio, and have well
Effect is disposed, the leaching concentration of thallium pollution thing is less than in waste residue after disposal《Industrial wastewater thallium pollution thing discharge standard》(DB44/
1989-2017), can be in the large-scale promotion application in the field of solid waste treatment containing thallium.
The foregoing is only a preferred embodiment of the present invention, but protection scope of the present invention be not limited thereto,
