Abstract
The present invention relates to detoxifcation utilization of barium slag and chromium slag, and belongs to the environmental protection treatment field of wastewater, waste slag and waste gas. The present invention is characterized in that 10% to 90% of barium slag and 10% to 90% of chromium slag according to the harmful matter contents of barium slag and chromium slag are mixed and detoxicated by adding water, and detoxicated slag is used as mineralizing agents for cement production, coloring agents in glass and ceramic industry and collecting materials for road engineering. The present invention can well simultaneously treat two kinds of poisonous waste slag in low cost, and the detoxicated slag after treatment can be used as raw materials for other industrial production, and have certain values. The ultimate utilization and the treatment of the detoxicated slag are safe and reliable, which can create good environmental benefit and economic benefit.
Description
The invention belongs to environment protection disposal of waste gas, water and industrial residue field.
Barium slag, two kinds of industrial residues of chromium slag system, the barium slag and the chromium slag of the annual discharging of China reach more than the few hundred thousand tonnes of, and its contained water-soluble barium or water soluble chromium all are radioactive substance.How this two kinds of waste residues are made good use of in improvement, and reducing its pollution to environment is an important topic of efforts at environmental protection.
For solving the pollution of barium slag, chromium slag, domestic existing multiple technologies scheme is administered respectively them.Administer the technology of two kinds of waste residues simultaneously, promptly utilize the technology of barium slag, the brickmaking of chromium slag that report was arranged, but because barium chromium slag brick when meeting heat or meeting acid, will discharge H
2The s obnoxious flavour so its application is limited to, fails to promote.
The purpose of this invention is to provide a kind of less investment, eat that the quantity of slag is big, treatment cost is low, simultaneously the way of two kinds of harmful slags of processing and utilizing.
Main points of the present invention are stated as follows:
Because the state of the art difference of each discharging factory, the main harmful toxic matter of barium chromium slag, the content of water-soluble barium or water-soluble 6 valency chromium can differ more than 10 times, so the proportional quantity of two kinds of slags that adopt changes greatly, its scope is: the barium slag: chromium slag=10%-90%: 10%-90%.
Choose after the proportional quantity according to the content of water-soluble thing, two kinds of slags are added water mix and stir reaction, reexamine the aqueous solution color and luster that mixes and stirs slag, if solution presents dark color, as yellow, green-yellow illustrates that then barium slag material is not enough, should add the barium slag up to not presenting dark color, if mixing slag solution presents turbid white, but chromatize slag then, up to mixing and stirring the slag water white transparency, promptly reach the detoxifcation purpose of two kinds of slags.
For making the ultimate disposal of detoxifcation slag good, the detoxifcation slag can be applied in the following purposes:
1, manufacture of cement, as the mineralizer that cement slurry burns till, the retardant of grog and Additive etc.
2, because detoxifcation slag system strong basicity material, can be with its neutralizing agent as acid material, mix the detoxifcation slag as phosphogypsum, fluorgypsum, citric acid gypsum after, can adjust their pH value, be beneficial to the application of these materials.
3, the detoxifcation slag can be made toner usefulness in glass, the Production of Ceramics, because its composition contains Ba, Cr equal solvent and the ion of showing signs of anger, it is safer to make toner than existing chromium slag during use, and cost is lower.
4, detoxifcation slag system active alkali material can be used as and uses as the ore powder that gathers materials that replaces the asphalt pavement construction gathering materials of road engineering.Also can be mixed with the concrete goods that alkaline agglutinate supplies to make road concrete goods or makes other.
Existing barium slag, treatment of chromate slag scheme utilize the quantity of slag limited, the detoxifcation after end-use extensively do not limited applying of they, this programme less investment, running cost be low, handle that the quantity of slag is big, the slag purposes after the detoxifcation is wide, price is low, can obtain user's welcome, ultimate disposal utilizes safe and reliable, implements can produce environmental benefit and economic benefit preferably behind this programme.
Embodiment 1
Barium slag (water-soluble barium content 3.5%) chromium slag (water-soluble 6 valency chromium content 0.16%)
Barium slag: chromium slag=35: 65
Add water and mix and stir the detection slag specimen aqueous solution: water white transparency
Oven dry detoxifcation slag is milled to 200 orders, and in 6% adding frit, frit can no longer add the barite powder, and it is emerald green that glass is, the more water-soluble 6 valency chromium＜0.5ppm of check sample
Embodiment 2
Barium slag (water-soluble barium content 2.5%) chromium slag (water-soluble 6 valency chromium content 0.3%)
Barium slag: chromium slag=70: 30
Add water and mix and stir the detection slag specimen aqueous solution: water white transparency
With the detoxifcation slag with 5% weight add cement slurry through grinding, burn till, to detect physicochemical data by national cement standard behind the grinding qualified, water-soluble 6 valency chromium＜0.5ppm of check sample again.
Claims (1)
1, a kind of purposes of detoxifcation slag of barium and chromium slag, its special seized with terror be the scope of determining their proportional quantity according to the content of the water-soluble toxic substance of barium slag and chromium slag, the barium slag is 10%-90%, and the chromium slag is 10%-90%, and barium slag that proportioning is good and chromium slag add water and mix and stir, detect the color and luster of the slag specimen aqueous solution again, and adjust the quantity of slag of proportioning, color and luster deeply then adds the barium slag, the turbid chromatize slag then in vain of color and luster, solution water white transparency up to getting slag specimen gets final product, and the purposes of detoxifcation slag is as follows:
(1) be used for manufacture of cement: as the mineralizer that cement slurry burns till, the retardant of cement clinker or Additive;
(2) make the neutralizing agent of acid material, in phosphogypsum, fluorgypsum, citric acid gypsum, mix this detoxifcation slag, can adjust their pH value, facilitate the use;
(3) owing to contain Ba, Cr ion in the detoxifcation slag composition, tool flux and do the toner effect, this slag can be used as the production that the raw material of showing signs of anger is used for pottery or glass;
(4) gather materials as road engineering, replace the gathering materials of asphalt pavement construction raw material, ore powder;
(5) the active alkaline material of this detoxifcation slag system tool, it can be mixed with alkaline agglutinate.
