Abstract
The invention provides a method for producing building materials by using white mud aiming at the problem of the prior art that white mud, acid water, silicon sludge and the like in industrial wastes can not be recycled. The method comprises the steps: the white mud, the acid water, the silicon sludge and the like, are mixed according to a certain matching ratio, uniformly stirred, and then stands for precipitating, and the upper water is discharged and the chlorine content of the obtained mixture after pressure filtering is less than 1 percent. The method can be used for producing gypsums and bricks and paving building materials, etc. The method of removes the biggest hidden trouble of enterprise development, reduces environment pollution and saves large quantities of building materials, thus causing soda and silica industry to be on the track of sustainable economic development.
Description
Technical field
The invention belongs to field of inorganic chemical engineering, is the method for industrial refuse being handled recycling, specifically utilizes white clay to produce the method for material of construction.
Background technology
White clay is to produce the industrial refuse that is discharged in the soda ash process with integrated process, is paste, contains lime carbonate, calcium oxide, calcium chloride, calcium sulfate and some other impurity.Since the muriate separation difficulty, thereby be taken as garbage emission basically entirely, though all departments draw attention to this, to attempt, as utilize white clay to remove sulfurous gas and making sterilant its improvement, consumption is very little, thereby can not get basic improvement.An enterprise that produces 600000 tons of soda ash per year produces white clay also near 600,000 tons, and the most of white clay that makes can only be regarded garbage emission, and this not only pollutes environment, also is a kind of waste of resource simultaneously.
Silicon mud is meant a kind of industrial refuse that discharges in the silica gel production process, main component is a silicon-dioxide, can't utilize again because of containing compounds such as excessive iron, aluminium, sodium, an enterprise that produces 30000 tons in silica gel per year, year discharging silicon mud surpasses 10,000 tons, does not also have the treatment process of science, the also method processing by burying and stacking for silicon mud, not only cause the waste on the energy, also cause great pollution.
To be silica gel enterprise add in producing washing silica gel process sour water that quantitative sulfuric acid washes out sodium oxide contained in the silica gel and the waste water produced, and the pH value is at 1-1.6.An enterprise that produces 30000 tons of silica gel per year, 4000 cubes of daily output sour waters, the sour water of discharge need neutralize and could discharge, and the handling number is huge.
Thereby, how effectively to handle and utilize above-mentioned industrial refuse, a problem that then becomes the present invention and faced.
Summary of the invention
