Industrial residue, increases 40,000,000 tons of industrial phosphogypsum newly every year, and storage phosphogypsum slag is up to 300,000,000 tons at present, environment is caused greatly
Pollution, and phosphogypsum slag is only small part in Industrial Solid Waste, the accumulation of the substantial amounts of Industrial Solid Waste in the whole nation, to the ring in the whole nation
Border contamination hazard causes state leader department to pay much attention to, and successively puts into effect the comprehensive utilization of multinomial policy supporting industry solid waste energetically
Processing.
The target of solid waste processing is innoxious, minimizing, recycling.With China to environmental protection into one
Step is paid attention to, and fixed offal treatment has very big increment space.The whole nation Industrial Solid Waste yield at 32.56 hundred million tons, and
Industrial Solid Waste comprehensive utilization ratio is no more than 40%, is still had greater room for improvement.Government inherently opens up energetically in China
Fixed-end forces business is opened, this is also measure extremely urgent under present circumstances, is consolidated especially for sulphur gypsum, ardealite
Useless processing, it is domestic at present it may be said that completely without breakthrough progress.
Sulphur gypsum and phosphogypsum slag are mainly used for making cement retarder and make building-block, plate and building sand
Slurry, both the above waste residue be Sichuan in the main place of production in China, the ground such as Yunnan and Guangxi, its amount produced mistake MT ranks, largely
Heap soil of being rivals in a contest generate serious pollution.
Therefore, it is necessary to propose a kind of sulphur gypsum and phosphogypsum slag brickmaking technology for the above problem.
The content of the invention
