Description
Technical field
The invention belongs to Solid Waste Treatment, disposal and application technology as the second resource field, more particularly to a kind of dyeing and printing sewage
The production method for the treatment of plant's firing sludge clinker bricks in environmental protection.
Background technology
Textile industry is one of important national industry in China, in modern economy globalization and the condition of New Sci-and Tech-Revolution
Under, China is going into the period for becoming weaving power by the big country that weaves.Waste water caused by dyeing, accounts for industrial wastewater
The 1/10 of total release.According to incompletely statistics, China there are about 7.2x10 every year8m3Dyeing waste water is discharged into water environment, is current most main
One of pollution source of water body wanted.At present, the processing method of dyeing waste water is still generally based on bioanalysis, Biochemical method effect
Preferably, but can produce substantial amounts of excess sludge simultaneously, produce sludge quantity account for handling water 0.5% or so (using moisture content as
97% meter)；In sewage treatment plant, handle sludge expense account for run total cost 20%-50% be even as high as 70% so that spin
Knitting printing and dyeing enterprise needs to put into excessive fund in this respect, but not necessarily obtains preferable treatment effect, and this has become system
An about big key factor of textile industry development.
At present, China is in the period of Process of Urbanization Construction high speed development, and land resource, the energy are all very in short supply, therefore
Making construction material using municipal sludge has vast potential for future development.Not only may be used using sludge as raw material in high-temperature roasting product
So that sludge is realized innoxious, secondary pollution is prevented, and contained organic matter has certain caloric value in sludge, can supplement high temperature
Heat needed for roasting, while unnecessary energy resource consumption is decreased, both it has been beneficial to develop itself benignly circulated economics, discarded object
The recycling and industrialized requirement of processing, while also comply with and forbid ruining field shoveling brickmaking, the principle of cultivated land resource is saved, was both met
The demands of a large amount of construction sintered articles, the state basic policy for the sustainable development for reducing resource consumption that reduces environmental pollution is realized again
Draw and Circular Economy.
