Description
Technical field
The present invention relates to field of waste water treatment and water-coal-slurry preparation field, specifically a kind of brewing wastewater is prepared the technique of water-coal-slurry.
Background technology
As everyone knows, light industry is quite serious to the pollution of water resource, wherein fermentation industry is only second to paper industry and occupies the second the pollution level of environment, and just shortage of China's water resource itself, the industrial pollution being on the rise has more caused the nervous situation of water resource today. In brewing wastewater, contain multiple accessory substance and discarded object that brewing process produces, the annual brewing wastewater producing of China is more than more than 4,000 ten thousand tons now, in waste water, COD is higher, the wastewater treatment expense of winery is greatly about 2 yuan/ton, disposal cost is higher, a lot of winerys are profit-seeking, waste water is not processed to direct discharge, not only waste resource, and cause serious industrial pollution, thereby fully and effectively brewing wastewater is fully utilized, both can alleviate environmental pollution, can save again the energy, reduce costs.
China is the country of a rich coal, oil-poor, weak breath, and coal has found that resource reaches 10141.02 hundred million tons, accounts for the more than 80% of fossil energy, petroleum resources relative shortage, and proved reserves are only 3 tons per capita, and are consumed in and increase rapidly. Water-coal-slurry is that coal is carried out to pulverizing and water and mixes containing surface-active dispersant solution, the pulpous state fluid being prepared from, then under carrying, power burns as heavy oil, the substitute products of heavy oil, residual oil, fallen by boiler combustion thereby reduce bulk petroleum, can save out bulk petroleum resource. Water-coal-slurry can improve the combustion rate of coal, reduces the pollution to environment, is the extremely promising Filter Tuber For Clean Coal fuel of one. The preparation technology of water-coal-slurry is quite ripe at present, mainly contains high concentration ore grinding pulping process, middle concentration ore grinding pulping process, height---middle concentration ore grinding associating pulping process. The coal resources of China's abundant, for water-coal-slurry preparation provides sufficient reliable coal on raw material is selected, various places are different different with quality requirement according to raw material, adopted suit measures to local conditions, diversified pulping process.
In brewing wastewater waste residue, existing moisture has again caloric value, be well suited for for the preparation of water-coal-slurry, can utilize its moisture can utilize again its available heating value, the harmless treatment of brewing wastewater waste residue can be fallen again simultaneously, kill two birds with one stone, the technique of utilizing at present brewing wastewater to prepare water-coal-slurry has no report.
Summary of the invention
For solving the technical problem of above-mentioned existence, the invention provides a kind of brewing wastewater and prepare the technique of water-coal-slurry, make full use of brewing wastewater and replace slurrying water, make full use of the heat in brewing wastewater waste residue, saving water resource again, realize the pollution-free processing of brewing wastewater, the pollution of the discharge of minimizing waste water and dregs to environment simultaneously.
For achieving the above object, the technical solution used in the present invention is as follows:
A kind of brewing wastewater is prepared coal water slurry process, realizes as follows:
