Description
Technical field
The invention belongs to organic solid castoff high-efficiency resource recycling field, specifically, relate to a kind of method of utilizing anaerobic digestion coupling pyrolysis technical finesse vinegar industry waste.
Background technology
Acid-sludge is a kind of foodstuff trade waste that produces in the vinegar brewing process.Because during Vinegar Production is the aerobic fermentation process, therefore can add during the fermentation the material of a large amount of rich cellulose, hemicellulose and pectin substance to guarantee the oxygen circulation of whole fermentation system.The utilization that is difficult to be decomposed in the vinegar brewing process of these added ingredientss is producing a large amount of acid-sludges in during Vinegar Production together with the major ingredient residues.China is that a vinegar is consumed big country, and annual consequent acid-sludge reaches 3,000,000 tons.The acidity of acid-sludge own is large (pH is 4 left and right), water ratio high (〉 70%) and decompose slowly, be the difficult point that urban environmental hygiene is administered.Current Domestic directly carries out landfill disposal with acid-sludge as rubbish always, but this processing mode can cause environment and groundwater pollution because of the sour water seepage.China had carried out research comparatively widely aspect the utilizing of acid-sludge in recent years, and using is to produce the modes such as feedstuff raw material, culture medium of edible fungus, cyclically utilizing or plant soil-less culturing matrix more widely.But generally speaking wherein crude fiber content is high as feed with acid-sludge, be of low nutritive value, and the cycle of fermentation is longer, treatment capacity is little, continuing to increase along with acid-sludge output in recent years, the method has appeared its drawback, the situation that the acid-sludge processing power can't be caught up with the acid-sludge generation must occur in the near future.
Anaerobic digestion techniques can be applied in the middle of the treating processes of acid-sludge as a kind of method that extensively is used in organic waste water and Castoff material energizing at present.Fermentation remaining ingredient and other organic constituents contained in acid-sludge can be converted into biogas under the effect of anerobe.But because the acidity of acid-sludge own is larger, anaerobic reactor easily causes the anaerobic System peracid that active generation of methanogen suppressed because charging acidity is excessive, reduce and process load and processing rate, be difficult to simultaneously keep the long-play of continuous anaerobic digestion reactor; Simultaneously acid-sludge this as a kind of residues, and acid-sludge is a kind of high lignocellulose material, anaerobic digestion process is mainly biogas with cellulose conversion wherein, remaining hemicellulose and lignin component are difficult to directly be utilized by anerobe.Therefore only processes by anaerobic digestion techniques that may to produce processing rate low and process the too much problem of natural pond slag afterwards.As introduce relevant preconditioning technique, and although can improve the anaerobic digestion gas production rate of acid-sludge itself, reduce intractability, can improve again processing costs and contain higher Na simultaneously
+Pre-treatment discharging of waste liquid problem.Although at present domestic have part vinegar factory to build acid-sludge direct combustion power generation system, the cost that generates electricity by way of merging two or more grid systems on the one hand is higher, and vinegar factory self scale is wanted high; Also caused simultaneously the pollution problem of atmospheric environment in energy recovery utilization and waste residue processing.Yet there are no, environmental protection efficient about acid-sludge, systematized treatment process.
