Background technology
Organic substance is under anaerobic decomposed by anerobe and produces the process of methane and carbon dioxide, because oxygen shifts out from organism under the condition of air deficiency and generates CO2's.No matter be acid fermentation, or biogas fermentation, the oxygen participating in biochemical reaction is all the nitrite coming from water, organism, nitrate or be decomposed.
The biochemical stage of anaerobic digestion was mainly divided into the next stage:
Ith stage hydrolysis produces acid phase:
Insoluble larger molecular organics in sewage, as polysaccharide, starch, Mierocrystalline cellulose, hydro carbons (alkane, alkene, alkynes etc.) hydrolysis, primary product be first, second, third, butyric acid, lactic acid; And then amino acid, protein, fat splitting generate ammonia and amine, polypeptide etc. (so some books produce acid hydrolysis be again divided into two stages).
IIth stage Anaerobic fermentation gas stage:
These small organic molecules, under the effect of methanogen, are converted into methane by the fermenting process of methanobacteria by the small organic molecules such as the Ith stage product formic acid, acetic acid, methylamine, methyl alcohol.So not very big in COD, BOD value change of acidication stage, the organism only in the aerogenesis stage due to formation COD or BOD is overflowed mainly with the form of CO2 and H2, just makes COD, BOD in waste water obviously decline.
At souring stage, hydrolysis of organic matter is converted into the 1st micromolecular organism that directly can be utilized by methanobacteria by fermenting bacteria, as acetic acid, formic acid, methyl alcohol and methylamine etc.; 2nd class is the organism that directly can not be utilized by methanobacteria, and as propionic acid, butyric acid, lactic acid, ethanol etc., incomplete anaerobic digestion or fermentation leave it at that.If continue full anaerobic process, then produce hydrogen, the 2nd type organic is further converted to hydrogen and acetic acid by acetogen.
IIIth methane phase stage in stage:
Methane-producing bacteria is converted into methane matrix such as formic acid, acetic acid, methylamine, methyl alcohol by different approaches, and wherein topmost matrix is acetic acid.
