In the hydrolysis acidification stage, the methane phase stage of my biogas is converted by methane backeria with volatile fatty acid.Hydrolysis Acidification is very fast
Speed, and methanogenic phase is to slow.
Good mixing is the basis that anaerobic reactor is capable of stable operation, and on the one hand mixing can make microorganism and substrate
Fully contact and improve reaction rate；On the other hand, the alkalescence that the acidic materials that acidifying bacterium produces can be produced by methane backeria in time
Material is neutralized, it is to avoid local acidifying suppresses methane backeria activity.
Efficient anaerobic reactor is generally tank structure, such as UASB, EGSB, and reason is the anaerobic reaction of tank structure
Device, the depth of water is higher, 10-20 meters of even more highs, and the biogas that reactor lower part is produced can produce disturbance in uphill process, add
Outer circulation backflow increase upflow velocity, results in good mixed effect, and without dead angle.
Acidifying is a big problem of anaerobic reactor stable operation, such as baffling type anaerobic reactor, in this reactor
In, because the barrier of baffle plate makes sewage vertical folding stream pass through sludge blanket.In actual motion, feed loading all concentrates on first
In cell, first serious overload operation in cell is caused, causes zymotic fluid to be acidified, is suppressed the activity of methanogen,
Feed liquid flows in plug flow type, and acidated first Room feed liquid can release the sludge of each room below and be allowed to be acidified.In order to overcome
Acidifying, by the way of returned sludge that methane backeria feeding first is indoor, because the first Room is constantly fed, backflow, which does not have, prevents acid
The effect of change.Concrete sump reactor according, based on construction cost, the general depth of water there was only 5-6 meters but area is larger.Itself aerogenesis band
The mixed effect come is limited, and in order to stable, efficient operation, the requirement to water distribution, mixing is higher.The utility model is therefore
.
