Description
Technical field
The utility model relates to a kind of sewage disposal device, particularly a kind of efficient hybrid anaerobic reactor.
Background technology
UASB (Up-flow Anaerobic Sludge Blanket), i.e. flow lifting type anaerobic sludge reaction bed, this treatment process obtained in the processing at high-concentration organic industrial waste water using widely the beginning of the eighties in last century.
UASB is made up of sludge reaction district, gas-liquid-solid three-phase separator (comprising the settling region) and air chamber three parts.In the reaction zone of bottom, retain a large amount of anaerobic sludges, the mud with good sedimentation function and cohesion performance forms sludge blanket in the bottom.The sewage of handling from anaerobic mud bed bottom flow into sludge blanket mud mix and contact, the organism in the microbiological degradation sewage in the mud is converted into biogas.Biogas is constantly emitted with the micro-bubble form, and micro-bubble constantly merges in uphill process; Form bigger bubble gradually, on Sludge Bed top because the stirring of biogas forms the thinner mud of sludge concentration and the water entering triphase separator that rises together, when biogas is run into the reflector of separator bottom; Be folded to reflector around, pass water layer then and get into air chamber, concentrate on the biogas of air chamber; Derive with conduit, the solid-liquid mixed solution is through the settling region of reflection entering triphase separator, and the mud in the sewage flocculates; Particle increases gradually, and sedimentation under action of gravity.The mud that is precipitated on the skew wall is slided back in the anaerobic reaction district along skew wall, makes a large amount of mud of accumulation in the reaction zone, overflows on overflow weir top from the settling region with the treat effluent after mud separates, and discharges Sludge Bed then.
Traditional U ASB reactor drum has like following shortcoming:
1, the mud in the UASB reactor drum generally has two kinds of forms to exist, i.e. floc sludge and granule sludge.Floc sludge is prone to the current come-up, causes the organism in the reactor drum to be flowed out easily, so the formation of granule sludge is most important to the stable and operating safety of whole UASB reactor drum.The culture cycle of the active particle mud of tradition UASB reactor drum is very long; Do not have the inoculation granule sludge, generally need 6 months to 1 year, in addition more of a specified duration; Just can turn out the sludge quantity that satisfies design loading, this also is UASB technology very big bottleneck in engineering practice.
2, the homogeneity question of water distribution.The bottom water distribution system of UASB reactor drum can be most important with mixing of reactor bottom mud for water inlet, makes the muddy water thorough mixing, is UASB reactor drum problem demanding prompt solution.
3, the control problem of pH value in the reactor drum.The methanogen that produces methane phase in the anaerobic stages is single-minded anaerobic bacterium, the pH narrow range that this bacterium is suitable, and optimal ph is 6.5～7.7, and the variation of pH value can cause methane-producing bacteria to be suppressed, and effluent quality worsens, and destroys the entire treatment system.
