A kind of UASB anaerobic reactors
Technical field
The utility model belongs to technical field of sewage treatment equipment, and in particular to a kind of UASB anaerobic reactors.
Background technology
UASB reactors waste water is uniformly introduced the bottom of reactor as far as possible, and sewage is upwardly through including granule sludge
Or the Sludge Bed of floc sludge.The process contacted in waste water and mud granule occurs for anaerobic reaction.Produced under anaerobic state
Biogas (mainly methane and carbon dioxide) causes the circulation of inside, and this is favourable for the formation and maintenance of granule sludge.
Some gases of sludge blanket formation are attached on mud granule, and attachment and the gas without attachment rise to reactor head.On
The sludge for being raised to surface hits the bottom of phase reactor gas launcher, causes the sludge flco of bubbles attached to deaerate.Bubble
Mud granule will be deposited to the surface of Sludge Bed after release, and attachment and the gas without attachment are collected into the three of reactor head
The collection chamber of phase separator.The acting as of the baffle plate being placed under collection chamber unit interstices and prevents biogas bubble at gas launcher
Into settling zone, otherwise the wadding for causing settling zone is moved, particle can be hindered to precipitate.Comprising some remaining solids and mud granule
Liquid enters settling zone by separator gap.
Because the area of passage of the skew wall settling zone of separator increases when close to the water surface, therefore upflow velocity is in close row
Put a reduction.Because flow velocity reduction sludge flco can flocculate and precipitate in settling zone.Accumulate the sludge on three phase separator
The frictional force that flco will be maintained on skew wall more than it to a certain extent, it will slide back to reaction zone, and this partial sludge again will be with
Entering organic matter of water reacts.
