Although above-mentioned various anaerobic reactors have done many improvement, have it is very more the advantages of, exist it is following not
Foot：First, no external impetus, mixing and circulation mass transfer are not violent enough, and efficiency is not good enough；Second, internal part is more, not only structure
Complexity, also muddy water mixed solution can be circulated to form resistance, influence circulating effect.
Utility model content
The utility model is for deficiency existing for existing sewage treatment anaerobic reaction technology, there is provided it is a kind of it is simple in construction, into
The pulling flow type anaerobic reactor that this is low, treatment effeciency is high, easy to maintenance.
Pulling flow type anaerobic reactor of the present utility model, using following technical proposals：
The reactor, including housing, are divided into outer reaction zone, interior reaction zone and mud-water separating area in housing, in outer reaction zone
Top is gas collection treatment region, and sewage inlet pipe is provided with housing；Outer reaction zone connects with the bottom of mud-water separating area, outer reaction zone
It is interior at least to configure one at least provided with an interior reaction zone, the sealed bottom opened upper end of interior reaction zone, an interior reaction zone
Plug-flow pump, plug-flow pump are arranged at the periphery of housing, and the charging aperture of plug-flow pump is connected with suction tube, and suction tube stretches into outer reaction zone；
The discharge gate of plug-flow pump is connected with drainage conduit, and drainage conduit stretches into interior reaction zone.
The top of the outer reaction zone is arch, to be used as gas storehouse.
The top of the outer reaction zone is higher than the top of mud-water separating area and the top of interior reaction zone.
The top of the mud-water separating area is higher than the top of interior reaction zone.
The sewage inlet pipe is stretched into interior reaction zone, to avoid forming short stream with mud-water separating area.
The gas collection treatment region connects methane utilization device.
The suction tube also serves as discharge pipeline.
The suction tube is provided with equally distributed material sucking port in outer reaction zone bottom.
Sewage starts plug-flow pump after entering interior reaction zone, and by the effect of plug-flow pump and biogas air lift, muddy water mixed solution exists
Continuous circulation is formed between interior reaction zone and outer reaction zone, improves mixing efficiency and mass-transfer efficiency, sewage in a short time with
Microorganism high speed contact fast degradation.It is sufficiently mixed and mud-water separating area, precipitation filtering is entered by outer reaction zone with the sewage of mass transfer
After discharge.
The utility model is simple in construction, lifts circulation muddy water mixed solution using outside plug-flow pump, does not have lifting parts in housing
Part, violent and efficient continuance lifting, mixing and mass transfer under unobstructed state are realized, cycle-index is greatly speeded up, mass transfer
Efficiency is greatly improved, and treatment effect is greatly improved；Due to interior reaction zone and the high speed mass transfer of outer reaction zone, Yi Jini
Water Disengagement zone has significant mud-water separation effect so that has completely abolished three phase separator, this is in sewage treatment anaerobic field
It is subversiveness innovation；Simultaneously as plug-flow pump is arranged at hull outside, it is easily installed and safeguards.
