Figure.As shown in Figure 1, embodiments of the present invention provide a kind of anaerobic reactor for sewage disposal, the anaerobic reactor
Including tank body 1, the sewage water inlet pipe 2 that is set to 1 side of tank body, be set to tank body 1 bottom aeration pipe network 3 and be located at tank
Biogas pooling zone 4 at the top of body, the interior anaerobic activated sludge having for the organic pollution in sewage of degrading of tank body 1, biogas
Pooling zone 4 is connected to by biogas return duct 5 with aeration pipe network 3.When the anaerobic reactor runs work, sewage is from wastewater influent
Pipe 2 enters in the tank body of the anaerobic reactor, and the anaerobic activated sludge organic contamination public criticism in sewage that can degrade reaches purification
Effect.Most organic matter can be converted into biogas in sewage, and biogas rises effusion from sewage and is gathered in biogas and collects
Area 4.Biogas in biogas pooling zone 4 can enter the aeration pipe network 3 for the bottom for being set to tank body 1 by biogas return duct 5, from
And the inside of tank body 1 is flowed back into carry out aeration agitation to sewage, reach the mass transfer condition enhanced inside the anaerobic reactor, carries
Rise the effect of sewage treating efficiency.
Mass transfer condition based on the anaerobic reactor inside enhancing, under the effect of lifting sewage treatment effeciency, the anaerobism
Reactor can be designed more short, in order to be kept the temperature and installed in cold area, make the suitable of the anaerobic reactor
It is greatly promoted with property.When the anaerobic reactor is designed more short, for the volume of 1 treated sewage of tank body, then the anaerobism
The floor space of the tank body 1 of reactor is correspondingly designed larger, while biogas return duct 5 may be designed in larger diameter,
To improve the flow of the biogas of reflux, internal mass transfer effect is further increased.
As shown in Figure 1, the anaerobic reactor further includes the separation cover 6 being set in tank body 1, separating cover 6 can be by tank body 1
