Abstract
The utility model relates to an active sludge separation device, which is characterized in that the activated sludge separation device comprises a sludge collection pond, two water inlet pipes, a sludge return pipe and a sludge return pump, wherein the water outlet end of each water inlet pipe is provided with an elbow, a water outlet is perpendicular to a vertical pipe body of each water inlet pipe, the water outlet is just against the vertical inner wall of the sludge collection pond, the sludge return pipe is communicated with the bottom of the sludge collection pond, and the sludge return pipe is connected with the sludge return pump. The active sludge separation device disclosed by the utility model has the beneficial effects that a situation that precipitated sludge is impacted upwards in the process of feeding water can be prevented, the sludge-water separation effect is good, the sludge precipitation speed is rapid, and the collecting efficiency is high.
Description
Technical field
The utility model relates to the technical field that adopts biotechnology to dispose of sewage, particularly a kind of activated sludge separator.
Background technology
Using in wastewater treatment at present is A/O technique more widely.The A/O biological treatment is comprised of anaerobic and aerobic two parts.After sewage enters anaerobic pond, under the condition of anaerobic, utilizing the anaerobe effect, is mainly to utilize anaerobic bacteria to process organic matter in waste water.
Sewage enters Aerobic Pond after processing through anaerobe, makes good use of the polluter in the metabolism oxidation Decomposition waste water of oxygen animalcule self.It is that aerobic microbiological and aerobic-anaerobic microbe participate in that aerobe is processed, having under the condition of dissolved oxygen, and be CO with organic substance decomposing
2And H
2O, and the metabolic process that gives off energy.The hydrogen of deviating from the oxidation operation process be with oxygen as hydrogen acceptor, organic decomposition is more thorough, end product is the minimum CO of energy content
2And H
2O, therefore it is many to release energy, accretion rate is fast, metabolite is stable.
No matter be the anaerobic reation pool of anaerobic stages, or the aerobic reaction pond of aerobic stage, all need the part mud that refluxes, ensure the quantity of the active microorganism in reaction tank.Existing mud retracting device is generally sedimentation basin, mostly adopts the square water mud sump, and water inlet pipe is placed in the upper end open of sedimentation basin, directly sewage is squeezed in the pond by intake pump, the Aerobic Pond of by pipeline sending front after mud precipitates in sedimentation basin.The sludge recovery system of this structure need to be squeezed into sedimentation basin with mud with water pump, and power consumption is large, and easily the mud that precipitates has been rushed again in the water inlet process, and the sludge settling time is long, and sedimentation effect is bad, the collection of inconvenient precipitating sludge and backflow.
Summary of the invention
The technical problems to be solved in the utility model is: provide a kind of can preventing to rush precipitating sludge in the water process, mud-water separation is effective, the activated sludge separator that sludge settling speed is fast, collection efficiency is high.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of activated sludge separator, it is characterized in that: comprise mud collecting pit, two water inlet pipes, mud return line and sludge reflux pumps, the water side of described water inlet pipe is provided with elbow, delivery port is vertical with the vertical body of water inlet pipe, delivery port is over against the vertical inner wall of mud collecting pit, and mud return line is communicated with bottom the mud collecting pit, and mud return line connects sludge reflux pump.
The delivery port of described water inlet pipe is positioned in the middle part of the mud collecting pit, the inwall at mud collecting pit middle part is provided with current buffering net, the plane of this current buffering net becomes 30 ° of angles with the inwall at mud collecting pit middle part, the plane of current buffering net is towards mud collecting pit bottom, can slow down flow rate of water flow, reduce water flow dynamic energy, prevent that precipitating sludge from having been rushed.
Described mud collecting pit bottom is taper, and taper surface is 60 ° with mud collecting pit bottom surface angle, facilitates sludge settling and quick collection, raising mud gathering speed and backflow efficient.
The beneficial effects of the utility model are: can prevent from having rushed precipitating sludge in the water process, mud-water separation is effective, and sludge settling speed is fast, collection efficiency is high.
Description of drawings
Fig. 1 is structural representation of the present utility model
The specific embodiment
As shown in Figure 1, a kind of activated sludge separator, comprise mud collecting pit 1, two water inlet pipes 2, mud return line 3 and sludge reflux pumps 4, the water side of described water inlet pipe 2 is provided with elbow 2b, delivery port 2c is vertical with the vertical body 2a of water inlet pipe, delivery port 2c is over against the vertical inner wall 1a of mud collecting pit 1, and mud return line 3 is communicated with mud collecting pit 1 bottom, and mud return line 3 connects sludge reflux pumps 4.The delivery port 2c of described water inlet pipe 2 is positioned at mud collecting pit 1 middle part, the inwall 1a at mud collecting pit 1 middle part is provided with current buffering net 5, the plane 5a of this current buffering net becomes 30 ° of angles with the inwall 1a at mud collecting pit 1 middle part, the plane 5a of current buffering net is towards mud collecting pit 1 bottom, can slow down flow rate of water flow, reduce water flow dynamic energy, alleviate the amount of filling up of precipitating sludge.Described mud collecting pit 1 bottom is taper, and the angle between taper surface 1b and mud collecting pit bottom surface 1c is 60 °.Facilitate sludge settling and quick collection, improve mud and collect and backflow efficient.
