Description
Technical field：
It the utility model is related to a kind of precipitation return-flow structure of activated sludge in sewage disposal system.
Background technology：
Stevia rebaudian leaf can produce waste water, the COD of the waste water during Steviosin is extracted（COD）For 1000~
2000, if the waste water directly is delivered into sewage treatment plant, the waste water can turn into new pollution sources and make in course of conveying
Into the pollution of other water bodys, increase post-processing difficulty, and processing cost can be increased.
Sewage disposal system can often use during above-mentioned sewage is handled and arrive activated sludge, activated sludge is dirty in purification
, it is necessary to be precipitated to activated sludge to reuse after water, the precipitation of existing activated sludge is directly entered in sedimentation basin
OK, flow-disturbing is carried out to waste water in sedimentation basin by agitating paddle incessantly, flow-disturbing is easy to activated sludge to be precipitated to the bottom of sedimentation basin
On face, then the activated sludge of precipitation is evacuated in aeration tank by pump and recycled, above-mentioned removal process needs not
That stops uses agitating paddle and pump, and cost is very high, and the activated sludge of fine granularity is not easy to precipitate, and is eventually drained off, no
But waste and new pollution sources can be turned into.
The content of the invention：
The utility model is provided living in a kind of sewage disposal system to solve the above-mentioned problems of the prior art
The precipitation return-flow structure of property sludge.
There is technical scheme used by the utility model：The precipitation backflow knot of activated sludge in a kind of sewage disposal system
Structure, including precision processing pond and sedimentation basin, gutter, aqueduct, hanging plate, lanyard and packing box are provided with the precision processing pond, if
Lanyard button described in dry root is on hanging plate, and every lanyard higher slice is provided with some packing boxs, and gutter is placed in above hanging plate, and is drawn
The delivery port of tank is connected with aqueduct, and one end of aqueduct through precision processing pond side wall and is stretched in sedimentation basin；
Baffle plate, taper stillpot, return main and backflow branch pipe are provided with the sedimentation basin, several described taper precipitations
Groove is located at the bottom of sedimentation basin, and baffle plate is located at the side of aqueduct upper water-out mouth, and some backflow branch pipes are connected to return main
On, and every backflow branch pipe is correspondingly stretched in a taper stillpot, one end of return main through sedimentation basin side wall and is stretched
In outside sedimentation basin.
Further, the height of the baffle plate and the height of stillpot are equal.
Further, the sedimentation basin is provided with drainage.
The utility model has the advantages that：
The activated sludge of fine granularity and Block activated sludge are separately precipitated in the utility model, reduce pollution and wave
Take, and precipitation process is realized by the sputtering of current itself flow velocity, avoids using agitating paddle, and it is also to pass through current to reclaim
To realize, electric energy is saved, greatly saves cost.
Brief description of the drawings：
Fig. 1 is the utility model structure chart.
Embodiment：
The utility model is further described below in conjunction with the accompanying drawings.
As shown in figure 1, in a kind of sewage disposal system of the utility model activated sludge precipitation return-flow structure, including essence at
Pond 3 and sedimentation basin 4 are managed, gutter 31, aqueduct 32, hanging plate 33, lanyard 34 and packing box 35, hanging plate are provided with precision processing pond 3
33 on the inwall in precision processing pond 3, and some buttons of lanyard 34 are provided with some on hanging plate 33 in the every higher slice of lanyard 34
Packing box 35, gutter 31 is placed in the top of hanging plate 33, and the delivery port of gutter 31 is connected with aqueduct 32, aqueduct 32
One end passes through the side wall in precision processing pond 3 and stretched in sedimentation basin 4.
Baffle plate 41, taper stillpot 42, return main 43 and backflow branch pipe 44, several tapers are provided with sedimentation basin 4 to sink
Shallow lake groove 42 is located at the bottom of sedimentation basin 4, and baffle plate 41 is located at the side of delivery port in aqueduct 32, and some backflow branch pipes 44 connect
In on return main 43, and every backflow branch pipe 44 is corresponding stretches in a taper stillpot 42, and one end of return main 43 is worn
Cross the side wall of sedimentation basin 4 and stretch in the aeration tank in sewage disposal system.
The height of baffle plate 41 in the utility model and the height of stillpot 42 are equal.
When in use, activated sludge is conveyed in the aeration tank into sewage disposal system, the sewage in aeration tank is from aeration
In pond top overflow to precision processing pond 3.The activated sludge of the fine granularity in sewage in precision processing pond 3 can be adsorbed to packing box
On 35, the sewage after filled disk 35 adsorbs becomes primary water, is gradually stepped up with the water level of the primary water, primary water can enter
In gutter 31, block activated sludge can be entered in sedimentation basin 4 by aqueduct 32 together with primary water in primary water.Draw
During primary water in water pipe 32 drains into sedimentation basin 4, primary water can produce sputtering on baffle plate 41, and the sputtering can to arrange
The Block activated sludge in primary water into sedimentation basin 4 disperses, and the activated sludge after disperseing is precipitated in taper stillpot 42.
The high setting such as baffle plate 41 and stillpot 42, while ensureing to sputter effect, and can ensures that the activity after sputtering is dirty
Mud is preferably dropped down onto in stillpot 42.Baffle plate 41 is easy to activated sludge to disperse, and avoids activated sludge accumulation agglomerating, and baffle plate 41 rises
Acted on to flow-disturbing, save paddle, save the energy.
Activated sludge in taper stillpot 42 is due to the effect of the flow-disturbing of baffle plate 41 and the flow direction of primary water itself, activity dirt
Mud can followed by part primary water and be back in backflow branch pipe 44, and entered by return main 43 in aeration tank and carry out repeating profit
With avoiding wasting.
It is provided with drainage 400 on sedimentation basin 4, the primary water in sedimentation basin 4 flow to sewage treatment plant by drainage 400
It is further processed.
Described above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art
For art personnel, some improvement can also be made on the premise of the utility model principle is not departed from, these improvement also should be regarded as
The scope of protection of the utility model.
