Brief description of the drawings
Fig. 1 is full biological denitrificaion of the present utility model and mud decrement system schematic.
Embodiment
In order that the purpose of this utility model, technical scheme and advantage are clearer, below in conjunction with the accompanying drawings and specific implementation
The utility model is described in detail example.
As described in Figure 1, full biological denitrificaion of the present utility model and mud decrement system 100, including reaction tank 1, be connected to
Water inlet 2 on the side wall of reaction tank 1 and the delivery port 3 higher than the water inlet 2.Sewage enters reaction tank 1 from water inlet 2
After being handled full biological denitrificaion and mud decrement system 100 are discharged by delivery port 3.
Specifically, the reaction tank 1 is included positioned at the sludge memory block 11 of the bottom of reaction tank 1, positioned at the sludge
The aeration reaction zone 12 of the top of memory block 11, the exhaust emissions area 13 positioned at the top of aeration reaction zone 12, exposes positioned at described
Simultaneously enclosed by the first dividing plate 14, second partition 15 and the side wall of reaction tank 1 and set the settling zone 16 formed in the side of solid/liquid/gas reactions area 12；Described
There is the passage 17 for connecting the aeration reaction zone 12 and the settling zone 16 between one dividing plate 14 and the second partition 15；Institute
State water inlet 2 with the aeration reaction zone 12 to be connected, the delivery port 3 is connected with the settling zone 16.
The full biological denitrificaion and mud decrement system 100 are also including being communicated in the aerator of aeration reaction zone 12 (not
Diagram) and for adjust aeration flow regulating valve；Dissolved oxygen concentration in the aerated reaction pond 1 for 0.5mg/L~
1.0mg/L.The aerated reaction pond 1 is oxygen compatibility pool, and the aeration reaction zone 12 is arranged at the top of the sludge memory；Cause
This is filled with oxygen into aeration reaction zone 12 when handling sewage, and the tail gas of generation is then discharged upwards via exhaust emissions area 13,
The sludge of formation is dropped downward into sludge memory block 11, and the tail gas of rising does not interfere with or stirred micro- life of sludge memory block 11
Thing, has built a good anaerobic biological environment.
Wherein, first dividing plate 14 and the second partition 15 by the settling zone 16 and the aeration reaction zone 12 and
The exhaust emissions area 13 keeps apart, and forms the space that a relative airless is disturbed, is easy to sewage to be separated with sludge.And
And, first dividing plate 14 is obliquely installed in bell mouth shape or cone-shaped with the second partition 15, is facilitated in settling zone 16
Sludge is slid to the aeration reaction zone 12 downwards, without stirring or the device of promotion sludge, and can prevent from blocking logical
Road 17.
The structure and setting form of first dividing plate 14 and the second partition 15 are not limited, and can form a variety of as needed
Structure type has the settling zone 16 of isolation features.For example in the present embodiment, the side of first dividing plate 14 and the reaction tank 1
Wall is parallel, and the side wall of the second partition 15 and the reaction tank 1 intersects, and the second partition 15 less than described first every
Plate 14；The passage 17 is arranged at the intersection of first dividing plate 14 and the second partition 15, and the sewage for for handling well enters
Enter the sludge reflux after settling zone 16 and precipitation to aeration reaction zone 12.It is wherein so-called parallel, refer to that bearing of trend is big
Body is consistent, vertically extends；So-called intersection refers to that side wall vertically extends, and second partition 15 prolongs in the horizontal direction
Stretch, both are in vertical or approximately perpendicular state.Certainly, first dividing plate 14 and the second partition 15 can also be it
His shape, for example the first dividing plate 14, which differs, is set to parallel or less parallel, it is also possible to tilt or a part of parallel
A part is tilted, as long as playing buffer action；Similarly second partition 15 can also do corresponding change.
In use, treatment sewage initially enters the aeration reaction zone 12 of reaction tank 1, while using aeration mode to aeration
Reaction zone 12 is oxygenated, and rationally controls dissolved oxygen by adjusting aeration quantity, aeration reaction zone 12 presents and oxygen condition, makes to have in sewage
Machine thing is degraded under microbial action, while the ammonia nitrogen in water changes into nitrogen in the presence of nitrobacteria and denitrifying bacteria
Removed from water, so as to realize that nitrification-denitrification is synchronous, the tail gas that aeration is produced is discharged by exhaust emissions area 13.
Sewage after processing enters settling zone 16 by the passage 17 between the first dividing plate 14, second partition 15, through mud
Discharged after water separation from delivery port 3, while sludge is fallen after rise to aeration reaction zone 12.Biological treatment produce biochemical sludge accumulate in
Sludge memory block 11, in anaerobic state, it is organic small that the partial sludge produces substantial amounts of volatile fatty acid etc. by anaerobic digestion
Molecule, the part organic molecule can provide high-quality carbon source for the biological denitrification process of aeration reaction zone 12, while sludge quantity sheet
Body is reduced, so as to realize the dual purpose of full biological sewage denitrogenation and mud decrement.
