Greatly, small turbulence structure is exported, can effectively guide fluid quickly through when fluid passes through flow-disturbing partition bottom end, due to circulation
Sectional area is smaller, and the layering of sludge and sewage is disturbed, and sludge is forced to be sufficiently mixed with sewage, promotes oxygen compatibility pool and subsequent
The MLSS value of reaction tank, improves the rate of each reaction tank especially nitration reaction.
Optionally, the main water inlet tube 7, anaerobic pond 4, anoxic pond 3, aerobic as shown in Figure 1, the application further includes tank body
Pond 1, the first oxygen compatibility pool 5, the second oxygen compatibility pool 6, sedimentation basin 11, water outlet 13, preposition anoxic pond 9, sludge concentration tank 10 are respectively provided with
In the tank body.Will integrated rural sewage-treatment plant associated with entire AAO and SBR technique be arranged in a tank body
Interior, the volume of tank body can be designed according to sewage treatment capacity；Sewage-treatment plant is provided entirely in tank body, overall structure
It is compact, facilitate whole Transporting and installation.
Optionally, one end of the tank body is arranged in the aerobic tank 1, and the sedimentation basin 11 is arranged with water outlet 13 in institute
State the other end of tank body, first oxygen compatibility pool 5 and the second oxygen compatibility pool 6 are arranged side by side, first oxygen compatibility pool 5 and second simultaneous
The one end in oxygen pond 6 connects with the aerobic tank 1, the other end of first oxygen compatibility pool 5 and the second oxygen compatibility pool 6 with it is described
Sedimentation basin 11 connects, and the anoxic pond 3, anaerobic pond 4, preposition anoxic pond 9, sludge concentration tank 10 are sequentially arranged simultaneous described first
Region between oxygen pond 5 and the second oxygen compatibility pool 6, the anoxic pond 3 connect with the aerobic tank 1, the preposition anoxic pond 9 with
The sedimentation basin 11 connects.Two oxygen compatibility pools are arranged in two sides, so that entire sewage-treatment plant topology layout is reasonable, occupy empty
Between it is small, convenient transportation, installation occupies little space, stronger to the adaptability of installation environment, convenient to promote in vast rural area region
It uses.
It optionally, further include Rinsing Area 12, the Rinsing Area 12 is arranged between the sedimentation basin 11 and water outlet 13,
The supernatant of the sedimentation basin 11 enters the water outlet 13 through the Rinsing Area 12.Supernatant after i.e. sedimentation basin 11 precipitates is first
Into Rinsing Area 12, then it is discharged again by Rinsing Area 12 into water outlet 13, Rinsing Area 12 can play certain buffer function,
The sludge in sedimentation basin 11 is prevented to be discharged.
For convenience of the application is understood, referring to the main working process for shown in Fig. 2, introducing the application: sewage from
After main water inlet tube 7 enters, fraction sewage respectively enters 9, two oxygen compatibility pools of preposition anoxic pond, and most of sewage, which is directly entered, to be detested
Then 4 bottom of oxygen pond sequentially enters anoxic pond 3, aerobic tank 1, the first oxygen compatibility pool 5 or the second oxygen compatibility pool 6, sedimentation basin 11, clear water
Slot 12, water outlet 13 see which oxygen compatibility pool is in operating status, which oxygen compatibility pool are entered after the water in aerobic tank 1 comes out；
The supernatant of oxygen compatibility pool enters sedimentation basin 11, and the partial reflux liquid of oxygen compatibility pool enters sludge concentration tank 10；The supernatant of sedimentation basin 11
Liquid enters Rinsing Area 12, and the returned sludge after precipitating enters sludge concentration tank 10；The supernatant of sludge concentration tank 10 passes through supernatant
Liquid return pipe 8 is sent to anoxic pond 3, and the sludge after concentration is sent to preposition anoxic pond 9, then enters anaerobism from preposition anoxic pond 9 again
Pond 4.In this way, denitrification on the one hand can be carried out, dissolved oxygen and nitric acid in reflux thickened sludge on the other hand can be first consumed
Salt, the anoxic then to carry out put phosphorus and provide more favorable condition.Sewage is after above-mentioned process from 13 row of water outlet
Out, sludge, phegma etc. continue to participate in subsequent sewage disposal process；This process is directed to the biggish feelings of sewage inlet
Condition, when sewage inlet is smaller, most sewage is directly entered that oxygen compatibility pool being currently running, oxygen compatibility pool after treatment
It is discharged into sedimentation basin 11, Rinsing Area 12, through water outlet 13, preposition anoxic pond 9, anaerobic pond 4, another oxygen compatibility pool are then only few
It measures sewage to enter, conserves the stage into small flow.
