Further, bottom is equipped with back taper and stores bucket 16 in the sedimentation and filtration ditch 8.
Further, the aerator 13 has multiple.
Referring to Fig. 1, in normality sewage treatment, its working principles are as follows:
First, sewage or waste water to be processed enters in anaerobic pond 2 from water inlet 1, and anaerobic organism occurs in anaerobic pond 2 Reaction, the main function of anaerobic organism reaction include: that insoluble organic matter is become dissolved organic matter, by bio-refractory Organic matter becomes the organic matter of bio-degradable, organic nitrogen is become ammonia nitrogen;And sludge excessive in the anaerobic pond 2 can be from described Mud discharging mouth 14 is discharged;
Second, the sewage after the interior processing reaction of the anaerobic pond 2 stays for some time enters in the aerobic tank 4 and occurs Oxygen biological respinse, and the main function of aerobe reaction includes: the organic matter consumed in water, reduces COD COD;It will Ammonia nitrogen is transformed into nitrate nitrogen, and part nitrate nitrogen is converted to nitrogen by the denitrifying bacterium in biomembrane and realizes sewage water denitrification;PolyP bacteria will be dirty Phosphate conversion in water is biological sludge, realizes sewage dephosphorization;And the aerobic state in anaerobic pond 2 is by blower 5, aeration air 6 pipe 12, aerator 13 and shut-off valve job controls, the pressure-air which provides are delivered to through being aerated air hose 12 Aerator 13, and air forms micro-bubble through aerator 13 and enters in the aerobic tank 4 in water, and then realizes to aerobic Aeration and oxygenation for sewage in pond 4;
Third, sewage reacts in aerobic tank 4 stay for some time after enter bottom in sedimentation and filtration ditch 8, and precipitated Sludge in filter tank 8 in sewage is deposited separation in bottom in sedimentation and filtration ditch 8, and partially the sludge of precipitation and separation does not pass through Filter layer 9 is isolated by filtration, and the clear water obtained after filtering is discharged from the clear water discharge outlet 10 on sedimentation and filtration ditch, and precipitates filtering The sludge of bottom is by 5 gas stripping of blower in pond 8, and then realizes and successively pass through base sludge in the sedimentation and filtration ditch 8 Air lift sludge pipe 11 and mud return line 3 flow back into the anaerobic pond 2 and flow back into anaerobic pond 2.
In addition, and when the present apparatus when sedimentation and filtration ditch 8 run a period of time after, which is filtered by sludge blockage Duct, filtration resistance become larger, and need to backwash filter layer.
Referring to fig. 2, the utility model is when backwashing processing to filter layer 9, its working principles are as follows: it is empty first to close aeration 12 shut-off valve 6 on tracheae, the aerobic tank 4 stop aeration, since shut-off valve 6 is closed, enter the aeration air hose 12 originally Air can enter in the air lift air hose 7, and increase air lift sludge pipe 11 to the water of bottom in sedimentation and filtration ditch 8 and The pumping velocity of mud, so that negative pressure is formed on bottom in sedimentation and filtration ditch 8, the clear water of top is fast from top to bottom in sedimentation and filtration ditch 8 Speed flows through filter layer 9, and the sludge in filter layer 9 enters bottom in sedimentation and filtration ditch 8 with flushing water stream, arranges finally by air lift Mud and fully enter anaerobic pond.When the clear water stream of top in sedimentation and filtration ditch 8 is complete, shut-off valve 6, the aeration air hose 12 are opened It opens, which operates normally, and the suction capactity of the air lift sludge pipe 11 weakens, and the filter layer 9 backwash terminates And it is restored to normality work.Therefore it can realize to start when the filtration resistance of filter layer 9 reaches preset value and filter layer 9 is carried out instead It rinses.
In addition, in the utility model when backwashing processing to filter layer 9, between the aerobic tank 4 and sedimentation and filtration ditch 8 Training wall 17 close or the anaerobic pond 2 and 4 connectivity part of aerobic tank close or anaerobic pond 2 in do not add the modes such as sewage. Water level can reduce or keep low level in the aerobic tank 4 described in this way, and the water in the aerobic tank 4 cannot enter sedimentation and filtration ditch 8 It is interior, therefore do not have new sludge and enter in the sedimentation and filtration ditch 8, and then can realize the sludge of bottom in sedimentation and filtration ditch 8 By in total reflux to the anaerobic pond 2.
The preferred embodiments of the present invention have been described in detail above.It should be appreciated that the ordinary skill people of this field Member according to the present utility model can conceive without creative work makes many modifications and variations.Therefore, all this technology necks Technical staff passes through logic analysis, reasoning or limited reality according to the design of the utility model on the basis of existing technology in domain Available technical solution is tested, it all should be within the scope of protection determined by the claims.
