Description of the drawings
Fig. 1 is the structural schematic diagram of rural sewage treatment system provided by the invention.
Specific implementation mode
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes, it is clear that the described embodiments are merely a part of the embodiments of the present invention, instead of all the embodiments.
Referring to Fig. 1, being the structural schematic diagram of rural sewage treatment system 1 provided by the invention.
The rural sewage treatment system 1 includes the oil separator 2 for passing sequentially through pipeline connection, septic tank 3, regulating reservoir 4, detests
Oxygen biochemistry pool 5, anoxic biochemistry pool 6, contact-oxidation pool 7, sedimentation basin 8, artificial swamp 9.
The oil separator 2, the height of the regulating reservoir 4 are above the septic tank 3, and the regulating reservoir 4 is to described artificial
The height of wetland 9 gradually reduces.
Sewage is flow to by the oil separator 2 in the septic tank 3 by gravity, and sewage is by elevator pump 31 by describedization excrement
Pond 3 is promoted in the regulating reservoir 4, and sewage has the regulating reservoir 4 to flow to successively in the artificial swamp 9 by gravity.
The contact-oxidation pool 7 is equipped with sewage backflow and pumps 71, and part sewage lifting in pond is returned the anoxic biochemistry pool 6.
Aerator 72 is additionally provided in the contact-oxidation pool 7.The sedimentation basin 8 is equipped with sludge reflux pump 81, and partial sludge is promoted
Go back to the anaerobic biological pond 5.
The rural sewage treatment system 1 further includes PLC control system 10, if there are four contact-making switch, respectively with it is described
Elevator pump 31, sewage backflow pump 71, the aerator 72, the sludge reflux pump 81 are connected by circuit.
The anaerobic biological pond 5, the anoxic biochemistry pool 6 are equipped with biofilm packing in the contact-oxidation pool 7, and
Using soft cellulose filler.
Based on the treatment method for rural sewage of the rural sewage treatment system 1, include the following steps：
S01：Food waste waste water is normally comprised in sewage, oil content is higher.Sewage is passed first into the oil separator 2, carry out every
Oil removes Slag treatment.
The oil separator 2 also adds demulsifier into sewage, and continues to be aerated, and the oil emulsion in sewage is made to agglomerate for oil
Drop removes together during oil removal removes Slag treatment.
S02：Open the water outlet of the oil separator 2, treated that sewage is discharged under Gravitative Loads is described for oil removal slagging-off
In septic tank 3.
The septic tank 3 uses three compartment septic tanks.Because proportion different sewage is divided into three layers naturally, upper layer is lighter floats
Foam, lower layer are deposited as organic sludge, and middle level is opposite settled sewage.Middle level sewage is flow in next lattice, is repeated the above,
The residue left then continues anaerobic fermentation.To being more settled sewage in third lattice.
The organic sludge of periodic cleaning deposition, is used as organic fertilizer.
S03：By the sewage in 3 third lattice of the septic tank, the regulating reservoir 4 is promoted to by the elevator pump 31,
It is kept in the regulating reservoir 4.
Under the buffering of the regulating reservoir 4, the sewage water quantity holding for being emitted into subsequent processing is stablized；Different time sections, no
It is mixed between the sewage of same type, sewage quality is made also to keep relatively stable, balanced state.
Meanwhile the sewage kept in the regulating reservoir 4 also produces preliminary hydrolysis acidification.
S04：Under the buffering of the regulating reservoir 4, sewage is emitted into constant rate in the anaerobic biological pond 5.Institute
The sludge in sedimentation basin 8 is stated also to be back in the anaerobic biological pond 5.Control is back to the sludge quantity in the anaerobic biological pond 5,
It avoids introducing excessive nitrate nitrogen and enters and release phosphorus bacterium competition carbon source.
The anaerobic biological pond 5 is not aerated, and the dissolved oxygen in microbial consumption sewage, dissolved oxygen content is reduced to
0.2mg/L is hereinafter, form anaerobic environment.
It under the action of anaerobe, hydrolyzes, be acidified in sewage, production acetic acid, methane phase are carried out at the same time.It is suitably adjusted in processing
PH is saved, sewage is made to keep neutral.
It is removed through most COD in treated in the anaerobic biological pond 5 sewage, larger molecular organics also resolve into small point
Sub- organic matter.
S05：In sewage discharge to the anoxic biochemistry pool 6 after Anaerobic Treatment.Sewage in the contact-oxidation pool 7
After being mixed with the sewage from the anaerobic biological pond 5, it is back in the anoxic biochemistry pool 6.
Sewage in the contact-oxidation pool 7 contains higher dissolved oxygen content, and control is back to the anoxic life
The sewage quantity for changing pond 6, makes dissolved oxygen content in the anoxic biochemistry pool 6 form stable anaerobic environment in 0.5mg/L or so.
Denitrifying bacterium in the anoxic biochemistry pool 6 using the sewage newly entered in abundant organic matter make carbon source carry out it is anti-
Nitration reaction, by a large amount of nitrate nitrogens in backflow mixed liquor（NO3-N）And nitrite nitrogen（NO2-N）Be reduced to N2 discharge to
Air realizes the denitrogenation of sewage.Remove part BOD simultaneously.
S06：In sewage discharge to the contact-oxidation pool 7 after anoxic treatment.Pass through institute in the contact-oxidation pool 7
It states aerator 72 to be persistently aerated, makes dissolved oxygen content in 2mg/L or more, form stable aerobic environment.
Under aerobic environment, organic matter is by the further biochemical degradation of aerobic microbiological；PolyP bacteria absorbs the phosphorus in sewage, turns
It is melted into insoluble poly orthophosphates to store in vivo, discharging excess sludge by sedimentation basin achievees the purpose that system dephosphorization.
Ammonia nitrogen（NH3-N）It is nitrified, concentration declines, nitrate nitrogen（NO3-N）, nitrite nitrogen（NO2-N）Concentration increase
Add.
Sewage in the contact-oxidation pool 7 is promoted back by sewage backflow pump 71 in the anoxic biochemistry pool 6, is made
Wherein dissolved oxygen, nitrate nitrogen（NO3-N）, nitrite nitrogen（NO2-N）Content rise.Stable anaerobic environment is formed to carry out
Anti-nitration reaction.
S07：In sewage discharge to the sedimentation basin 8 after Aerobic Process for Treatment, the suspended matter of each step accumulation is in institute before
State sedimentation separation in sedimentation basin 8.
Suspended substance sedimentation forms sludge blanket in bottom of pond, and the anaerobic biological pond 5 is promoted go back to by the sludge reflux pump 81
In, repeat anaerobism, anoxic, aerobic processing.
The sludge blanket of periodic cleaning deposition, is used as fertilizer after spontaneous fermentation.
S08：After precipitation process, most pollutant is processed in sewage, and clear water is passed through in the artificial swamp,
Carry out advanced nitrogen dephosphorization.And digging has wet well, convenient for water intaking.
Compared to the prior art, the rural sewage treatment system 1 provided by the invention fully utilize anaerobism, anoxic,
Aerobic Process for Treatment and Ecological Disposal, the perfect processing system of materializing strategy, the abundant larger molecular organics removed in sewage,
N, the pollutants such as P, COD.
To treated, sewage is used the rural sewage treatment system 1 provided by the invention, reduces water resource
Waste, while processing procedure generate sludge can be used as fertilizer, produce new economic benefit, the cost of system operation
Low, high efficiency.
Example the above is only the implementation of the present invention is not intended to limit the scope of the invention, every to utilize this hair
Equivalent structure or equivalent flow shift made by bright description is applied directly or indirectly in other relevant technology necks
Domain is similarly included within the scope of patent protection of the present invention.
