After processing, can make the mud in anoxic pond 4 and aerobic tank all can have part to be deposited in secondary settling tank 5 with sewage, into
And the mud in anoxic pond 4 and aerobic tank is caused constantly to reduce, microorganism reduction is also just represented, anoxic pond 4 is will affect and becomes reconciled
Sludge reflux in secondary settling tank 5 can be supplemented in anoxic pond 4 and aerobic tank by the wastewater treatment efficiency in oxygen pond in this way, on the one hand
Anoxic pond 4 and the normal good carry out sewage treatment of aerobic tank, another aspect is allowed also to be avoided that excessive sludge is heavy
Product influences its normal use, and the organic matter carbon in the nitrate and water inlet brought into the mixed liquor to flow back in secondary settling tank 5
Source carries out denitrification, makes to be reduced into N2 into NO2-, NO3- in water and reaches denitrification, ammonia of degrading while removing organic matter
Nitrogen.
As shown in Fig. 2, being equipped with aeration tube 11 in the bottom of aerobic tank, while 11 one end of aeration tube is connected with Aeration fan
12, by Aeration fan 12, aeration is realized in gas transmission in aeration tube 11, and biologic packing material 13, filler are lifted in aerobic tank
Specific surface area is 160m2/m3, which can be by the microorganism in mud in 15:1 or so, such aeration tube 11
It up blows and is attached on biologic packing material 13, so that dirty Organic substance in water more comprehensively can efficiently resolve into inorganic matter,
Wastewater treatment efficiency is more preferable and more efficient；In addition wherein aerobic tank includes that the first aerobic tank 18 and second for being set side by side is aerobic
Pond 19, sewage need just enter secondary settling tank 5 after the first aerobic tank 18 and the second aerobic tank 19, extend sewage good
The locating time in oxygen pond, can be preferably processed, on the other hand setting meeting in this way is so that the second aerobic tank 19 would generally compare
First aerobic tank 18 is limpider, and then can slow down the deposition of deposit in secondary settling tank 5, to reduce subsequent processing secondary settling tank
The frequency of deposit in 5.
After prolonged sewage treatment, it is heavy after anoxic pond 4 and aerobic tank processing to lead to be eventually deposited at two
Sediment in pond 5 is cumulative, if deposition excessively will affect the use of secondary settling tank 5, therefore is provided in the side of secondary settling tank 5
Sludge digestion tank 14 is provided with time mud pipe 15 for being connected to the two between sludge digestion tank 14 and secondary settling tank 5, return the leaching of 15 one end of mud pipe
Not before the liquid level of secondary settling tank 5 and it is located at 5 bottom of secondary settling tank, the snorkel for passing to back mud pipe 15 is connected on aeration tube 11
16, air valve 17 is provided on snorkel 16, aeration tube 11 is again provided with air valve 17 on the pipeline of aerobic tank side, this
Sample opens the air valve 17 on snorkel 16 during aeration, and snorkel 16 has the air of pressure to enter back from snorkel 16
Mud pipe 15, gas and liquid are thoroughly mixed to form gas-liquid mixture, since the density ratio liquid of gas-liquid mixture is small, cause back mud
15 inside and outside differential pressure of pipe is kept away to make the mud mixed liquid body in secondary settling tank 5 be back to sludge digestion tank 14 from the promotion of mud pipe 15 is returned
Exempt from too many deposits in secondary settling tank 5, keeps the normal use of secondary settling tank 5, carried out in this pond in sludge digestion tank 14
Aerobic sigestion, periodic cleaning is as agricultural fertilizer processing after a small amount of lime slaking can be added to sterilize.
As shown in figures 3 to 6, wherein primary sedimentation tank 3 and 14 bottom of sludge digestion tank is tapered and bottom is provided with outlet
20, and export and be provided with exhaust-valve 21 at 20, it is conducive to by the deposit buildup in pond at outlet 20 in this way, convenient for subsequent
Cleaning, it is simple and convenient by opening exhaust-valve 21 when needing to clean up the sediment in pond；In addition connect on primary sedimentation tank 3
It is connected to the sewage pump 22 in sewage lifting to primary sedimentation tank 3, Siphon pot 23 is connected on sewage pump 22, by siphon
The setting of tank 23, will can fill water in advance in Siphon pot 23, sewage pump 22 works the sky of 23 inlet pipeline of Siphon pot
Gas is taken away, so that forming vacuum state in inlet pipeline, the sewage of underground can enter Siphon pot under atmospheric pressure at this time
23 are promoted to again in primary sedimentation tank 3, complete the case where extracting depth underground hydrodynamic(al) work, sewage pumping is avoided not come up.
As shown in fig. 6, the disinfecting mechanism being arranged at discharge outlet 7 is ultraviolet ray sterilizer 24, disinfection by ultraviolet light is used
Without chemicals, THMs class disinfection by-products will not be generated, and bactericidal effect is fast, odorless also noiseless, follow-up operation
It is low with maintenance cost.
As shown in fig. 7, wherein the top of biologic packing material 13 is provided with lantern ring 25, and cross bar 26 is lifted on by lantern ring 25
On, and be suspended on aerobic tank inner wall by cross bar 26, wherein mounting blocks 27 are fixed on aerobic tank inner wall, the mounting blocks 27
On be provided with and place the L-shaped groove 28 being packed into for cross bar 26, not only can realize the fast quick-detach of cross bar 26, and horizontal after being packed into
Bar 26 is less prone to the case where vibration up and down, and wherein lantern ring 25 is slidably connected on cross bar 26, may be implemented to biologic packing material 13
The adjustment of position, and be threaded on lantern ring 25 screw 29 for pushing against cross bar 26, is realized pair by tightening screw 29
The limit of lantern ring 25, lantern ring 25, which is less prone to movement, when being maintained at working condition causes the position of biologic packing material 13 to shift.
The course of work: by starting sewage pump 22 after pouring water in Siphon pot 23 by sewage lifting into primary sedimentation tank 3,
Then sewage successively passes through anoxic pond 4 and enters back into the first aerobic tank 18, the second aerobic tank 19, opens Aeration fan 12 and opens aeration
Air valve 17 on pipe 11 realizes aeration to the first aerobic tank 18 and the second aerobic tank 19, and then sewage enters secondary settling tank 5, finally from
Discharge outlet 7 is discharged and outdoor is discharged by ultraviolet ray sterilizer 24, during which selectively turns on sludge reflux pump 10 for two
Sludge reflux in heavy pond 5 is into anoxic pond 4 and aerobic tank, when deposit is too many in secondary settling tank 5, by opening snorkel 16
On air valve 17, partial sludge in secondary settling tank 5 is mentioned into sludge digestion tank 14 and is recycled.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but
As long as all by the protection of Patent Law in the scope of the claims of the utility model.
