The sludge reflux pump for the sludge of second pond to be back to anaerobic pond, described dephosphorization pond are also associated between pond and anaerobic pond
Dephosphorization agent adding set is also associated with, fiber rotary disc filter is provided with described filtering ponds, filtering ponds are also associated with being used for
Sludge is back to the backwashing pump of sludge-tank.
Preferably, described anoxic pond, contact-oxidation pool, second pond, dephosphorization pond, filtering ponds are provided with blow-down pipe.
Preferably, described contact-oxidation pool is provided with two.
Preferably, described sludge reflux pump is provided with two.
Preferably, described mixed-liquor return pump is provided with two.
By adopting the above-described technical solution, the beneficial effects of the utility model are：
Sanitary wastewater processing equipment of the present utility model, Aerobic Pond can increase microorganism retention using filler, improve system
The organic loading of system；Catalytic oxidation pool side enters side and gone out, and in the absence of intermittent operation, requires relatively low to operation；Set up dephosphorization and rotating disk
Formula mechanical filtration systems, it is ensured that stable water outlet reaches one-level A marks, and the technique cost is far below MBR techniques, and later maintenance expense
It is relatively low to operating personnel's technical requirements with low；Assisted automated system, manual operation load are few, it is only necessary to part-time regular visit.

Embodiment
Reference picture 1-3, a kind of sanitary wastewater processing equipment of the present utility model, including be sequentially connected anaerobic pond 1, anoxic
Pond 2, contact-oxidation pool 3, second pond 4, dephosphorization pond 7, filtering ponds 10 and ultraviolet ray disinfector 11, described contact-oxidation pool 3 with
The mixed-liquor return pump 6 for mixed liquor in contact-oxidation pool 3 to be back to anoxic pond 2, anoxic pond are provided between anoxic pond 2
2 are respectively connected with blower fan with contact-oxidation pool 3, are also associated between described second pond 4 and anaerobic pond 1 for by second pond 4
Sludge is back to the sludge reflux pump 5 of anaerobic pond 1, and described dephosphorization pond 7 is also associated with dephosphorization agent adding set 8, described mistake
Fiber rotary disc filter is provided with filter tank 10, filtering ponds 10 are also associated with the backwashing pump for sludge to be back to sludge-tank
9。
Anoxic pond 2, contact-oxidation pool 3, second pond 4, dephosphorization pond 7, filtering ponds 10 are provided with blow-down pipe.
In order to improve waste water treatment efficiency, contact-oxidation pool 3 is provided with two；Sludge reflux pump 5 is provided with two；Mixing
Liquid reflux pump 6 is provided with two.
Anaerobic pond 1, which is mainly used in difficult degradation, the hydrolysis acidification of thing, with the improvement of living standards kitchen in sanitary wastewater
And the increase of washes proportion, hardly degraded organic substance increase, can be effective by the Hydrolysis Acidification that the residence time is shorter
Degraded larger molecular organicses are small-molecule substance, reduce the energy consumption of aerobic process.Aerobic sludge anaerobism is made by sludge reflux, had
Beneficial to the release of phosphorus containg substances, condition is provided for follow-up aerobic phosphorus absorption, makes full use of biological dephosphorization, lowers chemical feeding quantity.Anaerobism is stopped
The time is stayed to be arranged to 1h
Anoxic pond 2 is used to remove total nitrogen setting, by the mixed liquor for the Aerobic Pond that flows back, is adsorbed into anoxic high load capacity,
Reach the purpose of removing total nitrogen.
Aerobic Pond is digestion, drop using the aerobic microbiological in sewage under the conditions of having free oxygen (molecular oxygen) existing
The organic matter in sewage is solved, it is stabilizing it, innoxious.This project Aerobic Pond is the form of contact-oxidation pool 3, and pigtail is set in pond
Band filler, oxygenation sewage submerges whole fillers, and flows through filler with certain flow velocity.A microorganism part is in the form of biomembrane
Be bonded to filler surface, it is a part of then suspended in water with cotton-shaped, therefore it has biofilter and activated sludge process concurrently the characteristics of.
The oxygen that Chi Zhong Institute of Micro-biology needs is supplied by artificial aeration.After biofilm development to certain thickness, the microorganism of nearly filler wall will
Anaerobic metabolism is carried out due to anoxic, the souring that caused gas and aeration are formed causes part biological film to come off, promoted
The growth of neoformation film, form the metabolism of biology.The biomembrane to come off enters follow-up second pond 4 with water outlet.
The main function of second pond 4 carries out mud-water separation, is flowed back by the sludge part after concentration excess activated sludge discharged,
Supernatant is handled into next stage.
Dephosphorization pond 7 does not reach preferable treatment effect, it is necessary to set chemical dephosphorization device by biochemical system dephosphorization, passes through
Chemicals dosing plant adds dephosphorization agent, reduces the TP contents in water.
Add in the waste water after dephosphorization agent needs further to remove containing a large amount of SS, by setting the fiber of micro-filtration rank to turn
Disk filter, the SS in filtering appts make water outlet SS be far below 10, effect stability.
By setting the disinfection by ultraviolet light of no reagent consumption, have the function that to reduce Escherichia coli in water.Low SS water quality
Middle-ultraviolet lamp is better than other disinfection way.
Sanitary wastewater processing equipment of the present utility model, can be added waste water into anaerobic pond 1, so by waste water lifting pump
After pass sequentially through anoxic pond 2, contact-oxidation pool 3, second pond 4, dephosphorization pond 7, filtering ponds 10 and ultraviolet ray disinfector 11, locate successively
After reason, the standard of finally reaching is discharged.
