Description
Technical field
The present invention relates to a kind of sewage water treatment method and device, be specifically related at the villages and small towns sewage of a kind of high-efficient denitrification and dephosphorization
Reason method and device.
Background technology
" 12 " period, the sewage disposal in city is the most perfect, and the sewage disposal in villages and small towns is the most at the early-stage.Enter
After " 12 ", country puts into further raising to the policy guide of field of Environment Protection with strategy, and villages and small towns waste water control becomes water ring
One of emphasis that border is administered.Because life style and the difference of region, villages and small towns sewage is relative to municipal sewage, and its nitrogen, phosphorus contain
Amount fluctuating margin is relatively big, if not being effectively treated, easily causing the eutrophication of water body, particularly entering sensitive water when water outlet
When body or water outlet need reuse, the removal to nitrogen and phosphorus is the most extremely necessary.In actual motion, owing to scale and pipe network are invested
Limit, be difficult to wastewater reuse approach in rural area, the most generally use integrated buried device.Existing villages and small towns one
Changing sewage-treatment plant and mostly be AO, AAO technique, biological rotating disk technique and MBR technique etc., wherein AO, AAO technique and biology turn
The water outlet in terms of dephosphorization of dish technique is difficult to stably reach below 0.5mg/L, AO Process for Effluent total phosphorus in south generally more than 1mg/
L, is even up to more than 1.5mg/L at north water deficit area, and along with the change of temperature in season, runs and unstable；AAO technique
Although being better than AO technique with biological rotating disk technique, but also it is difficult to the most stably be down to 0.5 below mg/L；MBR Process for Effluent
Water quality is more stable, but pollutant should be removed in existing MBR technique MBR pond, realizes mud-water separation again, and operating cost is high, and film is easy
Polluting, maintenance management is complicated；Denitrogenating aspect particularly total nitrogen, above-mentioned several techniques are the most difficult to be stably reached " at town sewage
Reason factory pollutant emission standard " one-level emission standard A (hereinafter referred to as one-level A standard) in (GB18918-2002), along with sensitivity
The raising to sewage drainage standard of water body and the demand of Treated sewage reusing, the discharge standard of sewage improves constantly, recent Beijing
And some areas, Jiangsu have started to explore water outlet and perform grass root's four class water quality standard, the discharge standard of nitrogen phosphorus will be more harsh,
Therefore the research and development of high-efficient denitrification and dephosphorization system the most just become the most important thing of solution problem.
Summary of the invention
The best, the fluctuation of service and more harsh for existing villages and small towns sewerage integrated sewage disposal Nitrogen/Phosphorus Removal
The problem such as nitrogen discharge and phosphorus discharge standard, it is an object of the invention to build the villages and small towns sewage water treatment method of a kind of new and effective denitrogenation dephosphorizing
And device, it is mainly used in the domestic sewage of villages and small towns that effluent quality requirement is high, is especially suitable for the sensitive water body such as water head site, scenic spot
Region or need the villages and small towns sewage disposal of reuse.
The present invention includes sludge-tank (8) and the Prepositive denitrification pond (1) being linked in sequence, anaerobic pond (2), Aerobic Pond 1 pond
(3), the double clear water reserviors (7) of anoxic pond (4), Aerobic Pond 2 pond (5), MBR pond (6) and sterilization.
For achieving the above object, the present invention adopts the following technical scheme that, specifically includes following steps:
1), villages and small towns sewage be divided into two parts, 70% enter Prepositive denitrification pond (1), for Prepositive denitrification provide carbon source, water inlet with
The mud mixing refluxed in MBR pond (6), removes the nitrate nitrogen of 40-60%, creates favourable bar for follow-up anaerobic pond (2) dephosphorization
Part, Prepositive denitrification pond (1) time of staying is 1 hour；30% intakes into anoxic pond (4), provides carbon source for further denitrification,
Remove nitrate nitrogen further.
2), after Prepositive denitrification processes, sewage enters anaerobic pond (2), carries out anaerobic phosphorus release reaction, goes for aerobic stage
Except total phosphorus creates favorable conditions, anaerobic pond (2) is placed elastic filler (17) and can strengthen as carrier, increase elastic filler (17)
Removal to phosphorus, anaerobic pond (2) time of staying is 1 hour, forms A/O method with Aerobic Pond 1 pond (3) subsequently and processes technique, from
And reach the purpose of biological phosphate-eliminating.
3), sewage after anaerobic pond (2), enter Aerobic Pond 1 pond (3), Aerobic Pond 1 pond (3) placed elastic filler
(17), sewage is constantly mixed by aeration in pond, fully contacts with the biomembrane on filler, reaches Organic substance and degrade rapidly
Effect, carry out aerobic phosphorus absorption simultaneously, total phosphorus carried out certain removal, sewage is 2-in the response time in Aerobic Pond 1 pond (3)
3 hours；Aerobic Pond 1 pond (3), also dependent on influent quality and field condition not aeration, becomes anoxic pond and runs.
4), sewage behind Aerobic Pond 1 pond (3), enter anoxic pond (4), anoxic pond (4) is that denitrogenation processing is arranged, simultaneously
30% water inlet exists with the part mixed liquor refluxed, the nitrification liquid refluxed through sewage and Aerobic Pond 2 pond (5) in Aerobic Pond 1 pond (3)
Hybrid reaction in anoxic pond (4), in sewage, the pollutant of bio-degradable hydrolyze, the Organic substance in former water of degrading, simultaneously
Make full use of the Organic substance in 30% former water as denitrifying carbon source, anti-nitration reaction fully occurs, remove total nitrogen, after minimizing
The load of section operation, places the elastic filler (17) carrier as denitrifying bacteria in anoxic pond (4), filler is to nitrogen, phosphorus, removal
Effective, the time of staying is 2 hours, forms A/O method with Aerobic Pond 2 pond (5) in subsequent technique and processes technique, thus reaches de-
The purpose of nitrogen.
5), sewage enters Aerobic Pond 2 pond (5), the 6-8 hour time of staying, Aerobic Pond 2 pond (5) peace after anoxic pond (4)
Dress Ball-type packing (16), cuts bubble by the sponge filler in Ball-type packing (16), improves oxygen transmission efficiency, retains a large amount of outstanding
Floating microorganism, makes to be prone on filler hang biomembrane, and the growth that energy is stable, a large amount of degradation of organic substances, and by ammonium oxidation is
Nitrate nitrogen, simultaneously aerobic phosphorus absorption；Aerobic Pond 2 pond (5) effectively sludge concentration can reach 5000-6000mg/L.
6), sewage behind Aerobic Pond 2 pond (5), enter MBR pond (6), in MBR pond (6), MBR membrane module (10) is immersion
Hollow-fibre membrane, topmost function is to retain mud.The condition of negative pressure that MBR pond (6) membrane bioreactor produces in suction pump
