Description
Technical field
The invention belongs to field of environment engineering more particularly to the biological denitrification process and dress of high ammonia nitrogen, low ratio of carbon to ammonium waste water
It sets.
Background technique
The anaerobic digestion of the excess sludge of urban wastewater treatment firm is the effective of current cities and towns excess sludge stabilization processes
Measure, the technology have the advantages that recycle the energy, wastes reduction and innoxious.In anaerobic digestion process, anaerobic bacteria is decomposed
Organic matter in sludge generates methane gas, as energy recovery.Meanwhile the deamination of microorganism can release nitrogen
(mainly based on ammonia nitrogen and a small amount of organic nitrogen).After dehydration, the nitrogen overwhelming majority can remain in sludge-digestion liquid, so
Nitrogen content in digestive juice is very high (500-2000mg/L).Sludge-digestion liquid shows the characteristics of high ammonia nitrogen, low C/N, existing
Sewage treatment plant be difficult effectively to handle it.In recent years, domestic and international researcher proposed at sludge-digestion liquid side
Then reason technology discharges it into sewage that is, using most nitrogen in Process of Biological Nitrogen Removal removal sludge-digestion liquid again
Treatment plant is handled together with sanitary sewage.The research of side processing technique and application to high ammonia nitrogen, low ratio of carbon to ammonium waste water it is effective
Processing is of great significance.
Nitrosation technology has the advantages that low energy consumption, operating cost is small compared with the technology of nitrification.Sludge-digestion liquid temperature is high,
The ratio of ammonia nitrogen and basicity is suitable, is easier to realize stable nitrosation process by controlling service condition, is anaerobism ammonia oxygen
Chemical industry skill provides suitable water inlet.For Anammox technology compared with nitrification-denitrification technology, it does not need additional organic carbon
Source does not need to add medicament, saves a large amount of operating cost, avoid secondary pollution without aeration.Therefore, nitrosation and
Anammox technology is the used technical way of current sludge-digestion liquid side processing.Anaerobic ammonium oxidizing bacteria vulnerable to
The problems such as environment influences and the sludge doubling time is long greatly limits the extensive use of this technology.Especially handle
When actual waste water, water quality is complicated and water fluctuates the starting speed and bacterial activity that can all influence anaerobic ammonia oxidation reactor.Cause
This, nitrosation at present and Anammox technology are faced using challenge.
Summary of the invention
To make up prior art deficiency, it is an object of the present invention to provide it is a kind of efficiently, low-cost processes sludge-digestion liquid be
System and technique, the present invention can realize the quick start and subsequent stable operation of anaerobic ammonia oxidation reactor simultaneously, and improve and detest
Application range of the anaerobic ammonium oxidation technology in actual waste water denitrogenation field.Low energy consumption for the process operation, removal efficiency is high, secondary pollution
It is small.
Inventive concept of the invention is: sludge-digestion liquid initially enters coagulative precipitation tank, is flocculated by adding medicament
Reaction；Then, the water outlet after primary sedimentation tank removes oil removal enters biological denitrificaion unit.The core of biological denitrificaion unit is SNAD
(while nitrosation, Anammox and denitrification)-MBBR (moving bed biofilm reactor), it is remaining in sludge-digestion liquid to have
Machine carbon source and most nitrogen are effectively removed in the segment process；Finally, sludge-digestion liquid row after treatment
Enter sewage treatment plant.Technique initial stage, sludge-digestion liquid enter biological denitrificaion unit after diluting, with the raising of removal rate, gradually
Reduce sludge-digestion liquid extension rate, improves water inlet total nitrogen load.In SNAD-MBBR unit, nitrite bacteria utilizes oxygen
By water part NH4 +- N is converted into NO2 -- N, then ANAMMOX bacterium is by the NO of generation2 -- N and residue NH4 +- N is converted into N2, real
Now to the removal of nitrogen most of in waste water.Denitrifying bacteria is using the COD in waste water as electron donor, in anaerobism or anoxic item
Under part, by the NO of generation3 -- N and remaining NO2 -- N is reduced into N2, realize further denitrogenation.Inside SNAD-MBBR unit
Biomembrane can be formed on biologic packing material, reduce sludge loss.Meanwhile the spatial distribution of biomembrane is anaerobic and aerobic on filler
Bacterium provides advantageous life condition, realizes denitrogenation and removes the COD in waste water.
Primary and foremost purpose of the present invention is the sludge digestion liquid treating system being claimed using SNAD-MBBR as core technology, should
System includes sequentially connected coagulative precipitation tank, primary sedimentation tank, SNAD-MBBR unit and secondary settling tank, and the coagulative precipitation tank is built-in
There is blender, mud scraper is equipped in primary sedimentation tank, the water after precipitating carries out removal of carbon and nitrogen in SNAD-MBBR unit.
Sump is additionally provided in above system, sump A is connect with primary sedimentation tank, the water overflow after making precipitating to sump A.
Sump B is connect with secondary settling tank.
Be additionally provided with inclined-plate clarifying basin in above system, the inclined-plate clarifying basin can be used this field it is any can play it is heavy
Form sediment, separate, going the sedimentation basin of oil removal function.
Above-mentioned SNAD-MBBR unit is circle or rectangular, preferably rectangular.PH is equipped with inside SNAD-MBBR unit to pop one's head in
And blender, the blender are vertical stirrer, are located at SNAD-MBBR unit middle position, biologic packing material is suspended in SNAD-
Inside MBBR unit.
The treatment process are as follows: sludge-digestion liquid enters coagulative precipitation tank by water pump, and coagulative precipitation tank center is equipped with stirring
Device carries out flocculation reaction by dosing pump dosing coagulant thereto.Coagulative precipitation tank is discharged overflow to primary sedimentation tank, goes out after precipitating
Water overflow to sump A, primary sedimentation tank periodically carries out spoil disposal.Then boosted pump, which is mentioned by sump A to SNAD-MBBR unit, carries out
Removal of carbon and nitrogen is finally discharged and is discharged into sewage treatment plant through secondary settling tank.
Preferably, aeration quantity being adjusted according to inflow, the DO concentration controlled in SNAD-MBBR unit is no more than 0.8mg/L,
