Description
Technical field
The invention belongs to biological denitrification reactor field, and in particular to a kind of step integration denitrification reactor.
Background technology
Short distance nitration-anaerobic ammoxidation technology is to be currently known most economical bio-denitrification technology, is a kind of sustainable development
The sewage disposal technology of exhibition.Reaction principle is following (consideration Microbe synthesis)：
Short distance nitration：
Short distance nitration bacterium (AOB) generation cycle is about 0.53d, aoxidizes 1mg NH4 +For NO2 -Cell yield is 0.15mg, good
Oxygen amount 3.16mg.
Anammox：
Anaerobic ammonia oxidizing bacteria (AAOB) generation cycle is about 11d, reacts 1mg NH4 +For N2Cell yield is 0.11mg.
Short-cut nitrification technology is only needed in raw water about 1/2 NH4 +- N is oxidized to NO2 -- N, is greatly reduced aeration
Amount；Anaerobic ammonia oxidizing bacteria low yield (0.11mg/mgNH4 +- N), sludge yield is low, has saved the expense of specific resistance to filtration.
Due to requirement of the anaerobic ammonia oxidizing bacteria to growth conditions it is very harsh, and generation cycle length, low yield, enrichment culture
Difficulty, the matrix of reaction is also simultaneously mortifier.Therefore, short distance nitration is combined with Anammox has in a reactor
Convert when producing beneficial to matrix, it is to avoid suppression of the free nitrous acid of sub- nitrogen accumulation generation to anaerobic ammonia oxidizing bacteria.
Existing biological denitrification reactor has：Application number：201210289959.2, denomination of invention：Integrated cage denitrogenation
Reactor, a kind of integrated cage denitrification reactor of the disclosure of the invention.Reactor body sets successively from top to bottom inhalant region, anti-
Area and gas collection area, inhalant region is answered to set discharge pipeline, flow direction-changing area, water inlet pipe and air inlet pipe, air inlet pipe upper end successively from top to bottom
If aeration head；Reaction zone sets midfeather and is divided into aerobic zone and anaerobic zone, is divided into three cages, cage by four pieces of perforated retainers respectively
1/4～1/3 sinking/floating porous aggregate of interior filling；Gas collection area sets midfeather and is divided into settling zone and outgassing area, and by upper water conservancy diversion
Plate and chin spoiler insertion, settling zone top sets downflow weir, and isopipe root sets out water pipe.Short distance nitration and anaerobism are melted in the invention
Ammoxidation can avoid the bio-toxicity caused by nitrite accumulation in one, can also overcome matrix ratios to regulate and control a difficult problem；Function bacterium
Spatial distribution be relatively fixed, be conducive to the optimization of micro-ecological environment；Under the driving of ascending air, reactant liquor interior circulation, nitre
Change with denitrogenation alternately, contribute to mass transfer and reaction, improve volume denitrification efficiency.But the invention is disadvantageous in that：
(1) when influent ammonium concentration is relatively low, aeration rate must be adjusted so as to it is less, interior circulation driving force deficiency will affect pass
Matter and the carrying out of reaction.If aeration rate is not turned down, aerobic zone dissolved oxygen (DO) will be caused too high so that NOB
(NOB) a large amount of numerous, NOB is by NO2 -- N is oxidized to NO3 -- N, the anaerobic ammonia oxidizing bacteria (AAOB) for causing anaerobic zone lacks substrate
NO2 -- N, then Anammox cannot carry out, system crash.
(2) when muddy water mixed solution is recycled to anaerobic zone, sludge is easily retained that (and AOB is in anaerobic zone by anaerobic zone filler
Due to without dissolved oxygen, it is difficult to survive, can be gradually dead), it is difficult to return aerobic zone participate in short distance nitration thus reactor hold
Product efficiency is relatively low.This phenomenon can cause the sludge in muddy water mixed solution constantly to be retained by anaerobic zone filler when just starting, its
In AOB it is gradually dead, sludge quantity is fewer and feweri, in the case of equal aeration rate, dissolved oxygen more and more higher, the dissolving of anaerobic zone
Oxygen is also stepped up, final whole system collapse.
(3) aerogenesis disturbs precipitation water outlet, causes the sludge loss comprising anaerobic ammonia oxidizing bacteria (AAOB), water outlet to be hanged
Float concentration is higher.
(4) when influent ammonium concentration is higher, water outlet total nitrogen concentration easily fluctuates therewith, cause water outlet total nitrogen concentration compared with
Height, effluent quality is deteriorated.
(5) water outlet NO2 -- N concentration is higher, due to NO2 -- N is " three cause " material, generally requires follow-up facility to water outlet again
Process, to eliminate NO2 -The pollution of-N.The waste water of the invention is through aerobic zone, NH4 +- N is oxidized to NO2 -- N, but part muddy water is mixed
Compound carries out upwards immediately mud-water separation, and supernatant Jing downflow weirs, outlet pipe are discharged, now this part mud mixture not yet Jing
Anammox area is crossed, the NO in mud mixture2 -- N and NH4 +- N fails to be converted in the presence of AAOB nitrogen with regard to outer row,
Therefore NO in water outlet2 -- N concentration is higher.
Apart from the above, also there is the suppression for being difficult to avoid that dissolved oxygen to anaerobic ammonia oxidizing bacteria in existing equipment.Many institutes
Known, in the presence of having dissolved oxygen (DO), AAOB is idle, and the mineralized nitrogen in reactor is by the AOB for now working
Sub- nitrogen, the sub- nitrogen of generation cannot be converted in time, when concentration reaches certain numerical value, can produce the suppression of matrix to AAOB again,
It is likely to result in the collapse of reactor.Such as：Utility model patent《The low C/N of integrated batch (-type) is more biological than Anammox
Denitrogenation reactor》There is this phenomenon in (Authorization Notice No. CN203200141U), the reactor belongs to complete when running
The state of mixing.The reactor certainly will be caused in aeration process using intermittent aerating and the operational mode of stirring, and AAOB cannot
Work, and after aeration terminates, AAOB will just start working in the case that in the reactor DO is depleted, substantially prolongs anti-
Between seasonable, the capacity utilization of reactor is reduced, while easily causing suppression of the matrix to AAOB.

Compared with prior art, beneficial effects of the present invention are：
1st, the present invention is able to ensure that suppression of the prolonged free ammonia of high concentration to NOB so that short distance nitration is relatively reliable.
After each draining of the invention terminates, it is desirable to intake immediately to predetermined water level；When reactor does not run in leaving unused, water inlet is also required
Leave unused again to predetermined water level.Enter every time after water, the concentration of free ammonia is highest in whole course of reaction, can so keep trip
From suppression of the ammonia to NOB (NOB) so as to be more difficult to amount reproduction in the reactor, it is ensured that short distance nitration can
Lean on.Reason is：Ammonia oxidation bacteria (AOB) and anaerobic ammonia oxidizing bacteria (AAOB) can more stand trip than NOB (NOB)
From the suppression of ammonia.According to documents and materials introduction：Free ammonia (FA) is 10mg/L～150mg/L to the inhibition concentration scope of AOB, right
The inhibition concentration scope of NOB is 0.1mg/L～1.0mg/L, is 20mg/L～25mg/L to the inhibition concentration scope of AAOB.
2nd, present invention reduces " three cause " material NO2 -The discharge capacity of-N, water outlet concentration of suspension is relatively low.When the ammonia in waste water
When nitrogen will be depleted, the reading of online dissolved oxygen tester is persistently raised, and now closes air inlet valve, standard-sized sheet aeration
Gas inlet valve, with aeration exhaust gas driven 1～30min of interior circulation, no longer oxygenation so that NO2 -- N reacts complete as far as possible, water outlet
NO2 -- N concentration is low.And during with aeration exhaust gas driven interior circulation, the short distance nitration of aerobic zone is due to anoxic, ammoxidation
Bacterium (AOB) can not again by NH4 +- N is oxidized to NO2 -- N, and the anaerobic ammonia oxidizing bacteria (AAOB) of anaerobic zone will work to matrix NH4 +- N or NO2 -One of-N's exhausts.So follow-up quiescent setting process, will not again there is aerogenesis interference precipitation, thus go out
Aqueous suspension concentration is relatively low.
3rd, the present invention is more energy efficient, and volume efficiency is high.The distribution device of the optional differing heights of the present invention carries out aeration, not only
Can with the change of flexible adaptation influent load, save energy consumption, it is critical only that can also adjust the length of anaerobic zone and aerobic zone and
Dischargeable capacity, the controllability of reactor is higher.When short distance nitration speed is low or influent concentration is relatively low, it is not necessary to so much oxygen
When, can select the oxygenation distribution device of high height carries out aeration, because now the depth of water residing for oxygenation distribution device is shallower, because
And Fan Energy-saving, and oxygen transfer efficiency is relatively low.When aeration is carried out using highest oxygenation distribution device, in oxygenation distribution device
Following adjustable area is completely reformed into anaerobic zone, and now anaerobic zone is most long, dischargeable capacity is maximum；And aerobic zone is most short, effectively hold
Product is minimum.Such case is applied to the reactor start-up initial stage, ammonia oxidation bacteria (AOB) is compared due to anaerobic ammonia oxidizing bacteria (AAOB) and
Say, its generation cycle length, low yield, enrichment culture are difficult, therefore give the more living spaces of anaerobic ammonia oxidizing bacteria and be conducive to
Its growth.After reactor is successfully started up, can gradually adopt the oxygenation distribution device of lower position carries out aeration.Because now
Anaerobic ammonia oxidizing bacteria (AAOB) amount is larger and part success apposition growth is on the filler of anaerobic zone.Now increase
The length and dischargeable capacity in oxygen area, can provide more matrix NO2 -- N, improves the volume efficiency of reactor.
4th, the present invention rationally make use of the waste gas of aerobic zone (mainly the waste gas of aeration, additionally comprise the anaerobism in adjustable area
Ammoxidation aerogenesis).The remainder of exhaust gas after the aeration of aerobic zone is collected in the present invention, is reused, reduce oxygenation blower fan
The oxygen in gas is blasted containing rate, the not only control beneficial to the LDO of aerobic zone is required, and beneficial to reinforcing inner recirculation flow
Speed, there is provided sufficient interior circulation driving force.For the reasonable utilization of aerobic zone remainder of exhaust gas.Remainder of exhaust gas participates in again aerobic
In the aerated reaction in area.It is the 40% of traditional nitration reaction because short distance nitration is not very high to the demand of oxygen, therefore aeration
Amount certainly will be too big, and when motive force and uniform mixing equipment by the use of aeration as reactor, too low aeration rate may not
System is sufficient for stirring the requirement of dynamics, the waste gas " being previously used " after dissolved oxygen is now mixed into, then carries out aeration
Air in oxygen content obtain a certain degree of reduction, for system maintains relatively low dissolved oxygen levels (0.01～0.5mg/
) and interior circulation driving force is all favourable L.
5th, the present invention can maintain the biomass of AOB in reactor so that aerobic zone maintains relatively low dissolved oxygen levels (0.01
～0.5mg/L), it is ensured that NOB will not become dominant bacteria.The present invention rationally make use of the nitrogen of anaerobic zone.The anaerobism of left half-court
Area can be by by the filler of anaerobic zone institute using aerogenesis circulating fan intermission aeration (such as 10 minutes once, each aeration 10 seconds)
Retention AOB bacterial classifications split away off under the concussion effect of ascending air, return to aerobic zone and continue to participate in ammoxidation circular response；Separately
The ascending air of the intermission aeration of outer aerogenesis circulating fan may also help in and adhering to the AAOB bacterium that tiny bubble floats to collection chamber
Removing tiny bubble is planted, is come back to and participate among liquid phase reaction.
6th, displacement of the invention is adjusted according to the ammonia nitrogen concentration of water inlet raw water, temperature, PH, typically intaking to pre-
Determining the concentration of free ammonia in water level post-reactor mixed liquor does not suppress anaerobic ammonia oxidizing bacteria to be limited.
7th, the present invention using batch (-type) interior circulation operational mode, one is that the side conversion lateral dominance for realizing sub- nitrogen is used, two be by
Short distance nitration reacts to be carried out simultaneously with Anammox reaction subregion.
8th, Ball-type packing of the invention contributes to the growth of AAOB bacterial classifications.The little iron block of filler inside placement of anaerobic zone, one
It is to play a part of to adjust packing density, the state for keeping sinking of the filler in water motionless is so unlikely to so that being attached to
Biomembrane on filler comes off because of effects such as collision, frictions, protects AAOB bacterial classifications.And in the case of working as aeration, filler quilt
Hold up, whole packed bed is in suspension swelling state, now continuous collision friction between filling ball and filling ball, biomembrane takes off
Fall, the little iron block of ball interior also continuous downthrust sponge carrier can aid in the biofilm detachment on sponge carrier.Two
Little iron block gets rusty easily and is oxidized corrosion, and ferrous ion is element necessary to Anammox bacteria growing, and little iron block is to detest
Anaerobic ammonium oxidation bacterium (AAOB) provides ferrous element cheap and easy to get, supplies nearby, contributes to the growth of AAOB.
