Description
Technical field
The present invention relates to a kind of methods of anerobic sowage ammoxidation coupling solid phase denitrification efficient denitrification, belong to sewage treatment
Field.
Background technique
It is high with nitric efficiency, dirty that Anammox (Anammox) technology is compared to traditional nitration denitrification technology
The advantages that mud yield is few and is not necessarily to additional carbon, has broad popularization and application prospect.But anaerobic ammonia oxidizing bacteria belongs to autotrophy
Bacterium, growth rate are slow, the doubling time is long, while Anammox can only remove 80%-90% and be deposited in the form of ammonia and nitrous acid
Nitrogen, still having the nitrogen of 10%-20% to be converted into nitrate nitrogen cannot be removed.Therefore, it is reacted using single Anammox
Denitrification effect is ideal not to the utmost.In recent years, many researchs confirm, anaerobic ammonia oxidizing bacteria and denitrifying bacterium can coexist in same reactor
In and form certain synergistic effect, this is realizes that Anammox coupling denitrification provides foundation in sewage water denitrification processing.
In Anammox and denitrification coupled system, denitrification process needs external carbon source as electron donor, often
The denitrification additional carbon used is the traditional dissolved organic carbon source such as glucose, methanol, ethyl alcohol, acetic acid.Traditional organic carbon
Although source has the advantages that denitrification utilization rate is high, denitrification effect is good, carbon source transport is higher with operating cost, and can be right
Anaerobic ammonia oxidizing bacteria activity generates potential threaten.
Based on the advantage of engineering reliability and economy etc., rich cellulose-containing natural material (straw, straw, jade
The cellulose families such as meter Xin, sawdust organic carbon source) it is increasingly becoming the research hotspot of novel denitrifying carbon source.Currently, many researchs
The result shows that preferable denitrification denitrogenation effect can be obtained using rich cellulose-containing agricultural stalk as denitrification additional carbon
Fruit.Therefore, solid carbon source is added in Anammox denitrification process, can not only be provided for all kinds of microorganisms growing carrier and
Stable metabolism environment, and energy promotion system removes the denitrification of nitrate, reduces nitrate nitrogen and brings to receiving water body
Harm.
Currently, not yet using agricultural stalk as the specific method of solid denitrifying carbon source coupling Anammox.
Summary of the invention
The present invention is intended to provide a kind of method of anerobic sowage ammoxidation coupling solid phase denitrification efficient denitrification, with agriculture straw
Stalk is added in anaerobic ammonia oxidation process as solid-phase carbon source and biofilm carrier, by Anammox and solid phase denitrification coupling
It closes, realizes more preferable, more stable denitrification effect.
The method of anerobic sowage ammoxidation coupling solid phase denitrification efficient denitrification of the present invention, includes the following steps:
Step 1: the dry cellulose-containing solid-phase carbon source of richness being crushed to pulverizer having a size of 1-200mm, is then soaked
Enter in water or matrix solution and impregnates 1-2 weeks；Since cellulose family solid-phase carbon source releases the COD meeting that carbon amounts is larger, largely discharges early period
Certain percussion is generated to reaction system, therefore broken solid-phase carbon source can first impregnate 1-2 before being added to reactor
Week, so that solid-phase carbon source is released carbon and stablized.
Step 2: the stable solid-phase carbon source of carbon will be released after immersion to be added into anaerobic ammonia oxidation reactor, dosage and water inlet
Nitrogen concentration is positively correlated, and controls the service condition of reactor, makes Anammox is synchronous with solid phase denitrification to carry out.
In step 1, the solid-phase carbon source is agricultural stalk, and the agricultural stalk refers to rich cellulose-containing natural material,
Mixing selected from one or more of straw, straw, rice husk, corncob, corn stover, leaf or sawdust etc..
In step 1, the pH value of the matrix solution is 7.0-8.0, and matrix solution includes following components (L-1): 2.5g
KH2PO4, 125g KHCO3, 75g MgSO4·7H2O, 1.6g CaCl2·2H2O；1.0ml microelement I and microelement II；
It include (L in microelement I-1): 5g EDTA, 18g FeSO4·7H2O；It include (L in microelement II-1): 15g EDTA,
0.43g ZnSO4·7H2O, 0.25g CuSO4·5H2O, 0.19g NiCl6H2O, 0.24g CoCl6H2O, 0.014g
H3BO4, 0.99g MnCl2·4H2O, 0.22g NaMoO4·2H2O, 0.21g NaSeO4·10H2O。
In step 2, solid-phase carbon source after immersion can be added after anaerobic ammonia oxidation reactor starting, can also be with
It is added before anaerobic ammonia oxidation reactor starting.
In step 2, the ratio of COD total amount and total nitrogen concentration in water inlet that the solid-phase carbon source added discharges daily is set as
0.1-4.0:1, the solid added needed for being calculated according to the ratio (COD/TN) of the COD and total nitrogen of the concentration of water inlet total nitrogen and setting
The amount of carbon source.
In step 2, reactor service condition is set as temperature control at 20-35 DEG C, pH 7.0-8.5, and dissolved oxygen is
0.00-0.05mg/L, hydraulic detention time 0.1-3d, inoculation anaerobic ammonium oxidation sludge concentration are 0.5-5.0gVSS/L.
In the present invention, the mix and match of agricultural stalk is according to influent quality condition, in conjunction with the releaser of different agricultural stalks
The difference of matter type and rate optimizes collocation, to carry out beneficial complement and promotion to sewage water denitrification process.The present invention
Anammox is coupled using agricultural stalk as denitrifying carbon source and biofilm carrier, has reached efficient coupling denitrification effect.
Compared with prior art, the beneficial effects of the present invention are embodied in:
1, since Anammox reaction is the sour process of a consumption, the pH of system be will increase during the reaction, therefore be
System needs additional acid to maintain the pH of reactor.And agricultural stalk is as denitrifying carbon source and biofilm carrier, in systems
The substances such as humic acid, which can be generated, reduces the pH of system, therefore the present invention couples Anammox using agricultural stalk solid phase denitrification
Method can maintain the pH in reaction system, eliminate the link of single Anammox reaction acid adding, both reduce and be processed into
This alleviates processing work again.
2, single Anammox reaction system theoretical maximum removal rate is 89%, there is 10%- during the reaction
20% nitrogen is converted into nitrate nitrogen and cannot be removed.Single solid phase denitrification is carried out for the nitre of low concentration using agricultural stalk
Hydrochlorate nitrogen has preferable removal effect, but in addition to needing to add a large amount of agricultural stalk conduct when processing high concentration nitrate nitrogen
Outside solid carbon source, the later period is difficult to meet the removal of high concentration nitrate nitrogen with the decline for releasing carbon ability.Therefore the present invention is by solid phase
Denitrification is coupled with Anammox, the NO for the 10%-20% that Anammox generates in coupling process3 -- N can be
Solid phase denitrification provides electron acceptor, can remove this part NO by solid phase denitrification3 --N.The two coexists, can be in certain journey
The defect that denitrification and Anammox reaction are made up on degree reaches better denitrification effect and lower processing cost, and logical
Overcoupling acts on the concentration for reducing effluent nitrate-nitrogen, reduces nitrate nitrogen and endangers receiving water body bring.
3, the present invention couples Anammox using agricultural stalk as denitrifying carbon source, with traditional dissolved organic carbon source
It compares, agricultural stalk has that low in cost, source is sufficient, and the advantages of slow releasing organics, can guarantee denitrification process
It is lasting to carry out.It can also play the role of providing growing carrier for microorganism simultaneously, be the bacterium such as anaerobic ammonia oxidizing bacteria and denitrifying bacterium
Group creates a more stable living environment, has extensive development and application prospect.
