A kind of processing method of L-Arginine fermented waste fluid
Technical field
The invention belongs to Amino Acid Fermentation Wastewater processing technology field is and in particular to a kind of place of L-Arginine fermented waste fluid
Reason method.
Background technology
Arginine(Arginine, Arg)Chemical scientific name:(S)-2-Amino-5-guanidinopentanoic acid, is a kind of aliphatic alkalescence
Polarity alpha amino acid containing guanidine radicals, positively charged in physiological conditions;L-Arginine is the coding amino in protein synthesis
Acid.For mammal, arginine is classified as the half necessary or necessary aminoacid of conditionality, depend on biology stage of development and
Depending on health status, natural product are present in protamine in a large number, also for the basic composition of various protein.
L-Arginine is described as " magical molecule " by scientist, and it is one of basic amino acid, for healthy adult,
For nonessential amino acid, but arginine is to maintain the requisite aminoacid of infant growth;In ornithine cycle
Between metabolite, ammonia can be promoted to be transformed into carbamide, thus reducing Blood Ammonia Concentration, when body development is not yet ripe or body stress bar
Under part, such as lack arginine, body just can not complete physiological function;Patient lacks arginine and blood ammonia can be caused too high or even confused
Fan, baby lacks arginine and is then unable to normal development and growth.Admit the doctor of L-Arginine from Nobel Prize in medicine in 1998
After learning effect, L-Arginine causes the mad interest in medical drug field, and Columbia Univ USA was once likened to the heart
" the magical bullet " of vascular system;The discovery of L-Arginine makes heart disease, immunologic function, obesity, gene growth shortage, high blood
The treatment of symptom that pressure, sexuality go down and the mankind are aging etc. obtains very big improvement.
With the fast development of aminoacid industry in recent years, the demand of aminoacid is surged, it is maximum that China has become the whole world
Amino acids production state.In amino acids production, contain higher ammonia nitrogen due in the high-concentration waste water of flushing membrane worry equipment, such as
What denitrogenation is its key problem, to the process of this waste water currently without preferable method.Chinese patent CN104222704A and
CN104261947A is prepared for feedstuff and fertilizer etc. with fermentation waste water respectively, and said method design is unique, is suitable for possessing fertilizer
Or the enterprise of Feed Manufacturing qualification and ability.
Traditional denitrification process usually by anoxic zone and aerobic distinguish, such as Prepositive denitrification, rear-mounted denitrification, A/O method,
A2O method, SBR etc., but because nitrobacteria growth speed is slower, limit the raising of nitric efficiency, bacteria adhension poor reliability
And carbon source fails the shortcomings of not enough to promote during denitrification.Meanwhile, the process of nitrification and denitrification also more difficult control, and traditional
Technique also exist that capital expenditure is big, operating cost is high, a series of drawback such as energy dissipation and emission greenhouse gas.But good
The progress of oxygen denitrifying bacterium, the discovery of nitrification bacteria and aerobic denitrification, heterotrophic nitrification and autotrophic denitrification is simultaneously
Nitrification and denitrification has established theoretical basiss.Orientation structure can carry out biochemistry/nitrification/denitrification in same reaction unit simultaneously
The high effective microbial community of effect, adapts to fermentation high concentration including screening and enrichment and produces waste water, has the spy of degraded advantage
Effect aerobic denitrifying bacteria, reaches the microcirculation of forming material mutually utilization between whole microorganism fungus kind, allows COD as life
In change/nitrification/anti-nitration reaction must being utilized of carbon source, improve the biological efficiency of sewage disposal comprehensively.Therefore in aerobic bar
Carry out simultaneous nitrification-denitrification under part(SND)Technology become current biological denitrificaion and open new technology.
Biotechnology processes fermentation waste water, and it possesses with low cost, the advantages of do not result in secondary pollution, but exists micro-
Biocompatibility is unreasonable, and treatment effeciency is low, and microbe carrier to there is internal mass transfer poor, be difficult printing opacity, specific surface area is little,
The defect such as service life is short;Biological preparation needs to throw in often, increased cost, and injected volume is big, the mud of generation
Amount is greatly it is not easy to process.
Content of the invention
The purpose of the present invention is the deficiency for traditional handicraft, there is provided a kind of process side of L-Arginine fermented waste fluid
