Description

The technique of industry COD and ammonia nitrogen in a kind of removal gourmet powder waste water
Technical field
The present invention relates to a kind of processing method of waste water, particularly provide in a kind of removal gourmet powder waste water industry COD and The technique of ammonia nitrogen.
Background technology
With the economic continuous progress developed rapidly with technology, China has become the production and consumption big country of monosodium glutamate, But the wastewater flow rate discharged during glutamate production is big, mother liquor of the fermented gournet powder liquid through waiting electricity to be discharged after extracting glutamic acid has CODCr is high, BOD5 is high, thalline content is high, sulfate radical (it is chlorion to use instead before sulfuric acid adjusts pH) content is high, ammonia-nitrogen content is high and pH The characteristics of value (1.5-3.2) low " five high is low ".It is a kind of very big industrial wastewater of difficulty of governance.Due to can not effectively administer Gourmet powder waste water, many Gourmet Powder Factories are put into the row of national major polluting sources unit, and the improvement of gourmet powder waste water has become restriction taste The great difficult problem of smart manufacturing enterprise's development.
On the one hand:The extraction of the monosodium glutamate generally electricity such as use-and from the method for friendship, make glutamic acid by adding the concentrated sulfuric acid to adjust isoelectric point Crystallize out, and the ammonium sulphate waste liquor produced in production process, greatly difficulty is brought to liquid waste processing, to environment, water source Cause directly harm.
On the other hand:Monosodium glutamate industry is also the greatest contamination source in China's fermentation industry, and according to statistics, msg product per ton is produced Raw 15 tons or so of high-concentration waste water.Monosodium glutamate industry high concentrated organic wastewater is seriously polluted, is the common problem that industry is protruded.Fermentation Waste liquor or glutamate wastewater are the primary pollution source of glutamate production industry.
The a large amount of thalline contained in extracting glutamic acid waste water, it is a kind of single cell protein, right containing rich in protein The chemical composition of mycoprotein is analyzed and finds the content of protein in the discarded thalline of glutamic acid to be up to 85.8% total after drying Amino acid content is 78.77%, raw material dregs of beans, yeast commonly used higher than current protein zymolyte etc..Its amino acid classes and match somebody with somebody Than all more complete, and contain other nutriments such as abundant vitamin, nucleic acid, polysaccharide.And in glutamic acid fermentation process Added glucide can generate oligoisomaltose afterwards by fermentation together with glutamic acid.Glutamic acid fermentation produces high-concentration waste Water carries out desalting processing by carrying out bipolar membrane electrodialysis after ultrafiltration membrance filter, and the waste water after desalination can be used to produce fertilizer, Clear liquid after the desalination for obtaining contains substantial amounts of oligoisomaltose.These utilities are discharged in vain, cause substantial amounts of every year Loss and waste.
It is reported that often producing 1t monosodium glutamates, 10-15 tons of mother liquor extracted after glutamic acid of discharge is will be about, the whole nation will arrange every year Put 10,000,000 tons of this high concentrated organic wastewaters.Not only severe contamination natural environment, and constrain the development of monosodium glutamate industry. Although glutamate production enterprise, scientific research institution and relevant universities and colleges have all carried out substantial amounts of research to improvement.But, current state It is inside and outside to be all also applied to production practices without ripe complete set technology.Major problem is that one-time investment is excessive, or it is daily Operating cost is too high, and most Gourmet Powder Factories cannot bear, it has to the present situation of long-term maintenance discharge beyond standards.
Therefore, a kind of environment-protective process for processing glutamic acid fermentation waste water is studied, to reduce contaminated wastewater, turn waste into wealth, is The technical problem of this area urgent need to resolve.
The content of the invention
The purpose of the present invention is directed to the deficiency of traditional handicraft, there is provided a kind of biological agent for the treatment of gourmet powder waste water, its Production cost is significantly reduced, production process is easy to operate, stable and reliable product quality.Meet comprehensive utilization of resources, energy-conservation to subtract The requirement of row, while reducing discharging of waste liquid, alleviates sewage disposal burden, brings huge economic benefit and environmental protection is imitated Benefit.In order to realize the object of the invention, adopt the following technical scheme that:
The technique of industry COD and ammonia nitrogen, comprises the following steps in a kind of removal gourmet powder waste water:
(1)Gourmet powder waste water enters pre- anaerobic pond UASB, controls certain hydraulic detention time, and water outlet enters sedimentation basin;
(2)Sedimentation basin adds biological agent advanced treating;
(3)Excess sludge is processed, supernatant by sludge condensation, dehydration through outward transport after press filtration after biological agent treatment Outer row is carried out after clear water reserviors.
The biological agent, its raw material for including following weight portion:
Aerobic denitrifying bacteria 8-10 parts, bacillus 8-10 parts, aspergillus niger 7-9 parts, Rhodococcus sp 7-9 parts, Bacillus foecalis alkaligenes 5-8 parts, 5-8 parts, Candida albicans 3-5 parts of brick red streptomycete.
The aerobic denitrifying bacteria is aerobic denitrifying bacteria(Paracoccus pantotrophus)ATCC 35512.
