Description
Technical field
It is more particularly to a kind of to be suitable at soy sauce brewing wastewater the present invention relates to high concentrated organic wastewater integrated approach technology
The modularization integrated approach of reason.
Background technology
At present, the soy sauce of China is produced based on " low salt solid process " and southern " high-salt dilute technique " in the north.
General soy sauce production process drenches the process such as oil and heating preparation including Feedstock treating, koji-making, fermentation, leaching, and soy sauce is useless
Water is a kind of higher food fermentation waste water of content of organics, its composition be mainly grain residue (such as：Broken beans bits, wheat bran, face
Powder, sugar, soy sauce, fermentation residue, the enzyme and metabolite of various microorganisms and microorganism secretion, soy sauce pigment, micro washing
Agent, disinfectant and a small amount of salinity etc.), colourity is higher, complicated component, therefore wastewater treatment has certain difficulty.
The difficult point of sauce waste water processing has：
(1) colourity is high.Soy sauce pigment is the part for being most difficult in sauce waste water remove, and soy sauce pigment is main by two parts group
Into：One is because sugared ammonia reacts the black of (Maillard reaction) formation during sauce fermentation；Secondly because during product preparing
The caramel colorant manually added.Above-mentioned two classes material is the extremely complex high-molecular compound of structure, up to the present, not yet
Understand its molecular structure.Its chromophore contained is conjugated the base that adds lustre to by following two or two or more and constituted, these conjugation lifes
Color base makes organic molecule produce absworption peak in visible region, waste water is provided with colourity.Experience have shown that, activated carbon adsorption tank,
Removal of the methods such as light electrolysis to this kind of chroma in waste water is unsatisfactory, and colourity has the trend of intensification during oxygenation stripping.
The removal of coloring matter is the difficult point in sauce waste water processing in waste water, so far, rarely has the report for reaching first discharge standard
Road.
(2) salinity is high：Salt is one of primary raw material of soy sauce production, soy sauce tank flushing water, filter cloth in sauce waste water
Flushing water etc. is high-salt sewage, and salt content is 1~5% (about 10000~50000mg/L).Although producing waste water and soy sauce seasoning
Other common sewage of material factory can reduce salt content after mixing well, but salt content is in higher level.Salinity is to materializing strategy
The influence very little of technique, but have corrosiveness to institute's contacting metal equipment, the service life of equipment will be shortened.In addition, high salinity
There is large effect to biochemical processing process.
(3) impact load changes greatly.Sauce waste water water quality seasonal variety is another difficult point of wastewater treatment process, greatly
Most soy sauce factory koji-making season Relatively centralizeds, the soy sauce factory for shining technique especially with dew is even more so.Koji-making waste water gives up with other
Aqueous nature is different, during koji-making, can produce the foam material waste water of very high concentrations, its COD is up to 20000mg/L or so, useless to soy sauce
Water process causes very big difficulty.The mode of production that factory fixes output quota by sales, causes waste water quality fluctuation very big, impact load change
It is larger, meanwhile, it is greatly affected the normal operation of biological treatment facility.
(4) pollutant component is unstable.Some soy sauce brewing manufacture product categories are complicated, generally include light soy sauce, old
Take out soy sauce, red vinegar, thick chilli sauce, chilli garlic sauce, vinegar, oil consumption, fermented bean curd etc. and brewage product, this makes waste component more complicated, administer more
It is difficult.
