Description
Technical field
The present invention relates to the circulation comprehensive of a main laver processing waste water to utilize system and technical method, belongs to processing of farm products
The wastewater processing technology in field, fall within the discarded object integrated treatment utilization technology in processing of farm products field.
Background technology
Seaweed is the general designation of Bangiales section Porphyra marine algae, including Porphyra yezoensis, porphyra haitanensis, laver, circle seaweed,
Numerous kinds such as side seaweed, the kind cultivated extensively at present are Porphyra yezoensis, porphyra haitanensis, laver.
Laver nutritive enriches, according to the difference of growth time section, protein content per 100g dry lavers in 35-50%,
The content 25% or so of polysaccharide, fat content 3% or so, the lubricant component in seaweed is mainly polyunsaturated fatty acid.Especially
It is worth lifting, a kind of special acid --- the taurine all not contained in any land plant is also contained in seaweed,
The content of taurine is 1% or so in seaweed, and this content is even above many marine animals.
There is the platform set of laver processing machine group more than 1000 in China at present, is distributed mainly on Jiangsu, Fujian, Zhejiang, Along The Coast of Shandong Province.
Seaweed processing season concentrates on the April in December to next year.
It is often to continuously run for 24 hours to process laver processing machine in season, and seaweed processing needs substantial amounts of water, and processing is used
Water uses city tap-water, to meet drinking water standard.Every processing machine daily (24 hours) with about 100-120 cubes of water
Rice, is calculated accordingly, and the annual seaweed processing water consumption in the whole nation is 7200-8640 ten thousand steres.
Seaweed processing waste water caused by current all seaweed processing enterprises is all directly to discharge.Seaweed processing waste water mainly by
The organic matters such as seaweed fragment, soluble protein and silt composition.Seaweed process time concentrates on winter-spring season, and discharge is given up
Water will not show at that time pollution environment harm, with the rise of temperature, the organic matter in waste water starts to ferment, color by
Gradual change is red, until blackening, gives out stench, adds environmental pressure.
Application publication number is the A of CN 102948830, and data of publication of application 2013 year 03 month 06 day, entitled " one kind is to purple

In the specification and entitlement requests book of the patent application, detail how to go the removal of impurity to obtain algae courage egg from seaweed waste water
In vain, and not to isolating the waste water of phycobniliprotein for further processing or being used, also the impurity of removal is not made into one
The processing of step is used, and its content is not useless in order to handle seaweed processing just for the sake of obtaining phycobniliprotein
Water.
The invention provides direct, complete, beyond all doubt technical method, is applied at seaweed processing waste water
Reason field, treated waste water circulation can be made to be reused in seaweed production process, and to the seaweed fragment in waste water, solubility
The organic matters such as protein and silt carry out processing utilization.
The present invention is the improvement of the patent application to Application No. 210710904765.1.
The content of the invention
The problem of causing environmental pollution the invention solves direct discharging of waste water in existing seaweed process.The present invention carries
Direct, complete, beyond all doubt technical method has been supplied, can make the circulation of seaweed processing waste water again using the technical method
Utilize, reduce seaweed processing water resources consumption, the impurity of removal can also carry out down-stream processing with high added-value, reduce environment dirt
Dye, seaweed processing industry chain is elongated, be more beneficial for the cluster development of seaweed industry sustainable health development and seaweed industry.
In order to solve the above technical problems, technical scheme provided by the invention is as follows：
Waste water collection tank, waste water collection tank are masonry concrete structure or steel plate structure or high score
Sub- material structure.Waste water collection tank is that monomer groove can also be the conjuncted groove to communicate with one another that two or more monomer groove is formed.It is useless
Where water collecting groove build laver processing machine at the discharge outlet of factory building, without machining machine and any shape of factory building progress to seaweed
The transformation of formula.
Waste water delivery pump, waste water delivery pump select noncorrosive pump, can be by the purple containing impurity such as seaweed fragment, silts
Dish processing waste water is transported to next procedure.
Waste water separator, there are overfall, sewage draining exit, can be tentatively by the impurity such as silt and seaweed in seaweed processing waste water
Fragment is separated, and the impurity such as silt is discharged through sewage draining exit, and planting vegetable is used for after collection, and the waste water containing seaweed fragment enters
Next procedure.
Waste water filter press, the waste water containing seaweed fragment sent to last process carry out dewater treatment, make seaweed fragment
Separate to form filter cake from waste water Deng solidity material, the filter cake separated there are a variety of processing methods, can direct heap
Fertilizer, feed can be used as, the deep processing raw material oily as taurine, polysaccharide, protein, seaweed is extracted can be carried out.
Separator is precipitated, the waste water that last process is separated, into precipitation separator, precipitation separator is provided with low speed
Agitating device, it can separate the organic matter precipitation in waste water after adding flocculant, flocculant can select inorganic matter to wad a quilt with cotton
Solidifying agent, organic polymer coargulator, biological flocculant etc., the waste water after this process, can be referred to as " reclaimed water ".
Filter press is precipitated, press filtration processing, the liquid separated are carried out to the flocculate precipitate discharged in precipitation separator
Material, which sends precipitation separator and waste water back to and merges precipitation again, to be separated, and obtained filter cake is buried as solid waste or with giving up
The silt discharged in separator merges for planting vegetable.
Membrane filtration system, it is made up of, can filters out exhausted in reclaimed water the ceramic membrane of various membrane fluxs, polymer compound film
