The improvement of patent application.
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, using the technical method seaweed processing waste water Xun Huan can have been made sharp again
With, seaweed processing water resources consumption is reduced, the impurity of removal can also carry out down-stream processing with high added-value, reduce environmental pollution,
Seaweed processing industry chain is elongated, is more advantageous to the cluster development of seaweed industry sustainable health development and seaweed industry.
In order to solve the above technical problems, technical solution provided by the invention is as follows：
Waste water collection tank, waste water collection tank are masonry concrete structure or steel plate structure or macromolecule
Material structure.Waste water collection tank is that monomer slot can also be the conjuncted slot to communicate with one another that more than two monomer slots are formed.Waste water
It is any type of without being carried out to seaweed machining machine and workshop where collecting tank build laver processing machine at the discharge outlet of workshop
Transformation.
Waste water delivery pump, waste water delivery pump select noncorrosive pump, can be by the seaweed containing impurity such as seaweed fragment, silts
Processing waste water is transported to next procedure.
Waste water filter press is carried out dehydrating the waste water that last process is sent, and solidity substance is made to be separated from waste water
Out form filter cake, the filter cake separated there are many processing method, can directly compost, can as feed, can carry out
Deep processing is as the raw material for extracting taurine, polysaccharide, protein, seaweed oil.
Separator is precipitated, the waste water that last process is separated, into precipitation separator, precipitation separator is stirred equipped with low speed
Device is mixed, can separate the organic matter precipitation in waste water after adding in flocculant, flocculant can select inorganic matter to flocculate
Agent, organic polymer coargulator, biological flocculant etc., the waste water after this process can be referred to as " middle water ".
Filter press is precipitated, press filtration processing, the liquid separated are carried out to the flocculate precipitate discharged in precipitation separator
Substance sends precipitation separator back to, and precipitation separates again with waste water merging, and obtained filter cake is buried or is used for as solid waste
Planting vegetable.
Membrane filtration system is made of the ceramic membrane of various membrane fluxs, polymer compound film, can be filtered out exhausted big in middle water
Partial impurities.
Sterilization process is made of ozone sterilization and ultraviolet disinfection.
