Description
Technical field
The present invention relates to the comprehensive utilization of a kind of seawater, particularly relating to circulates repeatedly to seawater extracts the producing and manufacturing technique of realizing 100% comprehensive utilization and zero release.
Background technology
One, the mankind cause marine organisms or death in the discharge areas constantly making " disabled seawater " to discharging greatly in the sea at present, or variation, and what the Marine Biologist of variation did not also recognize " monster ".As an alkali factory, from seawater, extract and process the salt solution that remains after the alkali and all discharge marine greatly; Potcrate factory for another example extracts from seawater and processes the salt solution that remains after the Potcrate and all be discharged into marine greatly; Smelly plain factory for another example extracts from seawater and processes the seawater that remain after the smelly element and all be discharged into big nautical mile; The single salt chemical engineering of these products production plant, they discharge back the remaining composition " disabled seawater " that lacks marine greatly again after extracting their desirable ingredients from seawater or in the Industrial Salt.Marine organisms can't be adapted to and dead or variation! Territory, the coastal waters maritime interior waters of the long-term like this edge of continental shelf of going down will day by day worsen, and the culture fishery in coastal waters and coastal waters are pounced on to drag for and already will hurriedly be degenerated, and the mankind can suffer the revenge in sea for the pollution behavior of oneself sooner or later.
Two, present sea water desaltination in the world all is a desalination techniques of using the U.S., Israel, Japan, because their desalination techniques is more advanced, but their desalination technology exists in two very big shortcomings: the one, and the production cost of sea water desaltination is than higher, one ton of fresh water can not use a lot of poverties or people from low developed area on average more than 1 dollar; The 2nd, extract the strong brine (disabled seawater) that remains after the fresh water and flow back to the sea again, cause the marine organisms in local marine site all dead.
Three, at present there is an insurmountable difficult problem in the whole world desalination technology: can't accomplish with the seawater extraction that circulates repeatedly, because remaining salt solution saltiness had improved after former seawater was extracted out a part of fresh water, residual seawater have to be discharged back in the sea big.Want to allow the seawater extraction that can circulate repeatedly, the salt concentration (degree Beaume) of seawater is consistent with the salt concentration of former seawater down just must to make residue, the seawater that remains could be admixed in the circulation extraction flow process that enters a new round with new seawater.
Four, at present the mankind also do not carry out to marine organisms comprehensively and ask for drug resource, contain vegetable cell kinetin (cytoknins) in the marine alga, Sargassum polysaccharides, phycobiliprotein, seaweeds carotene, different unsaturated fatty acidss (the AA that is contained in long-chain highly unsaturated fatty acid (PUFA) and the different marine alga, LNA, EPA, DHA), the precious industry that all is in the terrestrial plant not contained, food, medical material, as have very that Johnson ﹠ Johnson manages active unsaturated fatty acids docosahexenoic acid (DHA) and timnodonic acid (EPA) can make people's arteries softness that extensibility is arranged, reduce cholesterol and neutral fat content in the blood, suppress platelet aggregation, therefore blood viscosity lowering also just can treat human myocardium's infraction, a series of cardiovascular disordeies such as cerebral thrombosis.Long-chain highly unsaturated fatty acid n-3 series can have therapeutic action to disease of immune system such as sacroiliitis, lupus erythematosus, asthma, ulcerative enteritis, ephritis, alopecias; Seaweeds carotene can not the synthetic vitamin A because of having anti-oxidant activity and having anti-cancer function and contain human body.The halobios medicine source mankind of the preciousness that is not contained in these terrestrial plants but can not comprehensively develop at present, should be the things that part be it's a pity, otherwise cardiovascular disorder can not become human first dead disease yet.
In view of above-mentioned present situation, in order thoroughly to eliminate pollution that " disabled seawater " cause the ocean, bring benefit to the mankind, to obtain cheap eternal Freshwater resources in order to make the mankind in order to open up the halobios medicine source, the application proposes seawater is realized that the novel process of circulation extraction processing is put method repeatedly, comprehensive comprehensive utilization with seawater 100%, realize the bad habit in the thorough decontamination of zero release sea, change the backward production technique that " disabled seawater " discharges to the sea in traditional salt Chemical Manufacture factory and traditional sea water desaltination enterprise, make human comprehensively Utilization of Seawater by Solar; In the seawater cleaning process, miniature algae held back to separate and be processed into edible product of precious marine organisms and pharmaceutical products; Extract with element such as the chlorine in the seawater, sodium, magnesium, sulphur, calcium, potassium, smelly, carbon, strontium, boron, silicon, fluorine or by the various salt chemical products that these element chemical combination are formed again and process; Finally can obtain a large amount of clean fresh water again, solve human demand fresh water.Like this, the ocean can be cleaned, precious marine organisms medicine, salt chemical product and the clean fresh water society that brings benefit to the mankind can be obtained again.
