Further, described artificial environment is suitable for supporting ocean fishes or shrimp, artificial cultivation ocean fishes and shrimp to the requirement of water environment very
Height, volume production to be realized, it is necessary to be controlled by the various nutritional labelings of water environment, the mentioned component content in strong brine is relatively
Height, will be allocated by introducing sea water and related nutritional material, thus the yield realizing artificial cultivation ocean fishes and shrimp is increased,
The most both avoid the discharge of strong brine, it is achieved that the zero-emission after Seawater Treatment, effectively make use of the nothing in strong brine
Machine acid or salt, achieve again the purpose of artificial cultivation marine product, it is possible to the environment of conservative control artificial cultivation, thus controls to produce
Amount.
One seawater comprehensive utilizing method of the present invention, has a following beneficial effect:
The seawater comprehensive utilizing method of the present invention, effectively can all reclaim stage products therefrom each after Seawater Treatment and follow
Ring utilizes.The concentrated seawater produced currently for sea water desalinating unit mainly uses and in line enters to enter sea or straight after sea, dilution
Enter deep-well etc..In terms of the sea water desalinating unit of daily output desalination water 6 kiloton, every day will generate the concentrated seawater of 10.8 kilotons.Wherein
Still containing NaCl more than large quantity of moisture, and 420 tons and other salt a certain amount of.Using concentrated seawater as discharging of waste liquid, not only
Environment is caused reality or potential impact, and then changes the ecological balance of ocean, and abandoned whole salts and
Water resource, it is clear that the seawater resources of preciousness could not be made full use of, be allowed to lose after having got it.Additionally, enter deep-well sooner or later
Land can be polluted；Rush dilute heel row sea and more waste freshwater resources.The seawater comprehensive utilizing method of the present invention, first passes around filter institute
Obtaining solid matter and can prepare feedstuff, the sea water of desalination can directly be drunk, and the strong brine after desalination can be formulated as people
The water environment of work cultivation seafood, it may be said that achieve Seawater Treatment and achieve zero-emission, decrease pollution, create very meanwhile
