Ecological optimization production process for all-seawater industry

Abstract

The invention aims to provide an 'ecological optimization production process for the all-seawater industry', which is characterized by realizing 100 percent comprehensive utilization of the seawater by the optimization production process which 'circularly extracts and continuously processes the seawater to produce the following three major compound products: marine bio-foods and marine medical products, marine element products and salt chemical products and clean fresh water products. The optimization production process initially provides marine organism pharmaceutical sources for human, eliminates and changes the traditional salt chemical industries and the traditional seawater desalination industries into industrial chain type comprehensive-utilization compound industries with a plurality of salt chemical products rather than the original single products or a fewer varieties of products and supplies cheap and sustainable clean fresh water resources to human beings. The all-seawater-industrial ecological optimization production process has the advantages of reaching zero emission, completely eliminating the ocean pollution caused by 'residual metamorphic seawater', eliminating domestic wastes and realizing ecological environmental protection production.

Description

technical field [0001] The invention relates to a comprehensive utilization of seawater, in particular to an ecologically optimized combined production process for the whole seawater industry. Background technique [0002] 1. At present, in the traditional salt chemical industry and seawater desalination industry, human beings continue to produce some "residual metamorphic seawater" and discharge it into the sea, causing the marine organisms in the discharge area to either die or mutate. Some fish and shrimp mutate even marine organisms. Scientists do not recognize the "monster". For example, in an alkali plant, the remaining brine after extracting and processing alkali from seawater is discharged into the sea; another example is a potassium chlorate plant, and the remaining brine after extracting and processing potassium chlorate from seawater is discharged into the sea; another example is a bromine plant. The element factory, after extracting and processing bromine from s...

Problems solved by technology

[0003] 2. Fresh water resources on the earth's surface are decreasing at a rate of 1.5% per year, while human consumption of fresh water is increasing at a rate of 1.5% per year. If this continues, human survival will soon face a terrible threat due to the lack of fresh water , there is nothing in the world that can replace fresh water, so the only way for human beings to survive is to ask for fresh water from the sea! However, there are two major shortcomings in the traditional seawater desalination technology in the world at present: one is that the production cost of seawater desalination is relatively high, and the average price of one ton of fresh water is more than 1 US dollar, which makes it unaffordable for many people in poor or underdeveloped areas; The concentrated brine (residual metamorphic seawater) left after extracting fresh water has twice the salt concentration of the original seawater and is discharged back into the sea, causing all marine life in some sea areas to die and polluting the sea.

[0004] 3. At present, there is an unsolvable problem in the traditional seawater desalination technology in the world: it is impossible to repeatedly extract the seawater in the process of processing to achieve full utilization, because the remaining salt water after the original seawater is extracted into a part of fresh water contains salt The concentration has doubled, and it can no longer be recycled into the original process, so the remaining "residual metamorphic seawater" has to be discharged back into the sea

In order to allow seawater to be extracted and processed repeatedly, it is necessary to make the salt concentration (Baumé degree) of the remaining seawater consistent with the salt concentration of the original seawater, so that the remaining seawater can be mixed with new seawater into the In the new round of circular extraction process; the traditional salt chemical industry also has the problem that raw seawater can only flow in one direction in the production process. When the required product is extracted from seawater, the remaining "residual metamorphic seawater" It is still discharged back to the sea to pollute the sea, and it cannot be recycled at all.

[0005] 4. At present, human beings have not comprehensively obtained drug resources from marine organisms: seaweed contains plant cytokines (cytoknins) that can promote plant growth and developm...
