Production process for achieving hundred-percent comprehensive utilization and zero emission by recycling and extracting seawater

Abstract

The invention aims at providing a production process for achieving hundred-percent comprehensive utilization and zero emission by recycling and extracting seawater, which is characterized by recycling, extracting and processing used seawater, realizing the all-sided and hundred-percent comprehensive utilization to seawater, eliminating production wastes, thoroughly eliminating the pollution to oceans from 'disabled seawater', creating marine organism medicine sources for serve all mankind, providing low-cost and unexhausted clean fresh water resource for mankind, ensuring that salt chemical engineering industry becomes a plurality of compound three-sort products in an industry-chain type: marine organism medical products, seawater element products and salt chemical engineering products from the original single products, cleaning fresh water, achieving the hundred-percent comprehensive utilization to seawater and realizing clean production and zero emission.

Description

technical field [0001] The invention relates to a comprehensive utilization of seawater, in particular to a production process for realizing 100% comprehensive utilization and zero discharge of seawater through repeated circulation and extraction. Background technique [0002] 1. At present, human beings are constantly creating some "disabled sea water" to discharge into the sea, causing the marine life in the discharge area to either die or mutate, and the mutated "monster" even marine biologists do not recognize. 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 skunk The remaining seawater is discharged into the sea after extracting and processing stinol from seawater; the salt chemical production factories ...

Problems solved by technology

[0003] 2. At present, the desalination technologies of the United States, Israel and Japan are used in the desalination of sea water in the world, because their desalination technologies are relatively advanced, but their sea water desalination technologies have two major shortcomings: First, the production cost of sea water desalination is relatively high A ton of fresh water costs more than US$1 on average, making it unaffordable for many people in poor or underdeveloped areas; second, the concentrated brine (disabled sea water) left after extracting fresh water is discharged back into the sea, causing the death of all marine life in some sea areas

[0004] 3. At present, there is an unsolvable problem in the seawater desalination technology in the world: it is impossible to repeatedly extract seawater, because the salt content of the remaining saltwater after the original seawater is extracted into fresh water increases, so the
