Combined production process of low cost zero discharging sea water desalting comprehensive use

Abstract

A low-cost non-pollution process for desalinating seawater and reclaiming its resources includes such steps as pre-treating seawater for cleaning it, concentrating by electric dialysis unit and low-temp vacuumizing pump to obtain saturated saline and diluted saline, extracting various chemicals from said saturated saline, extracting fresh water from diluted saline, and returning the residual saline back to seawater cleaning pool.

Description

technical field

[0001] The invention relates to seawater desalination, in particular to a combined production process technology for comprehensive utilization of low-cost zero-discharge seawater desalination. Background technique

[0002] Water is the source of life on which all creatures in nature rely for survival. Because of water, there is life on the earth. Since the 18th century, due to the rapid development of industry and the rapid growth of human reproduction, the ecological environment on the earth's surface has continued to deteriorate. More than 60% of the original forests in the world have been destroyed, and the entire earth's ecology has lost its balance. The fresh water resources that human society depends on It is also constantly decreasing, and many rivers have become dry rivers. However, the consumption of domestic water and industrial water necessary for human beings is increasing year by year, and an irresistible contradiction is formed between the redu...
