Problems solved by technology

[0003] However, after people use seawater desalination devices to extract fresh water from seawater, the salt is trapped in the by-product-concentrated water, and this part of the concentrated water is often directly discharged back into the sea, causing serious waste

Embodiment 1

[0037] Measure and compare the water quality indicators of raw water and concentrated water. Use beach deep well water with a salt content of 17‰ as raw water to produce seawater aquaculture water with a salt content of 30‰. The water quality of the original deep well water is determined as follows: salinity is 17‰, pH is 7.55, Ca 2+ The concentration is 640ppm, Mg 2+ The concentration is 460ppm, the total alkalinity is 85ppm, and the ammonia nitrogen concentration is 0.06ppm. The water quality of the final concentrated water is determined as follows: salinity is 30‰, pH is 8.05, Ca 2+ The concentration is 340ppm, Mg 2+ The concentration is 995ppm, the total alkalinity is 120ppm, and the ammonia nitrogen concentration is 0.06ppm. The result is very close to the water quality index of natural seawater with a salt content of 35‰.

[0038] Use the prepared concentrated water to culture Penaeus vannamei shrimp, first use aeration to maintain sufficient dissolved oxygen (greate...

Abstract

The invention belongs to the technical field of sea water desalination and particularly relates to a method of using deep sea simulated water to cultivate deep sea marine organisms, comprising: usingshallow sea water, sub-sea water or costal deep well water having low salinity of 5%. To 20%. as original water to perform pretreatment, decreasing turbidity of the original water to 1 ppm and below,nano-filtering the pretreated original water to obtain nano-filtered water, and subjecting the nano-filtered water to reverse osmosis treatment to obtain concentrated water, similar to deep sea water,having the salinity of 28%. To 36%.; using the concentrated water to cultivate marine organisms in deep sea environments. The method provided herein has the advantages that influence of natural disasters such as storm, red tide and typhoons can be greatly avoided so that dependence on weather avoided; in addition, the method may provide fewer limits so that popularizing sea water cultivation to the inland is made possible.

Description

technical field [0001] The invention belongs to the technical field of seawater desalination, and in particular relates to a method for simulating water quality of deep-sea seawater for cultivating deep-sea marine organisms. Background technique [0002] With the expansion of the world's population and the rapid development of the economy, the crisis brought about by the shortage of water resources has become increasingly serious. The ocean area on the earth accounts for more than 75% of the total area of ​​the earth, and seawater resources are abundant. However, the freshwater resources that can be directly used in fact only account for 0.77% of all water resources. Seawater desalination technology is an emerging technology developed under such a background. [0003] However, after people use seawater desalination devices to extract fresh water from seawater, the salt is trapped in the by-product-concentrated water, and this part of the concentrated water is often directly...
