Method and system for preparing drinking weak alkali water and strontium-rich electrolyte raw water from salt-making distilled water

A method of preparing drinking weak alkali water and strontium-rich electrolyte raw water comprising:

• (1) carrying out pressure reduction treatment on a salt and electrolyte-containing, salt-making distilled water to obtain a first treated water;
• (2) conducting primary filtration treatment on said first treated water to obtain a second treated water;
• (3) performing membrane separation treatment on said second treated water to respectively obtain permeated water and retentate water;
• (4) performing activated carbon adsorption treatment on the permeated water to obtain third treated water A and performing activated carbon adsorption treatment on the retentate water to obtain a third treated water B;
• (5) carrying out secondary filtration treatment on the third treated water A to obtain fourth treated water A and carrying out secondary filtration treatment on the retentate water to obtain a fourth treated water B;
• and
• (6) sterilizing and disinfecting the fourth treated water A to obtain weak alkaline drinking water and sterilizing and disinfecting the fourth treated water B to obtain strontium-rich electrolyte raw water.
