Abstract
A double-membrane seawater desalination process specifically comprises the following steps: (1) taking shells aged for two years; (2) crushing the shells into particles; (3) adding the crushed shellsinto a packed tower; (4) fully mixing raw water and carbon dioxide in a mixer; (5) adding a carbon dioxide aqueous solution generated in the step (4) into the packed tower; (6) adding the water produced in the packed tower in the step (5) into a filter through a water pipeline; (7) adding the water filtered in the step (6) into an ultraviolet sterilization device; and (8) putting the product waterin the step (7) directly into a drinking water storage tank for backup. The method has the beneficial effects that the hardness and mineral content of the produced water can be improved, the production efficiency is improved, the cost is saved, the produced water meets the requirements of drinking water, and the precipitation content of the trace element strontium reaches the standard of drinkingnatural mineral water.
