Embodiment Construction

[0016] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0017] A method for preparing fresh water by filtering seawater from the seabed, comprising the following steps:

[0018] (1) Positioning, finding any seabed positioning point vertically 2-3km away from the coastline;

[0019] (2) Drilling, drilling an underground well 1-2km deep below sea level at the selected positioning point, and directly extracting underground "small molecule water" (fresh water);

[0020] (3) Obtain the underground fresh water in the underground well, continuously pump the well water, promote the continuous influx of "small molecule water", change the composition of the underground raw water, and gradually form a fresh water storage layer.

[0021] The principle of this method is that seawater is a mixed solution compo...

Abstract

The invention discloses a method for preparing freshwater by filtering seawater by means of a seabed. The method comprises the following steps of 1 positioning, wherein any seabed positioning point of which the perpendicular distance to a coastline is 2 km to 3 km is found; 2 well drilling, wherein an underground well which is 1 km-2 km deep below the sea level is drilled at the well-selected positioning point; 3 obtaining underground freshwater in the underground well. The method for preparing the freshwater by filtering the seawater by means of the seabed has the advantages that the seawater desalination cost is reduced, actual operation is convenient, and meanwhile the method is more beneficial for promotion and popularization of seawater desalination.

Description

technical field [0001] The invention relates to a method for preparing fresh water converted from seawater, in particular to a method for preparing fresh water by filtering seawater on the seabed. Background technique [0002] Seawater desalination is the use of seawater desalination to produce fresh water. It is an open source incremental technology to realize the utilization of water resources. It can increase the total amount of fresh water without being affected by time, space and climate. The water quality is good, and it can guarantee the stable water supply of drinking water for coastal residents and industrial and agricultural production. The process of obtaining fresh water from seawater is called seawater desalination. The seawater desalination methods currently used include seawater freezing, electrodialysis, distillation, and reverse osmosis. [0003] However, in the prior art, the cost of seawater desalination is very high, which prevents large-scale applicatio...
