PROBLEM TO BE SOLVED: To provide a seawater desalination system which effectively functions as a countermeasure for draught and a countermeasure for afforestation of desert in a system of desalting and utilizing nearly the infinite seawater and is helpful for water shortage at a low cost. SOLUTION: The sea water desalination system is a mechanism of allowing the seawater to dive into multiple layers of the sand as a practical filter, so as to stick its salt component to the particles of the sand, then once pouring the water into a river installed under the ground and moving the seawater, then pumping up the water from a well after carrying the water to a necessary place by noticing the performance of the sand to stick the salt component in a salt making process in a salt farm. At this time, the separation of the moisture and the salt component is made thorough by covering the ceiling of the river under the ground with cloth or materials, such as spongy materials, and using the ceiling materials which do not allow the permeation of the sand and allows the permeation of the water. The water is pumped up by utilizing wind power generation in continuously supplying a large volume of the seawater from the inside of the sea and therefore the desaaliation is made possible at the extremely low cost. According to the present invention, the system is greatly helpful for the countermeasure for the drought of the earth. COPYRIGHT: (C)2005,JPO&NCIPI
