Abstract
The present invention comprises a well (10) installed to receive groundwater in a coastal area; (100) for supplying fresh water to the lower part of the well (10) so as to prevent seawater from penetrating into the well (10) It prevents seawater penetration phenomenon of groundwater so that fresh water can be collected stably.
Description
Field of the Invention The present invention relates to the field of environment, and more particularly to the structure of wells.
Groundwater is generally used to secure water resources in coastal areas such as Jeju Island and islands and the East Coast.
In coastal aquifers, the freshwater layer and seawater entering the sea from land are balanced by density, which is known to be governed by Ghyben-erzberg's law.
When the groundwater is taken in excess of the amount available in the area, the groundwater (a) is lowered and seawater penetrates, making the groundwater unavailable. When the sea water surface (c) rises and seawater intrudes into the aquifer , The water quality of the
In recent years, the use of seawater as a source of water has been increasing in order to reduce the amount of groundwater as a freshwater source in island and coastal areas. However, seawater desalination facilities have caused a great increase in water treatment costs, In the region, it is difficult to produce water in winter with low water temperature.
Therefore, the maintenance of freshwater aquifers in the coastal region is a very important problem in the area where island and coastal groundwater are used as a source of water.
SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a structure for preventing seawater infiltration of groundwater by preventing low- And to provide a method of prevention.
In order to solve the above problems, the present invention provides a water treatment system comprising: a well (10) installed to receive groundwater in a coastal area; (100) for supplying fresh water to the lower part of the well (10) so as to prevent seawater from penetrating into the well (10).

The method of preventing seawater infiltration of a well using the seawater infiltration preventing structure according to the present invention comprises the steps of: installing the uplifting structure (100) around the well (10) installed in a coastal area; And supplying the fresh water to the submerged structure (100) to supply fresh water to the lower part of the well (10).
It is preferable to use heavy water as the fresh water.
The cultivation step is preferably carried out during the tide.
The present invention proposes a structure for preventing seawater infiltration of a well and a method for preventing seawater infiltration using the same, which can prevent seawater infiltration phenomenon of groundwater at low cost in the island and coastal area, thereby stably obtaining fresh water.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
As shown in FIG. 2 and subsequent drawings, the structure for preventing seepage of a well according to the present invention basically comprises a well 10 installed to receive groundwater in a coastal area; (100) for supplying fresh water to the lower part of the well (10) so as to prevent seawater from penetrating into the well (10).

Although it is possible to use a constant water as the fresh water, it is more preferable to utilize the same water as the sewage reuse water, because the water permeated into the ground is collected through the
On the other hand, the sea water underground water surface (c) varies in height according to the difference of the tide water level. It is effective to perform the upwelling work in the tide where the sea water underground water surface (c) is the highest.
It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention as defined in the appended claims. It is to be understood that both the technical idea and the technical spirit of the invention are included in the scope of the present invention.
