As shown in Table 1, the underground brine of coastal submarine rocks is characterized by the presence of Ca (Na) -Cl type saline groundwater, although the Na content is lower than that of seawater. The salt water of the sea bed rocks are mineralized by mineralization and long-term existence at high pressure, and the half-width value (㎐) of the nuclear magnetic resonance (Nuclear Magnetic Resonance) ¹⁷ O- It is known that there is also a characteristic that the surface tension is small and permeability is good.

Seawater such as surface sea water, deep ocean water, underground rock salt water in the coastal area, underground rock salt water in the island area, or underground rock salt water in the island region contains almost all of the elements present in the earth, ) And some of the substances excreted by marine organisms have inhibited the development of melanin which is a cause of spiny-freckles and atopy dermatitis caused by eosinophils by inflammatory substances such as histamine Improvement of natural healing power and improvement of mind and body due to activation of macrophage, a large amoeba phagocytic cell which predates and digests germs, viruses, reticulocytes, foreign substances, etc. , And is widely used in marine therapy (Thalassotherapy) to promote health promotion.

Thalassotherapy uses sea water, seaweed and sea mud to enhance the natural healing power of the human body and provides relief as a part of treatment of body function or health recovery by rehabilitation therapy. (Bretagne), the birthplace of marine therapies, refers to the totalitarian treatment of marine climate and the use of marine resources. For example, when looking at the sunset, The feeling of "sea" as a sensation is also considered as one of marine therapy. In recent years, people who are tired and mentally exhausted from precautionary medicine have increased their use for relaxation, relaxation and leisure. have.

And marine therapy has seven kinds of circulatory activity (self-activity) such as blood circulation, energy circulation, epidermal circulation, dermis circulation, cell circulation, lymphatic circulation and emotional circulation.

In particular, deep sea water is a natural resource that has been repeatedly decomposed-metabolized-recomposing over many years by sedimentation of marine animals and plants (seaweeds, marine, fisheries, plankton, etc.) into the sea. As a result, in the deep sea bed which is deeper than 50 m in depth from sea level, substances that activate macrophages, which stimulate leukocytes, are present in more deep water than in surface waters, .

Sea water supports improvement of mind and body sluggishness, and marine therapy which promotes health promotion can activate our vitality by the power of sea which is the source of life.

The sea, which is the source of all life, contains almost all of the minerals that are currently being identified. Such seawater contains various minerals and various kinds of useful substances, so by bathing it, The metabolism of the skin can be increased and the balance of the skin can be improved.

In the present invention, the surface sea water, the deep ocean water of deep sea depths deeper than 200 m from the sea surface, the underground rock salt water of the coastal area, The present invention relates to a method for treating seawater such as underground rock salt water or submarine underground rock salt water of an island region with a bath water of a seawater, and will be described in detail with reference to the accompanying drawings.

Ⅰ. Seawater intake and pretreatment filtration step

The deep sea water (deep sea water), the underground rock salt water in the coastal area (coastal area), the island area (coastal area), the deep sea water (deep sea water) (SS) is 20 ~ 50mg / ℓ. The concentration of suspended solids in the water is 20 ~ 50mg / ℓ by sand filtration after taking seawater such as underground rock salt water or submarine underground rock salt water. Pre-treatment in the range The filtered water is sent to the sterilization treatment stage.

Surface water or deep seawater can be taken by installing a pipeline on the sea bed and taking the water by a pump or installing the water intake below the sea level, taking it by the Siphon principle and sending it to the catchment tank.

And seawater intakes such as underground rock salt water in coastal areas, underground rock saltwater in island areas, or submarine underground rock salt water are underground rocks, (Intake water) to the aquifer of the aquifer, and the water intake pump is installed in this water intake, and the underground salt water is taken by the water intake pump and sent to the water collection tank.

The excavation of the intake hole is performed by excavating the alluvial zone to the hard rock line after installing the external casing. At this time, the initial ground excavation diameter should be at least 100 mmφ Or more.

In order to prevent the inflow of contaminated water from the upper part after the completion of the upper section of the upper section, the grouting is performed by reverse cyclic pressure cement grouting from the bottom of the lower part of the injection molding machine to the space between the casing and the lower part. . The grouting material uses a cement mixture containing about 3 vol% of bentonite.

After the grouting is completely solidified, it is drilled to the lower aquifer with a diameter of about 150 ~ 250mmφ, and the TV camera is verified in the ball to check the grouting construction condition, casing installation condition and aquifer condition. Install a pump and install a measuring device and a protective device to automatically measure the amount of water withdrawn.

In addition, a monitoring and continuous automatic measuring device (water level of the raw water, electric conductivity, temperature, pH, etc.) is installed in the intake. The underground brine water taken in the above-mentioned water storage tank is transferred to the collection tank.

The collecting tank is equipped with a sealed lid and a sterilizing device and an air filter are installed.

The seawater stored in the collecting tank is sent to a sand filtration tower filled with sand in the pretreatment filtration process to remove suspended solids (SS) in the water, and then sent to a sterilization treatment stage.

The sand filling the sand filtration tower is filled with sand having an effective size of 0.45 to 0.7 mm, a uniformity coefficient of 1.7 or less, a maximum diameter of 2.0 mm or less, and a minimum diameter of 0.3 mm or less. If it is inevitable, it shall be 1% or less of the maximum diameter and the minimum diameter.

The sand filtration tower is subjected to rapid sand filtration or slow sand filtration, and one of the two is selected depending on the yield and the concentration of suspended solids in water. In the case of rapid sand filtration, the filtration rate is 120 to 200 m / Is designed to be 60 to 70 cm. In case of rapid sand filtration, the filtration speed is designed to be 4 to 5 m / day, and the thickness of the outer layer is designed to be 70 to 90 cm.

If the turbidity of the seawater is less than 2 degrees (NTU, Nephelometric Turbidity Unit) and the concentration of the suspended solids is low, the sand filtration is omitted and the collected seawater is sent to the sterilization treatment step.

 Ⅱ. Sterilization treatment step

Generally, sterilization of water can be performed by heat sterilization heated to 110 to 120 캜, heat sterilization under high pressure, sterilization by ultraviolet irradiation, sterilization by irradiation with radiation (? -Ray), sterilization by irradiation with heat or photo- Sterilization by injecting an oxidizing agent (sterilizing agent), sterilization by discharging treatment of a high frequency high-voltage power source, sterilization by a pressurizing energization treatment, pulses of an ac electric field (AC high electric field) , Disinfection by joule's heat generated by energization by application of AC power, sterilization by energization of direct current power, or magnetization treatment (also referred to as magnetic treatment). The sterilization treatment is carried out by the combined method.

Chlorine seawater (Cl _2), chlorine dioxide (ClO _2), hypochlorite (NaClO, KClO, Ca (ClO) _2, etc.), oxidizing chlorine (Cl ₂ O), chloroisatin isocyanurate (Chloroisocyanurates), hydrogen peroxide (H ₂ Sterilization by an oxidizing agent such as ozone (O ₂ ) or ozone (O ₃ ), sterilization by irradiation with radiation (? -Ray), sterilization by irradiation of an electron beam, sterilization by electric oxidation, sterilization by discharge treatment of a high- (Bromate salt), hydrochloric acid (HClO ₃ ), chloroacetic acid, dichloroacetic acid, chloroform, and the like, which are harmful to the human body, Oxidation reactants such as Dibromochloromethane, Trihalomethane, Trichloroacetic acid, Bromoform, Bromodichloromethane, Formaldehyde and the like, Can be generated Sterilization method that an oxidizing agent or oxidizing substances generated because shall not.

In the present invention, the sterilization treatment is a method of sterilization treatment by magnetization treatment in which harmful substances are not generated in the human body and constant voltage treatment by AC high voltage is referred to in Fig. 2 "sterilization treatment process chart" The details will be described below.

1. Magnetization process

After the pretreated and filtered seawater is supplied to the seawater storage tank 1, the pretreatment filtered seawater is supplied to the magnetizing apparatus 3 by the seawater transfer pump 2 and magnetized, and then sent to the sterilizing treatment tank 4.

The magnetizing apparatus 3 is provided with a coil coil wound around a cylindrical conductive tube made of an insulating material such as synthetic resin (PVC, PE, styrene resin, etc.), ebonite, FRP, Bakelite, A solenoid type magnetization device in which a magnetic field is formed inside a coil by applying a low voltage current in a range of a magnetic field density of 10,000 to 15,000 G (Gauss) One type of magnetizing device in which permanent magnets magnetized in a range are provided.

When the fluid (water) passes through the magnetic field between the N-pole and the S-pole of the magnetizing device 3 in a direction perpendicular to the magnetization direction, electromotive force is generated by MHD (Magneto-Hydro-Dynamics) (Surface tension) becomes small as the group of water molecules collapses and collapses due to the action of water (wave), so that the permeability (permeability) becomes high and the water is reformed as the oxidation-reduction potential decreases. In addition, bacteria such as Escherichia coli, Legionella, and resistant bacteria contained in water are killed, and bacterial cells are destroyed to sterilize or inhibit the growth of bacteria.

Since the sterilization treatment by the magnetization treatment can be further combined with the other sterilization treatment methods mentioned above, the sterilization treatment efficiency can be further improved. Therefore, in the present invention, after the sterilization treatment by the magnetization treatment, And a sterilization treatment by a constant voltage treatment by a high voltage are combined to provide a sterilization treatment method in which an adverse reaction product harmful to the human body is not produced.

Important functions such as bacterial cell division and cell membrane osmotic pressure regulation are controlled by weak electrical signals (pulse signals) in the cell. When the water is magnetized in the magnetic field of the magnetizing device, a direct current flows through the electromotive force, and when a direct current is applied to the cell membrane of the bacteria contained in the water, an abnormality occurs in the command system due to the pulse, The osmotic pressure regulating function is interfered with, and finally the cells of all the bacteria can be killed.

The generated voltage E when the pretreated and filtered seawater passes through the magnetic field between the N and S poles of the magnetizing apparatus 3 in a direction perpendicular to the surface of the magnetizing apparatus 3 is the difference between the flow velocity V of water and the N pole and the S pole of the magnetizing apparatus 3 And the MHD potential difference is proportional to the magnitude of the magnetic force and the flow rate of the fluid.

E = V x B ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... (17)

In the magnetizing treatment, the higher the magnetic force (magnetic flux density) of the magnetizing apparatus is, and the greater the flow velocity of the fluid passing through the magnetic field is, the higher the magnetizing treatment efficiency is. Therefore, in the present invention, a magnetic field having a magnetic flux density of 4,000 to 12,000 G (Gauss) is used, and the cross-sectional area of the magnetic field is set so that the flow rate of the fluid passing through the magnetic field is in the range of 2 to 6 m / sec.

When the flow rate in the magnetic field is 2 m / sec or less at the flow rate supplied from the seawater delivery pump 2 to the magnetizing apparatus 3 because the processing capacity is smaller than that in the normal operation, the flow rate of the fluid discharged from the magnetizing apparatus 3 A part of the water is returned to the seawater storage tank 1, and the flow is operated so that the flow rate is 2 m / sec or more in the magnetic field.

It is preferable that the permanent magnets use neodymium magnet (Nd-Fe-B) or samarium cobalt magnet (Sm-Co) having high magnetic flux density. Because the magnetization is processed in a very short picosecond (Picosecond). The residence time of the fluid in the magnetic field is not a big problem.

When the pollution degree of the harmful microorganisms is low, the above-mentioned magnetization treatment step is omitted, and when the pretreated and filtered seawater is supplied to the seawater storage tank 1, the sterilization process by the AC high voltage To the sterilization treatment tank (4).

2. Sterilization process by AC high voltage (AC high voltage)

[ Then, the AC high voltage generating device 8 is grounded (8g) to the ground.

An alternating current power of 110 to 220 volts is connected to the AC high voltage generating device 8 and the variable resistor 8a is adjusted so that an alternating current of 6,000 to 10,000 Volts is generated from the secondary output terminal 8e of the transformer When a high voltage is applied to the high-voltage applied electrode 5 of the sterilization treatment tank 4, a constant voltage is generated between the ground electrodes 6 grounded to the ground 7, And sterilized.

The capacity of the sterilization treatment tank 4 is determined based on the state of seawater and the applied voltage of the AC high voltage, but it is generally 4 to 6 hours. The sterilization treatment tank 4 is made of a salt-resistant and corrosion-resistant material. One of the epoxy resin, glass fiber reinforced plastic and rubber is coated on the concrete structure ), Or lining, PVC (Polyvinyl chloride), ABS (Acrylonitrile butadiene styrene copolymer), PE (Polyethylene), Polyethylene (PP), Titanium or Salt resistant steel.
