Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a deep ocean water treatment plant obtained by collecting seawater having a depth of 200 m or less. 2. Description of the Related Art Deep sea water, which is a seawater at a depth of 200 m or more, has low pollution and little marine bacteria and is clean. It contains a lot of necessary nutrients such as nitrogen and silicic acid, and has a good mineral balance, so this deep water is collected and used for foods such as drinking water and fermented foods, medical and health products such as pharmaceuticals and cosmetics, aquaculture, It is used in a wide range of fields such as agriculture and fisheries such as soil improvement. [0003] However, conventional deep sea water treatment systems are relatively compact and lack mass production, and are therefore expensive to produce, and can reduce the cost of the final product. There was an inconvenience of not being able to do so. [0004] It is an object of the present invention to provide an inexpensive and highly safe deep-sea water treatment plant that enables a large amount of deep-sea water treatment. [0005] The present invention can solve the above-mentioned problems by providing the following structure. (1) One or more deep water sampling pipes capable of sampling deep sea water having a depth of 200 m or more, one or more deep water storage tanks connected to the sampling pipes and provided through a pumping pump, etc. A coarse filtration tank, a desalination tank, a membrane separation module tank, an ozone sterilization tank, and an activated carbon filtration tank which are sequentially connected to the storage tank are provided, and the deep water storage tank is provided.
Is a deep-sea water treatment plant characterized by vertically rotating stirring blades inside . [0008] Embodiments of the present invention will be described below. FIG. 1 is an overall external view showing one embodiment of a deep-sea water treatment plant according to the present invention. Reference numeral 1 denotes a deep water sampling pipe having an open end opened at a depth of 200 m or more in the ocean 2, and two pipes are arranged in parallel in FIG. 3 is the deep water sampling pipe 1
And the deep water storage tank 4 provided at least one of the following stages
1 shows a building provided with a pump 5 connected to the ocean, and the deep pump water of the ocean 2 having a depth of 200 m or more can be collected and stored by the action of the pump 5. In the drawing, the pipes 6 from the pump 5 to the three deep water storage tanks 4 of 200 ton class are sequentially connected to the lower part of each tank 4, but the upper part is connected to each tank 4. Alternatively, it may be supplied downstream (not shown). 7 is each tank 4
The deep sea water stored in the tank 4 is constantly or as required stirred by the stirring blades disposed therein, thereby achieving uniformity of the contained components. Since the above-mentioned pump 5 has an electric control mechanism, it is preferable to install the pump 5 in the covered building 3. The other plurality of deep water storage tanks 4 are preferably located close to the ocean 2, but may be installed directly without cover in a leveled outdoor space even at a place away from the ocean 2. Reference numeral 8 denotes a coarse filtration tank connected to the storage tank 4 so that impurities, dust and the like contained in deep sea water can be removed by passing through various built-in filters. Reference numeral 9 denotes a desalination tank connected to the coarse filtration tank 8, and a reverse osmosis membrane (REVERSE OSMOSI).
According to S), pure water can be obtained by eliminating salts in the deep sea water and microorganisms harmful to the human body. 10
Is the next stage of the membrane separation module tank, which can remove finer dust, odor and dirt. Reference numeral 11 denotes an ozone contact tank which is continuously connected. The ozone contact tank is sprayed with ozone gas to the purified deep water to perform a sterilization treatment, and is supplied to an activated carbon filtration tank 12 at the final stage to be treated with water. Absorb the impurities in the deep water to obtain the final treated deep water. The coarse filtration tank 8, the desalination tank 9, the membrane separation module tank 10, the ozone contact tank 11 and the activated carbon filtration tank 12 are arranged side by side on a platform 13 as a series of continuous devices. However, the arrangement is free and can be rearranged. Reference numeral 14 denotes other piping, and reference numeral 15 denotes a lorry vehicle. The truck is guided to a carriage 16 adjacent to the platform 13, where the purified water obtained through the activated carbon filtration tank 12 at the final stage is supplied with necessary piping. It can be supplied and shipped into the tank of the lorry 15 from the supply port 17 of 14. Reference numeral 18 denotes a frame that supports the upper portion of each of the above-mentioned devices provided on the platform 13, and 19 denotes a staircase 20.
1 shows a deck on which a worker can get on and off and walk to check each device. Reference numeral 21 denotes a spiral staircase disposed along the outer wall of the tank 4, and reference numeral 22 denotes a motor for rotating the stirring blades 7 provided at the center of the upper lid of each tank 4. Although not shown, the coarse filtration tank 8 provided on the platform 13 is provided with a supply cock so that it can be sold and supplied as seawater for living cages or seawater such as an aquarium. Is provided with a device for removing the salt by-product to be removed, and the salt by-product to be extracted can be sold and provided as a raw material for various salts. With the above construction, the deep sea water having a depth of 200 m or less can be constantly stored and stored in the deep water storage tank 4 on the ground by the pump 5 while the stirring blade 7 rotates during the storage. Preventing solid components such as impurities from settling and depositing in the tank 4, there is no inconvenience of significantly contaminating the deep water storage tank 4, and it can be supplied to the next processing step in an unprocessed state. Next, in the coarse filtration tank 8, impurities,
Solid matter having a relatively large particle size such as dust can be mechanically removed by various filters. Next, desalination tank 9
, Where, for example, by the action of a reverse osmosis membrane, seawater can be converted into pure water and made drinkable. In this state, it becomes pure water that can be drunk, but further contains bacteria and the like, so that it is continuously led to the ozone contact tank 11 for sterilization treatment, and is transferred to the activated carbon filtration tank 12 for final deodorization and decolorization. By performing the treatment, desalinated deep sea water can be obtained as a product. According to the present invention, since the entire system can be systemized and unitized, the unused land of the coast facing the sea from which deep seawater of 200 m or more can be collected can be utilized. , Can be provided at very low cost,
The resulting desalinated mineral water and nutrient-rich deep water can be inexpensively provided for various uses as well as for drinking.
