Conventionally, a method for purifying water quality such as a reservoir or freshwater lake is performed by using a chemical water purification facility or a waste water purification facility using chemical substances, which is economically burdened due to the enormous cost of purifying and maintaining the facility. This is large, there are problems such as side effects such as severe opposition of the residents and civilian environmental groups.

In addition, the conventional environmentally friendly artificial plant islands include the Republic of Korea Utility Model Registration Publication No. 20-0305137 and Patent Publication No. 2003-0017074, but the weak buoyancy or the structure forming the artificial islands and the plant growth and It is difficult to maintain / manage the artificial island to have a clean and beautiful view as the artificial island manager falls into the water or falls below the water when the artificial island manager climbs to the artificial island.

In addition, since the conventional islands have been focused on the formation of artificial vegetation based on natural vegetation, there is no consideration of changes in the aquatic ecosystems that occur under the islands due to the formation of artificial islands. There is a problem such as failing to supply the fresh air can not prevent water pollution due to the generation of suspended matter and sludge.

Conventional artificial islands are mostly rectangular or square in shape and supply boxes made of different sizes to order, purchase, and use boxes of the desired size, so it is not easy to modify its shape or size during work, and designed according to this There is a problem that the time and economic loss occurs because the landscape is not very good and the worker's work time is consumed a lot.

The problem to be solved by the present invention is to recognize the problems as described above and to create a sludge (sludge) accumulated in the lower portion of the artificial lake or general reservoir easy to water pollution due to the water is generally accumulated and eutrophication due to the inflow of organic matter The microbubble generator that generates oxygen-containing microbubbles deep in the water so as to prevent as much as possible, is located around the microbubble generator, blown to a desired size and shape while having a constant diameter as a raw material of high-density polyester Molded to prevent the outflow of air to maintain a high buoyancy at all times, the structure is located where workers can safely work on the artificial island when needed, and a grid-shaped support to support a variety of objects below the formed structure There is a structure that can be combined, The unit has a structure installed to achieve the desired size and shape by connecting each structure to each other, a mat made of a polyester-based having a root-shaped network structure is installed on the support, and the plant material on the mat The artificial cotton or artificial soil or natural cotton layer made of a synthetic resin series is located, and the mat and the artificial cotton, natural cotton or artificial soil layer are formed using a structure for connection formed on the structure made of the high-density polyester tube. It is composed of a fixed net, which allows free inflow of sunlight and fresh air between artificial islands and can achieve various sizes and shapes. The purpose is to achieve the method.

In addition, the present invention is the bubble generated in the microbubble generator located inside the structure with artificial myelin sheath very small size of 0.25mm and the pressure of the bubble is equal to or lower than the water pressure so that the bubble stays in the water for a long time without rising well above the water surface By supplying oxygen for BOD removal for a long time, it removes sludge accumulated at the bottom of artificial lake or general reservoir, prevents eutrophication due to inflow of organic matter, and also has a vegetation base composed of artificial cotton layer and has various sizes and structures. It is another object to prevent or minimize changes in the aquatic ecosystem by preventing the formation of sludge and floats by allowing the sun and fresh air to flow freely between the artificial islands formed.

The present invention is generally installed to plant a microbubble generator and plants that can prevent the sludge (sludge) accumulated in the lower portion of the artificial lake or the general reservoir and the eutrophication due to the inflow of organic matter is easy to water pollution due to the accumulation of water The present invention relates to an assembled artificial aquatic island having a microbubble generator having an environment-friendly configuration and a manufacturing method thereof. Conventional bubble generator is a system that uses compressed air to generate air bubbles by forcibly blowing compressed air into the water. Air bubbles are larger than 4mm in diameter and drifting rapidly on the water surface and staying in water (average tens of seconds). Soon, the oxygen transfer rate is very low, ranging from 10 to 12%. In addition, conventionally formed structures having weak buoyancy or artificial islands are formed with the focus on facilitating the growth of plants. When an artificial island manager climbs into an artificial island, it may fall into the water or descend below the artificial island. It was difficult to manage to keep the landscape clean and always in good condition, and there was no consideration of changes in the aquatic ecosystem under the island due to the shape of the island or the formation of artificial islands. There is a problem such as polluting the water quality by causing the generation of suspended solids due to not being distributed. The present invention has been made in consideration of the above-mentioned conventional problems, and looks at the construction means in more detail. The microbubble generator located inside the structures having artificial plants according to the present invention draws air in the atmosphere into a large diameter plastic tube instead of compressed air, and then has a small orifice tube (P ₁ V ₁ = P). ₂ V ₂ , temperature is constant), so the low pressure air flows into the water due to the vacuum effect generated when the air escapes into the water. When the air whose pressure is lowered is attached to the bottom of the microbubble generator and pushed into the water vortex generated by the fan rotating by the motor located on the surface of the water, the water gathers around the air where the pressure is lowered and the surface tension Due to the large number of micro bubbles generated, the average size of micro bubbles generated at this time is very small (0.25 mm), and the pressure of the bubbles is equal to or lower than the water pressure so that the bubbles do not rise well above the water surface and stay in the water for a long time. Demand) By supplying oxygen for a long time (about 10 to 12 hours), most of the oxygen in the bubble is dissolved in water. At this time, the oxygen transfer rate (BOD is oxidized and converted into CO ₂ and H ₂ O) corresponding to the percentage of oxygen used for BOD removal is very high at 98%. The generated oxygen removes sludge accumulated under the artificial lake or general reservoir or prevents eutrophication due to inflow of organic matter. The microbubble generator as described above is fixed to a floating device having a shape of a rectangular, square, oval or circular shape having a predetermined thickness and positioned on the water surface. In addition, the microbubble generator may be generated by using a commercially available flex pump capable of simultaneously inhaling fluid and inhaling air, and on one side of the pump, an inlet for sucking water from a reservoir and an air inlet on the other side of the pump. An air control valve is attached to inhale the air in the atmosphere, so that water and air are introduced into the water with a strong force to generate micro bubbles having a diameter of about 0.4 mm. The pump for generating microbubbles is fixed to a floating device of a predetermined size is located on the water surface. The microbubble generator is located adjacent to the fixed floating device, and blow molding to a desired size and shape with a high-density polyester as a raw material to form a structure having no long-term deformation and high buoyancy because there is no outflow of air. . The formed structure (1 in Figure 1) is formed by a process of blowing air into the tube after the mold to a predetermined size and shape, unlike the structure produced by the conventional fusion method used in the sun or air for a long time It is designed and manufactured with a high density polyester material that hardly deforms even when exposed. The structure made of a high-density polyester tube has a structure (grooves, etc.) that can be coupled to the grid-shaped support to support a variety of objects (mats, cotton, environmentally friendly plants to be planted) in the lower portion of the mold during or after the mold 1, 3) is formed, and on the upper portion, a constituent means (round ring shape) having a structure that connects and assembles structures made of a high-density polyester tube to each other to form an artificial island of a desired size and shape is installed. . A support that can support various objects for forming a myelin island using a structure (3 in FIG. 1) capable of coupling a support formed on the structure made of the high-density polyester tube is installed. The mat is made of a polyester-based material having a root-shaped network structure is installed on the installed support (Fig. 1 2), the artificial cotton, natural cotton or artificial made of synthetic resin series to enable the planting of plants on the mat Soil layer is formed. Artificial soil is made by foaming porous ceramics or resinous resins and making it porous, so its specific gravity is much lower than water, and its size is about 1mm to 30mm. The mat and artificial cotton, natural cotton or artificial soil layer is fixed by a structure and a mesh formed of the high-density polyester tube. The mesh for fixing the mat and artificial cotton, natural cotton or artificial soil layer is formed on the top of the structure formed of the high-density polyester tube to use a ring having a variety of shapes formed to connect and assemble the structures together or high density It is also possible to form and install a separate netting structure on the top of the structure formed of a polyester tube. The thickness, size and shape of the tube of the structure formed of the high-density polyester tube according to the present invention can be variously designed and manufactured in consideration of the size of the reservoir, the size of the buoyancy and the taste of the consumer. The structure for assembling the structures formed by the high-density polyester tube to each other is formed in a structure having a round circle, oval or a string or a ring on the top of the structure formed of the polyester tube to be connected to or tightly connected to each other . The connection between the formed connection or coupling structure is made by a relatively strong string (surface or synthetic resin series) or a structure having a constant length and connecting ring. The vegetation base agent according to the present invention is used to plant aquatic plants using artificial cotton or artificial soil or natural cotton prepared using synthetic resin-based materials, and the bottom of the artificial cotton, artificial soil or natural cotton layer The mat is made of a polyester-based mat having a root-shaped network structure is made of a structure that can root as much as possible in the water.
