The present invention relates to a structure of an artificial aquatic island that is installed for the purpose of water purification on the surface of rivers, dams, ponds, lakes, rivers, etc. More specifically, the water quality purification by effectively absorbing and concentrating nitrogen and phosphorus components in the water It relates to the structure of artificial aquatic islands to improve the function and to help the smooth growth of aquatic plants.

As awareness of environmental pollution continues to grow day by day, many researchers continue to work to resolve water pollution in rivers, lakes, and rivers. Pollutants such as rivers, rivers and lakes include pollutants such as livestock waste from livestock houses, domestic sewage, pesticides flowing from farmland and fertilizers, which cause eutrophication of the appeal. Eutrophication refers to a phenomenon in which algae or plankton grow abnormally due to excessive nutrients in rivers due to decomposition of organic matter by microorganisms. Since eutrophication destroys ecosystems of rivers and lakes, killing all living organisms in fresh water, several methods have been tried to prevent eutrophication.

Several methods of water quality improvement are widely known, such as agglomeration or precipitation of contaminants in water using disinfectant and flocculant.Physical and chemical methods are used to pressurize pollutants to the water surface. There is a method of flotation. In addition, a method of improving water quality such as sewage using microorganisms is also widely used.

Recently, in addition to the various water purification methods described above, water purification methods using aquatic plants have attracted the attention of researchers. If nutrients are absorbed through the roots of aquatic plants, such as moon roots, babies, copper herbs, silver grass, and reeds, it will prevent eutrophication of lakes and streams.

The water purification method using aquatic plants shows the effect of improving water quality by preventing eutrophication by ingesting nitrogen and phosphorus in aquatic plants, and the stem part of aquatic plants plays a role of blocking light energy permeation into water. Suppresses excessive breeding. By forming aquatic islands composed of aquatic plants, it is possible to secure habitats and habitats for aquatic insects, birds, and fishes, so that they can prey on aquatic algae to prevent excessive reproduction of algae. Thus, the purpose of water purification of the lake can be achieved in an eco-friendly way, and by creating aquatic islands where the aquatic plants grow, they can also perform beautiful functions as ecological parks.

Conventional techniques related to artificial aquatic islands are disclosed in Patent Publication No. 1997-65423, Utility Model No. 20-202650, Utility Model No. 20-255250, Patent Publication No. 2003-86379 and the like.

However, the published patents or utility models have a disadvantage in that they do not effectively concentrate eutrophication agents such as nitrogen or phosphorus in water. In particular, during the winter dry season, when the water quality deteriorates, the water plants cannot grow smoothly due to low water temperature and temperature, so that the adsorption of nutrients and the growth activity using the same are temporarily stopped.

In addition, the Utility Model No. 211901 is a mixture of loess and blowing agent at a high temperature of 1,000 ℃ or more to produce ocher granules, and then the ocher granules prepared by the above method is secondly heated at 600 ℃ again to be integrally structured. Disclosed is to create a loess vegetation base. However, this design has the disadvantage of excessive cost because the process of manufacturing the ocher structure is complicated and the high temperature treatment is required. In addition, the ocher structure has a swell or typhoon when multiple ocher structures are connected to form a wide artificial bankruptcy. In case of hitting the ocher structures due to rain and wind, a problem occurs that is easily broken. Therefore, it is difficult to apply it to dams or large-scale appeals.

Therefore, an object of the present invention is to provide a structure of a water purification system for water purification that can more effectively remove nitrogen and phosphorus, which are the causes of eutrophication of rivers and lakes.

In addition, an object of the present invention is to provide a water purification plant for water purification that effectively removes contaminants even when water quality deteriorates, such as a dry season.

In addition, an object of the present invention is to provide an artificial myelin sheath, which is applicable to a conventional artificial myelin sheath, to increase water purification efficiency.

In addition, an object of the present invention is to provide an artificial myelin sheath that is capable of performing water purification without being easily damaged even in a bad weather condition.

In order to achieve the above object, the present inventors have a multi-layered mesh in a conventional artificial aquatic island structure composed of a float, a support frame made of an outer frame and a wire mesh, and a reticulated pad for supporting and rooting aquatic plants. The invention has led to the development of a water purification system for water purification in which a tubular, granular or powdery char or elvan layer with high porosity is formed between a fiber support layer such as a pad or a palm fiber mat or cashmere.

By supplying concentrated nitrogen, phosphorus, etc. to the roots of aquatic plants, they can be very helpful in growing and removing pollutants. Porous adsorbents such as charcoal have a wide surface area and can simultaneously play a role as a media for the microorganisms for water purification, so there is no need to install a separate microbial contact media. Porous adsorbents, such as charcoal, are preferred for adsorption and concentration of nutrients in water and for functioning as microbial mediators, since selecting a granule with a small particle size can maximize the surface area.

Adsorbents, such as charcoal, are placed in tight mesh or loose fibrous mat pockets and placed between the top of the base, the top, the bottom of the reticulated pad, or several layers of reticulated pad.
