2. Description of the Related Art Conventionally, as a method for purifying water quality and forming seaweed beds in rivers and oceans, one of the methods is to lay a porous and permeable concrete block on the river bottom and the seabed and The voids according to the structure were used for filtration, or charcoal with fine voids was also packed in a bag and sunk to remove harmful substances such as organic mercury under water. In addition, it is known that artificial reefs are made by depositing a plurality of industrial waste materials such as glassy waste materials, slags, stone waste materials, etc. as aggregates and using various shapes of concrete lumber with many internal spaces. There is.

Further, the artificial seaweed bed is a strong structure which is not easily destroyed by the flow velocity and the waves, and its shape is a plane shape or a cross shape, a plate-like shape body having a through hole formed at the center, and a rectangular skeleton. There are shaped bodies, shaped bodies in which voids are provided between upper and lower disc-shaped bodies, and such various structures are known to be stacked vertically and horizontally and in multiple stages.

[0004]

However, in a water-permeable concrete block, since the size of the voids, which is the structure of the water-permeable concrete block, cannot be arbitrarily determined, the water permeability of the water-permeable concrete block deteriorates and it becomes contaminated. Unable to filter material,
On the contrary, when it is large, there is a problem that the substance to be filtered passes through and the permeable concrete block cannot remove harmful substances such as organic mercury, nitrogen, ammonia and phosphorus. Further, water purification using charcoal or the like has a problem that harmful substances and the like enter fine pores of the charcoal and block the pores, so that the water purification cannot continuously function.

Further, artificial reefs made by using industrial waste materials such as glassy waste materials, slags, stone waste materials, etc. as aggregates and arranging a plurality of various shapes using concrete lumber with a large number of internal spaces are respectively There is a problem in that it is very time-consuming and costly to sort the industrial waste materials according to the type, and cannot be easily commercialized. Further, if the waste cannot be completely separated and other waste materials are mixed in, there is a possibility that problems such as deterioration of water quality and secondary pollution may occur. The object of the present invention is the efficacy of microbial growth action due to the porous structure of pottery and ceramics, the activation of seafood by magnetism, the microbial attachment action of carbon fiber materials, and the microbial growth in conduits by sawdust and sawdust. An object of the present invention is to provide a seaweed bed growth device by water purification, which purifies water quality by utilizing the principle and enables growth and overgrowth of algae.

[0006]

According to the present invention, a seaweed bed formed into a cylindrical body or a polygonal cylinder body, which is made of a porous ceramic material or a ceramic material, which has an effect on the purification action of fresh water and seawater, is used as a base material. In the growing device, the cylinders are stacked and fixed in a plurality of stages vertically and horizontally, and are fixed in a relatively calm river bottom area and inland sea bottom area and lake bottom area to promote purification of contaminated fresh water and sea water. The spores of algal bodies adhere to and grow on the seaweed bed growth device having a cylindrical body and a polygonal cylindrical body that are stacked in a staggered manner.

Further, in a seaweed bed growing apparatus formed of a plurality of cylinders and polygonal cylinders, carbon fiber materials of various shapes are fitted at arbitrary positions on the outer peripheral surface and the inner peripheral surface of the cylinders and polygonal cylinders. A carbon fiber material is contained in advance in the ceramic material and the ceramic material as well as the bonding and the fixing and the adhesion and the connection.

Further, in a seaweed bed growing apparatus formed of a plurality of cylinders and polygonal cylinders, various wood sawdust and sawdust are provided in the cylinders and the polygonal cylinders and between the cylinders and the polygonal cylinders. It has been locked and enclosed.

The cylindrical body and the polygonal cylindrical body made of the pottery material and the pottery material, which are the seaweed bed growing apparatus of the present invention, are formed to have the same shape, the same length and the same diameter. However, the present invention is not limited to this, for example, a configuration in which a plurality of cylindrical bodies having different sizes are formed and stacked vertically and horizontally, and the cylindrical bodies of the cylindrical body and the polygonal cylinder are partitioned into a plurality of independent space portions. May be formed. When the seaweed bed growth device formed in these shapes is submerged in the river bottom, the ocean bottom, and the lake bottom, it is different from when it is sunk as a single unit, and multiple cylinders and polygonal cylinders are stacked vertically and horizontally. By virtue of this configuration, the flow velocity of water and ocean current collides with the surface of each cylinder and flows into it, which weakens the flow velocity and causes stagnation, causing subtle changes and spores of algae floating underwater. Easy to attach.

The carbon fiber material and the wood sawdust, sawdust and the like according to the present invention are capable of removing chemical substances such as uric acid and nitric acid under water due to the purifying action of the carbon fiber material and the microbial growth action due to the porous structure. Decomposes to prevent oxidation and chemical change of organic substances under water, and improve water quality. In addition, the fine sawdust and sawdust that appears when processing wood is filled in a bag such as a water-permeable non-woven fabric or knitted fabric that does not allow the sawdust and sawdust to flow out of the bag. And, it is locked or enclosed in the polygonal cylinder body and between the cylindrical body and the polygonal cylinder body which are connected and fixed. Since the sawdust and sawdust form a fine conduit void, by the action of the microbial growth principle in the conduit, contaminated freshwater and seawater and lake water are removed by filtration and adsorption and synergistic effects, etc., Algae adhere to the bag body so that microorganisms can easily propagate, and the function for growing seaweed beds can be fully exerted.

The method of attaching the carbon fiber material in the present invention is as follows.
A through hole is provided at an arbitrary position on the outer peripheral surface and the inner peripheral surface of the cylindrical body, and a plurality of carbon fiber materials bound together are formed through the through hole, or a plurality of carbon fiber materials are provided in the recess. It is formed by fitting the bound end portions or fixing them with an adhesive. Further, it may be contained in the raw material such as porcelain clay and clay at a stage before forming the cylindrical body and the polygonal cylinder.

[0012] As described above, the purification effect by the microbial growth action due to the porous structure of the pottery and the ceramic material and the activation action of seafood, the microbial adhesion action of the carbon fiber material and the purification action by the propagation of the microorganisms and the wood Sawdust and sawdust promote the principle of microbial growth and adsorption in the conduit, and promote algal growth by adhering algae to the bag body, while small fish and shellfish live due to changes in the flow of water and ocean currents. As a result, small fish and large fish that feed on shellfish migrate, and a food chain is formed underwater, which has an extremely effective effect on the formation of seaweed beds in water.
