DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for breeding and breeding shellfish accompanying the promotion of growth of useful seaweeds, and a seawater purifying apparatus used for the method.

[0002]

2. Description of the Related Art In recent years, the growth of useful seaweeds on the seashore has deteriorated with the progress of marine pollution. Therefore, the breeding and breeding of shellfish such as abalone and sea bream that feed on these useful seaweeds. Is inhibited. For example, kelp and alame,
Iso-bake phenomena occur in places where useful seaweeds such as scutellum or tengusa and funori grow, causing great damage, and it takes several years to recover them. It has become widespread and has become an obstacle to the growth of useful seaweeds. Therefore, it is difficult to collect shellfish and the like, which threatens the lives of fishermen.

Many techniques have been developed and proposed as measures against these marine pollutions, but there are advantages and disadvantages, and the development of more effective techniques is currently awaited.

[0004]

SUMMARY OF THE INVENTION The present invention relates to a method for purifying contaminated seawater in a predetermined sea area, promoting the growth of useful seaweeds, and cultivating and breeding shellfish which feed on these seawater, and a seawater used therefor. A purifying device is proposed.

[0005]

SUMMARY OF THE INVENTION The present invention provides a ceramic material having a function of filtering and purifying contaminated seawater, a so-called filter overpowering effect, and a magnetic material having a function of collecting shellfish (that is, a biological substance having a magnetic effect). Has a habit of sensing and gathering).

That is, the first invention is useful for purifying contaminated seawater by laying a seawater purifying device constituted by combining a ceramic material and a magnetic material formed into a predetermined shape on the seabed in a predetermined coastal sea area. A method of breeding and breeding shellfish accompanying the promotion of growth of useful seaweeds, characterized by breeding and breeding shellfish by promoting the growth of seaweeds. A plurality of ceramic plates are arranged side by side at a slight interval from each other so that the respective plate surfaces are parallel to each other and fixed in a box form, and a piece of magnetic material is placed between every several ceramic plates in the box form. The present invention provides a seawater purification apparatus characterized by attaching a seawater purifier.

In the first and second aspects of the present invention, it is preferable that the ceramic material has an overactive effect and is formed into a plate shape, and the magnetic material is a ferrite magnet having a shell collecting function. is there.

Further, in the first aspect of the present invention, it is preferable that the seawater purifying device is installed so that the surface of the ceramic plate is perpendicular to or close to the flowing direction of the seawater.

Next, the present invention will be described in detail. The tile-shaped porcelain plate used in the present invention is made of a porous material which is made of a predetermined mixture of raw materials such as porcelain clay, porcelain clay, clay and the like, formed into a predetermined plate shape, and then fired and fired. It is a porcelain plate that has excellent durability such as corrosion resistance, seawater resistance and weather resistance. I found that there was. Although the reason is not clear, it is considered that contaminated seawater is purified by the filter effect by the myriad of fine pores of the ceramics and other reasons.

[0010] Of the ceramic tiles, those of the magnetic and sessile natures have the overeffect. In addition, it is more effective that the surface of the ceramic plate used in the present invention is not smooth and has some irregularities such as grooves. If the potency deteriorates due to clogging of the ceramic plate, etc., pull it up to the sea or wash it with a surface regenerating device such as an underwater structure using a water jet on the sea floor, and regenerate it, and use it semipermanently. Can be used for

Next, as magnetic materials, soft magnetic materials (supermalloy, carbonyl iron, silicon iron, permalloy, etc.), permanent magnets (KS steel, carbon copper, OP magnets, etc.), and sintered magnets (permanent magnet powder) are used. However, as a result of various studies, it has been found that a ferrite-based magnet having a high coercive force is most suitable as the magnetic material used in the present invention from the viewpoint of the shell collecting function.

A ferrite magnet is generally expressed by MO
This is a sintered magnetic material represented by Fe ₂ O ₃ , wherein M is a divalent metal ion such as Mn, Mg,
There are Cu, Ni, Co, Zn, Cd, Ba and the like. This ferrite magnet is classified into soft and hard.
O. A hard magnetic material represented by 6Fe ₂ O ₃ is most suitable.

A plurality of ceramic plates having substantially the same shape and the same size as described above are arranged side by side at a slight distance from each other so that their surfaces are parallel to each other, and fixed in a box form. Then, a ferrite magnet piece formed into an appropriate size is attached and fixed between every several ceramic plates in the box form so as not to reduce the effect of the ceramic plate.

There are various methods for attaching the ferrite magnet piece to the square frame. For example, a through hole is provided in the center of the ferrite magnet piece, a U-shaped iron bar is made to penetrate, and the ferrite magnet piece is fixed with a fixing bracket. The iron bar is supported and fixed, and is fixed to the two iron frames on the upper side of the rectangular form by bolts provided at both ends of the iron bar. In the case of a set of ten ceramic plates, there are in principle three ferrite magnet pieces.

A number of large, medium and small seawater purifiers made of the ceramic plate and magnetic material pieces manufactured as described above are manufactured, and all of them are placed on the seabed in a predetermined sea area along the coast. It is assembled so as to be perpendicular to or close to the direction of seawater flow, connected to each other by bolts or chains, and constructed and submerged so as not to be washed away by the ocean current.

[0016] By performing the above, the seawater in a predetermined sea area is purified by the over-effect of the ceramic plate, the marine environment is purified, and the growth of useful seaweeds serving as baits for shellfish such as abalones and sardines. It is promoted.

Furthermore, the shellfish collects by sensing the magnetism by the shellfish collecting function of the magnetic material attached to the seawater purifying apparatus, and is grown with the useful seaweed as bait, so that the useful shellfish can be efficiently collected. It is.

After the contaminated rock surface, for example, the rocky rock surface of the coastal area, is regenerated by the technology described in Japanese Patent Publication Nos. 4-71595 and 5-11, the technology of the present invention is applied. By doing so, the effect is further improved. Next, examples of the present invention will be described.

In this case, the shape of the magnetic material piece 2 may be any shape such as a square shape or a circular shape, but it is important that the magnetic material piece 2 is attached so that the potency of the ceramic plate 1 is not deteriorated.

In addition to the above, the ceramic plate 1 is, for example, 180
mm × 180mm × 12mm
A large number of box-type purification devices using ceramic plates 1 of various dimensions, such as one set of schools, are produced according to the condition of a predetermined seabed where the water is to be laid. In this case, the surface of the ceramic plate 1 of each purifier is set to be substantially perpendicular to the direction of seawater flow, and box-type purifiers of various sizes are arranged on a predetermined seabed in combination of large, medium and small as planned. They are connected to each other by bolts or chains and laminated or arranged side by side, so that they are constructed not to be washed away by ocean currents.
