In the present invention, a slightly rough multi-porous material M is installed widely on the ground 1 of a sea lake, and a rough multi-porous material M is placed on the side facing the wave propagation direction in the width direction of the slightly rough multi-porous material M. A wave breaking stop a made of a porous material L is provided, and a wave breaking stop c made of a relatively high and relatively fine multi-void material N is provided on the other side in the width direction of the slightly rough multi-void material M, Between the breaking wave dam c and the breaking wave origin a, a slightly rough multi-porous material M with an appropriate width is exposed, and by using this as a breaking wave dam b and a purification breakwater, first of all, wave energy is can be used extremely effectively, and secondly, purification can be performed extremely well.
まず、波浪２が、あらい多空隙材Ｌよりなる砕
波起ａに当たることで、波浪２は、連続的な砕波

水中の溶存酸素の増加させることができ、次い
で、砕波３が、砕波止ｃと砕波起ａとの間にの砕
波溜ｂに溜められ、即ち、泡状になつたものが溜
められる。 First, when the wave 2 hits the breaking wave a made of the rough multi-porosity material L, the wave 2 becomes a continuous breaking wave 3, and this causes 〓exhaustion〓.
Dissolved oxygen in the water can be increased, and then the breaking waves 3 are stored in the breaking wave reservoir b between the breaking wave stop c and the breaking wave origin a, that is, the foam-like material is stored.
このような砕波３は、さらに、砕波止ｃに当た
ることで、エネルギーが消滅する如くに、一層細
かな泡状の砕波３となる。 When such a breaking wave 3 further hits a breaking wave stop c, the breaking wave 3 becomes even finer and foamy as the energy disappears.
このようにして、その砕波３のエネルギーは、
比較的細かい多空隙材Ｎ及びあらい多空隙材Ｌの

It permeates or infiltrates the voids of the relatively fine multi-porous material N and the coarse multi-porous material L, and can further increase dissolved oxygen in the water.
以上のように、波浪２のエネルギーを利用し、
砕波起ａ及び砕波止ｃにての、二重の砕波作用に
て、砕波効果を著しく高めることができる。 As mentioned above, using the energy of wave 2,
The wave-breaking effect can be significantly enhanced by the double wave-breaking action at the wave-breaking origin a and the wave-breaking end c.
このような砕波３にて、海湖の水域を浄化でき

果がある。 Such breaking waves 3 can purify (clean) the waters of seas and lakes, and at the same time, eliminate wave energy to protect coasts, etc., and prevent triangular waves caused by reflected waves, improving the safety of shipping routes. It has a useful effect.
その砕波３にての浄化作用について詳述する
と、砕波３にて、極めて効果的な〓ばつ気〓、〓接
触酸化〓等の作用を合理的に組み合わせたもの
が、本発明の浄化防波堤である。 To explain in detail the purification effect in the wave breaking 3, the purification breakwater of the present invention is a rational combination of extremely effective effects such as aeration and catalytic oxidation in the wave breaking 3. .
まず、〓ばつ気〓とは、水を空気中に撒布した

空気を溶解させることである。本発明では、波浪
２が、あらい多空隙材Ｌの砕波起ａや比較的細か

つ気作用が生じ、水中の溶存酸素を著しく増加さ
せることができる。 First of all, ``airing'' is the process of dissolving air in water by dispersing water into the air, mixing air into water, or stirring water to bring water into contact with air. That's true. In the present invention, when the waves 2 hit the breaking waves a of the rough multi-porous material L or the breaking waves c of the relatively fine multi-porous material N, the waves break 3 and cause an aeration effect, which significantly increases dissolved oxygen in the water. I can do it.
さらに、砕波３が砕波溜ｂに溜められること
で、砕波溜ｂの多空隙材内に浸透させて、水の活
性化を促進させることができる。 Furthermore, by storing the breaking waves 3 in the breaking wave basin b, it can be allowed to penetrate into the multi-porous material of the breaking wave basin b, thereby promoting water activation.

きる。 Catalytic oxidation is a phenomenon in which a biofilm is formed on the surface of an object when it comes into contact with contaminated water, and the sewage is oxidized and decomposed by this biofilm. In particular, the contact oxidation that occurs when water passes through the gravel is called inter-gravel contact oxidation.The wave breakers a, the breakers b, and the breakers c are all multi-porous materials, so the lake ebbs and flows. As the water passes through the wave breaking source a breaking wave basin b breaking wave stop c, this contact oxidation effect between gravels occurs and the water is purified. Specifically, the plankton and suspended solids that are pollutants in the water are removed from breaking waves.
Fish and shellfish bred in the multi-porous material of breaking wave pool b breaking wave stop c,
Contaminants in water can be removed by being absorbed or physically adsorbed by algae (biofilm).
また、以上のような働き（作用）等にによつ
て、水中の汚染物質のフロツク化も促進され、汚
染物質の沈降作用が進むものである。 Furthermore, the above-mentioned functions (actions) etc. also promote the formation of flocs of pollutants in the water, and the sedimentation action of the pollutants progresses.
さらに、浄化防波堤の背後の水域は、静止に近
い状態（静寂）とみることができ沈澱池が構成さ
れ、この箇所の汚染物は、沈澱作用にて浄化さ
れ、きれいな水となる。 Furthermore, the water area behind the purification breakwater can be considered to be in a near-still state (quiet), forming a settling pond, where pollutants are purified by sedimentation, resulting in clean water.
即ち、本発明のような浄化防波堤を通過した水
はきれいな水にできる。 That is, water that has passed through a purification breakwater like the one of the present invention can be made into clean water.
このように、自然の波浪２や、潮汐のエネルギ

から、維持費も殆ど不要であるし、薬品等による
二次公害の恐れも全くなく、安全な浄化防波堤を
提供できる大きな利点がある。 In this way, since it uses the energy of natural waves2 and tides and does not use any chemicals, there is almost no maintenance cost, and there is no fear of secondary pollution caused by chemicals, making it safe. This has the great advantage of providing a cleansing breakwater.
