Detailed Description of the Invention

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to water purification and erosion of rivers, lakes and marshes, closed areas, seas and the like, and sea reef blocks made of marine earth concrete.

[Prior Art] In recent years, water pollution has become serious in conventional ponds, rivers, lakes, closed areas, the sea and the like. The causes of these are mainly run-off of organic fertilizer and domestic wastewater and factory wastewater. Conventionally, sea-bottom improver Marine Earth Concrete is often used for revetment work, erosion blocks, fish reef blocks, etc., but it is known that this sea-bottom improver Marine Earth Concrete has some water purification effect. There is. By utilizing the electrode magnetic pole effect of the seabed improving agent Marine Earth concrete member, microorganisms are attracted to cause the microorganisms and animals and plants to live in the voids of the Marine Earth concrete to purify the water quality.
In recent years, there are blocks that also serve as water purification and biological breeding blocks that utilize the action of such a seafloor improving agent, marine earth concrete. In addition, a block having a water purification function in addition to a revetment and bed protection function has been proposed, but the block has a water flow channel consisting of vertical holes.
The block body was vertically penetrated, and a water flow passage was formed laterally from the vertical hole. When the block having such a configuration is installed, for example, on a riverbed, the river water flowing into the vertical holes and the horizontal holes through the structure is agitated in the vertical holes and exploded. By repeating this continuously, the amount of dissolved oxygen in water was increased, the action of microorganisms in water was activated, and it was intended to contribute to water purification.

[Problems to be Solved by the Invention] In the case of purifying water quality by using a seawall, a seawall, an erosion and a fish reef block, since the block strength is required, the whole block is solid. Since it is made of concrete, some microorganisms that contribute to water purification can only reproduce inside the holes, and that alone is insufficient from the viewpoint of water purification and conservation of the aquatic ecosystem. In order to perform better water purification, erosion, and reproductive action, more block inputs were required. In addition, the river water that flows into the vertical and horizontal holes
Although it was agitated and bombed in the vertical holes, the running water from the vertical holes and horizontal holes was insufficient in terms of water purification and conservation of the aquatic ecosystem.

[Means for Solving the Problems] Therefore, the present invention was developed to solve each problem in concrete blocks, and provides a water quality purification block capable of exerting its durability of an efficient purification function. And for the purpose of reproductive blocks, for the purpose of providing a seawall and civil engineering blocks with excellent durability using concrete blocks, the sea bottom modifier Marine Earth concrete body, fly ash of coal ash, plaster, Ash, ceramic powder,
Titanium oxide, titanium sponge, zeolite, iron powder, copper,
Aluminum, carbide, charcoal, water, magnetic metal, iron oxide, clay,
A mixture material containing either salt or caustic soda is sprinkled with fibrous cloth and cotton or sponge to adsorb rice husks and wood chips, and the mixture is burned. A porous molded article is attached, and oils and heavy metals are adsorbents. It is characterized by the integration of reproductive animals and plants.
In addition, a water flow adjusting plate is attached to the horizontal hole, and the river water and the tidal current flowing into the horizontal hole are directed in the upward flow direction, and a pursuit flow is generated in the central portion of the vertical hole to purify water.

The seabed modifier Marine Earth Concrete is
It is a concrete of a magnetic material and a porous material manufactured by adjusting the mixing ratio of coarse aggregate to fine aggregate as compared with ordinary concrete. Phosphorus, ammonia, nitrogen and other heavy metals and oils, fats and oils are used as adsorbents for reproduction animals and plants. Mainly fly ash of coal ash, ceramic powder, titanium oxide are adsorbed on a sponge of porous body and burned. It is a thing. These have a large filtration function and adsorption, and a large water-retaining and penetrating action, and by using an excellent porous adsorbent in combination with the seabed improving agent Marine Earth Concrete, a large water purification action and effect can be obtained. . It is also possible to attach and use the through hole and the flowing water channel according to the purpose of use. Of course, it should be adjusted depending on the type of heavy metal and the polluted water quality.

There is no limitation on the shape of the block and the place of use, and the shape can be freely selected according to the purpose of use. For example, it can be installed in the riverbed of rivers and revetments, drainage channels for root consolidation or erosion and reproduction blocks, fish reef blocks, wave-eliminating blocks, erosion blocks, water purification blocks, etc. in or near water.

[Action] The main causes of water pollution are general domestic drainage and field fertilizers and pesticides. Types include organic nitrogen oxides and organic phosphorus. Regarding the water purification, the magnetic and magnetic poles in the seabed improver Marine Earth Concrete and the organic system and organic matter in the polluted water are carbon dioxide and carbon dioxide due to the action of the microorganisms that reproduce in the numerous holes. It was found that water and nitrogen compounds are actively decomposed and removed into nitrogen gas and hydrogen gas, respectively, but the removal action of phosphorus, nitrogen and ammonia and the action of running water by only the seabed improving agent Marine Earth are small. .

[0008] FIG. 1 shows the case where the seabed improving agent Marine Earth Concrete alone (2) and the seabed improving agent Marine Earth Concrete is used in combination with phosphorus, ammonia, nitrogen, oil fat and heavy metal adsorption (1), phosphorus and nitrogen in water, Reduce the ammonia concentration.

When the mass of the fired porous body molding is attached and detached, it has permeability and filterability, and after adsorption filtration of sewage, heavy metals, fats and oils, when the adsorption function decreases, the porous body molding is performed. It becomes possible to exchange the lumps and continue the effect.
