DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention
It has an excellent effect in terms of improving dissolved oxygen and microbial treatment of organic matter on the water bottom side, and is excellent in improving a large amount of water so that there is no comparable technology. However, there are many points for future research regarding the high level of cleansing of a relatively small amount of water (for example, several tons to several hundreds of tons). As for the fresh water using microorganisms, the one using a honeycomb is known, and although it shows a certain effect in the wastewater treatment, there is no sufficient fresh water for a large water tank, a pond or the like.

On the other hand, various types of water purifiers for household use have been proposed, but all of them are intended to achieve the purpose by passing them once, and have a different treatment concept from that of circulating fresh water.

[0005]

SUMMARY OF THE INVENTION However, according to the present invention, the deep water is circulated and circulated by performing deep infrared ray sterilization and microbial treatment while depositing fine water bubbles in inhalation water by depositing in the sterilized water area. It solved the conventional problem.

However, since the materials used in the present invention are air, far-infrared radiation substances and microorganisms, there is no fear of causing secondary pollution, and the power used is only the submersible pump and the air pump. On the other hand, there is an advantage that the risk of failure is extremely low. By using a fluid jet (pressurizing water or air) instead of the submersible pump, there is no solid moving in water,
There will be no breakdown.

That is, according to the present invention, a water-air mixture obtained by mixing fine bubbles with water to be brewed is pressurized and blown into the basin of water, and then the mixture is passed through a far infrared radiation region, It is a method of rectifying water in a closed water area, which is characterized by circulating water in the chilled water area after passing through the microbial water area. In another invention, a swirling force is applied to a mixture of air and water to blow it into a fresh water region, and the far infrared radiation region is a layer of far infrared balls or a far infrared porous layer. Next, the invention of the product is to combine the suction means of water to be sterilized, the means for blowing fine bubbles into the water, the far-infrared sterilization means, and the microbial treatment means in a device for circulatory sterilization by sinking into a sterilized closed water area A water discharge device for a closed water region, which is characterized by: a suction means for water to be scavenged; a means for blowing fine bubbles into the water. A freshwater device for a closed water area, characterized by combining a freshwater device combining far-infrared rectifying means and microbial treatment means, and a fountain device combining a fountain means with an underwater pump equipped with an underwater suspension means. is there. Still another invention is an apparatus for submerging into a water-cooled closed area and circulating and circumventing, by installing a submersible pump on a pedestal, providing a screen at the suction pipe end of the submersible pump, and a gas-water mixer to the discharge pipe. Provided, the discharge pipe end is tangentially inserted and opened to the lower part of the water tank on the pedestal, and the lower part of the water tank serves as a blowing chamber for the gas-water mixture, and the far infrared ray conversion layer is formed on the upper part of the blowing chamber. It is a fresh water device in a closed water region, characterized in that a microbial treatment layer is provided on the far infrared ray decontamination layer, wherein the air / water mixer is provided with an air diffuser on one side of the discharge pipe. A pressurized air chamber is provided outside the air board,
An air supply hose is connected to the pressurized air chamber.

According to the present invention, harmful chemical substances can be decomposed and water quality can be improved by the far infrared ray sterilization treatment, and organic solid matter contained in water can be treated by the microbial treatment. Therefore, the water quality of the treated water is rapidly improved, and the transparency can be significantly improved.

The water absorption capacity in the present invention is appropriately determined according to the amount of water in the water purification area, the purpose of water purification, the quality of the inflow water, and the like. For example, in the case of only rainwater inflow (no domestic effluent inflow), such as in a pond in a park, the capacity that can pass all the water in one month is sufficient, and when the domestic effluent inflow (the ratio of the inflow rate is Depending on the amount of water), the capacity should be such that all water can pass in 5 to 10 days. Specifically, if an inhalation pump of 10 m ³ is used for 1 hour, it will be 240 m ³ in 1 day and 240 in ³ days.
It will be 0 m ³ .

In the present invention, since fine air bubbles (for example, pressure release from a diffuser having a pore diameter of 1 mm or less) are mixed with water, not only the efficiency of dissolving oxygen in the air bubbles is improved but also a cleaning action is obtained. Yes, it has the effect of shaping far-infrared radiation (sphere or mesh). Therefore, there is no need for cleaning for a long period of time. The microbial treatment layer is formed by implanting aerobic microorganisms on pellet-like, porous small spheres or other microbial carriers having a large surface area. In an outdoor pond or the like, if only a microbial bed is provided and operated, the microorganisms will spontaneously implant during the operation, and after 1 to 2 weeks have passed, the sterilization ability will be exhibited.

[0011]

According to the present invention, a mixture of water and fine air bubbles is introduced under pressure, and the mixture is passed through the far infrared ray contaminated layer and the microbial treatment layer, so that harmful gas and organic solid matter are treated and efficiency is improved. I can clean water well.

[0014]

[Example 2] In order to install on the water bottom 2 of the pond 1, a bottomed cylinder 4 is installed on a pedestal 3, and an underwater pump 5 is installed on the outside thereof. A mesh screen 7 is connected to the tip of the suction pipe 6 of the submersible pump 5, and the tip of the discharge pipe 8 of the submersible pump 5 is tangentially inserted into the cylinder 4 and opened to the insertion portion of the discharge pipe 8. A steam mixer 9 is attached. In the air / water mixer 9, the cover 10 is divided into an air diffuser 11 and an air chamber 12, and an air supply hose 13 for pressurized air is connected to the air chamber 12. The air diffuser plate 11 is an inorganic plate having an infinite number of fine continuous pores (diameter of 1 mm or less), and diffuses the fine air bubbles 14 into the discharge water. The lower part of the cylinder 4 is connected to a mixing chamber 15, and a far infrared ray conversion layer 17 is provided on the mixing chamber 15 via a mesh plate 16 and a microbial treatment layer 19 is provided thereon via a mesh plate 18. There is. The far-infrared ray conversion layer 17 is formed by filling large and small far-infrared balls (5 mm to 10 mm), and the microbial treatment layer 19 is formed by accumulating micropore pellets 20.
In the figure, 21 is a screen cylinder screen mount, 22 is a mesh plate, and 23 is an electric wire cord.

In the above embodiment, when the submersible pump 5 is started and pressurized air is supplied through the air supply hose 13 as indicated by the arrow 24, the water at the bottom 2 of the pond 1 is transferred to the screen cylinder screen 7. It is inhaled as shown by the arrow 25, enters the submersible pump 5 through the suction pipe 6, and is discharged as shown by the arrow 26 from the discharge pipe 8. On the other hand, the pressurized air supplied from the air supply hose 13 is discharged from the air chamber 12 into the discharge pipe 8 through the air diffuser 11 and is blown out into the mixing chamber 15 together with the water in the discharge pipe 8. In this case, since the tip end side of the discharge pipe 8 is inserted into the cylinder 4 from the tangential direction, the mixture of air and water is indicated by the arrow 2.
It moves as a swirling flow like 7, 28. Then, the inorganic solid matter (for example, sand) is subjected to centrifugal force, separated into the cylindrical wall side, and descends along the cylindrical wall. On the other hand, the air-water mixture rises as shown by the arrow 29 and passes through the far infrared ray conversion layer 17,
Receives far-infrared water and sterilization. Then, as shown by the arrow 30, while passing through the microorganism treatment layer 19, the organic solid matter is decomposed by the treatment of microorganisms (for example, about 30% of treatment can be performed by one passage). The microbial treatment layer 1
The air-water mixture passing through 9 rises as indicated by arrow 31 (increases due to the pressurizing effect and the buoyancy of fine bubbles), and diffuses radially as indicated by arrows 32 and 32. Although the temperature of the air-water mixture in this case varies depending on the water depth, since the water temperature on the water bottom side is usually low, the temperature of the air-water mixture drops while diffusing. The water descended in this way is sucked again, so that it is eventually circulated.

Since the diffusion distance in the above is relatively short (for example, a radius of 10 m to 20 m), the interval between the cylinder 4 and the mesh tube screen is adjusted, or the installation position of the mesh tube screen is changed or a plurality of mesh screens are installed. Alternatively, it is necessary to move all the devices at regular intervals or arrange a plurality of devices appropriately. When the device of the present invention is used properly, it can exhibit the potting ability suitable for drinking.

A submersible pump 34 is suspended by a float 33 in the vicinity of the water surface of FIG.
