Abstract

PURPOSE:To remove chlorine and the other harmful or unnecessary substance contained in water by diffusing extremely fine bubbles into water to be treated and also allowing infrared rays to act. CONSTITUTION:A floating water cylinder 2 is erected by a leg piece 5 in the central part of the inside of a water clarification tank 1. The inserted cylinder 7 of an air diffuser board 4 is fixed on a support plate 6 fixed to the lower part of the floating water cylinder 2. A network body 13 is horizontally spread in the upper part of the air diffuser board 4. Many spherical bodies 3 for generating far infrared rays are packed on the network body 13. Water is supplied into the water clarification tank 1 by opening a valve 18 and an air pump 11 is started and also the valve 18 is closed. Pressurized air passes through the air diffuser board 4 and ascends as fine bubbles and furthermore passes through the layer for generating far infrared rays. When bubbles ascend, water in the vicinity thereof inevitably ascends in the same direction and therefore water in the clarification tank starts convection. In such a way, since extremely fine bubbles are diffused in the water to be treated and also far infrared rays are allowed to act, chlorine, red rust, water-bloom and the other harmful or unnecessary substances dissolved in water or mixed therewith are removed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for irrigation for the purpose of successively irrigating and supplying water.

[0002]

2. Description of the Related Art Conventionally, an aeration method and an apparatus for brewing a large amount of water and an apparatus for using microorganisms are known, and an apparatus for using an adsorbent or for passing through a filtration layer for drinking water or the like. Was known.

[0003]

The aeration method and apparatus improve the dissolved oxygen content of large amounts of water in dams, lakes, swamps, etc.,
Although the microorganism treatment of the organic solids is remarkably effective, it cannot be expected to be effective enough for drinking to remove chlorine, trihalomethane, red rust, water-bloom, etc. for drinking.

In addition, there are some effects of considerable effects on the fresh water mainly using the adsorbent which has been widely used in recent years or the fresh water mainly composed of filtration, but the removal of chlorine, trihalomethane and the like is insufficient, and heavy metals In addition to the problem that the adsorbent cannot be removed, short-term replacement is necessary because the microorganisms adhere to and propagate on the adsorbent and cause problems, and the effect of the adsorbent is lost due to clogging and the like. There was a problem to do. Even when the filter layer is mainly used, the above problems such as clogging of the filter layer cannot be avoided.

[0005]

The present invention is capable of removing chlorine, trihalomethanes, heavy metals, red rust, blue-green algae, etc. at a significantly high rate by causing fine bubbles and far infrared rays to act, and at the same time, far infrared rays are generated by self-conditioning. It has succeeded in alleviating the above-mentioned conventional problems such as the fact that it is not necessary to replace the members, and the amount of dissolved oxygen can be improved, the pH can be adjusted, and hot water can be used.

That is, the method of the present invention is a fresh water method characterized in that far-infrared rays are allowed to act on the water to be treated while aerating ultrafine bubbles. Further, it is a fresh water method characterized in that water to be treated is made to flow between far-infrared ray generating members, and ultrafine bubbles diffused from fine pores are mixed into the flowing water. The flow of water to be treated next is generated by the diffusion of ultrafine bubbles.

In the apparatus of the present invention, an air diffuser having a myriad of fine holes is installed in the inner lower part of a fresh water tank having a water supply means and a water intake means. The water discharge device is characterized in that a far infrared ray generating member is installed above the air board. Further, the ultrafine pores are smaller than 100μ. Next, the air diffuser and the far-infrared ray generating member are installed in the same fresh water cylinder, and the fresh water cylinder is detachably installed in a fresh water tank having a water supply means and a water intake means. Is. Further, the far infrared ray generating member is a far infrared ray generating particle layer and a far infrared ray generating communication hole layer.

The size of the minute holes of the air diffuser in the above is
For example, 100μ or less, preferably 50μ or less is used, and 3
0 μ to 40 μ is preferable. The air pressure is usually 0.3 kg /
Use the cm ² position. The size of the particles in the far infrared ray generating member depends on the passage resistance, the contact time, etc.
5 mm spherical particles are mixed and used, but the shape is not necessarily limited to spherical. For example, crushed stones, coarse sands, nets, rods and the like are possible. Further, in the case of a honeycomb shape or a continuous communication hole, a hole diameter of about 2 mm to 5 mm is suitable.

The far-infrared ray generating member and the amount of fine bubbles are 1,800 cc / min, though it depends on the required water discharge capacity.
In the case of flushing water, a far infrared ray generating member of 1 kg (specific gravity 2.0 to 3.0) was used, and innumerable micro holes with an average diameter of 40 μ were used (for example, 100,000 pieces / 20 cm ² ) from an air diffuser. When 3,000 cc of minute bubbles were ejected, chlorine and heavy metals could be removed almost 100%.

In the above apparatus, since heavy metals and other protrusions adhere to the inner wall of the fresh water tank, it is preferable to wash with water once every one to three months. Regarding the pH adjustment, although slightly different depending on the pH of the raw water, for example, the raw water having a pH of 7.5 became PH 7.8 by passing through the fresh water tank of the present invention. It was also confirmed that the amount of dissolved oxygen was saturated.

There is no special relationship between the installation position of the far-infrared ray generating member and the installation position of the air diffuser, but the upper and lower positions are favorable in terms of convection generation.

The far-infrared ray generating through-hole layer of the present invention is
For example, a plastic wire woven body is intertwined in a mesh shape to form an infinite number of continuous holes having a diameter of 1 mm to 3 mm. After the holder is put in a plaster mold, the ceramic slurry is put into the mold and left for a certain period of time, and the ceramic slurry adheres to the surface of the holder. Then, remove the ceramic sludge that does not adhere (tilt the mold), remove the mold, dry it, and sinter through a process such as tsubaki-shiki (Japanese Patent Publication No. 1-2.
No. 3435), the far-infrared ray generating communication hole layer according to the present invention can be formed.

In addition to the above, if a plate-like material is formed from a mixture of ceramic sludge and combustible fibers and the plate-like material is fired to eliminate the combustible fibers, a porous ceramic disk can be formed.

Further, a foaming agent is mixed in the ceramic slurry,
By molding and solidifying and then firing, a continuous-hole molded product can be obtained.

[0015]

In the present invention, since far infrared rays and ultrafine bubbles act together, harmful substances such as chlorine, red rust, water-bloom and other heavy metals are removed or drastically reduced. It also improves PH and dissolved oxygen content. Further, since the far infrared ray generating member receives extremely fine bubbles, clogging and stains are prevented.
