DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an underwater floating body for improving the water quality of ponds, swamps, lakes and the like having a relatively shallow depth, and a method of improving the water quality using the floating body. .

[0002]

2. Description of the Related Art Conventionally, as a method of improving water quality of ponds, swamps, lakes, and the like, a method using an intermittent air pump is well known. This intermittent air pump is a cylindrical device with an air chamber with a float on the upper part and an inverted siphon on the lower or middle part. When air is sent from the compressor to the air chamber, the air gradually accumulates in the air chamber, and when it reaches the lower end of the siphon, the reverse siphon works and the air in the room is blown into the cylinder at once. Then, it rises in the cylinder as bullet-shaped bubbles and pushes up the water in the cylinder, and the bubbles separated from the upper end of the cylinder gradually expand into a donut shape and blow up to the water surface with the water of the rising path It is configured as follows.

[0003] The cold bottom water pumped as described above is mixed with the surface water containing a large amount of oxygen at a high temperature to give oxygen, and at the same time the water temperature rises and becomes light. It diffuses in the horizontal direction without returning, and as the bubbles rise, the bottom water newly flows into the cylinder from below to create an upward flow. When bubbles are ejected intermittently at intervals of 10 to 20 seconds in this way, the bottom water rises → mixes with the surface water → diffusion in the horizontal direction occurs repeatedly, so that the water in all layers eventually mixes and circulates As a result, the algae plankton decreases, and the repetition of water circulation causes the algae that have moved from the bright surface to the bottom to weaken and have no adverse effect on water quality.

However, the above-mentioned conventional method is suitable for improving the water quality of ponds, marshes and lakes where the depth is deep and a dark bottom layer where light does not reach is present, but it is effective at shallow places where the average water depth is 5 m or less. Since it cannot be obtained, and the cost of the intermittent air pumping system is expensive, it cannot be said that it is suitable for improving the water quality of shallow ponds and lakes in view of cost.

[0005]

DISCLOSURE OF THE INVENTION In view of the above-mentioned prior art, the present invention relates to an underwater floating body for water quality improvement suitable for use in improving the water quality of a relatively shallow pond, swamp, lake, and the like.

In addition, the reason why the contact member was woven with a copper wire or a bactericidal effect equivalent to the copper wire and made into a brush shape was to prevent the adhesion of unnecessary bacteria by the bactericidal effect and to increase the contact area with water. is there. Also, a weight that is lighter than the weight for fixing described above is attached to the lower part of the contact member,
The contact member may hang straight down.

On the other hand, in the method for improving water quality using the above floating bodies, an appropriate number of the water floating bodies for improving water quality may be grouped, and the periphery thereof may be surrounded by a net or the like to prevent contact with other groups. The effect is further improved. The installation area of the water suspension for water quality improvement is 1% of the total surface area of ponds, swamps, lakes, etc.
It is desirable to set the area not to exceed / 3. this is,
Ponds, swamps, lakes, etc. can be installed to about 1/3 of the area to block the light transmitted through the water and suppress the generation of bacteria, but above that, the sunshine is hindered and effective algae are killed. This is because there is a danger of causing it to occur.
