[0001] WATER PURIFYING DEVICE USING SOLAR GENERATING [0002]

The present invention relates to a water purification apparatus using solar power generation, and more particularly, to a water purification system using solar power generation, and more particularly, to a water purification system using solar power generation, which is installed in a place requiring purification of water such as a lake, a river, a reservoir, It is also possible to independently improve the quality of the water by using the generated power, and to spread the low-rise water raised by the low-rise water riser to a large area of the surface layer by using the low- The present invention relates to a water purification apparatus using solar power generation.

In the coastal oceans, lakes, rivers and reservoirs, eutrophication occurs due to excessive inflow and accumulation of organic matter. As a result, problems such as occurrence of green tide and red tide phenomenon, formation of anaerobic environment and disturbance of ecosystem are continuing.

Especially, in recent climate conditions, due to warming of temperature and temperature due to heat, red tides occur in the sea and green tides are generated in the river, causing damages to the industry such as the death of fish in farms.

To solve this problem, there have been proposed methods such as spraying loess at the site where the red tide is generated, but there is a problem that it is difficult to remove the red tide at a large area of the surface at a time, and a lot of manpower and cost are required.

Particularly, in the case of a caged fish farm in the sea, since it takes much time to remove red tides generated in a large area in the same manner as described above, fishes in a farm are frequently killed during the red tide control work .

In addition, methods such as clay spraying are not only a fundamental solution, but also lack a scientific basis, which requires a more radical and effective method.

Due to the above-mentioned problems, people operating a cage farm are used by providing an underwater aeration device at the bottom of the cage market in order to prevent red tide to some extent and obtain water quality improvement effect.

As a conventional technique for preventing red tide and improving water quality using the above-described water aeration apparatus, a regeneration utility model 20-0273347 (registered date: Apr. 12, 2002) "red tide countermeasure device" has been proposed.

The discharge valve discharges and diffuses the super-strength foam at the set pressure, The bubbles gradually dissolve in water and dissolve to increase dissolved oxygen in the water.

That is, according to the above-described prior art, air is supplied to the inside of the cage farm by injecting air at the bottom of the cage farm, thereby increasing dissolved oxygen in the water.

However, the above-mentioned prior art is disadvantageous in that only oxygen is supplied into the water, and water circulation or flow is not performed in the water, and the water quality improvement effect is insufficient.
