CONSTITUTION:A stirrer 7 for stirring the inside of the water and injecting the ozone therein and UV sterilizing lamps 4 housed in light transmissive cylinders 3 are disposed to a supporting plate in the upper part of the body 1 of a cleaning up device. After the water is treated by the ozone and UV rays generated by the lamps 4, the water is passed through a filter tank 13 and is thereby treated. As a result, the sure decomposition of the various patho genic bacterium of the fishes and the org. material harmful to the fishes in the water, the removal of the dead algae of the water-blooms and the secretion of the fishes, the removal of the dust, etc., are permitted. in marshes, ponds etc.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to improvements in water purification devices for swamps, ponds, fish farms, etc.

[Conventional technology and its problems]

Conventionally, it has been widely practiced to keep ornamental fish and breeding fish in swamps, ponds, fish farms, etc.

By the way, in swamps and ponds, the water quality deteriorates due to environmental pollution, which hinders the growth of fish.In addition, when the water temperature rises in the summer and sunlight shines on the water surface, blue-green algae forms, making the water murky and making it difficult for ornamental fish to observe and admire breeding fish. prevent.

Conventionally, water from marshes and ponds is circulated by pumps and filters are installed in the circulating water path to remove debris.

However, according to a device that installs a filter in the water path, garbage can be physically filtered out, but various fish-pathogenic bacteria and organic matter harmful to fish contained in the water cannot be decomposed, and blue-green algae that appear in the summer cannot be sterilized. This has the drawback that fish growth is poor and the water becomes cloudy, making it difficult to observe fish.

Therefore, in the past, as another device, an ultraviolet germicidal lamp was installed inside a translucent cylinder in the water passage, and the water was irradiated with ultraviolet rays of 253.7 nm, and the ozone generated by the ultraviolet germicidal lamp was transferred to the air collection tube. Collected and injected into water, ultraviolet &'! 253.7r+m sterilizes various fish-pathogenic bacteria in the water, photo-oxidizes and decomposes organic matter on fish in the water, and sterilizes blue-green algae in the water.Ozone also sterilizes various fish-pathogenic bacteria in the water, Oxidative decomposition of nitrogen, iron, and organic matter is carried out.

However, according to this device, dead blue-green algae and fish secretions that have been sterilized by ultraviolet light enter the water, making the water cloudy and less transparent.

[Purpose of the invention]

The present invention was invented in view of the above points, and includes decomposition of various fish-pathogenic bacteria and organic matter harmful to fish in the water, sterilization of blue-green algae, and removal of dead blue-green algae and fish secretions in swamps, ponds, etc.
It is an object of the present invention to provide a water purification device that can reliably remove garbage.

[Means for solving problems]

The invention will now be explained with reference to the figures. In Figure 6, 1 is a box-shaped purifier main body, 2 is a water pipe provided on the side wall of the purifier main body 1, 3 is a translucent cylinder supported on the upper wall surface of the purifier main body 1, 4 is an ultraviolet germicidal lamp mounted inside the translucent cylinder 3; 5 is a hollow pipe supported on the mounting plate 6 of the translucent cylinder 3; It is located inside, and its upper end protrudes above the mounting plate 6.

7 is a stirring device supported on the upper wall surface, 8 is a stirring device 7
It is a hollow ventilation pipe that constitutes the pipe, and is made of, for example, stainless steel. Reference numeral 9 denotes a rotary blade rotatably provided at the lower end of the ventilation pipe 8, and is interlocked with a motor 11 by a support rod 10. Note that an aeration device may be provided in place of the stirring device. Reference numeral 12 denotes a communication pipe connected to the upper part of the ventilation pipe 8, which guides ozone generated from the ultraviolet germicidal lamp 4 to the tip through the ventilation pipe 8, and injects it into the water by rotating the rotary blade 9. It is composed of: 13 is a box-shaped filter body; 14 is a filter bed provided with a predetermined gap 15 inside the filter body 13, which has a large number of small holes, and is made of, for example, plastic. 16 is the filter bed 14
A plurality of filters are laminated on the top surface of the filter, and the filters are structured so that the filters are coarser from the bottom layer to the top layer. The filter is made of, for example, polyethylene resin and has a mat-like structure. Further, water treated with ultraviolet rays and ozone within the purification device main body 1 is sent into the filtration device main body 13 through the water pipe 2.

When the ultraviolet germicidal lamp 4 is turned on and the rotor blades 9 are rotated, water from a swamp or pond is pumped into the purifier main body 1 through a water inlet 18 provided on the side wall at one end of the purifier main body 1 by a pump 19. After being treated with ultraviolet rays and ozone, the water is sent to the filter main body 13 through the water pipe 2, and then sent to marshes and ponds.

〔Effect of the invention〕

With the water purification device according to the present invention, ultraviolet rays of 253.7n
When water is irradiated with m, it sterilizes various fish disease bacteria in the water, photo-oxidizes and decomposes organic matter harmful to fish in the water, and further sterilizes blue-green algae.

Furthermore, when ozone is injected into water, the strong oxidizing power of ozone kills various pathogenic bacteria such as Aeromonas, Vibrio, and Kodhwajira, and oxidizes and decomposes nitrite nitrogen, iron, and organic matter in the water. You can try to raise fish.

Furthermore, after being treated with ultraviolet rays and ozone, the water is sent to a filtration device, so dead algae and fish secretions that have been sterilized by ultraviolet rays are removed by the filtration device's filter, preventing swamps and ponds from becoming turbid. This has the advantage of improving the environment for observing fish.
