Abstract

PURPOSE:To permit removal of various kinds of bacterium in water and algaecidation of water-blooms by providing a stirrer having an impeller to a supporting body and disposing UV sterilizing lamps housed in light transmis sive cylinders to the periphery of the stirrer in such a manner that the distances therebetween can be adjusted. CONSTITUTION:The stirrer 3 having the impeller 5 for stirring the water is provided to the supporting body 1 and the plural UV sterilizing lamps 9 housed in the light transmissive cylinders 8 are disposed to the of the stirrer 3. The ozone formed by the lamps 9 is injected and stirred into the water by the stirrer 3. The lamps 9 are so constituted that the distances from the stirrer 3 can be adjusted as desired. As a result, various kinds of the bacterium in the water are removed and org. materials are decomposed and removed further, the water- blooms generated in the water in summer or hot seasons are algaecided.

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, environmental pollution causes water quality to deteriorate and hinder 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 and the water becomes cloudy, making it difficult to observe ornamental fish and farmed fish. Obstructs and spoils the landscape.

Therefore, conventionally, filtration devices are constructed using special filters made of activated carbon, gravel, and organic materials to purify water.

However, filtration devices can absorb and remove foreign substances such as dirt in the water, but they cannot remove bacteria such as Vibrio, which causes fish diseases. Further, there are disadvantages in that removal of nitrite nitrogen, iron, and organic matter is insufficient, and algal blooms are not sterilized sufficiently.

Therefore, as other means, chemicals such as copper sulfate and sodium hypochlorite have been added to the water to remove E. coli, iron, and organic matter, and to sterilize algal blooms. However, it has the disadvantage that chemicals remain in the water and cause secondary pollution.

[Purpose of the invention]

The present invention was invented in view of the above-mentioned points, and an object of the present invention is to provide a water purification device that can remove various types of bacteria in water such as swamps, ponds, and fish farms, and can kill algal blooms. shall be.

[Means for solving problems]

The invention will now be explained with reference to the figures. In the figure, reference numeral 1 denotes a plate-shaped support provided in a swamp, pond, etc., and includes a plurality of holes 2. Reference numeral 3 denotes a stirring device provided near the center of the support 1, and 4 denotes a hollow ventilation pipe constituting the stirring device 3, which is made of stainless steel, for example. A rotating blade 5 is rotatably provided at the lower end of the ventilation pipe 4, and is connected to a motor 7 by a support rod 6. 8 is stirring device 3
9 is an ultraviolet germicidal lamp supported inside the translucent cylinder 8;
10 is a support plate for supporting the ultraviolet germicidal lamp 9 on the translucent cylinder 8; 11 is a hollow vibrator supported on the support plate 10 of the translucent cylinder 8; the lower end is connected to the translucent cylinder; 8, and its upper end protrudes above the support plate 10.

12 is a communication pipe connected to an upper part of the ventilation pipe 4; 13;
is a connecting pipe that connects the vibrator 11 and the communication pipe 12, and the ozone generated from the ultraviolet germicidal lamp 9 is passed through the ventilation pipe 4.
The rotary blade 5 is rotated through the water and injected into the water.

Further, the translucent cylinder 8 and the ultraviolet sterilizing lamp 9 mounted inside the translucent cylinder 8 are supported in desired holes 2 of the support 1, and configured so that the distance to the stirring device can be adjusted. It is.

Reference numeral 14 denotes support legs supported on the outer periphery of the four corners of the support body 1.

Additionally, in swamps, ponds, etc. where water volume control is inadequate, floats are installed in place of support legs to maintain a constant height of the ultraviolet germicidal lamp and the rotary blades of the stirring device.

[Action of the invention]

The water purification device described above is installed in a swamp, pond, etc., and the agitation device on the bottom of the support 1 and the ultraviolet germicidal lamp 9 attached to the transparent cylinder 8 on the bottom of the support 1 are immersed in the water. ,
When the rotary blades 5 of the stirring device 3 are rotated and the ultraviolet sterilizing lamp 9 is turned on, the ultraviolet rays of 253.7 ms generated by the ultraviolet sterilizing lamp 9 sterilize various fish disease bacteria in the water and also remove organic substances harmful to fish in the water. It photooxidizes and decomposes, and also kills floating algae in the water.

Further, ozone generated from the ultraviolet germicidal lamp 9 is introduced into the ventilation pipe 4 from the translucent cylinder 8 through the connecting pipe 13,
Ozone is injected and stirred into the water by the rotary blade 5, and the strong oxidizing power of ozone sterilizes various pathogenic bacteria such as Aeromonas bacteria, Vibrio bacteria, Acria bacteria, and Kodwajira bacteria in the water, and further oxidizes nitrite nitrogen, iron, and organic matter. Disassemble and process.

Furthermore, by changing the distance from the stirring device 3 to the ultraviolet sterilizing lamp 9 attached to the translucent cylinder 8, the area of water to be treated by the ultraviolet rays 253.7 as generated by the ultraviolet sterilizing lamp 9 can be changed.

〔Effect of the invention〕

As described above, the present invention provides a support with an agitation device having rotary blades for agitating water, an ultraviolet germicidal lamp housed in a translucent cylinder on the outer periphery of the agitation device, and Since the germicidal lamp was constructed so that its distance from the stirring device could be adjusted, as mentioned above, the ultraviolet 25
3.7 m and ozone sterilizes E. coli, etc. in the water, decomposes and removes organic matter, and also eliminates blue-green algae that occurs in the water in the summer.

It can kill algae, promote the growth of fish, and prevent water from becoming cloudy, improving the appearance of ornamental fish.

Furthermore, unlike conventional devices that use chemicals, secondary pollution due to chemicals does not occur.

Also, by changing the position of the UV germicidal lamp, the area of water to be treated can be changed, which is very useful.
