Abstract

PROBLEM TO BE SOLVED: To purify water so as to be safe to human bodies without deteriorating a water tank and the like by generating metallic ions in water by a metallic ion generating means and sterilizing by an ultraviolet sterilization means. SOLUTION: A sterilization purifying device 1 comprises a filter device 2 with a filter 3 in a filter tank 4, a silver ion generating device 5 as a metallic ion generating means and an ultraviolet sterilization device 6. Silver ions are generated by applying power from a direct current power source 9 to between a silver anode 7 and a silver cathode 8 in the silver ion generating device 5. A waterproof type ultraviolet sterilization lamp 12 having the main wave length of approximately 0.254μm is disposed in the ultraviolet sterilization device 6. Water in a water tank 13 is fed from an inflow opening 14 to the ultraviolet sterilization device 6 through the silver ion generating device 5 and circulated from an outflow opening 15 to the water tank 13. During the above process, silver ions are added and sterilized by the emission of ultraviolet rays. Legionella and colon baccilli are killed by the arrangement to keep the water clean at all times.

However, in such a conventional water purifying device for appreciation fish and bath, there are many problems because ozone is used to sterilize the water.
First, in the conventional aquarium fish tank, (1) the transparent acrylic resin water tank is gradually oxidized by ozone and may be deteriorated, which is dangerous. (2) Since the microorganisms that purify the water in the aquarium are sterilized by breeding on the sand or the like at the bottom of the aquarium, the water in the aquarium becomes dirty immediately. (3) If the remaining ozone is released into the room, there is a risk of harming the human body. (4) Breeding of ornamental fish and aquatic plants is poor. There are drawbacks such as.

Further, in the conventional bath water purifying apparatus, (1) it is conceivable that a plastic bathtub or bath lid is gradually oxidized by ozone and deteriorates. (2) If the remaining ozone goes out into a small bathroom, there is a risk of harming the human body. (3) Since stearic acid and nitrogen compounds, which are the main components of stains in bath water, cannot be decomposed, it is difficult to clean the bath water. (4) The wall surface of the bathtub becomes dirty. (5) Since water clusters are large, it is difficult for water to be absorbed by the human body. There are drawbacks such as. Due to such drawbacks, it was very inconvenient for water purification.

The water in the water tank 13 passes from the inflow port 14 through the outward path 16a, enters the filtration tank 4 of the filtration device 2 and removes dirt with the filter 3, and then enters the silver ion generation device 5 from the inlet 10. Silver ions are added. At this time, in the silver ion generator 5, cation impurities such as calcium and magnesium contained in water are deposited and adhered to the cathode 8 side during electrochemical generation of silver ions to form a scale. The amount of this scale increases as the energization time increases, and when it reaches a certain amount, the ability to generate silver ions is extremely reduced and the electrode itself also corrodes. In order to remove such a scale, a voltage with polarity reversed is applied to the anode 7 of the cathode 8 to which the scale is attached by the inversion signal from the control circuit 31 at regular intervals, and the scale is eluted in water and washed. Therefore, the polarity was periodically reversed to remove the scale automatically, enabling continuous generation of silver ions.

[0024] In addition, there was no breeding of Legionella bacteria, general bacteria and algae, and the aquarium and water were clean during the experimental period of 3 months. The water became dirty and algae were generated, so I changed the water and cleaned it every two weeks. Furthermore, the growth of the ornamental fish 21 and the aquatic plant 20 was also better in this example. This is because, as shown in Table 1, Table 2 and FIG. 1, the present Example can prevent the propagation of Legionella bacteria, general bacteria and algae without using ozone which is considered to be harmful to the living body unlike the conventional example. , And because it does not use ozone, microorganisms that decompose nitrogen compounds in water are sand 1
It is easy to breed on the surface of 9 and also ornamental fish 21 and aquatic plants 20
It can be inferred that the water is gentle.

[Function] The bath water in the bathtub 50 flows from the inflow port 51 to the outward route 53a.
After passing through a filter tank 33 of the filter device 33 to remove dirt such as hair and lint by the filter 34, the silver ion generator 36 is introduced from the inlet 42, and silver ions are added there. At this time as well, in the silver ion generator 36,
When electrochemically generating silver ions, cation impurities such as calcium and magnesium contained in water are precipitated and attached to the cathode 40 side to form scales. The amount of this scale increases as the energization time becomes longer, and when it reaches a certain amount, the ability to generate silver ions extremely decreases. The cathode 40 to which the scale is attached is applied to the anode 39 from the control circuit 31 of FIG. 2 by applying a voltage whose polarity is inverted by an inversion signal at regular time intervals to elute the scale in water to continuously generate silver ions. Made possible.

The results are shown in Table 4, FIG. 5, FIG. 6, FIG. 7 and FIG.

It can be seen from FIG. 4 that in this embodiment, four adults can sterilize Legionella bacteria that propagate after bathing. It can be presumed that this was sterilized by the silver ions added to the bath water as described above. Also, from FIGS. 5 and 6, in the present embodiment, even when four adults repeatedly bathed the same bath water every day, the turbidity and C of the bath water
It can be seen that the OD is very small. This is presumed to be always clean water because organic matter in the bath water is decomposed by active oxygen. Further, since the organic matter was decomposed, the wall surface and the bottom portion of the bath 50 were also very clean. In addition, it was confirmed from FIGS. 7 and 8 that sodium stearate, which is the main component of stains in bath water stains, and ammonia, which is a malodorous component, can be decomposed by active oxygen, so that organic substances and malodorous components in bath water are decomposed. It became clear.

Further, bath water in which active oxygen was dissolved to 500 PPm and bath water aerated with a conventional jet device were used to measure a nuclear spectrum and calculate a half width by using NMR (nuclear magnetic resonance spectroscopy). I went. The results are shown in FIGS. 9 and 10. From FIGS. 9 and 10, it was confirmed that when active oxygen was generated in water, the full width at half maximum of the nuclear spectrum measured by NMR was narrowed and the water clusters were changed small. This phenomenon is caused by two active hydrogen atoms (H) and two oxygen atoms (O) having high activity generated in water.
Water molecule group consisting of weak hydrogen bond at the stage of directly acting on water molecule consisting of one electron bond, breaking the bond electron pair of water molecule itself due to its high electronegativity, and forming another bond electron pair ( It is presumed that it has a strong influence on H 2 O) n. The water with small clusters is a kind of water that is easy to use for living organisms because the penetration of cells into living tissues is smooth. In this example, manganese dioxide was used for the catalyst 44 of the active oxygen generator 37, but the same result was obtained by using manganese, molybdenum, an oxide of molybdenum, or the like.
