【Example】

 Hereinafter, the present invention will be specifically described with reference to the embodiments shown in the drawings. FIG. 1 is a vertical cross-sectional view showing an embodiment of the water treatment apparatus for aquarium according to the present invention, FIG. 2 is an enlarged vertical cross-sectional view of the main part thereof, and FIG. 3 is a cross-sectional view of an ozone generator.

In the figure, reference numeral 1 denotes a box-shaped water tank made of transparent synthetic resin, glass or the like having an open upper surface. Fresh water or sea water is stored in the water tank 1 to breed live fish or the like. A circulation type filter 2 is disposed above the water tank 1 to sequentially circulate and filter the water in the water tank. The filter 2 has a configuration in which a filter medium storage chamber 5 defined by a partition wall 4 is formed in a container 3 placed on the upper part of the water tank 1, and a filter medium 6 is accommodated in the storage chamber 5. .

The filter 2 is provided with a pump 7 that pumps up the water in the water tank 1 and guides it into the filter 2. The pump 7 guides the water in the water tank 1 into the lower pipe 7e through the strainer 7d by rotating the rotary blades 7b in the pump chamber 7a with the motor 7c, and passes through the pump chamber 7a to the upper pipe. It is configured to be ejected from the 7f to the upper portion of the filter medium 6. The water jetted to the upper portion of the filter medium 6 is filtered by the filter medium 6 and flows down from a large number of small holes 4a formed in a fixed portion of the partition wall 4 to the bottom of the container 3 and temporarily collects at the bottom. After that, it is returned to the water tank 1 through the discharge port 8 again.

In the present invention, an ozone generator 10 using an ultraviolet lamp is arranged in the vicinity of the circulation type filter 2 as described above. In this embodiment, the flow rate is set in the container 3 of the filter 2. An ozone generator 10 is arranged near the outlet 8. The ozone generator 10 is configured such that an ultraviolet lamp 12 is held substantially concentrically by a space holding spacer 13 in an ultraviolet ray transmissive cylindrical body 11 made of quartz glass, fluororesin, or silicon resin. The bases 14 and 15 having the air inlet / outlet ports 14a and 15a are fitted and fixed to both ends. In the ozone generator 10, the inflow / exhaust ports 14a, 15a provided in the bases 14, 15 are inserted through holes 16a formed in a box-shaped support member 16 which also serves as a reflection plate to be mounted and supported. The member 16 is attached to the inner surface of the lid 3a of the container 3 above the outlet 8 with an adhesive or the like.

The above-mentioned ultraviolet lamp 12 is connected to a power source through a lead wire 17 and an inverter (not shown), and is configured to emit ultraviolet rays having a wavelength of 253.7 nm as a main component. In addition, hoses 18 and 19 are connected to the inflow / exhaust ports 14a and 15a, respectively, one hose 18 of which is an air source such as an air pump not shown in the figure, and the other hose 19 of which is shown in FIG. As shown, they are connected to the bubble generators 20 in the water tank 1, respectively.

In the above-mentioned configuration, air from an air generation source (not shown) is introduced into the cylindrical body 11 via the hose 18 and is irradiated with ultraviolet rays from the ultraviolet lamp 12 to gradually generate a small amount of ozone. Is generated. Next, the air in the cylinder 11 containing the ozone is guided to the bubble generator 20 in the water tank 1 through the hose 19 and becomes fine bubbles to be discharged into the water in the water tank 1. Part of the air containing ozone released into the water can be dissolved in the water to replenish the dissolved oxygen in the water.

Moreover, by replenishing the amount of dissolved oxygen as described above, turbidity and odor of the water tank are removed, and at the same time, organic substances are oxidatively decomposed due to the synergistic effect of water convection, and particularly ammonia from excretions is removed. It can be decomposed to improve water quality. In addition, the water in the water tank can be sterilized by the ozone described above. Further, the ultraviolet rays emitted from the ultraviolet lamp 12 at the same time as the generation of ozone is transmitted through the tube body 11 having ultraviolet transparency and collected in the vicinity of the discharge port 8 at the bottom of the container 3 to collect the filtered water W. It is irradiated with water and sterilized to obtain an efficient water treatment device.

When the ozone generator 10 is arranged in the vicinity of the outflow port 8 of the filter 2 as in the above-described embodiment, particularly when the ozone generator 10 is arranged directly above the outflow port 8 as shown in FIG. If there is a risk that ultraviolet rays from 8 will enter the water tank 1 and adversely affect raw fish, etc., a light-shielding member may be provided in the opening of the outlet 8 or in the vicinity thereof, if necessary, or the ozone generation described above may occur. You may make it arrange | position the container 10 avoiding the position just above the outflow port 8.

The ozone generator 10 is not limited to the vicinity of the outflow port 8 and may be arranged, for example, above the filter medium 6 in the filter 2 or at another position. In that case, the ozone generator 10 is attached to the inner surface of the lid 3a or the inner surface of the side wall of the container 3 as in the above-described embodiment, or an opening is formed in the lid 3a or the side wall of the container 3 and the ozone generator is provided outside thereof. 10 is arranged, or a concave portion is formed on the inner surface of the lid 3a or the inner surface of the side wall of the container 3, and the ozone generator 10 is housed and arranged in the concave portion.

Further, the ozone generator 10 can be housed and arranged in the cylindrical discharge port 8, and FIG. 4 shows an example thereof. That is, in the embodiment shown in the figure, as in the case of the above-mentioned embodiment, an ozone generator 10 having an ultraviolet lamp 12 housed in a cylindrical body 11 having ultraviolet transparency is concentrically arranged in a cylindrical discharge port 8. It is housed and arranged in a shape. In the figure, 21 is a support projection of the ozone generator 10 provided on the inner surface of the discharge port 8, and 22 is a spacer for maintaining the distance. The other structure is the same as that of the above-mentioned embodiment, and the members having the same functions as those of the above-mentioned embodiment are designated by the same reference numerals, and the repeated explanation is omitted.

Since the ozone generator 10 is housed and arranged in the discharge port 8 as described above, the ultraviolet rays from the ultraviolet lamp 12 of the ozone generator 10 are transmitted through the cylindrical body 11 having ultraviolet transparency. The filtered water W flowing into the discharge port 8 is successively irradiated to sterilize the filtered water. The ozone generated by the ozone generator 10 is guided to the bubble generator 20 via the hose 19 as in the above-described embodiment, and becomes bubbles to partially dissolve in water to increase the amount of dissolved oxygen in water. This is the same as the case of the above embodiment.
