  First, the circulation pump 50 is started to inject seawater in the pump tank 5 into the sterilization tank 6. The seawater in the pump tank 5 is cooled or heated to a set water temperature (for example, approximately 18 ° C.) by a cooler 51 or a heater and maintained.

  Bacteria, bacteria and other microorganisms floating in running water inside the sterilization tank 6 are efficiently killed and processed. Seawater that has been treated and maintained at the set water temperature flows into the water pipe 20 from the upper part of the sterilization tank 6. Since this water pipe 20 is immersed in the seawater in the water tank 2 having heat insulation properties, it is not affected by the outside air temperature and there is no risk of heat loss.

  Seawater that has passed through the water pipe 20 is discharged into the water tank 2 from the discharge port 21. Seawater in the aquarium 2 flows into the foam separation tank 3 through a sewage outflow slit 32 at the bottom of the aquarium 2. At this time, the foreign matter sinking to the bottom of the water tank 2 also flows into the foam separation tank 3 together with the seawater.

  In the foam separation tank 3, the pollutant discharge pipe 36 causes the polluted air bubbles 35 generated by the foam separation / dispersing device 34 and accumulated in the upper part of the foam separation tank 3 to flow out. In addition, the water collecting device 37 preferentially sucks the bubbles 35 a on the water surface of the water tank 2 and the water into the foam separation tank 3.

  Large foreign matter mixed in the seawater in the foam separation tank 3 floats upward by bubbles generated from the foam separation / dispersion device 34 and is removed by the filter 45. The seawater from which the foreign matter has been removed is filtered from the upper part of the next filtration tank 4 to the filter medium 43 and the porous plate 42 inside, and flows into the pump tank 5. The seawater controlled to the set water temperature circulates again through the filtration process and the sterilization process.

  As described above, the live fish tank apparatus 1 according to the present embodiment has almost no heat loss of the circulating seawater, and can stably and accurately control the temperature of the seawater. And since the water pipe 20 is only attached to the inner surface of the water tank 2, the attaching operation | work can also be performed easily.
