Claims

[Scope of Claim for Utility Model Registration] (1) A device for purifying water in an aquarium containing fish and shellfish while circulating it, the device comprising a pre-processing device and a biological treatment device, the pre-processing device comprising: A first cylindrical body forming an annular chamber between the tank-shaped body and the inner surface of the tank that extends from the top of the tank-shaped body to the tank bottom, one end of which opens into the annular chamber and the other end of which is a pump. The sewage introduction system, which communicates with the water tank through the tank and is equipped with a gas mixing mechanism in the middle, is positioned so as to form an annular flow path that communicates with the annular chamber with the first cylindrical body, and the upper end is connected to the inside of the tank. A second cylindrical body is opened at a height that does not reach the top, while its lower end communicates with the biological treatment machine via a treated water take-off system, and a conduit communicates with the top closed space of the annular chamber to collect gas. A filth removal mechanism is provided for discharging filth containing pollutants entangled with and collected by fine air bubbles created by stirring the mixed sewage out of the tank, and downstream of the filth removal mechanism, foam particles are removed from the foamy filth. The secondary treatment mechanism is equipped with a foam separation section that collects the foam and a filtration section for the water that passes through this, and further separates the foam from the waste discharged from the waste removal mechanism, filters the water, and directly releases the water. A water purification device for live fish tanks, characterized in that the water is returned to the tank indirectly. (2) The separating section has a cylindrical body with a perforated plate inside, a fine mesh filter member is arranged in the upper chamber above the perforated plate, and the end of the conduit from the waste removal mechanism is connected to the upper chamber. It opens toward the front wall, and a conduit for taking out the secondary treated foam material is connected to the same space, and the filtration part communicates with the lower chamber of the perforated plate, and the inside is filled with the necessary filter material. A water purification device for live fish tanks as set forth in claim 1. (3) The separating section is made of a cylindrical body, a perforated plate is stretched inside the cylindrical body, a fine mesh filter member is arranged on the perforated plate, and the end of the conduit from the waste removal mechanism is connected to the perforated plate. The water of the live fish tank according to claim 1 of the utility model registration claim, which opens toward the upper front wall, the filtration part communicates with the chamber below the partition plate, and the inside is filled with the required filter material. Purification device. (4) The separation part is made of a cylindrical body, the inside of the cylindrical body is divided into at least two chambers by a partition plate, a fine mesh filter member is arranged in each chamber, and the lower part of the partition plate is communicated with by a water hole. The end of the conduit from the waste removal mechanism opens toward the first partition plate, and the filtration part communicates with the lower part of the final chamber, and the inside is filled with the required filter material. The water purification device for live fish tanks according to item 1.
