Description

  The present invention relates to an aquarium water purification apparatus for circulating and purifying stored water in an aquarium for breeding ornamental fish, edible fish, shellfish, and the like.

  When fish, shellfish, etc. are bred and watched in the aquarium, it is important to change the water for water quality management. The water stored in the aquarium contains ammonia components generated from fish excrement, etc., residual food, garbage, etc., which cause water quality deterioration. In particular, ammonia component and nitrite produced in the process of ammonia component being decomposed to nitrate by aerobic bacteria naturally contained in aquarium water are extremely harmful for domestic fish, etc. It has also become a cause of generating and breaking pH balance.

  For this reason, various types of devices that circulate aquarium water and purify them chemically, physically or microbiologically have been proposed. As a microbiological purification apparatus, for example, as shown in Patent Document 1, a purification apparatus in which an anaerobic purification module, a water pressure feeding means, an aerobic purification module, a water temperature control sterilization module, and the like are connected by piping, As shown in the figure, a filtration device is provided at the top of the water tank body, and the filtration device is composed of an anaerobic wet septic tank and an aerobic dry filtration tank, and both tanks are supplied with water from above by a shower pipe. A filtration device is known in which a part is returned to aquarium water through a dry filtration tank and the rest is passed through a wet filtration tank and then returned to the water tank via the dry filtration tank.

  However, since the apparatus of Patent Document 1 is composed of a large number of modules and each module is connected by piping, there is a problem that the structure is complicated and the entire filtration apparatus is enlarged. Moreover, the apparatus of the literature 2 has a problem that there is a restriction on an installation place because it is placed on the upper part of the water tank body, and a problem that it is difficult to manage and maintain each septic tank in a state suitable for each microorganism. Furthermore, these apparatuses have a problem that at the start of the purification process, it takes time until the microorganisms propagate in each filtration container, and an appropriate purification process is not performed during that time.
