MESH TYPE BIO- FILTERING TANK FOR THE CAPABLE OF SOLID REMOVAL AND IT'S REUSE

摘要

The present invention relates to a filtering tank for filtering the rearing water discharged from a rearing aquarium. More specifically, the present invention relates to a mesh-type bio-filtering tank. An inflow water path and an outflow water path for the rearing water are formed at the top end of a body casing. The internal space of the body casing is divided into an inflow space and an outflow space by a central separation plate. In each space, multiple pieces of mesh filtering plates equipped with fiber sieves are installed at regular intervals and horizontally with respect to a water flow direction. A funnel plate and a discharge pipe are installed inside the body casing which corresponds to the bottom of the mesh filtering plate so as to precipitate and discharge solids. The solids included in the rearing water are precipitated on the bottom of the filtering tank in order to be collected. Fine solids and organic components included in the rearing water are bonded to the sieves of the mesh filtering plates in order to be used for culturing useful microorganisms. Accordingly, the solid filtration and the microorganism filtration are performed at the same time in one filtering tank. The mesh filtering plates themselves can be inserted in other water tanks for culturing marine organisms so that the organic materials and cultured microorganisms bonded to the sieves can be used as a food for the marine organisms and the mesh filtering plates are thereby cleaned to be re-mounted. Even when the organic materials bonded to the sieves are used as a fertilizer, the desalinization can be performed easily by dipping the mesh filtering plates in fresh water. In the present invention, the filtration efficiency of the filtering tank is improved, and the components collected from the filtering tank can be effectively recycled.
