Provided is a multi-level apartment type three-dimensional water tank, partitioned in front, rear, left and right directions in a multi-level structure and provided with a water tank sill support having an open top surface to accommodate the lower part of modular glass water tanks. The present multi-level apartment type three-dimensional water tank solves a problem such that the modular glass water tank made from glass or synthetic resin such as acryl can break due to slipping, which is caused by weak frictional force between the modular glass water tank and a bottom surface on which the modular glass water tank is provided, and facilitates the installation and separation of the three dimensional water tank and each modular glass water tank. The present water tank also makes it possible to recycle into nutritional contents needed for the growth of plants, organic and inorganic substances present as sources of pollution in culture water which are generated when fish is cultured, so as to decompose eutrophic substances interrupting the cultivation of fish in a plant cultivation step, thereby absorbing the decomposed substances as nutrients. Overall, the present multi-level apartment type three-dimensional water tank filtrates and purifies culture water in ecofriendly manner and helps establish an yearly sustainable organic agricultural product and fishery product production and supply system without locational and geographical limitations. |
