| 摘要 |
The present invention relates to a plankton culturing device comprising: a raw water separation tank for feeding raw water and separating the raw water into plant plankton and animal plankton; a plant plankton culturing tank disposed in a lower side of the raw water separation tank, and feeding and culturing the plant plankton; an animal plankton culturing tank disposed in a lower side of the plant plankton culturing tank, feeding the animal plankton from the raw water separation tank, provided with the plant plankton cultured in the plant plankton culturing tank, and having a sludge discharging hole penetrating through the bottom surface thereof; a sludge collecting pipe coupled with a lower side of the animal plankton culturing tank to be connected with the sludge discharging hole, and collecting sludge; and a sludge discharging cap coupled with the sludge discharging hole, discharging sludge to the sludge collecting pipe, and blocking sludge from being backwardly fed to a culturing tank main body from the sludge collecting pipe. The present invention is capable of maintaining the inside of the device clean by discharging sludge inside the animal plankton culturing tank to the outside. |
