ペレットの有効表面積は必ずしも大きくはない。In the above-mentioned known apparatus and processing tank, a large amount of pellets are piled up in a water tank, so that a large amount of pellets are uniformly consumed and uniformly worn. Even if the upstream drainage of the circulating wastewater wears down, the downstream drainage hardly wears down, and a small amount of pellets are collected to accurately determine the timing of pellet replacement and replenishment. It is difficult. Therefore, in general, the pellet storage container is taken out of the water storage tank using a heavy machine such as a crane, and the state of wear of the pellet is checked. However, the check requires a lot of time and cost. In addition, a large amount of pellets are in contact with each other in the storage container, and the effective surface area of the pellets that can come into contact with drainage is not always large.
