Claims (7)
- 魚介類を飼育する飼育水槽に水を循環させる循環経路に、水中のアンモニアを処理する生物ろ過槽を接続して設け、生物ろ過槽を、ろ材を流動状態で内蔵した上流側の流動槽と、ろ材を静置させた状態で内蔵した下流側の固定槽とを備えて形成し、固定槽内のろ材を洗浄する機能を有する循環ろ過式養殖装置において、上記生物ろ過槽を複数備え、この複数の生物ろ過槽を循環経路に並列に接続し、各生物ろ過槽の流動槽と固定槽にそれぞれエアを吐出するエアレーション部を設け、各エアレーション部にエアを供給する経路に、各生物ろ過槽のうち、任意の一つの生物ろ過槽の固定槽のエアレーション部にのみエアを供給すると共に他のエアレーション部にはエアの供給を停止する切り替え手段を設けて成ることを特徴とする循環ろ過式養殖装置。
- 循環経路から任意の各生物ろ過槽への流路を開閉する流路開閉手段を備えると共に、各生物ろ過槽の固定槽に開閉可能な排水部を備えて成ることを特徴とする請求項1に記載の循環ろ過式養殖装置。
- 各生物ろ過槽の流動槽と固定槽のうち、少なくとも流動槽の内側面を底部から水深の10〜30%までの範囲で内側へ向けて下り傾斜する傾斜面に形成して成ることを特徴とする請求項1又は2に記載の循環ろ過式養殖装置。
- 各生物ろ過槽の流動槽内へのろ材の充填量を、ろ材が沈降して堆積した状態での容積が、ろ材が流動する室内の水の容積の20〜80%の範囲になるように設定して成ることを特徴とする請求項1乃至3のいずれかに記載の循環ろ過式養殖装置。
- 水中の有機物の除去を行なう泡沫分離槽を、生物ろ過槽の上流側に接続して備えて成ることを特徴とする請求項1乃至4のいずれかに記載の循環ろ過式養殖装置。
- 複数の各生物ろ過槽と泡沫分離槽とを一体化して浄化槽を形成して成ることを特徴とする請求項5に記載の循環ろ過式養殖装置。
- 生物ろ過槽もしくはその上流側の位置に、水温調整用の熱交換器を設けて成ることを特徴とする請求項1乃至6のいずれかに記載の循環ろ過式養殖装置。
