Description
この浮上分離装置10Bでは、撹拌槽11の上側を横断するクロスビーム60の両端は、スクリュージャッキ等の昇降装置61に支持されており、クロスビーム60は昇降装置61によって上下動可能とされている。この実施の形態では、堰板13は固定板により構成されており、可動式ではないが、図1,2の実施の形態と同じく可動式とされてもよい。
この浮上分離装置10Bのその他の構成は浮上分離装置10と同様であり、同一符号は同一部分を示している。
この浮上分離装置10Bにおいても、浮上分離装置10と同様にして原水が処理される。この浮上分離装置10Bにあっては、昇降装置61によって撹拌ポンプ12の設置高さを調整することにより、撹拌ポンプ12の吸込口と撹拌槽11内の水面との距離を調整し、ポンプ12による空気巻込量を調整することができる。
図示は省略するが、図3,4の浮上分離装置10Aにおいても、図5,6のように昇降装置61によって撹拌ポンプ12を設置高さ調整可能としてもよい。
本出願は、2016年10月5日付で出願された日本特許出願2016-197299に基づいており、その全体が引用により援用される。
