- 担体含有水を処理槽上部に上昇させる上昇流路及び上昇流発生手段と、上昇した担体含有水を処理槽下方に向けて流下させる下降流路とを設けた処理槽内に生物膜付着担体を投入した流動床によって下排水の処理を行う排水処理装置において、前記上昇流発生手段は、処理槽内から抜出管を介して処理槽外に抜出した担体含有水を上昇流路となる吐出管を介して処理槽上部に汲上げるポンプであり、前記下降流路は、処理槽内に設けられた内外二重構造に形成された筒体の内筒と外筒との間に形成され、前記外筒は、前記吐出管から外筒の上部内に流入した担体含有水が、内筒と外筒との間に旋回流を形成するよう、前記吐出管を外筒に対して接線方向に接続するとともに旋回流中の比較的比重の大きな担体を外筒の壁面に沿って流下せしめて前記処理層内に戻すための開口を下端に設け、前記内筒は、内筒と外筒との間で前記担体から剥離した生物膜が内筒の外周部を上昇する水と共に上昇して内筒内に流入して排出されるよう、上端を外筒内の水面部分に開口させて下部を洗浄排水の排出部に接続したことを特徴とする流動床式排水処理装置。
- 前記吐出管内にスタティックミキサーが設けられていることを特徴とする請求項1記載の流動床式排水処理装置。
