Abstract
【解決手段】 槽内に保持した活性汚泥によって被処理水を好気的に処理する処理槽10と、この処理槽10内に浸漬された膜ユニット14と、この膜ユニット14の下方に配置された粗大気泡散気手段16と、処理槽10内に配置された微細気泡散気手段18とを備え、粗大気泡散気手段16から散気した粗大気泡のエアリフト作用によって処理槽10内に上下方向の旋回流を形成するようにした膜分離式活性汚泥処理装置において、微細気泡散気手段18を旋回流の下向流の領域に配置したことを特徴とする。
【選択図】 図1
Description
図5はその概略構成を示す装置系統図である。処理槽1内には活性汚泥が高濃度に保持されており、被処理水2を好気的に処理する。処理槽1内には膜ユニット3が浸漬されている。膜ユニット3の下方には粗大気泡散気手段4が配置されている。また、粗大気泡散気手段4のさらに下方には微細気泡散気手段5が配置されている。
Claims (2)
- 槽内に保持した活性汚泥によって被処理水を好気的に処理する処理槽と、この処理槽内に浸漬された膜ユニットと、この膜ユニットの下方に配置された粗大気泡散気手段と、前記処理槽内に配置された微細気泡散気手段とを備え、前記粗大気泡散気手段から散気した粗大気泡のエアリフト作用によって前記処理槽内に上下方向の旋回流を形成するようにした膜分離式活性汚泥処理装置において、前記微細気泡散気手段を前記旋回流の下向流の領域に配置したことを特徴とする膜分離式活性汚泥処理装置。
- 前記微細気泡散気手段が処理槽の水深の1/2よりも深く、前記粗大気泡散気手段よりも浅い位置に設置されたことを特徴とする請求項1に記載の膜分離式活性汚泥処理装置。
