Description
図6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。
本発明の目的は、上記従来技術の問題点を解消し、被処理水の停滞領域を少なくし、処理槽全体を好気状態に維持することができ、処理効率のよい膜分離式活性汚泥処理装置を提供することにある。
Claims (1)
- 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、その側面を前記処理槽の側壁と間隔を空けて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た膜分離式活性汚泥処理装置において、前記膜ユニットを複数枚の鉛直状の平膜が間隔を空けて平行に配列された構造とするとともに、前記微細気泡散気手段を前記膜ユニットの側面と処理槽の側壁に挟まれた領域で、かつ前記平膜と平行な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。
