Description
前記膜分離槽が、前記膜ユニット全体を収容する下部容器と、この下部容器の上部開口部上に設けられた上部容器とからなり、
前記上部容器の水平断面積が、前記下部容器の前記上部開口部の水平断面積より小さくなるように構成されていることを特徴とする。
メタン発酵槽10においてメタン発酵処理された後の発酵廃液は、間欠暴気槽20に送られる。この間欠曝気槽20では、曝気装置21からで空気を供給して酸素濃度を高めて硝化反応を行う曝気工程と、空気の供給を停止して脱窒反応を行う攪拌工程を交互に繰り返す回分処理により、全窒素(T−N)の低減を行なう。その後、間欠暴曝気槽20の上澄水は、膜分離槽30にオーバーフロー水として流入口36より流入し、例えば孔径0.2μm程度の複数の膜エレメント33を通過して膜ろ過処理されて固液分離される。そして、膜エレメント33毎にチューブ37によってヘッダー管38に集水された後、流出口39から次工程の処理水槽41へと排出される。
