Description
図1に示した排水処理装置を用い、嫌気槽1の容量を12L、好気槽2の容量を12L、沈殿槽3の容量を6Lとし、BOD:240mg/l、SS:160mg/l、P:7mg/l、N:18mg/lという生活排水を24L/dで流した。嫌気槽1では、3回/1日、1時間の撹拌、すなわち、7時間停止、1時間撹拌の8時間のセットを1日に3回繰り返し行った。
嫌気槽1での撹拌を連続撹拌とした点以外は、実施例1と同様とした。
図1に示す装置の嫌気槽1も曝気して好気槽とし、この好気槽と後段の好気槽2での汚泥濃度を3000mgMLSS/lに維持し、全体を標準活性汚泥法による運転とした。
Claims (2)
- 有機性排水を嫌気槽に導入して嫌気性処理し、前記嫌気槽から活性汚泥を含む処理水を好気槽に導入して好気性処理し、前記好気槽から活性汚泥を含む処理水を固液分離手段に導入して固液分離し、前記固液分離手段で分離した活性汚泥を返送汚泥として汚泥返送ラインを介して前記嫌気槽又は当該嫌気槽より上流に返送する排水処理方法であって、
前記嫌気槽内を、一定周期で間欠に撹拌し、
前記嫌気槽の汚泥濃度を10000〜17000mgMLSS/lとすると共に酸化還元電位を−400〜−450mvとして、嫌気性処理することを特徴とする排水処理方法。 - 前記嫌気槽内を、2回/1日又は3回/1日、1時間撹拌することを特徴とする請求項1記載の排水処理方法。
