Abstract
【解決手段】直列に連結された第1曝気槽10と第2曝気槽20とを用い、これら二つの曝気槽で、間欠曝気処理を行うことにより、排水中の窒素及びリンを除去する。次いで、間欠曝気処理後の第2曝気槽内の排水を、膜分離装置30に導入して処理水と濃縮汚泥に分離し、該濃縮汚泥を第1曝気槽10及び第2曝気槽20に返送すると共に、第1曝気槽10への返送量を、第2曝気槽20への返送量よりも少なくする。

Claims (4)
- 第1曝気槽とこの第1曝気槽に直列に連結した第2曝気槽とを用い、これら二つの曝気槽で、排水の曝気を行う状態と、曝気を停止して攪拌を行う状態とを繰り返す間欠曝気処理を行うことにより排水中の窒素及びリンを除去する排水処理方法であって、
間欠曝気処理後の前記第2曝気槽内の排水を、膜分離装置に導入して処理水と濃縮汚泥に分離し、該濃縮汚泥を前記第1曝気槽及び第2曝気槽に返送すると共に、前記第1曝気槽への返送量を、前記第2曝気槽への返送量より少なくすることを特徴とする排水処理方法。 - 前記濃縮汚泥を、滞留槽に導入して該濃縮汚泥中の溶存酸素を減少させた後、前記第1曝気槽及び第2曝気槽に返送する、請求項1に記載の排水処理方法。
- 前記第1曝気槽が曝気を停止した状態であって、かつ、前記第1曝気槽内に溶存酸素、亜硝酸性窒素及び硝酸性窒素が存在しない場合、前記濃縮汚泥を前記第2曝気槽のみに返送する、請求項1又は2に記載の排水処理方法。
- 前記第1曝気槽にORP計を設置し、前記第1曝気槽内のORP値が、脱窒終了の屈曲点を示すまでは、前記濃縮汚泥を前記第1曝気槽及び第2曝気槽に返送し、前記第1曝気槽内のORP値が、屈曲点を示した後で増加へ転ずるまでは、前記濃縮汚泥を前記第2曝気槽のみに返送する、請求項1〜3のいずれか一つに記載の排水処理方法。
