Abstract
【解決手段】 片面にアナモックス菌6を付着させて円柱状に巻き回したロール状担持体4を、上下に通孔5aを有する押え板5で挟持して、脱窒槽2に内設し、上向流により原水を脱窒槽2に供給して、アナモックス反応により脱窒処理を行う。アナモックス菌6の槽外への流出は極めて少なく、槽内の高濃度化を維持管理できる。菌の担体への担持作業や、担持体の取扱が容易で、作業効率がよい。

Claims (4)
- 脱窒槽の内部に独立栄養性脱窒菌を充填し、脱窒槽(2)に供給する原水中のアンモニア性窒素を窒素ガスとして連続的に除去する脱窒装置の生物担体において、培養したアナモックス菌(6)を担持シート(9)でろ過した後、ろ過面を内側にして円柱状に巻き回し、所定の幅で切断してロール状担持体(4)を構成することを特徴とする微生物担持体。
- 脱窒槽の内部に独立栄養性脱窒菌を充填し、脱窒槽(2)に供給する原水中のアンモニア性窒素を窒素ガスとして連続的に除去する生物脱窒装置(1)において、片面にアナモックス菌(6)を付着させて円柱状に巻き回した所定の幅のロール状担持体(4)を脱窒槽(2)に配設し、ロール状担持体(4)の外周面を脱窒槽(2)に内接させたことを特徴とする生物脱窒装置。
- 上記ロール状担持体(4)を上下に通孔(5a・・・)を有する押え板(5、5)で挟持して、脱窒槽(2)に内設したことを特徴とする請求項2に記載の生物脱窒装置。
- 上記押え板(5、5)で挟持したロール状担持体(4)を所定の間隔を空けて脱窒槽(2)に多段に配設したことを特徴とする請求項3に記載の生物脱窒装置。
