Abstract
Description
本発明によって開発された順次間欠的なオゾン処理によれば、大量に生成される余剰汚泥を、とても短い接触時間において、大量に、最小限のオゾン処理によって、消化および安定化することができる。
第1セットの実験において、2分、3分、4分、6分間、試料をオゾン処理した後に得られた結果を図1に示す。これらの実験の終了後、2分および3分間のオゾン処理では不十分であることが観察された。これに加えて、図2より、6分間オゾン処理後の試料の分注では、後続の日において、ほとんどCODがないことが理解される。これは、初日のオゾン処理により全てのバイオマスが死滅し、それに伴って微生物活性が失われ、その後のCODの放出がほぼ0になったことを示唆した。第1セットの実験で得られた結果の数値を表2に示す。
これらの実験は、第1セットの実験を裏付けるため、および、4分、5分間適用についての不足するデータを完全にするために行われた。図5にみられるように、4分、6分間適用において、1日目のCODの放出にはそれほどの差はない。しかし、6分間適用では、時間とともにCODの放出の増加がみられた。この状況は、6分間適用は、より多くの生きたバイオマスを破壊したことを示唆している。4分間適用における残存するより多くの活性バイオマスにより、曝気の間より多くのCOD消費がみられた。
4分、6分間適用後の残存するバイオマスの安定化状態は、OCRデータを見ることによって評価した。これらのデータを表3に示す。この表にみられるように、すべてのフラスコにおける酸素消費速度は実験期間とともに減少していた。試験フラスコにおけるOCRは、対照フラスコと比較してはるかに遅い速度で進行した。特に、6分間適用のフラスコでは、実験後にはフラスコにバイオマスがほとんど残存していなかったため、最大の下落がここで観測された。フラスコ内に放出されたCODが生物学的に分解可能かどうかを決定するため、酸素の取り込みの速度が既知のバイオマス・シードを、4日間の各日において6分間のオゾン処理を行った試料の上清に加え、OCRを測定した。当該シードのdO/dt値は−0.0004 mg/hであり、当該シードが加えられた試料のdO/dt値は−0.0006 mg/hであったことから、6分間適用において放出されたCODは生物学的に分解可能であることが結論づけられた。
好気性消化は、とりわけリン処理プロセスに適用される、汚泥除去技術である。生物学的に吸収されたリンが再放出されないように、そのような汚泥は嫌気状態に晒すべきではない。本実験の結果、リンが豊富な汚泥が得られる場合、これは、副次的な目的に利用し得ることが結論づけられた。実験後において、CODだけでなく、リンもまた、培養液中に放出され得ることを考慮して、6分間オゾン処理された試料における総リンおよびオルトリンを実験後に分析した。1日目において、汚泥中の総リンは11,36 mg/Lと記録され、オゾン処理の後、オルトリンは3.6 mg/Lと測定された。初期には0.006 gのリンが単位グラムのバイオマスに存在しており、その後、この数値は、0.0082に増加した。このことから、オゾン処理の試験の間、それほどの量のリンは培養液中に放出されないことが理解される。
