Description
図1は、本発明の散気装置を示す模式図である。本発明の散気装置1は、ガス供給手段2と散気用給気配管3(ヘッダー管)とを備える。ガス供給手段2より供給された空気は、散気用給気配管3から排出手段6を通して散気板4に送気され、散気板4の散気面に点在する複数の散気孔から放出される。
本発明の散気装置は、ブロー水供給手段5からブロー水を散気板4に定期的に供給することによって、散気装置を水面上に引き上げることなく、散気孔に付着した微生物を除去することができる。ブロー水の供給頻度に特に制限はないが、好ましくは数時間から数日毎にブロー水を散気用給気配管3内に供給する。
孔形状 :長さ1.45mm、幅0.04mm
開孔率 :約0.5%
通気量 :30m3/m2/hr
ブロー水 :次亜塩素酸ナトリウム溶液(濃度;100ppm)
ブロー水量:500ml/回
水ブロー頻度:1回/日
なお、水ブローを実施しない例を比較例とした。
Claims (4)
- 曝気槽内に配置されて散気用給気配管から空気の供給を受けて気泡を放出する散気板と、前記散気用給気配管内へブロー水を供給するブロー水供給手段と、
上端が前記散気板に連接され、下端が傾斜した吸い込み面を有するとともに前記散気用給気配管内に内挿されて前記散気用給気配管内に供給されたブロー水を前記散気板から排出する内挿管とを備えたことを特徴とする散気装置。 - 前記内挿管が、管壁に通気孔を有することを特徴とする請求項1に記載の散気装置。
- 前記ブロー水を前記散気板に定期的に供給することを特徴とする請求項1または請求項2に記載の散気装置の運転方法。
- 前記ブロー水が、微生物を死滅させる効果を有する成分を含む請求項3に記載の運転方法。
