BOD removalとは 意味・読み方・使い方

To solve a problem wherein, in sewage treatment using microorganisms, when the quality or quantity of flowing-in sewage varies, removal of organic matter (BOD), particularly nitrogen or phosphorus becomes unstable, and treatment performance (removal performance of the nitrogen or phosphorus) is resultantly degraded.例文帳に追加

微生物を利用した汚水処理では、流入する汚水の水質や水量が変動すると、有機物（ＢＯＤ）、とくに窒素やリンの除去が不安定になり、処理性能（窒素やリンの除去性能）が低下してしまう。 - 特許庁

To obtain stable treated water even in the case that the load of raw water fluctuates greatly as the operation control of a nitrogen removal system can be automated and a BOD (biological oxygen demand)/N ratio can be properly controlled.例文帳に追加

窒素除去システムの運転制御を自動化できると共にＢＯＤ／Ｎ比を適正に制御できるので、原水負荷が大きく変動する場合でも安定した処理水を得ることができる。 - 特許庁

To provide a method and a device for effectively treating waste water containing a high concentration BOD component or normal hexane extract components such as waste water from swinery or food industrial without pretreatment such as dilution or removal of the solid portion.例文帳に追加

養豚排水や食品工業排水など高濃度のＢＯＤ成分やノルヘキ成分を含む排水を、希釈や固形分除去などの前処理なしに、有効に処理する方法及び装置を提供する。 - 特許庁

Phosphorus-containing raw water 1 is introduced into an anaerobic tank 3 of a biological dephosphorization activated sludge treatment stage 2, and BOD (biochemical oxygen demand) removal and the absorption of phosphorus into dephosphorization bacillus are performed in the anaerobic tank 3 and an aerobic tank 4 communicated therewith.例文帳に追加

リンを含有する原水１を生物学的脱リン活性汚泥処理工程２の嫌気槽３に導入し、嫌気槽３及びそれにつながる好気槽４においてＢＯＤ除去と脱リン菌へのリン吸収を行わせる。 - 特許庁

To obtain treated water of high quality by efficiently performing denitrification, dephosphorization and the removal of BOD in a method for obtaining treated water by passing wastewater through a phosphorus release process, a denitrification process and an aeration process in this order in the presence of activated sludge to subject the same to solid-liquid separation treatment by an immersion membrane.例文帳に追加

廃水を活性汚泥の存在下にリン放出工程、脱窒工程及び曝気工程の順に通水し、浸漬膜による固液分離で処理水を得る方法において、効率的な脱窒、脱リン、脱ＢＯＤを行って高水質の処理水を得る。 - 特許庁

The excess or deficiency of organic substances as hydrogen donors of denitrification reactions is discriminated by the arithmetic unit 15 from the BOD/N ratio, which is a ratio of the estimated nitrogen load to the estimated organic load, and the operation of the nitrogen removal system is controlled from the discrimination result.例文帳に追加

そして、推定した窒素負荷推定量と有機物負荷推定量との比であるＢＯＤ／Ｎ比から、脱窒反応の水素供与体としての有機物量の過不足を演算機１５で判定し、判定結果に基づいて前記窒素除去システムを運転制御するようにした。 - 特許庁

As COD components, BOD components, and SS components present in the contaminated water can be coagulated and precipitated by the metallic coagulant and the radiation-crosslinked body, the dioxin removal and normal water purification treatment can be performed at the same time.例文帳に追加

また、汚染水中に存在するＣＯＤ成分やＢＯＤ成分やＳＳ成分なども金属系凝集剤と放射線架橋体によって凝集沈殿できるから、ダイオキシン類の除去と同時に通常の浄水処理も実現できる画期的な浄化処理方法が提供される。 - 特許庁

To provide a wastewater treatment apparatus and a wastewater treatment method to obtain treated water by solid-liquid separation by having wastewater pass through an anaerobic tank, oxygen-free tank, aerobic tank, and membrane separation tank in this order in the presence of activated sludge, wherein BOD removal, denitrification, and dephosphorization of the wastewater are highly carried out with a simple constitution with controlled equipment cost and operation cost.例文帳に追加

排水を活性汚泥の存在下に嫌気槽、無酸素槽、好気槽、膜分離槽の順に通水し、浸漬膜による固液分離で処理水を得る方法において、設備費及び運転費を抑えた簡単な構成でかつ、高度に排水中のＢＯＤ除去、脱窒及び脱リンを行うことができる排水処理装置及び処理方法を提供することを目的とする。 - 特許庁
