predatory activityとは 意味・読み方・使い方

To provide a method and a device for biologically treating organic wastewater, in each of which a multistage activated sludge method employing the predatory activity of microorganisms is adopted to improve treatment efficiency, reduce the sludge volume and improve the treated water quality by giving priority to filtration-predatory microorganisms.例文帳に追加

微小動物の捕食作用を利用した多段活性汚泥法において、濾過捕食型の微小動物を優先させて、処理効率の向上及び汚泥の減容化と共に、処理水質の向上を図る。 - 特許庁

To provide a multistage active sludge process utilizing the predatory activity of small organisms, in which while maintaining the stable quality of treated water, further enhancement of disposal efficiency and reduction of the volume of excess sludge generated can be realized.例文帳に追加

微小動物の捕食作用を利用した多段活性汚泥法において、安定した処理水質を維持した上でより一層の処理効率の向上と余剰汚泥発生量の低減を図る。 - 特許庁

The treated water in the first biological treatment tank 1 is introduced into a second biological treatment tank 2, and, the remaining organic components are decomposed oxidatively, non-agglomerative bacteria are autolyzed and the volume of sludge is reduced by predatory activity of small organisms.例文帳に追加

第１生物処理槽１の処理水を、第２生物処理槽２に導入し、残存している有機成分の酸化分解、非凝集性細菌の自己分解及び微小動物による捕食による汚泥の減量化を行う。 - 特許庁
