最初沈殿槽１からの初沈汚泥の引抜き量を、最初沈殿槽１で生じる初沈汚泥の全量に対し、初沈汚泥の除去率が２５％以下となるように制御するのが、好ましい。例文帳に追加

It is preferable that the amount of the initially precipitated sludge to be withdrawn from the initial-stage precipitation tank 1 is controlled so that the removal rate of the initially precipitated sludge becomes ≤25% of the total amount of the initially precipitated sludge to be generated in the initial-stage precipitation tank 1. - 特許庁

微生物を利用して下水など汚水中の有機物質を処理し、これにより発生した汚泥を引抜き処理する水処理系において、引抜いた汚泥に炭酸塩Ｊを添加して炭酸ガスを発生させ、汚泥を浮上分離する。例文帳に追加

In a water treatment system for treating an organic substance in sewage by utilizing microorganisms and drawing out the sludge generated by this treatment, a carbonate J is added to the drawn-out sludge to generate carbon dioxide to perform the floatation separation of the sludge. - 特許庁

活性汚泥の増殖を抑え、余剰汚泥の発生を防ぐことができ、汚泥の引抜き及び再処理の必要がない極めて効率が高い有機性廃棄物の処理方法を提供する。例文帳に追加

To provide an organic waste treating method in which an excess of sludge can be prevented from being generated by restraining activated sludge from propagating, drawing-out and retreating of sludge are unnecessary and organic waste can be treated with extremely high efficiency. - 特許庁

有機性の被処理汚泥１０を消化槽１２で嫌気的に消化処理する汚泥の消化処理方法において、消化槽１２から消化汚泥の一部を引抜き、この引抜いた消化汚泥１８を第１工程の酸化処理槽２０で予備的に酸化する。例文帳に追加

In a sludge digestion method for anaerobically digesting organic sludge 10 to be treated, in the digestion tank 12, a part of the digested sludge is pulled out from the digestion tank 12, and the pull-out digested sludge 18 is preliminarily oxidized in an oxidation tank 20 in a first process. - 特許庁

この方法によれば、廃水中のＢＯＤ濃度が低い場合においても、曝気槽２内へのＢＯＤ源の投入及び余剰汚泥の引抜きを不要とし、且つ膜モジュール５における膜の目詰まりを長期間にわたって防止できる。例文帳に追加

Even when the concentration of BOD in wastewater is low, the charging of the BOD source in the aeration tank 2 and the drawing-out of excess sludge are made unnecessary and the clogging of the membranes of the membrane module 5 can be prevented over a long period of time. - 特許庁

嫌気処理又は無酸素処理を汚水に施す最初の反応槽（嫌気槽７）の酸素，酸化性物質が増加し、その反応槽が還元状態から逸脱しそうになったときに、最終沈殿池１０の引抜き汚泥の返送量を多くすることにより最初の反応槽内の微生物濃度を高め、その反応槽内を還元状態に維持する。例文帳に追加

When oxygen and an oxidizing substance are increased in a first reaction tank (anaerobic tank 7) for applying anaerobic treatment or oxygen free treatment to sewage and the reaction tank is ready to deviate from a reducing state, the return amt. of the sludge drawn out of a final sedimentation basin 10 is increased to enhance the concn. of microorganisms in the first reaction tank to hold the reaction tank in a reducing state. - 特許庁
