primary sewage sludgeとは 意味・読み方・使い方

To enhance sludge thickening efficiency to excess sludge successively increasing in its amount and recovery efficiency thereof in stages of a secondary treatment and primary treatment of a sewage treatment.例文帳に追加

汚水処理の二次処理や一次処理の段階で、逐次増量する余剰汚泥に対する汚泥濃縮効率とその回収効率を高める。 - 特許庁

This sewage treatment method is constituted in such a manner that the livestock waste water is sent to a primary treatment tank, pretreated and subsequently treated by membrane while being subjected to activated sludge treatment in a secondary treatment tank, the excess sludge in activated sludge is pumped and sent to a sludge concentrating storage tank.例文帳に追加

方法的には、畜産排水を一次処理槽へ送り込んで前処理し、それを二次処理槽で活性汚泥処理しながら膜処理し、活性汚泥中の余剰汚泥を汲み上げて汚泥濃縮貯留槽へ送り込む。 - 特許庁

At this time, primary treated sewage in the primary treatment tank is treated by filtration while being separated by sedimentation, therein, the primary treated sewage which is treated by filtration is transferred to the secondary treatment tank and, at the same time, the deposited sludge which is settled is pumped and sent to the sludge concentrating storage tank.例文帳に追加

その際、一次処理槽の一次処理汚水を沈殿分離しつつ濾過処理し、その内、濾過処理した一次処理汚水を二次処理槽へ移流すると共に、沈殿した堆積汚泥を汲み上げて汚泥濃縮貯留槽へ送り込んでいる。 - 特許庁

To provide a method for producing ethanol from sewage sludge capable of efficiently producing ethanol by using fibers abundantly existing in the sewage sludge of a primary settling tank.例文帳に追加

最初沈殿池汚泥に豊富に含まれている繊維分を利用してエタノールを効率的に生産することができる下水汚泥からのエタノール生産方法を提供すること。 - 特許庁

To provide a method for treating sewage having a small generation amount of flocculated sludge in primary treatment of the sewage and capable of obtaining treated water having an excellent water quality.例文帳に追加

下水の一次処理において凝集汚泥の発生量が少なく、かつ良好な水質の処理水を得ることができる下水の処理方法を提供する。 - 特許庁

Ethanol is produced from sewage sludge by selectively separating fibers from the primary settling tank sludge generated from an installation to biologically treat organic waste water such as sewage with activated sludge or sludge gravitationally separated in the preceding step of the corresponding biological treatment step, subjecting the separated fibers to saccharification treatment and biological conversion treatment and carrying out the distillation of ethanol.例文帳に追加

下水等の有機性汚水を活性汚泥により生物処理する施設から発生する最初沈殿池汚泥若しくはそれに相当する生物処理工程の前工程で重力分離される汚泥から繊維分を選択的に取り出し、糖化処理、生物変換処理の後、エタノール蒸留を行い、エタノールを生産する。 - 特許庁

The apparatus for treating combined sewage is provided with equipment for subjecting effluent of a primary settling tank in the apparatus for treating combined sewage to coagulation separation, a flow path for discharging one part of the coagulation separation treated water to the public water area and a flow path for causing the remaining part of the coagulation separation treated water to flow into an activated sludge treating tank.例文帳に追加

合流式下水処理施設における最初沈殿池の流出水を凝集分離する設備と、該凝集分離処理水の一部を公共水域に放流する流路を設け、凝集分離処理水の残部を活性汚泥処理槽に流入させる流路を配備したことを特徴とする合流式下水の処理装置。 - 特許庁
