To provide a method for removing nitrate nitrogen from soil seeping water, capable of being adapted to a wastewater soil seeping treatment plant necessary for aerobically keeping the surface layer of a plowed field or soil over a depth range of several ten cm and capable of efficiently and simply performing denitrification without providing a structure.例文帳に追加

畑や土壌表層数十センチを好気性に保つ必要のある排水土壌浸透処理場に適用することができ、構造物を設けることなく、効率よく簡便に脱窒を行なうことが可能な、土壌浸透水からの硝酸態窒素の除去方法を提供する。 - 特許庁

In this advanced sewage treatment by a step flowing-in type multistage nitrification denitrification method of dividing into non-oxygen tanks 2, 4 and aerobic tanks 3, 5, an amount of a part of initial settling sludge drawn out of an initial settling basin 1 of a sewage treatment plant to be charged to the non-oxygen tanks is controlled.例文帳に追加

無酸素槽２，４と好気槽３，５に分けるステップ流入式多段硝化脱窒法による高度下水処理において、下水処理場の最初沈殿池１から引抜かれる初沈汚泥の一部を無酸素槽に投入する量を制御する。 - 特許庁

To provide a catalyst regeneration method and a catalyst regeneration facility, which are capable of reducing treatment cost by using an existing facility installed in an exhaust gas treatment facility of an incineration plant without requiring an expensive complex facility constitution and capable of regenerating catalyst by heating without removing catalyst from a denitrification apparatus.例文帳に追加

複雑で設備コストのかかる構成を要することなく、焼却施設の排ガス処理設備に既に設置されている設備を用いて処理コストを低減でき、それでいて触媒を脱硝触媒装置から取り外すことなく、触媒の加熱再生を可能にする触媒再生方法と触媒再生設備を提供する。 - 特許庁
