residual nitriteとは 意味・読み方・使い方

To obtain water to be treated without residual nitrogen and having excellent water quality by carrying out nitrite nitrification in a nitrification tank and then denitrification.例文帳に追加

硝化槽で亜硝酸型硝化を行って、その後の脱窒処理により、残留窒素のない良好な水質の処理水を得る。 - 特許庁

The water to be treated having little residual nitrogen and excellent can be obtained by carrying out denitrification of this nitrified liquid with Anammox bacteria to roughly completely react the ammonia nitrogen and the nitrite nitrogen.例文帳に追加

この硝化液をＡＮＡＭＭＯＸ菌により脱窒処理することにより、アンモニア性窒素と亜硝酸性窒素とをほぼ完全に反応させて、残留窒素の殆どない良好な処理水を得ることができる。 - 特許庁

To obtain high-quality treated water containing a small amount of residual nitrogen from raw water containing ammonia nitrogen and nitrite nitrogen by denitrifying nitrate nitrogen generated in an ANAMMOX denitrification tank by heterotrophic denitrification microorganisms while maintaining activities of ANAMMOX (autotrophic denitrification) microorganisms without requiring strict chemical dosing control and condition control for biological denitrification carried out by the ANAMMOX microorganisms performing a denitrification reaction where ammonia nitrogen acts as an electron donor and nitrite nitrogen acts as an electron acceptor.例文帳に追加

アンモニア性窒素及び亜硝酸性窒素を含有する原水を、アンモニア性窒素を電子供与体とし、亜硝酸性窒素を電子受容体として脱窒反応を行うＡＮＡＭＭＯＸ微生物で生物脱窒するに当たり、厳密な薬注制御や条件制御を必要とすることなく、ＡＮＡＭＭＯＸ微生物の活性を維持した上で、ＡＮＡＭＭＯＸ脱窒槽内で生成した硝酸性窒素を従属栄養性脱窒微生物により脱窒することにより、残留窒素の少ない高水質処理水を得る。 - 特許庁

Nitrate nitrogen removal treatment 4 for removing nitrate nitrogen and nitrite nitrogen in the effluent 2 in the regeneration of an anion exchange resin and sulfate ion removal treatment 10 for removing sulfate ions in the effluent are carried out and the resultant treated effluent 14 containing residual chloride ions is utilized for regenerating the anion exchange resin.例文帳に追加

アニオン交換樹脂の再生排液２中の硝酸性窒素及び亜硝酸性窒素を除去する硝酸性窒素除去処理４と、再生排液中の硫酸イオンを除去する硫酸イオン除去処理１０とを実施した後、塩化物イオンが残留し、硝酸性窒素、亜硝酸性窒素及び硫酸イオンが除去された処理液１４をアニオン交換樹脂の再生に利用する。 - 特許庁

In a nitrification-denitrification treatment method, a nitrite forming nitrification reaction is carried out in raw water in the presence of ammonia oxidizing bacteria while keeping dissolved oxygen in the raw water at a low concentration, COD degrading bacteria are controlled by blocking due to the concentration of accumulated nitrous nitrogen, and after nitrification, nitrous nitrogen formed in the nitrifying step is denitrified by the action of denitrifying bacteria with residual COD components as electron donors.例文帳に追加

原水中の溶存酸素を低濃度に保持しながら、アンモニア酸化細菌の存在下に亜硝酸型硝化反応を行うと共に蓄積した亜硝酸性窒素の濃度阻害によりＣＯＤ分解細菌を抑制して硝化処理した後、硝化工程で生成した亜硝酸性窒素を、残留するＣＯＤ成分を電子供与体として脱窒細菌の作用により脱窒する硝化脱窒処理方法。 - 特許庁
