中文拼音 [tuōdànlǜ]
脫氮率
英文

Study on nitrate - nitrogen removal and community analysis of denitrifying bacteria in downflow fixed - bed bioreactor
下流式固定床反應器中反硝化細菌類群及其脫氮效率分析A o pilot - scale nitrogen removal process treating domestic wastewater. the study of short - cut nitrification and denitrification
泥齡對反硝化除磷脫氮系統效率的影響分析When inadequate n was added, the chloroplast structure in mesophyll cell was damaged in ear leaf, the amount of carbohydrate decreased in mestome sheath, and excessive n - redistribution and n - transportation to grain from vegetative mass appeared, which resulted in earlier leaf senescence. excessive n application led to too high activity of nitrate reductase, excessive vigorous nitrogen metabolism and too much exhaustion of carbohydrate in ear leaf, which resulted in the lack of enough carbohydrate in the lower leaf, meanwhile, the expansive chloroplast grana lamellae in leaf mesophyll cell and starch grain without nuclear in mestome sheath cell was observed, which led to the decrease of chlorophyll content and photosythetic capacity in maize leaf, then the early senescence occured
氮肥用量不足導致穗葉葉肉細胞葉綠體結構性差，維管束鞘細胞碳水化合物累積減少，營養體氮素再分配率大而引起葉片早衰；而過量供氮則導致生長後期硝酸還原酶活性過高，氮素代謝過旺，消耗了大量碳水化合物，以致下位葉不能得到充足的碳水化合物供應而提早脫落，同時葉肉細胞葉綠體片層結構膨脹，呈「肉汁化」特徵，維管束鞘細胞澱粉粒大量消耗，無核澱粉粒出現，從而葉片葉綠素含量下降，光合能力降低而出現早衰。The problems of carbon source supply and sludge age control could be effectively solved in the processes by means of " one carbon source for two uses " and " two - sludge system ", meanwhile phosphorus and nitrogen can be removed with less oxygen requirements and sludge production
該工藝以其特有的「一碳兩用」和「雙泥系統」 ，有效解決了常規生物脫氮除磷工藝的碳源供求矛盾和泥齡控制問題，可同時獲得較高的除磷和脫氮效率，並具有所需曝氣量少，剩餘污泥排放量低等特點。Using this system, research on nox emission and burnout characters of the test facility are carried out. the results of influence on nox emission and carbon in fly ash by coal type, coal particle diameter, furnace temperature and excess air are reached through tests. then micronized coal reburning tests are processed, which show a remarkable effect results on nox reduction and burnout rate
通過大量的試驗，得出了煤種、煤粉細度、爐膛溫度和過量空氣系數等因素對nox排放和煤粉燃燼率的影響趨勢；並在此基礎上研究了超細粉再燃對脫氮效果和燃燼性能的作用，試驗結果表明超細煤粉再燃對降低nox排放和飛灰含碳量具有明顯的效果。According to the general process for sfs and the mechanism for represents several methods to improve the ability of removing nitrogen
參考國內外大量文獻資料，根據潛流式人工濕地的常規工藝和脫氮機理，本文總結並提出了一些提高污水氮去除率的方法。分享友人
