查询词典 reactor

A submerged membrane sequencing batch bioreactor was used to treat coke wastewater.Long running performance showed that due to the membrane interception,the nitrobacter is enriched in reactor in the interest of improving the nitrification rate;the maximum ammonia nitrogen loading can be 0.19 kg/(m3·d) with effluent ammonia nitrogen＜1 mg/L (removal rate 99%).Long sludge retention time may result in the accumulation of metabolic products and high molecular materials,and thus inhibiting activity of nitrate bacteria and causing a ccumulation of NO2-,which is beneficial to the running of short-cut denitrif ication.However,too long retention time will affect the activity of nitrite bacteria,detrimental to the treatment effect of ammonia nitrogen.

采用浸没式膜生物反应器处理焦化废水的试验结果表明：膜的截留作用可使硝化菌在反应器内富集而有利于提高系统的硝化能力，其去除氨氮的最高负荷为0.19kg/(m3·d)，出水氨氮＜1mg/L(去除率为99%)；泥龄长可能使微生物的代谢产物或其他大分子物质积累，从而抑制硝酸盐细菌的活性，导致NO2-积累而有利于短程脱氮的进行，但泥龄过长也会影响亚硝酸盐细菌的活性，从而影响对氨氮的处理效果。

Long running performance showed that due to the membrane interception,the nitrobacter is enriched in reactor in the interest of improving the nitrification rate;the maximum ammonia nitrogen loading can be 0.19 kg/(m3·d) with effluent ammonia nitrogen＜1 mg/L (removal rate 99%).

焦化废水含氮量高且含有大量有毒和难降解物质，若采用传统生物处理工艺不但流程较长，处理效果也较难达到要求，而膜生物反应器通过膜分离强化了生物处理效果，克服了传统工艺的弊端［1］。

Nitrosification and denitrification in an artificial domestic wastewater with low COD were studied in a sequencing batch moving bed biofilm reactor.

在序批式移动床生物膜反应器内，对进水COD较低的条件下，模拟生活污水的亚硝化及脱氮性能进行了研究。

The most probable number measurement showed that the overwhelming quantity of nitrosobacteria immobilized on biofilm was the main reason for stable and high nitrite accumulation in the reactor.

最大可能计数法测定发现，亚硝化菌在数量上的绝对优势是反应器能始终保持高效稳定的亚硝氮积累的主要原因。

The sludge age in the reactor is large, so that nitrobacteria and nitrosomonas live together. The nitrogen removal via nitrite was possible mainly because the activity of nitrobacteria was inhibited rather than rushed out in number.

反应器内的污泥龄较长，硝酸菌和亚硝酸菌长期共存，发生短程硝化反硝化主要因为硝酸菌的活性受到抑制，而不是数量上受到淘汰。

By using the specific PCR primers and T-A cloning, two species of AOB, 1 species of NOB and 11 species of ANAMMOX were detected in the SBBR one-step completely nitrogen removal process. One of the AOBs dominated at this reactor belonged to the family of Nitrosomonas for the similarity of 98% while another one was almost the same with an uncultured one.

同时通过T-A克隆的方法，在系统中发现2类不同的AOB序列，一类与氨氧化菌标准菌株Nitrosomonas有98%的较高相似性，另一类则与其它一种未得到纯培养的AOB接近，相似性为99%。

But the effluent ammonium in the anoxic reactor, where enough NO2 present were present, was equal to the blank system, and no ammonium was converted to such nitrogen compounds as NO-2 and N2 by Nitrosomonas eutropha using NO2 as electron acceptor, which maybe caused by lack of the function bacteria.

但在足够NO2存在并且缺氧的条件下，单级自养脱氮系统内的出水氨氮浓度与空白反应器相当，NH+4并没有被亚硝化单胞菌以NO2为电子受体氧化为NO-2和N2等化合物而得以去除，可能是因为系统内不存在该类型的亚硝化功能菌。

But the effluent ammonium in the anoxic reactor, where enough NO2 were present, was equal to the blank system, and no ammonium was converted to such nitrogen compounds as NO2- and N2 by Nitrosomonas eutropha using NO2 as electron acceptor, which maybe caused by lack of the function bacteria. There were two ANAMMOX reaction pathways in the one-stage autotrophic nitrogen removal system. One way was that after part of NH4+ was oxidized to NH2OH under aerobic conditions, NH2OH and NO2- were converted to N2O under anaerobic conditions, at last N2O was further converted to N2 which realized the nitrogen removal; Another way was that at first NO2- was reduced to NH2OH, NH2OH reacted with NH4+ to form N2H4, which was further converted to N2 subsequently, realizing the nitrogen removal.

结果表明：单级自养脱氮系统内6.72%的氨氮是通过吹脱等物化作用去除的，不超过6.02%的氨氮是通过传统硝化反硝化途径去除的，87.26%左右的氨氮是由自养脱氮途径去除的，自养脱氮反应起主要脱氮作用；在足够NO2存在且缺氧的条件下，单级自养脱氮系统内的出水氨氮浓度与空白反应器相当，NH4+并没有被亚硝化单胞菌以NO2为电子受体氧化为NO2-和N2等化合物而得以去除，可能是因为系统内不存在该代谢功能的亚硝化功能菌；单级自养脱氮系统内存在两条ANAMMOX反应途径：其中一条途径即NH4+在好氧条件下被氧化为NH2OH后，生成的NH2OH与系统内的NO2-在缺氧条件下被转化为N2O，N2O则进一步被转化为N2而实现氮的去除；另外一条途径即NO2-首先被还原为NH2OH，生成的NH2OH则与系统内的NH4+反应生成N2H4，N2H4继续被转化为N2而实现氮的去除。

These bowl-shaped aggregates are promising candidates for nano reactor or drug carrier.4 2,7-dimethylene-1,4,6-trioxaspiro[4, 4]nonane with two vinyls was prepared to be used as electron-donor and crosslinker.

这些由聚电解质复合物自组装形成的聚集体，在微反应器和药物释放等领域具有潜在的应用前景。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
