1) aeration/non-aeration ratio
曝停比
1.
To analyze the effect of DO and aeration/non-aeration ratio on the microbial community structure,active sludge and biofilm samples were taken from the SBBR one-step completely autotrophic nitrogen removal reactor under different DO concentrations and aeration/non-aeration ratios.
为研究溶解氧及曝停比对单级自养脱氮系统微生物群落结构的影响,从不同溶解氧水平及曝停比条件下的SBBR单级自养脱氮反应器中采集活性污泥及生物膜样品,进行PCR-DGGE及条带统计分析。
2) aeration on/off time
曝气/停曝时间
1.
The influence of the dissolved oxygen(DO) concentration and aeration on/off time on short-cut nitrification and denitrification were investigated.
本试验将反应器温度控制在30℃左右,采用间歇曝气的运行方式,研究了溶解氧浓度及间歇曝气/停曝时间对SMBR实现短程硝化反硝化脱氮的影响,同时研究了胞外聚合物各组分对膜污染状况的影响。
2.
To improve the total nitrogen (TN) removal efficiency of membrane bioreactor(MBR), dissolved oxygen (DO) and aeration on/off time were controlled to study the possibility of total nitrogen removal through short-cut nitrification and denitrification.
为了改善膜生物反应器(MBR)的脱氮效果,考察了不同溶解氧浓度(DO)、曝气/停曝时间对MBR工艺实现短程硝化反硝化生物脱氮的可能性以及对膜污染的影响。
3) aeration ratio
曝气比
1.
By means of single-factor test and double factors orthogonal test,better removal rate of COD,TN,and TP was obtained under the combined influence of aeration ratio and sludge retention time.
5h的条件下,曝气比和泥龄均高度显著地影响TP的去除,但曝气比的影响是泥龄影响的600倍。
4) exposure ratio
曝光比
5) ratio of effective exposure
有效曝光比
1.
The method introduces a light-proof board,and it has higher ratio of effective exposure,thus the frame rate is raised up to 400fps.
该方法将帧频提高到了400帧/秒,具有较高的有效曝光比,并进一步改善了图像的质量。
6) Blue/yellow exposure
蓝/黄比曝光
补充资料:变量曝气法
分子式:
CAS号:
性质:又称变量曝气(法)。是废水活性污泥法的一种改良型。为适应曝气池进水口至出水口之间混合液中有机负荷不同的需要,对曝气池的不同部分供给不同空气量,入口处供给空气量较多,出口附近则较少,使得空气量与混合液的需氧量大致成正比。此法可节省供氧量,不需设置初次沉淀池。
