查询词典 COD

Reaction temperature, residence time had also primary influence on the oxidative decomposition of organic pollutants.

在这些影响因素中，选择合适的催化剂如Cu~(2+)和V_2O_5／γ-Al_2O_3等，均能较好提高有机物COD去除率；而改变温度、停留时间等操作条件正如常规的超临界水氧化技术一样，也对有机物氧化的COD去除率产生较大的影响。

结果表明，该垃圾场对地下水的污染极其严重：综合污染指数可达到59；单项污染组分如NO2-、NH4+、COD等普遍比参照值高出几十倍，致癌物质NO2-则高出340多倍。从水质的角度看，地下水中有的污染物(NO2-、NH4+、COD)已经超出地下水Ⅲ类水质标准数十倍甚至100多倍，到了不能饮用的程度。

The sum of BCOD of BODst test and XH measured through batch respirometer is consistent with the BCOD of BODlt test and the ratio between them was in the range of 0.88-1.02 with average 0.94. The BODlt test is time-consuming and the microorganisms'population and their metabolic characteristic are different from that of the actual activated sludge process. So the respirometry has the advantage of time-validity and representation for the actual activated sludge system.

6呼吸测量法测得的BCOD明显小于长期BOD测试方法的结果，这是由于后者得到的BCOD包括所有的活性微生物COD组分；短期BOD测试得到的BCOD与异养菌COD之和与长期BOD测试得到的BCOD比较接近，两者之比在0.88-1.02之间，平均值为0.94；长期BOD测试耗时长，测试用的微生物种群及其代谢类型都与实际活性污泥过程明显不同，因此，从测试结果的时效性和代表性方法考虑，短期BOD测试更具优势。

The cod brandade made its entry in the "nmoise" gastronomy only in the 18th century when cookers transformed the cod into a mash and grinded it with milk, olive oil and scrubland herbs.

尼姆厨师把鳕鱼剁成泥，捣碎与牛奶、橄榄油和一些南部石灰质荒地上生长的蔬菜相混合，经过精心烹调，尼姆奶油烙鳕鱼这道色香味俱全佳肴就呈现在我们面前。

It holds that for low concentration of wastewater effluent of the sugar mill,the relational line between BOD and COD can be obtained by applying the statistical method of linear regression on the series of data of the corresponding BOD and COD,once it can be determined.

认为对糖厂的低浓度废水：只要测定其对应的生化耗氧量和化学耗氧量的一组数据，通过直线回归法统计，便可得出这两者的关系直线

By practical tests, this paper reported the form design, sinker weight and making method of the truncated cone cod-end under current velocity of 0.45~0.75 m.s-1, and provided reference for cod-end making of deep-water net cage at strong current.

通过实物试验，报道了圆台形囊网在流速0.45~0.75 m.s-1时的外形设计、配重及制作方法，为强流下的深水网箱囊网制作提供参考。

There are some midst matters in wastewater, for removal of these matters the electrolyze time should exceed 30 min. The experimental results show that the bipolar packed bed cell has best treatment efficiency of phenol wastewater under condition that voltage is 10V, electrolyses time is 30 min, and velocity of flow is 1.03 cm/min.Basic on the study on treating of phenol wastewater, this paper carry on a research on treating of circuitry board film wastewater by bipolar packed bed cell.

本文在以上处理苯酚废水研究的基础上，论文研究了BPBC处理两种不同浓度得脱膜废水，试验结果表明，对于浓度较高的酸化气浮-光酚顿的出水，在外加氧化剂双氧水后，最佳处理工艺：槽电压8V，实际电解时间60min，双氧水的投加量为1倍理论药量，pH值为3，COD的去除率达到60%；在酸化气浮过程采用酸铜废液调节pH值将会降低COD的去除率。

Cod ( Gadus morhua L.) PRELIMINARY STUDY OF DIET OF PACIFIC COD, Gadus macroce Phalus Tilesius

的两个地理种群：苏格兰西海岸和波罗的海鲱、大西洋鳕 Gadus morhua L。

Norway sea water is cold and clean and rich of halobios. Norway cod lives in deep ocean in the Arctic Circle. The Norway cod nutrition is better for the excellent natural environment.

挪威海水温度低，海洋生物丰富，无污染，鳕鱼生长在北极圈深海中，得天独厚的自然环境使这种鱼的营养价值高出一筹。

It is the inoculable sludge, the peculiarity of wastewater and the framework configuration of the ABR that cause the predominant growth of acidogenic bacteria.(2) The complex containment was gradually removed by sort in the ABR, which showed the ABR has typical characteristics of the plug flow system. Along with the raising of the OLR, The gas yield and rate increase at the same time. The distribution of the gas yield and rate in the ABR is normal school along the way.

对ABR沿程的COD、VFA以及pH的变化规律进行分析，结果表明ABR对有机物的降解过程具有典型的推流系统特征，复杂污染物是以分类逐级的形式得以去除的；污染物的去除主要发生在1～3格室(COD去除贡献为50～80％)，随有机负荷的提高，去除主体逐渐后移；系统产气量及沼气产率均随有机负荷的提高而增加；处理红霉素废水时，格室产气量及产气率沿程呈正态分布，分析认为，这是由ABR的特性及废水本身的特点综合作用的结果。
