查询词典 bod

The results showed that the sludge settled properly at a influent BOD/P of 100/0.8. When the BOD/P was 100/0.6 and 100/0.3 respectively, an excessive growth of viscous Zoogloea with high moisture content was observed and non-filamentous bullring occurred. When the value of influent BOD/P was 100/0.4, more serious non-filamentous bulking occurred. Furthermore, under the condition of phosphorus deficiency the effect of microorganism on the nitrogen and phosphorus sources utilization rate were also studied in the experiments.

结果表明在进水中BOD/P为100/0.8以上的条件下，污泥的沉降性能良好；当进水中BOD/P分别为100/0.6和100/0.3时，出现高含水率的黏性菌胶团过量生长的现象，发生非丝状菌膨胀；在进水中BOD/P为100/0.4的条件下，发生更严重的非丝状菌膨胀，试验中还研究了磷缺乏条件下微生物对氮源和磷源利用率的变化。

The comparison between the obtained EC50 values and toxicity data from the literature points out the good agreement between the BOD bottle test (Raphidocelis su.) and those of nine widely used test methods, i.e., Fathead minnow, Vibrio fi., Microtox, Polytox, Spriotox, Shk1, Activated sludge, Daphina ma. and Tetrahymena. In this study, log Kow values of narcosis Ι compounds (using the BOD bottle test and nine bioassays) were reported.

实验中选定DO观测终点所求得的毒性数据与其他物种进行回归分析，回归结果则皆呈现高度相关（R2值≧0.84），这可推论出藻类与其他物种的分析方法（不含Nitrosomonas）的致毒机制有很高的相关性，且可知本试验方法不仅敏感性高且与其他的物种且有良好的相关性可做为替代性试验。

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

An organically modified silicate-PVA as an immobilization material for Hansennula anomala was investigated to develop an optochemical BOD sensor for the determination of BOD.
