Abstract

Looking back at over a decade of research by herself and her group, the author advocates the added value of gas phase measurements and the application of mass balances, as well as the synergetic benefits obtained when combining both. The increased application of off-gas measurements for greenhouse gas emission monitoring offers a great opportunity to look at other components in the gas phase, particularly oxygen. Mass balances should not be strictly reserved for modellers but also prove useful while conducting lab experiments and studying full-scale measurement data. Combining off-gas measurements with mass balances may serve not only to quantify greenhouse gas emission factors and aeration efficiency but also to follow dynamic concentration profiles of dissolved components without dedicated sensors and/or to calculate other unmeasured variables. Mass-balance-based data reconciliation allows for obtaining reliable and accurate data, and even more when combined with off-gas analysis.

废气分析和质量平衡对废水处理的协同作用我们的一些个人经验反思

作者回顾了自己和她的研究小组十多年来的研究成果，主张气相测量和质量平衡应用的附加值，以及两者结合所产生的协同效益。在温室气体排放监测中越来越多地应用废气测量，这为研究气相中的其他成分，尤其是氧气提供了一个绝佳的机会。质量平衡不应仅限于建模人员使用，在进行实验室实验和研究全尺寸测量数据时也很有用。将废气测量与质量平衡结合起来，不仅可以量化温室气体排放因子和曝气效率，还可以在没有专用传感器的情况下跟踪溶解成分的动态浓度曲线，和/或计算其他未测量的变量。基于质量平衡的数据核对可以获得可靠而准确的数据，如果与废气分析相结合，效果会更好。
