CAREER: Chlorine Cycling in Electrochemical Treatment Systems

CAREER奖的核心愿景是，可持续废物处理技术的设计和操作必须以一种使用可再生能源推动废物处理过程的方式，将废物中的元素转化为对环境友好的形式。本项目研究方面的目的是验证一个假设，即在电化学处理含氯废物时产生的不良氯化副产物的数量和种类取决于反应器配置、阳极材料、阳极电位、施加电流和废物中氯与污染物的比例。苯酚将作为模型化合物，在全因子设计中，在不同的反应条件下，测量能量输入和苯酚、碳种、需氧量和氯种的变化。探索性数据分析和方差分析技术将应用于数据，以确定哪些参数，单独和相互作用，对电力消耗和不需要的氯化副产物的生产影响最大。本项目的教育目标是利用所获得的知识来提高公众和专业人士对以下方面的理解：1)基于元素循环方法的可持续工程解决方案；2)在比环境课程中通常探索的更广泛的背景下进行氯化学；3)适当使用电化学处理系统。

CBET- 0747602KupferleThe central vision for this CAREER award is that sustainable waste treatment technology must be designed and operated in a way that returns the elements in a waste to environmentally-friendly forms using renewable energy to drive the process. The objective of the research aspect of this project is to test the hypothesis that the amount and species of undesirable chlorinated byproducts produced in electrochemical treatment of chloride-bearing waste depend on reactor configuration, anode material, anode potential, applied current and chlorine-to-contaminant ratio in the waste. Phenol will be used as a model compound, and energy input and changes in phenol, carbon species, oxygen demand, and chlorine species will be measured as treatment proceeds under different reaction conditions in a full factorial design. Exploratory data analysis and analysis of variance techniques will be applied to the data to identify which parameters, individually and interactively, have the most impact on power consumption and production of undesirable chlorinated byproducts.The education objective of this project is to use the knowledge gained to increase public and professional understanding of1) sustainable engineering solutions based on an elemental cycle approach,2) chlorine chemistry in a broader context than typically explored in environmental curricula, and3) appropriate use of electrochemical treatment systems.
