Electrochemical waste water treatment

目标。该项目建议开发一种用于废水连续处理的电化学流-电解液。该装置将包含国际镍公司技术服务公司生产的商业金属泡沫。污染物的电化学降解(电氧化或电还原)将在泡沫电极上发生。我们将研究水溶液在金属泡沫中的渗透和流动。我们将与国际镍公司技术服务公司合作，设计和制造具有精心定制的3D结构、孔隙率的新型泡沫，并增强水溶液的电解液渗透性和流动性。为了将泡沫金属应用于所提出的电化学流-电解液反应器处理废水，需要对这些参数进行控制。经过优化后，它将用于电化学处理医院废水和地下水中常见的危险污染物。我们将培训两名学生和一名博士后，学习最先进的表面、材料、物理化学、分析化学仪器和电化学废水处理方法。我们将加强皇后服务公司和国际镍公司技术服务部门之间现有的联系。该项目设想对商业金属泡沫的三维孔隙率、微米和纳米结构进行详细研究。为了评估其在电化学设备中的长期性能，对金属泡沫的三维结构和性质的表征是必不可少的。最先进的研究工具的应用将使我们能够收集这些急需的结构和成分数据，并将它们传达给INCO技术服务部门。具有良好定制性能的金属泡沫将作为考虑到独特的环境和健康应用的新型电极材料进行测试。它们将被整合到电化学流-电解液反应器的原型中。最终产品有可能对加拿大非常有益，因为加拿大面临着与地表水、地下水和湖水污染有关的各种问题。

OBJECTIVES. The project proposes the development of an electrochemical flow-electrolyte for continuous treatment of waste waters. The device will incorporate commercial metallic foams manufactured by Inco Technical Services. The electrochemical degradation of pollutants (electro-oxidation or electro-reduction) will take place at the foam electrode. We will study the penetration and flow of aqueous solutions in metallic foams. Jointly with Inco Technical Services, we will design and fabricate new foams of well-tailored 3D structure, porosity, and enhance aqueous electrolyte penetration and flow. The control of these parameters is needed to apply metallic foams in the proposed electrochemical flow-electrolyte reactor for waste watertreatment. Following its optimization, it will be used in the electrochemical treatment of dangerous pollutants commonly found in hospital waste waters and ground water. We will train two students and a post-doctoral fellow in state-of-the-art surface, materials, physical-chemistry, analytical-chemistry instrumentation, and electrochemical waste-water treatment methods. We will strengthen the existing link between Queen's and Inco Technical Services.  SIGNIFICANCE. The project envisaged a detail study of the 3-D porosity, micro- and nano-structure of commercial metallic foams. Characterization of the 3-D structure and properties of the metallic foams is essential in order to assess their long-term performance in electrochemical devices. Application of state-of-the-art research tools will allow us to gather this much needed structural and compositional data, and tocommunicate them to Inco Technical Services. The metallic foams of well-tailored properties will be tested as new-type of electrode materials with unique environmental and health applications in mind. They will be incorporated in the prototype of an electrochemical flow-electrolyte reactor. The end-product has the potential of being very beneficial to Canada that suffers from a variety of issues related to the contamination of surface, ground and lake waters.
