Groundwater remediation through nanoparticle addition to a filtration system and subsequent groundwater treatment through electrolysis

地下水渗透到建筑物的地下部分可能导致诸如霉菌生成等问题，这代表着潜在的健康危害，以及洪水（通过地下水携带的固体物质在排水沟处的积累以及由此产生的地下水流阻抗），这可能代表着安全危害并使被淹没的空间无法使用。随着施工和随后的建筑占用成为重要的经济驱动因素，消除潜在的建筑运营问题非常重要。我们的工业合作伙伴Lisgar Construction已经确定、开发并实施了一种基于深层过滤的技术解决方案，以处理地下水渗透，他们希望对此进行改进。本提案中要探索的一种改进方法是在过滤床基质中添加纳米颗粒材料。纳米颗粒的加入可能有助于捕获地下水携带的额外的、更细尺寸的固体，而不会由于表面效应而阻碍流体流动。此外，在将地下水引入市政下水道系统之前，可能需要对地下水进行处理。为此，我们还建议增加一个电化学电池，以消除污染物，可能存在于地下水中，以unmonumally-approved水平。为了研究这种改进，将对过滤系统和电化学电池的整体性能进行实验研究。数值模拟也将与实验并行进行，以提供对过滤系统性能和行为的更深入了解，并开发一种设计工具，通过该工具可以应用过滤系统。

Groundwater penetration in subterranean sections of a building can lead to problems such as mould generation,which represents a potential health hazard, and flooding (through the accumulation of the solid material carriedby the groundwater at drains and resultant impedance of the flow of groundwater), which can represent a safetyhazard and render the flooded space unusable. With construction and subsequent building occupancy beingsignificant economic drivers, eliminating potential building-operation issues is important. Our industrialpartner, Lisgar Construction, has identified, developed and implemented a technical solution based on deep bedfiltration to deal with groundwater penetration, upon which they wish to improve.One means of improvement that is to be explored in this proposal is the addition of nanoparticulate material tothe filter bed matrix. The inclusion of nanoparticles may help in capturing additional, finer-sized solids carriedby the groundwater without hindering fluid flow due to surface effects. Furthermore, treatment of thegroundwater may be required prior to directing it through the municipal sewer system. To this end, we alsopropose the addition of an electrochemical cell to remove pollutants that may be present in the groundwater tomunicipally-approved levels. In order to study such improvements, experimental studies of the overallperformances of the filtration system and the electrochemical cell are to be undertaken. Numerical modellingwill also be performed in parallel with the experiments, in order to provide greater insight to the performanceand behaviour of the filtration system and also to develop a design tool by which filtration systems may beapplied.
