Investigation hybrid electrokinetic methods for soil, sediments and wastewater treatment

本研究的目的是在以下电动力学研究项目中探索解决环境和公共卫生问题的新应用：1)污泥和废水的EK深度处理，2)危险废物的EK能量回收，3)酸性硫酸盐土壤的EK控制过程，4)棕地和工业处置场地的EK修复。第一个项目的结果将对初级处理的植物或生物过程效率低的植物的升级特别有用。对知识的贡献可能对加拿大废水/污泥管理的现行立法产生影响。第二个项目将致力于开发从含油废物中提取有机液体馏分并同时去除金属的技术，以便将其作为一种清洁可持续的新燃料进一步应用。预计所提出的研究将导致工业污泥的振兴。第三个方案领域的结果将产生重要影响，因为它们将导致：a)开发允许保护基础设施的原位修复技术；b)为AMD和ASS开发专用排水系统；c)产生的知识将应用于针对ASS和AMD的新补救措施的高级研究。第四个项目涉及EK与其他过程相结合的应用，以推进知识和开发含有有机和无机污染物的棕地修复的新方法。预计该方法将直接应用于：a)有石油污泥的池塘，b)在污染区域周围形成自然屏障以清理径流，c)在沟渠中形成带状以收集径流，d)进入农田。然后，城市地区的棕地和污染场地的影响将会消失，公众健康将会得到改善。

The objective of the proposed research is to explore new applications in solving environmental and public health problems, in the following electrokinetic research programs: 1) EK advanced treatment of sludge and wastewater, 2) EK energy recovery from hazardous waste, 3) EK control processes in acidic sulphate soils, 4) EK remediation of brownfields and industrial disposal sites. The results from the first program will be particularly useful for upgrading the plants with primary treatment, or plants having a low efficiency of biological processes. The contribution to the knowledge might have an impact on current legislations on the management of wastewater/sludge in Canada. The second program will to the development of technologies that will permit on extractions of organic liquid fractions and simultaneous metal removal from oily waste in order to its further application as a clean sustainable New Fuel. It is expected that the proposed research will result a revitalization of industrial sludge. The results from third program area will have an important impact, since they will lead to: a) development of in-situ remediation techniques permitting the protection of infrastructures; b) development of special drainage systems for AMD and ASS; c) generated knowledge that would be applied to advanced research on new remediation actions for ASS and AMD. Fourth program deals with an application of EK combined with other processes to advance the knowledge and develop new methods for the remediation of brownfields containing organic and inorganic pollutants. It is expected that the methodology will find a direct application: a) to ponds with petroleum sludge, b) in the formation of natural barriers around contaminated areas for cleanup of runoff, c) in the formation of strips in ditches for runoff collection, and d) into landfarming areas. Then, the impact of brownfields and contaminated sites within urban areas will deplete, and public health will improve.
