中文摘要
土壤电修复是一项新兴的土壤修复技术,对细质土壤已显示出积极的效果。为了寻找需要更少的土壤移动、降低操作强度和最大限度地减少行驶距离的新技术,我们的行业合作伙伴已经确定了电动(EK)修复技术,该技术可以实现负责任和可持续的土壤和地下水修复。尽管该技术在小规模试验中显示出了良好的效果,但该公司的目标是优化该技术,使其在大规模实施时具有成本效益。本项目的目标是了解如何实施EK修复,并证明是否存在可重复处理盐渍土壤的趋势。**要实现的具体目标包括:**1)开发具有成本效益的大规模实施EK修复技术,包括远程操作和监测系统的集成,**2)评估土壤含水量对EK修复效率的影响,以及**3)评估电动力学对土壤微生物种群的影响。** NAIT的四个研究中心将与公司合作实现这些目标。EK技术的成功实施和优化将为加拿大的石油和天然气公司节省大量成本,并通过减少地表土壤干扰和消除污染土壤的移动需求,减少目前实践中观察到的环境影响。该项目的跨学科性质将为所有参与现场和实验室活动的NAIT和公司技术人员以及学生提供激励和强有力的培训。研究成果也将通过关于土地补救和复垦的区域会议和讲习班,广泛分享给实地从业人员
英文摘要
Soil remediation by electrokinetics is an emerging technology that has shown positive results for fine textured soils. In an effort to find new technologies that require less soil movement, reduce operational intensity, and minimize distances travelled, our industry partner has identified electrokinetic (EK) remediation as an enabling technology that may allow for responsible and sustainable remediation of soil and groundwater. Although the technology has shown promising results at small scale, the company aims to optimize the technology and make it cost-effective for large scale implementation. The goal of the present project is to understand how to implement EK remediation and to demonstrate if there is a repeatable treatment trend for salt-affected soil. **Specific objectives to be achieved include:**1) Development of a cost effective EK remediation technology for large scale implementation that includes integration of a remote operating and monitoring system,**2) Assessment of the effect of soil moisture content on the efficiency of EK remediation, and**3) Assessment of the impact of electrokinetics on soil microbial population.**Four research centres at NAIT will collaborate and partner with the company to achieve these objectives. The successful implementation and optimization of EK technology would allow for significant cost savings for oil and gas companies in Canada and reduce the environmental impact observed with current practices by minimizing surface soil disturbance and removing the need for movement of contaminated soils. The interdisciplinary nature of this project will provide stimulating and strong training for all NAIT and company technical staff and students involved in field and lab activities. Research findings will also be widely shared to field practitioners through regional conferences and workshops on land remediation and reclamation
