In Situ Remediation of Salt-affected Soil Using Electrokinetics

电动力学土壤修复技术是一种新兴的土壤修复技术，在土壤质地优良方面取得了良好的效果。为了寻找需要更少的土壤移动、降低作业强度并最大限度地减少路程的新技术，我们的行业合作伙伴已将电动(EK)修复确定为一种使能技术，可以实现负责任和可持续的土壤和地下水修复。尽管这项技术在小规模上显示出了令人振奋的结果，但该公司的目标是优化技术，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补救，并论证受盐分影响的土壤是否存在可重复的处理趋势。**要实现的具体目标包括：**1)为大规模实施开发具有成本效益的EK修复技术，其中包括集成远程操作和监测系统；**2)评估土壤水分含量对EK修复效率的影响；以及**3)评估电动对土壤微生物种群的影响。**NAIT的四个研究中心将与该公司合作并合作实现这些目标。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，并通过最大限度地减少表层土壤干扰和消除受污染土壤的移动需要，减少目前做法所观察到的环境影响。该项目的跨学科性质将为所有NAIT和公司技术人员以及参与现场和实验室活动的学生提供激励和强有力的培训。研究成果还将通过关于土地补救和复垦的区域会议和研讨会广泛分享给实地从业者。

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
