重金属污染土壤电动力学修复技术

电动力学修复技术是把电极插入受污染的土壤并通入直流电 ,发生土壤孔隙水和带电离子的迁移。土壤中的污染物质在外加电扬作用下发生定向移动并在电极附近累积 ,抽出处理从而被除去。新兴的电动力学原位修复技术去除土壤重金属污染正越来越多地被各国研究人员接受。一系列实验规模的研究和技术已日渐成熟 ,其中Lasagna技术和Electro klean技术已在美国肯塔基州和路易斯安那州等地进行了原位修复

Technology of electrokinetic remediation of heavy metals-contaminated soils

In the technology of electrokinetic remediation,we plug electrodes in soils and apply direct current,the water and electriferous ions in soils are moving toward the electrodes,so the pollutants in the soils are moving and cumulating around electrodes,then they are pump out and treated.Electrokinetic soil remediation is an emerging in suit technology and is accepted by many researchers and countries. A series of pilot scale studies and techniques are growing up, and the Lasagna and Electro klean processes have been carried out in Kentucky and Louisiana, USA.
