铅锌尾矿重金属渗漏污染土壤和地下水的电动修复技术研究

Study on Electrokinetic Remediation of Heavy Metal Seepage Contaminated Soil and Underground Water from Lead-zinc Tailing

随着生产的发展,中国地下水重金属污染问题日益严重,特别是尾矿重金属渗漏污染地下水尤引人注目,地下水和土壤相互作用,导致重金属离子发生迁移和再分配。电动修复技术作为一种新兴绿色技术,因其高效、节能、成本低、无二次污染,具有很好发展前景。本文对土壤和地下水重金属污染电动修复技术的原理、实际研究应用、技术优势及缺点进行论述,为进一步研究铅锌尾矿重金属渗漏污染地下水电动修复技术提供理论依据。

Groundwater pollution caused by heavy metal is becoming more and more serious , especially for the heavy metal seepage contaminated underground water from lead-zinc tailing, which has attracted attentions frjom the whole world.The lead-zinc tailings would react with the underground water after they were stacked, which made the heavy metal transfer and distribute a-gain.The electrokinetic remediation technique is a new green technique , has broad development prospect for its high efficiency , economy and environmental functions.This paper sums up the research circumstance in abroad, introduce the elements, basic cir-cumstance predominance and disadvantage of electrokinetic remediation technique, developing theatrical basis for electrokinetic remediation technique of heavy metal seepage contaminated underground water from lead-zinc tailing in China.
