电子废物拆解场地复合污染土壤修复技术研究进展

Review on remediation technology of composite polluted soil in electronic waste dismantling site

电子废物拆解场地土壤中含有重金属、有机物等多种复杂污染物,对场地周围人群的健康与安全具有潜在威胁。概述了国内外复合污染土壤修复技术发展历程与研究现状,对比了化学修复、物理修复、生物修复技术在目标污染物、修复时间与修复效果上的差异,指出复合污染修复是未来研究的主要方向,修复技术将向多种技术联合应用发展、向绿色环保方向发展,后期应针对电子废物拆解场地土壤污染特征,开发出低成本、高效率、稳定性好、绿色安全的产业化技术。

Many kinds of complex pollutants remain in the soil of electronic dismantling site,including heavy metals,organic compounds and so on.As such,it has a potential threat to the health and safety of people around the site.In this paper,the overseas and domestic development and research status of remediation technology for heavy metals and organic complex polluted soil were summarized.Meanwhile,the differences of chemical remediation,physical remediation and bioremediation in target pollutants,remediation time and remediation effect were compared.It is pointed out that remediation of compound pollution was the main direction in the future,and the remediation technology would develop towards the joint application of various technologies and green environmental protection.Finally,based on the characteristics of soil pollution in electronic dismantling site,it is necessary to develop industrialization technology with low cost,high efficiency,good stability and green safety.
