摘要
随着工业化和城市化进程的加速,土壤重金属污染已成为全球性的环境问题。本文综述了土壤重金属污染的成因、现状、危害以及当前有效的治理与生态修复方法。通过文献回顾和案例分析,探讨了化学修复、物理修复、生物修复及联合修复等多种技术手段的作用机理、优缺点及其在实际应用中的效果。研究指出,土壤重金属污染主要来源于工业排放、农业活动及交通运输等,其难以降解和累积特性对生态环境和人体健康构成长期威胁。针对这些问题,本文提出了综合性的治理与修复策略,旨在为土壤重金属污染问题的解决提供理论依据和技术支持。
With the acceleration of industrialization and urbanization,soil heavy metal pollution has become a global environmental problem.In this paper,the causes,status quo and hazards of soil heavy metal pollution,as well as the current effective treatment and ecological restoration methods were reviewed.Through literature review and case analysis,the mechanism,advantages and disadvantages of chemical repair,physical repair,biological repair and combined repair and other technical means are discussed.Soil heavy metal pollution mainly comes from industrial emissions,agricultural activities and transportation,and its difficult degradation and accumulation characteristics pose a long-term threat to the ecological environment and human health.In view of these problems,this paper puts forward a comprehensive treatment and remediation strategy,aiming at providing theoretical basis and technical support for the solution of soil heavy metal pollution.
