摘要
重金属污染是世界各国面临的重大环境问题。随着有色金属产业升级,资源型城市及周边地区出现大面积的工业遗弃场地,存在极大的环境风险。针对我国有色冶炼工艺多样、地质条件复杂、污染溯源难等问题,对2002~2022年间发表的冶炼场地污染特征研究和工程修复案例进行系统分析。综述了有色金属冶炼场地的精细刻画、污染形成、污染传输、污染阻控等方面的研究进展;明晰土壤-地下水系统重金属的生物地球化学过程,厘清污染物在复杂水文地质条件下的迁移转化规律,探讨污染场地土壤-地下水协同修复技术耦合与策略制定;分析了重金属污染场地修复技术的优缺点,提出了有色冶炼场地土壤-地下水协同修复的主要研究方向,为工业遗弃场地的环境风险管控与重金属污染防治提供科学参考。
Heavy metal pollution is a major environmental problem worldwide.With the upgrading of the non-ferrous metal industry mode of production,large areas of abandoned industrial sites in resource-based cities and the surrounding regions pose significant environmental risks.Due to the complex history of non-ferrous smelting in China,special geological conditions,and difficult identification of heavy metal pollution source,this paper systematically reviewed the much kinds of literatures on pollution characteristics of non-ferrous smelting sites and practical engineering remediation cases published in the past 20 years.It summarized the nuanced characterization,pollution formation,transmission,and pollution prevention of non-ferrous smelting sites.Clarifying the biogeochemical processes of heavy metals in soil-groundwater systems,defining the migration and transformation rules of pollutants under complex hydrogeological conditions,and developing soil-groundwater collaborative remediation technologies and strategies formulation for contaminated sites faced the main challenges.The advantages and disadvantages of remediation technologies for heavy metal contaminated sites at home and abroad were respectively listed.The main research directions of soil-groundwater synergistic remediation of non-ferrous smelting sites were proposed to provide scientific reference for the redevelopment and safe utilization of industrial abandoned sites.
