摘要
指出了复合污染土体工程隔离治理技术作为潼关金矿区土壤重金属修复和治理的核心技术手段,只有对其治理效果进行客观全面的评价,才能为此项技术在潼关金矿区以至其他类似地区的推广应用提供切实可靠的数据支撑和科学依据。在潼关金矿区治理项目区设置样点,通过样品采集、实验室样品分析获得了治理区一手数据,并通过单项污染指数法和内梅罗综合污染指数法对潼关金矿治理项目区土壤重金属进行了综合效果评价,研究结果表明:耕作层土壤中各种金属元素都达到了清洁水平,土壤质量属于一级安全状态,为工程推广应用提供数据支撑和科学依据。
As the core technology of soil heavy metal remediation and management in Tongguan gold mining area,only the objective and comprehensive evaluation of its governance effect can we promote this technology in Tongguan gold mining area and other similar areas.The promotion and application provide reliable and reliable data support and scientific basis.In this study,samples were set up in the project area of Tongguan gold mining area.Primary data of the control area were obtained through sample collection and laboratory sample analysis.Soil samples of Tongguan gold mine project area were analyzed by single pollution index method and Nemero integrated pollution index.The results showed that all kinds of metal elements in tillage soil have reached the level of cleanliness and the soil quality belongs to the first-grade safety status,which provides the data support and scientific basis for the popularization and application of the project.
