摘　　要：以广东省揭阳市普宁市南溪镇下尾张村、下尾王村垦造水田项目为例,探讨了汞金属污染土壤修复技术代替常规的化学结合客土物理改良技术、淋滤法修复技术、植物修复技术等的可行性及优越性,并详细研究了汞金属污染土壤修复技术应用于项目中的修复方案及施工工序。经改良后的土壤检测结果显示:项目区土壤重金属元素含量均低于《土壤环境质量农用地土壤污染风险管控标准(试行)》(GB 15618-2018)农用地土壤污染风险筛选值。可见该技术不仅能满足垦造水田项目土壤的修复要求,同时还能满足后期的循环利用。Taking the paddy field reclamation project in Xiaweizhang Village and Xiaweiwang Village,Nanxi Town,Puning City,Jieyang City,Guangdong Province as an example,the mercury metal contaminated soil remediation technology replaces the conventional chemical combined with the physical improvement technology and the leaching method remediation technology.The feasibility and superiority of phytoremediation technology,etc.,and the application of mercury metal contaminated soil remediation technology to the project’s remediation plan and construction procedures have been studied in detail.The improved soil test results show that the content of heavy metal elements in the soil of the project area is lower than the Soil Environmental Quality-Agricultural Land Soil Pollution Risk Control Standard(Trial)Agricultural Land Soil Pollution Risk Screening Value(GB 15618-2018).This technology can not only meet the soil restoration requirements of the paddy field project,but also meet the later recycling.
