Research Progress on Remediation Technology of Mercury Contaminated Soil in the PVC Industry

  • 摘要: 聚氯乙烯行业将成为我国汞公约履约的最重要领域,相关产业生产、升级、腾退转型导致的汞污染地块潜在数量与风险巨大,需要提前开展相关修复技术储备和工程应用实践研究;通过调研总结我国聚氯乙烯行业产业特点、生产工艺导致的汞污染途径与风险特征,对国内外汞污染地块土壤修复常用的修复技术有固化稳定化、热脱附和土壤淋洗等;从污染源控制、污染扩散阻隔、污染土壤及地下水修复等多方面和技术特性、工程实施两个维度,选取修复技术指标,提出多层次构建修复技术筛选矩阵标准;以期为聚氯乙烯行业汞污染地块环境评估与修复提供技术参考。

     

    Abstract: The PVC industry is the most important field for the implementation of the mercury (Hg) convention in China. The potential number and risk of Hg contaminated plots caused by the transformation of production, upgrading and withdrawal of related industries is huge. So it is necessary to carry out the relevant remediation technology reserve and engineering application practice in advance. Based on the investigation for the characteristics of PVC industry in China, the ways and risk characteristics of Hg pollution caused by production process were summarized. The remediation technologies of Hg contaminated land at home and abroad were summarized. The common remediation technologies of Hg contaminated soil included solidification stabilization, thermal desorption and soil leaching. The Hg contaminated groundwater technologies included extraction treatment, in-situ stabilization and PRB. From the aspects of pollution source control, pollution diffusion barrier, contaminated soil and groundwater remediation and so on, the remediation technology screening index was selected, and the multi-level standard of remediation technology screening was constructed, in order to provide a technical reference for environmental assessment, remediation and prevention of Hg contaminated plots in PVC industry.
