广西某重金属污染场地固化/稳定化治理工程实例

Case Project of Stabilization/Solidification of Heavy Metal Contaminated site in Guangxi

介绍了广西河池市某重金属污染场地治理工程,包括场地污染现状、修复工艺分析、污染土壤修复过程。该工程采用了异位固化/稳定化工艺治理受砷、铅、镉、锌复合污染土壤7971 m^3,修复后的土壤进行填埋处理。该工程的成功实施证明了所采用修复技术的有效性,可为其他同类工程项目提供借鉴和参考。

This paper introduced an on-site treatment and remediation project of a heavy-metal contaminated site in Hechi, Guangxi Province. This project included pollution state of the site, analysis of remediation technology, remediation of heavy-metal contaminated soil. To prevent the spread of the pollutants, about 7971 cubic meters of soil contaminated by arsenic lead, cadmium and zinc have been remedied by the combined technologies of ex-situ Stabilization/Solidification and landfill. After the remediation, the soil was disposed by safe landfill. The success of the project implementation proved the engineering technology to be correct and effective, which can provide references for similar projects.
