Reactive barriers for the remediation of fluoride contamination in groundwater

该项目将建立第一个中试规模的方解石渗透反应屏障，用于修复VAW铝厂地下水中的氟污染。在暴力侵害妇女问题上，氟污染地下水的浓度高达3000毫克/升，远远高于饮用水1.5毫克/升的指导值。屏障设计将基于之前SPIRT项目中VAW和CI的实验室工作，该项目表明方解石可以去除水中99%的氟化物污染。 该项目将在现场规模上证明该技术，并为其应用于其他污染物提供基础。

This project will build the first pilot scale calcite permeable reactive barrier for the remediation of fluoride contamination in groundwater at VAW aluminium. At VAW, fluoride has contaminated groundwater at concentrations up to 3000mg/L, levels far higher than the drinking water guideline value of 1.5mg/L. The barrier design will be based on laboratory work from a previous SPIRT project with VAW and the CIs which has shown that calcite can remove 99% of fluoride contamination from water. The project will prove the technology at the field scale and provide the basis for its application to other contaminants.
