摘要
美国土地管理局(BLM)废弃矿区项目已经在科罗拉多州西尔弗顿附近建造并正在运营Eveline矿山排水处理库，以研究高高山环境中酸性矿山排水(AMD)的创新被动处理技术。对几种材料进行了柱试验，以确定在拱顶中使用的处理介质。本案例研究探讨了将Bauxsol TM Acid B Extra™(氧化铝精炼副产物)与生物炭、豌豆砾石和多孔混凝土结合使用以降低AMD金属浓度的潜力。试验的目的是创建一种被动处理系统，该系统可以(1)降低废水中的金属浓度，(2)降低运营成本，(3)利用工业废水，(4)在基础设施空间有限的寒冷气候下运行。结果表明，Acid B Extra™与生物炭的组合获得了最佳的近期效果，Cd、Cu、Fe、Mn和Zn去除率>95%，Al去除率>60%，同时不会堵塞中试柱。
A COMBINATION OF ACID B EXTRA ™ AND BIOCHAR TO REDUCE METAL CONCENTRATIONS IN ACID MINE DRAINAGE 1
The Bureau of Land Management (BLM) Abandoned Mined Land Program has built and is operating the Eveline Mine Drainage Treatment Vault near Silverton, CO to investigate innovative passive treatment technologies for acid mine drainage (AMD) in high alpine environments. Column tests of several materials were conducted to determine treatment media to use in the vault. This case study examines the potential of combining Bauxsol TM Acid B Extra™ (an alumina refining by-product) with biochar, pea-gravel, and porous concrete to reduce AMD metal concentrations. The objective of the trial was to create a passive treatment system that (1) reduces metal concentrations in effluent waters, (2) reduces operational costs, (3) utilizes waste streams from industry, and (4) operates in cold weather climates with limited space for infrastructure. Results suggest that the combination of Acid B Extra™ and biochar achieved optimal near term results with >95% removal of Cd, Cu, Fe, Mn, and Zn, and >60% removal of Al, while not clogging the pilot test columns.
