摘要 酸性尾矿废弃地废石含有硫化物,在雨水的淋溶作用下会产出硫酸,加剧废弃地的酸化,增加企业环保成本,而生态修复工作就是从源头上控制废弃地的酸化。根据尾矿废弃地酸化机理,结合国内外最新研究进展,分析了生态修复技术现状;概述了隔离覆盖、改良剂改良、植物修复、微生物法等多种处理方法在实践中的适应性及优缺点,并分别介绍了隔离覆盖—植物修复技术、原位改良—植物修复技术在Reden煤矿、永平铜矿的成功应用案例。针对酸性尾矿废弃地的特点,单一处理方法具有较大的局限性,需要采用联合工艺进行治理,隔离覆盖—植物修复技术、原位改良—植物修复技术因见效快、效果好、操作简单,势必成为将来研究的主要方向。

Abstract: Sulfide is contained in the waste rock in abandoned acid tailing land,sulfuric acid is produced under the leaching of rainwater,acidification of the abandoned land is intensified,the enterprise environmental protection cost is improved.The acidification can be controlled fundamentally by ecological restoration work.According to the acidification mechanism of abandoned tailing land,combined with the latest study progress at home and abroad,the study status of ecological restoration is analyzed,the adaptability and advantages and disadvantages of the methods such as isolate coverage,improver modification,phytoremediation and microbial technique are discussed.Besides that,the application examples of the isolation coverage and phytoremediation technique and in—situ improvement and phytoremediation technique in Reden Coal Mine and Yongping Copper Mine are discussed.According to the characteristics of the abandoned acid tailing land,it is show that the shortcomings of the single methods is obvious,it is necessary to take integrated method to deal with the abandoned acid tailing land,isolation coverage and phytoremediation technique and in—situ improvement and phytoremediation technique can taken as the main study directions due to characteristics of less time consuming ,good effects and simple operation.
KeywordsAbandoned acid tailing land   Ecological restoration   Isolation coverage   In—situ improvement
