矿山酸性废水处理技术现状及进展

Development and Status of the Treatment Technology for Acid Mine Drainage

矿山酸性废水(AMD)因其酸度大,同时还含有铜、铅、锌、镉等重金属离子,对环境危害极大。分析了矿山酸性废水产生的主要原因及其危害,总结了目前处理AMD常用的工艺技术方法,并对各种方法的基本原理及其优缺点进行了分析。简要介绍了国内外在矿山酸性废水治理领域出现的一系列新的处理技术,进一步阐述了国内外废水处理技术的研究进展及发展趋势,提出了发展高效、廉价、安全及操作简便的酸性矿山废水处理技术的必要性和必然性。

Acid mine drainage （AMD） is of great harm to the environment as it contains rich heavy metal ions such as Copper, Lead, Zinc, and Cadmium. The main causes and harms of AMD is analyzed, and the techniques cur- rently used to treat AMD is summarized and their advantages and shortcomings are analyzed. Moreover, the re- search progress and development trend of treatment technology for AMD in China and abroad are presented through a brief introduction of new treatment technologies. The necessity and inevitability of developing efficient, low-cost, safe and convenient treatment technology are expounded.
