酸性矿山排水被动处理方法研究进展

介绍了酸性矿山废水的产生及危害，以及国内外处理酸性矿山废水技术的最新进展，对酸性矿山废水（AMD）处理方法从主动处理技术和被动处理技术两方面进行了介绍，主动处理技术主要是中和法，此方法使用碱性化学物质（主要包括：石灰、石灰石、苏打、苛性碱、过氧化钙、氨等）中和AMD。被动处理方法是利用自然产生的化学物质和生物过程处理AMD，被动处理技术有：人工湿地，缺氧石灰沟，垂直流动系统（如连续碱度产生系统），转换井，石灰塘，可渗透反应墙法，石灰石过滤床（LSB），矿渣过滤床（SLB）和敞口石灰渠道。并将主动处理技术与被动处理技术的优缺点进行了比较。

The Passive Treatment System of Acid Mine Drainage Research Progress

This paper introduced the production and hazards of the Acid Mine Drainage （AMD） and the recent of AMD treatment technology at home and abroad was summarized. This paper introduced the AMD treatment technology in two aspects ： the active treatment system and the passive treatment system. The neutralization method is the main technology of the active treatment. This method uses alkaline chemical substances to neutralize acid in AMD. The passive treatment systems take advantage of naturally occurring chemical and biological processes to cleanse contaminated mine waters. The primary passive measures include constructed wetlands, Anoxic Limestone Drains（ALD）, Successive Alkalinity Producing Systems（SAPS）, diversion wells, limestone ponds, permeable reactive barriers, limestone leach beds, slag leach beds and Open Limestone Channels （OLC）. The advantages and disadvantages of active treatment system and passive treatment system were compared.
