赣南稀土矿区地下水污染现状、危害及处理技术与展望

Present situation,hazard and treatment technology of groundwater pollution in rare earth mining area of southern Jiangxi

赣南稀土矿区由于受离子型稀土矿开采的影响,地下水污染严重。在查阅国内外相关文献的基础上,阐述了赣南稀土矿区矿山开采和原地浸矿导致的地下水稀土元素、三氮(离子态的氨氮、亚硝酸盐氮和硝酸盐氮)和硫酸盐污染现状,分析了该类型地下水污染的危害,总结目前已有的地下水修复方法并分析其应用局限性,提出适用于赣南稀土矿区的地下水污染治理思路。

The groundwater pollution in rare earth mining area in southern Jiangxi is serious due to the influence ofiontype rare earth ore mining. Based on related literatures both at home and abroad,the present situation of rareearth elements,ammoniaN,nitrateN,nitriteN and sulfate pollution caused by ore mining and insitu leaching inthe rare earth mining area of southern Jiangxi was expounded,the hazard of this type of pollution analyzed,and theexisting methods of groundwater remediation as well as their application limitations summarized. Finally,thegroundwater pollution control ideas suitable for rare earth mining area in southern Jiangxi were proposed,in order toprovide reference for local groundwater pollution control.
