稀土尾砂治理的研究进展

【摘要】 通过整理前人对稀土尾砂治理的研究发现,具体的方法主要有两种:物理和化学方法的再利用、生物性的植物恢复和土壤修复。前者在我国还属于初步研究阶段,技术有待提高;后者则是通过在尾砂中恢复植被,进而增加土壤中的有机质和降低重金属的含量,改善土壤性状,减少水土流失。更多还原

【Abstract】 The author had accessed to previous reports on the rare earth tailings treatment and found two mainly specific methods:reused by physical and chemical methods,biological plant recovery and soil remediation. The former in our country belonged to the initial stage of research,which of technology needed to be improved;the latter could increase soil organic matter and the reduction of heavy metal content by restoring vegetation in the rare earth tailing,then improve the properties of the soil,reduce water loss and soil erosion.更多还原
