| description | The invention belongs to the technical field of environmental protection and particularly relates to a method for repairing heavy metals in tailings by attapulgite clay. The attapulgite clay is addedinto the tailings by an adding amount of 5%-15% of the weight of the tailings, and the attapulgite clay and the tailings are stirred completely and uniformly until the content of heavy metals in the tailings is consistent with a heavy metal background value of soil with the tailings. The method is mainly used for in-situ remediation of the heavy metals in the tailings. Compared with a neutralization method, an electrochemical method, an isolation method, a biological treatment method and the like, the method has advantages of simplicity in operation, easiness in construction and low cost and can be applied to large-area tailing remediation.
本发明属于环境保护技术领域，具体涉及种使用凹凸棒石黏土修复矿尾中重金属的方法。本发明是向尾矿中添加凹凸棒石黏土，充分搅拌均匀，所述的凹凸棒石黏土的添加量占尾矿重量5％～15％，直到尾矿中重金属含量与尾矿所在地土壤的重金属背景值致。本方法主要是对尾矿中的重金属进行原位修复，该方法相比中和法、电化学法、隔离法、生物处理法等，具有操作简单，容易施工，成本低 |
