摘要
采用原地浸矿法开采离子型稀土矿产生的尾水造成的流域性污染是一个亟待解决的问题。本文分析了流域性稀土矿尾水的主要特征及处理面临的困难,在借鉴传统生化法的基础上,提出了渗滤硝化与反硝化耦合除氮技术,系统介绍了该技术的原理特点、处理效果及工程应用情况,以期为我国流域性稀土矿尾水治理提供一条路径。
The watershed pollution caused by the tailwater generated by the in-situ leaching method for mining ionic rare earth minerals is an urgent problem that needs to be solved.This article analyzes the main characteristics of watershed rare earth mine tailings and the difficulties faced in their treatment.On the basis of drawing on traditional biochemical methods,a nitrogen removal technology has been proposed,which integrates infiltration nitrification and denitrification.The principle,characteristics,treatment effects,and engineering applications of this technology were systematically introduced,in order to provide a path for the treatment of rare earth mine tailings in China's watersheds.
