矿井水处理技术研究进展

Research progress of mine water treatment technology

当前我国矿井水每年排放量巨大但利用率仅为35%。预计到2035年我国煤炭矿井水年排放量将稳定在60亿m 3左右。矿井水已成为一种长期存在的常规水源,如何实现高效低成本的矿井水处理显得尤为重要。简要概述了我国矿井水资源的现状和矿井水的主要类型,并从常规处理技术和非常规处理技术两方面重点分析了各类矿井水的处理技术工艺,并对矿井水处理技术的未来发展方向进行了展望。

Currently,the annual discharge of mine water in China is huge,but the utilization rate is only 35%.It is expected that the annual discharge of coal mine water in China will remain stable at around 6 billion m 3 by 2035.Mine water has become a long-standing conventional water source,and it is particularly important to achieve efficient and low-cost mine water treatment.This paper briefly summarizes the current situation of mine water resources and the main types of mine water in China,and analyzes the treatment technologies and processes of various types of mine water from two aspects:conventional treatment technology and unconventional treatment technology.It also looks forward to the future development direction of mine water treatment technology.
