高矿化度矿井水井下深度处理与浓盐水封存技术研究

高矿化度矿井水的深度处理及零排放是西部地区煤矿企业面临的严峻问题之一。文章围绕灵新煤矿高矿化度矿井水处理工程,详细论述了“直滤系统+反渗透系统”深度处理工艺和浓盐水井下封存技术。相较于地面处理系统,矿井水井下处理系统不仅实现了井下污水零升井的目标,而且大幅降低了投资和运行成本。同时,利用采空区进行浓盐废水井下封存,也为矿井水处理零排放提供了一条新的路径。

Research on treatment of high salinity mine water and storage technology of concentrated brine

The deep treatment and zero discharge of high salinity mine water is one of the serious problems faced by coal mining enterprises in the western region. Focusing on the high salinity mine water treatment project in Lingxin Coal Mine, this paper discusses in detail the "direct filtration system + reverse osmosis system" advanced treatment process and concentrated saline underground storage technology. Compared with the surface treatment system, the mine water underground treatment system not only achieves the goal of zero-liter sewage in the underground, but also significantly reduces investment and operation costs. At the same time, the use of goafs for underground storage of concentrated saline wastewater also provides a new path for zero discharge of mine water treatment.
