Progress on desalination technology of high salinity mine water
Coal mining inevitably leads to the generation of a substantial volume of mine water,with the proportion of high salinity mine water progressively increasing. Research on the treatment and utilization of high salinity mine water is essential to mitigate the ongoing challenge of coal mine water scarcity and enhance the standards of eco-friendly mine construction and cleaner production. This paper delineated the deep desalination process of the zero-discharge treatment approach for mine water. The problems associated with the extended process flow, significant energy consumption, and elevated costs of the treatment system were outlined. Additionally, a comparative analysis of current and prospective treatment technologies in the desalination was conducted. The membrane concentration process was examined, introducing enhanced technologies derived from traditional reverse osmosis, forward osmosis, and membrane distillation. Regarding salt separation and crystallization, the paper compared eutectic freezing technology, supercritical desalination technology, humidification-dehumidification technology, and photothermal desalination technology. Through a comprehensive evaluation of existing and potential technologies for high salinity mine water treatment, the paper provided insights guiding the development of effective treatment technologies. The objective was to facilitate the large-scale, cost-effective, and efficient treatment of high salinity mine water, addressing the escalating challenges associated with high salinity mine water in the coal mining process and fostering the sustainable development of the coal industry.
