国内外矿井水处理及资源化利用研究进展. (Chinese)

Domestic and foreign progress of mine water treatment and resource utilization. (English)

The treatment and resourceful utilization of mine water is an important thrust to achieve the dual goals of high-quality development of coal industry and ecological civilization construction in mining area. The decision to effectively treat and use mine water as an unconventional water resource will inevitably be made in the future due to the restrictions of a global water resource deficit and ecological environment protection. From the standpoint of the quality features of mine water in various mining sites, the formation mechanism and evaluation techniques of mine water quality were completely detailed here. Meanwhile, there were two stages in the establishment of mine water quality: water-rock interaction in aquifer and water-rock interaction in goaf. Additionally, systematically examined domestic and foreign characteristics of treatment systems for mine water containing suspended solids, highly mineralized mine water, acidic mine water and mine water containing special components. The new technologies for efficient cyclone purification of mine water including suspended solids, bipolar membrane and membrane distillation treatment of high-mineralized mine water, and built wetland treatment of acidic mine water were all vehemently discussed. The means of resourceful usage of mine water at home and abroad, including industrial production water, ecological water utilization, domestic water and heat energy utilization, were based on the summary of the current situation of mine water resource utilization at home and abroad. Finally, the problems and scientific considerations of mine water treatment and resource utilization in China’s coal mining areas are put forward, and concept of mine water treatment and resource utilization is established. Moreover, the technological research and development for treatment and resourceful utilization of mine water was promoted constantly to improve the comprehensive utilization rate of mine water resource, so as to solve the contradiction between supply and demand of water resources in coal mining area and realize the coordinated development of social and economic growth, exploitation of coal resource and ecological civilization construction of minin [ABSTRACT FROM AUTHOR]

煤矿区矿井水处理及资源化利用是实现煤炭工业高质量发展与矿区生态文明建设双重目标的 重要推力。在全球水资源短缺与生态环境保护的约束下，矿井水作为一种非常规水资源，其大规模 处理与高效利用是未来发展的必然选择。文中从煤矿区矿井水水质特征出发，全面论述了矿井水水 质形成机制与水质评价方法，并将矿井水水质形成划分为含水层水–岩作用和采空区水–岩作用 2 个 阶段。系统分析了国内外含悬浮物矿井水、高矿化度矿井水、酸性矿井水及含特殊组分矿井水处理 技术优缺点，重点阐述了含悬浮物矿井水高效旋流净化、高矿化度矿井水双极膜和膜蒸馏处理、酸 性矿井水人工湿地处理的新技术。在总结国内外矿井水资源化利用现状的基础上，阐明了矿井水资 源化利用的途径主要包括工业生产用水、生态用水、生活用水及热能利用 4 种。最后，提出了目前 我国煤矿区矿井水处理及资源化利用存在的问题及科学思考，建立了矿井水处理及资源化利用概念 模型，通过不断推进矿井水处理及资源化利用技术研发，提高矿井水资源综合利用率，解决煤矿区 水资源供需矛盾，促进社会经济增长、煤炭资源开发与矿区生态文明建设三者之间的协同发展。 [ABSTRACT FROM AUTHOR]
