摘要
【目的】鲁西南地区煤炭基地长期面临生产用水短缺与高矿化度矿井水排放难题,矿井水直接排放不仅加剧水资源浪费,还对南四湖流域水质安全构成威胁。为实现矿区绿色可持续发展,亟须探索高效矿井水全盐量治理及资源化利用路径,满足严格的环保与资源循环利用要求。【方法】本文以高庄煤业有限公司矿井外排水除盐及综合利用工程为研究对象,采用“预处理+三级膜浓缩+MVR蒸发结晶”工艺,通过去除悬浮物与胶体、逐级提升盐分浓度和盐分分离,实现全盐量治理和资源化回收。【结果】该工艺技术成熟、运行稳定,经济合理,自动化程度高,水质变化适应性强,处理后矿井水满足排放与回用水标准。【结论】本工程有效实现高矿化度矿井水资源化利用,为同类矿井水全盐量治理提供了技术可靠、经济可行的实践范例。
[Purposes]Coal mining bases in southwestern Shandong have long faced dual challenges of production water shortages and the discharge of highly mineralized mine water.Direct discharge not only aggravates water resource wastage but also threatens the water quality safety of the Nansi Lake Basin.To achieve green and sustainable development in mining areas,it is imperative to explore efficient solutions for comprehensive salinity control and resource utilization of mine water,meeting stringent environmen⁃tal protection and circular economy requirements.[Methods]This study focuses on the desalination and comprehensive utilization project of mine water discharged from Gaozhuang Coal Industry Co.,Ltd.The"pretreatment+three-stage membrane concentration+MVR evaporation crystallization"process was adopted to remove suspended solids and colloids,progressively concentrate salts,and achieve separation,thereby realizing salinity control and resource recovery.[Findings]The process demonstrates mature technology,stable operation,cost-effectiveness,high automation,and strong adaptability to water quality fluctuations.The treated mine water complies with both discharge standards and reuse requirements.[Conclusions]This project successfully achieves the resource utilization of highly mineralizedmine water,providing a technically reliable and economically viable model for comprehensive salinity treatment in similar mine water applications.
