Aiming at the water quality characteristics of low uranium concentration, high sulfate and high suspended solids in the seepage water of a decommissioned uranium mine in southern China, as well as the problems of unstable treatment effect, easy saturation and hardening of resin, and high operation and maintenance costs in the original resin adsorption uranium removal process, combined with the seasonal dynamic change law of uranium occurrence state under the background of the mine's karst landform, the analysis of seepage water quality characteristics and the optimization of treatment process were carried out. On the basis of finding out the cyclic mode of uranium "activation and migration in rainy season, local enrichment in dry season" and the difference of occurrence states in winter and summer, a seasonal combined treatment scheme of iron-based permeable reactive barrier (PRB) was proposed, and the process flow design, engineering facility planning and seasonal process parameter optimization were completed. The designed treatment capacity of the project is 400 m3/d, which can adapt to the seasonal fluctuation characteristics of the seepage water volume and uranium occurrence form of the mine, with an expected operation cycle of 10 years, and the materials can be recycled after regeneration. The application results show that the process has a significant removal efficiency for radioactive pollutants such as natural uranium, 226Ra, 210Pb and 210Po, the effluent water quality meets the standard stably for a long time, which can provide technical reference and engineering demonstration for the seepage water treatment of similar decommissioned uranium mines in karst areas.

中国南方某退役铀矿山渗出水具有低铀浓度、高硫酸根、高悬浮物的水质特征,使用原有树脂吸附工艺除铀时存在处理效果不稳定、树脂易饱和板结、运维成本高等问题。针对该问题,结合矿山喀斯特地貌背景下铀赋存状态的季节性变化规律,开展了渗出水水质特征分析与治理工艺优化研究。在探明铀“雨季活化迁移、旱季局部富集”循环模式及冬夏季赋存状态差异的基础上,提出铁基可渗透反应墙(PRB)分季节组合处理方案,并进行了工艺流程设计、工程设施规划及分季工艺参数优化。该工程设计处理量400 m3/d,可适配矿山渗出水水量与铀赋存形态的季节性波动特征,预计运行周期达10年,材料再生后可循环使用。应用结果表明,该工艺对天然铀、226Ra、210Pb、210Po等放射性污染物去除效率显著,出水水质长期稳定达标,可为同类型喀斯特地区退役铀矿山渗出水治理提供技术参考。

中国南方某退役铀矿山渗出水具有低铀浓度、高硫酸根、高悬浮物的水质特征,使用原有树脂吸附工艺除铀时存在处理效果不稳定、树脂易饱和板结、运维成本高等问题。针对该问题,结合矿山喀斯特地貌背景下铀赋存状态的季节性变化规律,开展了渗出水水质特征分析与治理工艺优化研究。在探明铀“雨季活化迁移、旱季局部富集”循环模式及冬夏季赋存状态差异的基础上,提出铁基可渗透反应墙(PRB)分季节组合处理方案,并进行了工艺流程设计、工程设施规划及分季工艺参数优化。该工程设计处理量400 m3/d,可适配矿山渗出水水量与铀赋存形态的季节性波动特征,预计运行周期达10年,材料再生后可循环使用。应用结果表明,该工艺对天然铀、226Ra、210Pb、210Po等放射性污染物去除效率显著,出水水质长期稳定达标,可为同类型喀斯特地区退役铀矿山渗出水治理提供技术参考。

Aiming at the water quality characteristics of low uranium concentration, high sulfate and high suspended solids in the seepage water of a decommissioned uranium mine in southern China, as well as the problems of unstable treatment effect, easy saturation and hardening of resin, and high operation and maintenance costs in the original resin adsorption uranium removal process, combined with the seasonal dynamic change law of uranium occurrence state under the background of the mine's karst landform, the analysis of seepage water quality characteristics and the optimization of treatment process were carried out. On the basis of finding out the cyclic mode of uranium "activation and migration in rainy season, local enrichment in dry season" and the difference of occurrence states in winter and summer, a seasonal combined treatment scheme of iron-based permeable reactive barrier (PRB) was proposed, and the process flow design, engineering facility planning and seasonal process parameter optimization were completed. The designed treatment capacity of the project is 400 m3/d, which can adapt to the seasonal fluctuation characteristics of the seepage water volume and uranium occurrence form of the mine, with an expected operation cycle of 10 years, and the materials can be recycled after regeneration. The application results show that the process has a significant removal efficiency for radioactive pollutants such as natural uranium, 226Ra, 210Pb and 210Po, the effluent water quality meets the standard stably for a long time, which can provide technical reference and engineering demonstration for the seepage water treatment of similar decommissioned uranium mines in karst areas.
