In response to the high hardness of discharged water (350~900 mg/L CaCO₃), seasonal water scarcity, and pipeline scaling risk at Wushan Copper Mine in Jiangxi, this study developed a softening and reuse process based on ion exchange resin. Laboratory-scale tests were conducted to select a domestic Zhengguang (working exchange capacity 550~600 mmol/L). Operating parameters were optimized (flow rate 12 m/h, regenerant concentration 6%~8% NaCl), and the feasibility was verified at an industrial scale of 120 m³/h. Results showed that the softened water hardness was stably controlled at 0~130 mg/L CaCO₃, with a Ryznar stability index of 6.0~7.3. Regenerant salt consumption was 210~245 g/mol, and treatment cost per ton of water was 0.686 RMB/ton, of which the salt cost was 0.684 RMB/ton. Resin cost per cubic meter of softened water was 0.069 RMB/m³, and the average electricity cost for recycled water was 0.002 RMB/m³, comparable to current water intake cost. Concentrations of heavy metals in the regeneration waste complied with the GB 25467—2010 discharge standards (Pb<0.37 mg/L, Zn<0.45 mg/L). This technology addressed the production risk caused by seasonal water interruptions of the Nanyang River, achieved 100% wastewater reuse, and provided a solution for treating high-hardness mine wastewater.

针对江西铜业股份有限公司武山铜矿外排水硬度高（350~900 mg/L，CaCO₃）、季节性水源短缺及管道结垢风险问题，通过实验室小试筛选出国产争光树脂（工作交换容量550~600 mmol/L），优化运行参数（流速12 m/h，再生液浓度6%~8% NaCl），并在120 m³/h工业规模验证其可行性。结果表明：软化水硬度稳定控制在0~130 mg/L （以CaCO₃计），Ryznar稳定指数（RSI）6.0~7.3，再生盐耗210~245 g/mol。成本与现有取水方式相当，吨水处理成本为0.755元，其中：盐0.684元，树脂0.069元，电0.002元。再生废液中重金属浓度符合《GB 25467—2010》排放标准（Pb<0.37 mg/L，Zn<0.45 mg/L）。该技术可实现废水回用率100%，解决了南阳河季节性断流影响生产的问题，为高硬度矿山废水处理提供了解决方案。
