| 摘 要： | 采用陶瓷膜-二级纳滤-树脂-蒸发集成工艺对含钴高盐废水做处理研究,分析了膜通量随时间衰减变化趋势,确定了树脂吸附优化条件,核算了废水处理成本及收益。结果表明：50 nm陶瓷膜能有效去除水中悬浮颗粒,通量达到933 L/（m 2·h）;纳滤膜能有效实现氯化钴与氯化铵分离,二级平均钴去除率达到71.14%;树脂能深度净化氯化铵溶液,得到的氯化铵产品满足GB/T 2946—2018《氯化铵》。该工艺是一种经济可行的含钴废水处理工艺。

| Abstract: | Cobalt-containing wastewater was treated by ceramic membrane-two stage nanofiltration-resin-evaporation process. The trend of membrane flux changing with time was analyzed.The optimum conditions of resin adsorption was determined and the economic benefits of wastewater treatment process were calculated.The results showed that 50 nm ceramic membrane can effectively remove suspended particles in wastewater,and the flux reached 933 L/(m 2·h).CoCl2 can be separated effectively from NH4Cl by nanofiltration,and the removal rate of Co 2+ reached 71.14%.After deep purification of by resin,NH4Cl met the requirement of GB/T 2946—2018,Ammonium Chloride.The treatment process is an economical and feasible cobalt-contain-ing wastewater treatment process. |
