中文摘要: 采用扩散渗析法对石煤提钒酸浸液进行预处理,考察料液(酸浸液)流速、水料(水/酸浸液)流速比对处理后液pH、硫酸回收率、水反渗率、离子截留率的影响。研究表明,在料液流速12 mL/min、水料流速比1.0~1.1的最佳条件下,预处理后的酸浸液pH由0.04提高到1.0,硫酸回收率为71.12%,水反渗率为14.95%,钒截留率为95.50%。主要杂质离子铝、铁、镁、钾、氟、磷、硫的截留率分别为99.04%、97.37%、98.01%、85.12%、98.33%、91.16%、69.96%。扩散渗析预处理实现了酸浸液pH的提升,同时回收酸可以重新利用。
Abstract:Diffusion dialysis method was applied to pretreat stone coal acid leaching solution. Effects of feed flow rate, flow rate ratio (water/feed) on pH value of dialysate, sulfuric acid recovery, water reverse osmosis rate, and ions rejection were investigated. The results show that the optimum operation conditions include feed flow rate of 12 mL/min and flow rate ratio of water to feed of 1.0~1.1. Under the optimum operation conditions, pH value of acid leaching solution pretreated by diffusion dialysis rises to 1.0 from 0.04, sulfuric acid recovery is 71.12%, water reverse osmosis rate is 14.95%, and vanadium rejection is 95.50%. Rejection of impurity ions, such as Al, Fe, Mg, K, F, P, S is 99.04%, 97.37%, 98.01%, 85.12%, 98.33%, 91.16%, and 69.96% respectively. pH value of acid leaching solution is improved by pretreatment of diffusion dialysis. Recovered acid can be reused.
