摘　　要：优化了螯合树脂塔再生废水回收工艺:将酸性废水送至脱氯塔与淡盐水混合,淡盐水脱氯后,被送至盐水工序用于化盐;将碱性废水直接送至盐水工序用于化盐.工艺优化后,实现了酸性废水和碱性废水的高效回收利用.The process for recovery of chelating resin tower regeneration wastewater was optimized.The acid wastewater was sent to the dechlorination tower and mixed with dilute brine.The dilute brine was dechlorinated,then was sent to the brine process for dissolving salt.Alkaline wastewater was directly sent to the brine process for dissolving salt.After process optimization,efficient recovery and utilization of acidic and alkaline wastewater were achieved.
