摘要
本文对常规阴离子交换树脂法中的再生剂做了一些研究和改进 ,将常规处理后的强碱型阴离子交换树脂再处理成重碳酸盐型树脂 ,然后用于交换 ,并选用 (MgO +CO2 )为再生剂 ,从而大大提高了再生效率。根据一系列实验结果得出了最佳再生剂的浓度、该树脂对NO-3 -N的穿透容量、NO-3
In this paper improvement of the regenerant of ordinary anion exchange resin was introduced. The strong base type anion exchange resin was treated and transfered to the bicarbonate type. By choosing (MgO+CO 2)as regenerant, the regeneration efficiency was greatly increased. According to the experimental results, the optimum concentration of regenerant, the B.T.C?NO - 3 removal efficiency and water output were obtained.
