以天津市政地表源水为研究对象，考察了磁性离子交换树脂(MIEX)对市政地表源水中有机物的去除规律。确定了不同季节天津市政源水的 MIEX 工艺操作条件。实验结果表明：与常规混凝工艺相比 MIEX 与混凝联用处理不同季节天津市政源水，UV254和CODMn去除率分别提高40%,和19%,以上。同时对MIEX树脂吸附机理进行研究，结果证明 MIEX 树脂具有良好的脱附再生性能，Freundlich 模型和准二级动力学方程能比较好地描述吸附过程，吸附过程放热，低温有利于吸附进行。

In this research,Tianjin’s municipal raw water was treated with magnetic ion exchange resin(MIEX). The re-moval rate of organism and optimum technology conditions were examined in different seasons. It showed that the removal rates of UV254 and CODMn were enhanced by 40%, and 19%respectively, by MIEX resin combined with coagulation. The study of absorption mechanism showed that the MIEX resin had good properties of desorption and regeneration. The Freundlich model and the pseudo-second-order model could express the absorption process. The absorption reaction was exothermic,and low temperature was beneficial to adsorption.
