采用颗粒活性炭、粉末活性炭和活性炭负载壳聚糖对高锰地下水进行静态吸附试验，利用颗粒活性炭进行动态吸附试验，研究了静态条件下吸附剂投加量、pH值、温度对吸附效果的影响，以及动态条件下浓度和流速对吸附效果的影响。结果表明，三种吸附剂吸附效果相差不大，相对而言粉末活性炭效果最好，颗粒活性炭效果与粉末活性炭较接近；静态试验中，当水中Mn2+的浓度为5mg/L时，水温25oC、pH值为6.8～7.0状态下颗粒活性炭的处理效果最好，最佳投加量为0.02g/L，即0.4g（GAC）/mg(Mn2+)；动态条件下，锰离子浓度增加和水流流速增大都会使初始穿透点提前。

The granular activated carbon, powdered activated carbon, and activated carbon-loaded chitosan were used in the static adsorption experiment of high Mn groundwater, and the granular activated carbon was used in the dynamic adsorption experiment of high Mn groundwater, which can determine the effects of adsorbent dosage, pH value, and temperature on the adsorption efficacy under the static conditions and the effects of Mn2+ concentration and flow velocity on the adsorption efficacy under the dynamic conditions. The results showed that the adsorption efficacy is similar for the three adsorbents with the powered activated carbon having a relatively better adsorption efficacy. Under the static conditions with the Mn2+ concentration of 5 mg/L, temperature of 25 o C, and pH value of 6.8~7.0, the granular activated carbon had the best adsorption efficacy and the best dosage was 0.02 g/L, i.e. 0.4g ( GAC ) /mg ( Mn2+ ). Under the dynamic conditions，the increasing of Mn2+ concentration and flow velocity can advance the initial penetration point．
