摘要为了对含汞废水的电吸附处理条件进行研究，首先要对除汞方法进行一定了解。本文研究了ACF以及Ni-ACF电吸附脱汞实验，主要结果如下：
（1）ACF的最佳脱汞条件为汞离子的初始浓度为1000μg/L，电压为2V，电解质浓度为0。018g/ml条件下活性炭纤维电吸附除汞离子的效果最好。
（2）活性炭纤维的最佳改性负载量为5g。88950
（3）Ni-ACF的最佳脱汞条件为汞离子的初始浓度为1000μg/L，电压为1V，电解质浓度为0。018g/ml条件下活性炭纤维电吸附除汞离子的效果最好。
（4）在最佳条件下，Ni-ACF电吸附与ACF电吸附脱汞性能相比有了很大提高，吸附量能够从改性前的469。35μg提高到484。95μg。
所以在工业处理含汞废水中，可以通过活性炭纤维来处理含汞废水，并且改变活性炭纤维的性质，来进一步提高对汞离子的去除效率。

Abstract In order to electric adsorption condition for the research of mercury containing waste water, first of all to the mercury ion concentration in the wastewater was determined, and on mercury removal method must understand。 This paper studies the ACF and Ni-ACF electric adsorption mercury removal experiments, the main results are as follows:
(1) The best mercury removal condition of ACF is the initial concentration of mercury ion is 1000 ug/L, the voltage is 2V, the electrolyte concentration is 0。018g/ml, the adsorption effect of activated carbon fiber is best
(2) The optimum condition of activated carbon fiber is 5g。
(3) The best mercury removal condition of Ni-ACF is the initial concentration of mercury ion is 1000 ug/L, the voltage is 1V, the electrolyte concentration is 0。018g/ml, the adsorption effect of activated carbon fiber is best
(4)Under the optimum conditions, the mercury removal performance of Ni-ACF and ACF was greatly improved, and the adsorption capacity was increased from 469。35 ug to about 484。95 ug。
Therefore, in the industrial treatment of mercury containing waste water, activated carbon fiber can be used to deal with mercury containing wastewater, and change the properties of activated carbon fibers, to further improve the removal efficiency of mercury ions。
