摘　　要：研究了活性炭多维电极法中活性炭荷电特性对腐殖酸去除效果以及在含氨氮的腐殖酸液中pH及电导率对该法去除氨氮的影响 ,指出活性炭荷正电时 ,该法对腐殖酸的去除效果最好 ,而氨氮去除率则随着pH的增加而减少 ,随着电导率的增加而增加。同时分析了本方法去除腐殖酸的作用过程 ,提出了多维电极法去除腐殖酸的作用过程为吸附—分解—脱附的循环过程 ,并且对活性炭具有一定的再生作用 ,可极大地延长活性炭的再生周期 。The effects of the property of granular activated carbon with electron on the removal of humic acids in water by the multi electrodes of granular activated carbon, and the effects of pH and conductivity on the removal of ammonia in water with humic acids were studied. It was shown that a good result of the removal of humic acids can be obtained when the granular activated carbon was charged with positive electron. It was also found that with the increase of conductivity and decrease of pH ,the removal rate of ammionia increases.It can be concluded that this process is the recycling of absorption, decompose and discharge, and this method can expand the life span of granular activated carbon remarkably.
