摘　　要：本文以活性炭多维电极法 ,去除水中氯消毒副产物的前驱物 -溶解态腐殖酸。文章比较了活性炭多维电极法与活性炭单纯吸附的去除效果 ,讨论了水样 p H值、Ca2 +浓度、外电压。A new way, multi-electrodes of granular activated carbon(MEGAC), was used to remove the dissolved humic acids (HAs), the main precursors of disinfection by-products in chlorination in drinking water. The removal results were compared in the processes of MEGAC and adsorption by granular activated carbon (GAC). The effect of pH value, Ca 2+ concentration, voltage, the dimension and quantity of GAC on the removal results of HAs was investigated.
