摘　　要：以饮用水中细菌总数和大肠杆菌群为指标，以石墨板和钛板为电极，对电化学消毒过程中的主要影响因素进行了研究。发现在处理时间相同时，杀菌率随电流密度的增大而增大、随水样ｐＨ的降低而增大，杀菌率（α）与处理时间（ｔ）之间的关系为：α＝Ｋ１ｅ－Ｋ２／ｔ。并对能量的消耗和杀菌机理进行了讨论。The electrochemical disinfection process for drinking water treatment was studied with total count of bacteria and the coliform count as water quality indexes, using graphite plates and titanium plates as the electrodes, It was forund that the bactericidal officiency increased as the direct current density increased and the pH value decreased. The relationship between the bactericidal effciency and the treatment time was given. The power consumption and reaction mechanisms of the process were discussed.
