Abstract:

The influential factors of direct current elect rolysis disinfection are studied.The higher density of the direct current,the better the ef fect of disinfection. When the water flow amount is 1m³/ h and the direct current density is 7. 5 mA/ cm², the lower pH value of water sample, the better the effect of disinfection;The higher concent ration of ammonia, the worse the effect of disinfection;And the higher concent ration of chloride,the better the effect of disinfection. When elect rolysis disinfection is applied in purifying water,the disinfection effect is pretty good,and the disinfected water is approved with the Drinking Water Sanitation Standard( CJ94 1999), with continuous sterilization effect.The direct current electrolysis appliance can be used in drinking water disinfection.

Key words: disinfection of purified drinking water, direct current elect rolysis, continuous disinfection effect

摘要：

主要研究直流电解杀菌的影响因素及其应用于饮用净水的消毒。电流密度越大,杀菌效果越好。在额定水流量 1m³ /h,选定电流密度 7.5mA/cm² 的情况下,水样的pH值低,杀菌效果好,水中的氨氮含量越高,杀菌效果越差,水中的氯离子浓度越高,杀菌效果越好。在电解杀菌应用于饮用净水的消毒中,杀菌效果十分显著,出水符合饮用净水卫生标准 (CJ94— 1999),且具有持续杀菌作用,可作为一种消毒装置应用于饮用净水的消毒。
