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 。
The influential factors of direct current electrolysis disinfection are studied. The higher density of the direct current, the better the effect of disinfection. When the water flow amount is 1 m 3/h and the direct current density is 7.5 mA/cm 2, the lower pH value of water sample, the better the effect of disinfection; The higher concentration of ammonia, the worse the effect of disinfection; And the higher concentration of chloride, the better the effect of disinfection. When electrolysis 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.
