【Abstract】 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.更多还原
