tract:Experiments of water treatment for killing mocrobe and removing iron to improve the quality of the water in water tanks were conducted using a strong oxidizing agent produced during electrolysis of water by a self-develped electrode.The results showed that by once - through treatment of water flow,bacteria killing rate was > 99% with electrical power consumption ≤ 0.1 kWh/m3,and iron removal rate was > 99% with electrical power consumption ≤ 0.08 kWh/m3.The algae removal effect was examined by measuring the dissolved oxygen content in the water.With cyclic treatment of water in water tanks,the total iron content in the water dropped from 14 mg/L to ≤ 0.3mg/L,and the total number of bacteria from 104 cfu/mL to ≤30 cfu/mL.When the treated water was used in flushing urinal,urinous scale was eliminated.
