Wherein the pH value of the acidic electrolyzed oxidizing water (strong acidic electrolyzed water) is 2.0-3.0, and the pH value of the slightly acidic electrolyzed oxidizing water is 5.0-6.5. The water is a quick and efficient disinfectant, and has strong effect of killing microorganisms. The effective components of the acidic electrolyzed water (including slightly acidic electrolyzed water and acidic electrolyzed oxidizing water) comprise effective chlorine and active oxygen, wherein the effective chlorine comprises C1₂、HCIO、CIO^-Etc., and the active oxygen is H₂O₂、O₃And OH, etc. The anode generates other complex electrochemical reactions while generating oxygen evolution and chlorine evolution reactions to generate nascent oxygen which has strong activity and can oxidize O₂And H₂O to form a strongly oxidizing O₃、H₂O₂. Table 1 shows the standard reduction potentials of several electrolytes, in which the standard electrode potential of the active oxygen species is higher and is more difficult to form, and even if it is formed, its amount is relatively small.
