果を利用するものである。It has been known to use an aqueous solution of hypochlorite such as sodium hypochlorite for the sterilization of tableware, food or tap water. For example, when sodium hypochlorite (NaClO) is used, the reaction of NaClO with water H 2 O causes hypochlorite (H
ClO) is generated and the bactericidal effect of hypochlorous acid, which has a strong bactericidal power, is utilized.

般に、塩素の殺菌作用は非解離の次亜塩素酸（ＨＣｌ
Ｏ）の状態の殺菌力が最も高く、次亜塩素酸イオンの殺
菌力の８倍とも８０倍ともいわれている。However, in chlorine sterilization using a solution in sodium hypochlorite diluting water, as shown in FIG. 3, the abundance ratio of residual chlorine changes depending on the pH of the aqueous solution. The bactericidal effect varies significantly. Generally, the bactericidal action of chlorine is undissociated hypochlorous acid (HCl
The sterilizing power in the state of O) is the highest, and is said to be 8 times or 80 times the sterilizing power of hypochlorite ion.

するため、殺菌力が弱い。By the way, generally, a commercially available sodium hypochlorite aqueous solution has a strong alkaline pH of about 12,
Residual chlorine concentration required to use as sterilizing water (100
Even if diluted to ~ 200 ppm), the pH can be lowered to about 8 at most. Then, under this pH value, sodium hypochlorite (NaClO) is dissociated into sodium ions Na and hypochlorite ions in water, and is unlikely to be in the form of hypochlorous acid (HClO). That is, as shown in FIG. 3, most of the residual chlorine exists in the form of hypochlorite ion, so that the bactericidal power is weak.

の陽極室で電解することが試みられている。Therefore, p of sodium hypochlorite diluted water is added.
When the H value is lowered to about pH 7 to 3, residual chlorine is hypochlorous acid HC.
In order to exist in the form of 10, it has been attempted to add a chemical such as hydrochloric acid or electrolyze an aqueous solution of sodium hypochlorite in the anode chamber of the diaphragm electrolyzer.

る。However, when the pH is lowered with a chemical such as hydrochloric acid, the cost becomes high, and there is a problem such as corrosion of the piping, and when electrolyzing with a diaphragm, an electrolytic cell is required. , The yield of sterilized water becomes worse than the consumed raw water.

Preferably, sodium hypochlorite is used, and the pH value is lowered to 7 to 3 or pH 3 or less without depending on chemicals or electrolysis, whereby residual chlorine is present in a form having high bactericidal activity. And to provide a device.

を呈する。[Function] By performing an ion exchange treatment on a part or all of the raw water with the hydrogen substitution type exchange material of the ion exchange device, + ions in the water are replaced with hydrogen ions, and the hydrogen ions increase in the water. As a result, the pH value of the raw water itself before adding the hypochlorite aqueous solution falls to 7 to 3 or lower. Even if a sodium hypochlorite aqueous solution having a pH of about 12 is added to this raw water, the mixing ratio of the raw water and the sodium hypochlorite aqueous solution is about 250: 1. The pH value remains almost unchanged and is maintained at pH 7-3 or below. Therefore, residual chlorine in the water to which sodium hypochlorite is added and mixed is present in the form of hypochlorous acid (HClO) and exhibits a strong bactericidal action.

害がなくなる。When the water after the sodium hypochlorite is added and mixed with the raw water is subjected to the ion exchange treatment with the hydrogen substitution type ion exchange material, the pH value of the mixed water becomes 7 to 3 or 3 or less by the same action. The residual chlorine becomes strong sterilizing water existing in the form of HClO hypochlorous acid. Further, since sodium is reduced by replacing sodium ions with hydrogen ions, salt damage is eliminated.
