Description

  The present invention relates to water used for cleaning, disinfection (sterilization), or wound healing.

  Recently, it has been proposed to use anodic electrolyzed water obtained by electrolyzing a saline solution, particularly for disinfection (sterilization). When used for such purposes, the anode electrolyzed water is said to have an oxidation-reduction potential (ORP) of about 1100 mV or more.

Anode electrolyzed water having such characteristics can be obtained using an electrolyzer (two-chamber electrolyzer) as shown in FIGS.
In FIG. 15, 51 is an anode chamber and 52 is a cathode chamber. The anode chamber 51 and the cathode chamber 52 are partitioned by a diaphragm (cation exchange membrane) 53. 54 is an anode electrode, and 55 is a cathode electrode.
And salt solution is supplied from inlet 51a, 52a, and electrolysis is performed. Then, anode electrolyzed water is obtained from the outlet 51 b of the anode chamber 51, and cathode electrolyzed water is obtained from the outlet 52 b of the cathode chamber 52.

By the way, the reaction occurring in the anode chamber 51 is as follows.
(1) 2Cl ⁻ −2e ⁻ → Cl ₂
(2) 2H ₂ O −4e ⁻ → O ₂ + 4H ⁺
(3) Cl ₂ + H ₂ O → HClO + HCl
The reaction occurring in the cathode chamber 52 is as follows.
(4) 2H ₂ O + 2e ⁻ → H ₂ + 2OH ⁻
FIG. 16 shows the above reaction as a diagram.

  Then, as understood from the above reaction formula and FIG. 16, chlorine ions move to the anodic chamber 51. At the same time, sodium ions migrate to the cathode chamber 52. Therefore, anodic electrolyzed water always shows acidity by chlorine ions. Cathodic electrolyzed water always exhibits alkalinity due to sodium ions.

  By the way, when the anode electrolyzed water produced in the presence of chlorine ions is used as the disinfecting (sterilizing) water, it is said that the higher the ORP of the anode electrolyzing water, the better the disinfecting (sterilizing) effect. In order to increase the ORP of the anode electrolyzed water, it is necessary to increase the electrolysis current. As the electrolysis current increases, the amount of movement of chlorine ions and sodium ions also increases. As a result, the amount of chlorine ions in the anode chamber increases. And the pH value of anode electrolysis water becomes small. That is, the anode electrolyzed water has a strong acidity.

However, acidic water having a small pH value has a strong corrosive force. For example, acidic water having a pH of 3 or less easily corrodes metals.
Therefore, in order not to cause corrosion, it is preferable that the pH of the disinfecting (sterilizing) water is close to 7.
Furthermore, when anodic electrolyzed water is used for disinfection (sterilization) of the human body, for example, when anodic electrolyzed water is used for cleaning / disinfection (sterilization) of doctors, nurses or patients after surgery, anode electrolysis is used. The pH of water is preferably close to that of human blood or body fluid.

However, when an anode electrolyzed water having an ORP of about 1100 mV or more is obtained using the conventional two-chamber electrolyzer shown in FIG. 15, the pH of the anode electrolyzed water is 3 or less. That is, the anode electrolyzed water by the two-chamber electrolyzer has a strong acidity.
Therefore, it is not preferable to use such anode electrolyzed water as disinfecting (sterilizing) water.

By the way, as the electrolysis apparatus, not the two-chamber electrolysis apparatus as shown in FIG. 15 but a three-chamber electrolysis apparatus proposed by the present inventors is also known. The outline of this three-chamber electrolyzer is shown in FIGS.
FIG. 1 is a schematic view showing a main part of the electrolysis apparatus. FIG. 2 is a plan view of the electrode plate. FIG. 3 is a schematic view showing the entire apparatus.

1 is an anode chamber and 2 is a cathode chamber. Reference numeral 3 denotes an intermediate chamber provided between the anode chamber 1 and the cathode chamber 2. The anode chamber 1 and the intermediate chamber 3 are partitioned by a diaphragm 4. The cathode chamber 2 and the intermediate chamber 3 are partitioned by a diaphragm 5. 6 and 7 are electrode plates in which a large number of holes are formed, as can be seen from FIG. The electrode plates 6 and 7 are laminated in close contact with the diaphragms 4 and 5. However, since the electrode plate 6 is an anode electrode, the electrode plate 6 is provided so as to face the anode chamber 1. Since the electrode plate 7 is a cathode electrode, the electrode plate 7 is provided so as to face the cathode chamber 2. The intermediate chamber 3 is filled with glass beads or ion exchange resin. In addition, when the water supplied to the intermediate chamber 3 contains an electrolyte substance (MX (X is Cl, for example)), conductivity is ensured. Therefore, the intermediate chamber 3 may not be filled with the ion exchange resin. However, in such a case, glass beads are filled.
1a is an anode chamber inlet and 1b is an anode chamber outlet. 2a is a cathode chamber inlet, and 2b is a cathode chamber outlet. 3a is an intermediate chamber inlet and 3b is an intermediate chamber outlet.
Reference numeral 8 denotes a pipe connected to the anode chamber inlet 1a and the cathode chamber inlet 2a. Water is supplied through this pipe 8. Reference numeral 9 denotes a circulation pipe connected to the intermediate chamber inlet 3a and the intermediate chamber outlet 3b. An intermediate chamber water (for example, water to which an electrolyte substance such as saline is added) tank 10 is provided in the middle of the circulation pipe 9. Then, the saline solution in the tank 10 is supplied to the intermediate chamber 3 by the force of the pump 11. Reference numeral 12 denotes a water storage tank. The tank 12 and the anode chamber outlet 1b are connected by a pipe 13. Therefore, the anode electrolyzed water is stored in the tank 12.

  When such a three-chamber electrolysis apparatus is used, the saline solution is not directly supplied to the anode chamber 1 and the cathode chamber 2. Therefore, the chlorine ion concentration in the anode electrolyzed water is expected to be low.

  However, it is inevitable that chlorine ions move from the intermediate chamber 3 to the anode chamber 1. Accordingly, the anode electrolyzed water becomes acidic.

  Therefore, the problem to be solved by the present invention is that although the disinfection (sterilization) ability or wound healing ability is high, the pH of the liquid is close to 7, that is, a weakly acidic region, a neutral region, or It is to provide water in a weak alkaline region.

  That is, the pH is close to 7, that is, a weakly acidic region, a neutral region, or a weakly alkaline region, which has low adverse effects on the human body, but provides water with high disinfection (sterilization) ability or wound healing ability. That is.

  By the way, the reaction that occurs during electrolysis is different between the case where the three-chamber electrolysis apparatus shown in FIG. 1 is used and the case where the two-chamber electrolysis apparatus shown in FIG. 15 is used.

(A) Cathodic electrolyzed water by a three-chamber electrolyzer is not just water in which OH ⁻ and H ₂ gas produced according to the above equation (4) are dissolved. That is, various reducing substances are dissolved according to the following reaction formula.
(5) O ₂ + e ⁻ → O ₂ ⁻
(6) HO ₂ ⁻ + H ₂ O + e ⁻ → 2OH · + OH ⁻
(7) O ₂ + H ⁺ + E ^- → HO ₂
(8) 2O ₂ + 2H ₂ + 2e ⁻ → H ₂ O ₂ + 2OH ⁻
(9) O ₂ + H ₂ O + 2e ⁻ → HO ₂ ⁻ + OH ⁻
The generated oxygen reducing substance is a kind of active oxygen. Therefore, these substances are expected to have antibacterial activity.

On the other hand, the cathode electrolyzed water is alkaline.
Therefore, when the pH is adjusted by adding the cathode electrolyzed water to the anode electrolyzed water, the cathode electrolyzed water is closer to the neutral region than the acid value of the anode electrolyzed water itself. That is, when anode electrolyzed water and cathode electrolyzed water are mixed, it is easy to adjust the pH of this mixed water to 6-8.

  Moreover, since the cathode electrolyzed water itself used for neutralization contains many active species, the addition of the cathode electrolyzed water acts to increase the ORP. Therefore, the disinfection (sterilization) effect is enhanced. This is completely different from the case where the anode electrolyzed water is neutralized using an alkali such as caustic soda.

  In addition, the production | generation efficiency of the active species produced | generated by the said reaction formula is dependent on the structure of an electrolytic cell. That is, when a three-chamber electrolysis device is used, the dissolved oxygen concentration in the intermediate chamber 3 is increased by the diffusion of the oxidizing substance from the anode electrode 6. This dissolved oxygen passes through the diaphragm 5 and is supplied to the surface of the cathode electrode 7. Therefore, the production efficiency of active species is increased. On the other hand, when a two-chamber electrolysis apparatus is used, the phenomenon as described above hardly occurs. For this reason, the present invention cannot be considered.

(B) By the way, when chlorine ions, which are one of halogen ions, are supplied to the intermediate chamber 3 of the three-chamber electrolysis apparatus, the residual chlorine concentration in the anodic electrolyzed water is determined by the water supply speed to the anodic chamber 1. I have come to know that it depends. That is, FIG. 4 shows the relationship between the residual chlorine concentration in the anodic electrolyzed water and the water supply rate to the anodic chamber 1 when a three-chamber electrolyzer is used. According to this, the smaller the flow rate, that is, the lower the supply rate of water to the anode chamber 1, the higher the residual chlorine concentration.
However, considering the efficiency, a higher flow rate is better.

  Therefore, in order to increase the production efficiency while increasing the residual chlorine concentration, a water bypass line is provided in the electrolytic cell, and the flow rate of water in the electrolytic cell (anode chamber) is lowered and water is allowed to flow through the bypass line. Can be considered. This makes it possible to increase the residual chlorine concentration while ensuring the water flow rate.

(C) By covering the surface of the anode electrode 6 (the surface on the water flow side) with a nonwoven fabric, gas components such as oxygen generated by electrolysis are likely to stay. That is, the following reaction occurs on the surface of the anode electrode 6 and oxygen gas is easily generated.
      (10) 2H₂O-4e⁻            → O₂+ 4H⁺
      (11) H₂O + O₂  -2e⁻   → 2H⁺+ O₃
      (12) 2H₂O-2e⁻            → 2O ・ + 4H⁺
      (13) 2H₂O-3e⁻            → 3H⁺+ HO₂
      (14) 2H₂O-2e⁻            → 2H⁺+ H₂O₂
  In other words, O₃Oxidizing substances such as O and O are easily generated. Then, these substances react with chlorine ions transferred from the intermediate chamber, for example, (O₃-Cl⁻) Is produced. These intermediates are finally converted to HClO and the like. Therefore, Cl₂HClO is produced without going through.

In addition, since the oxygen gas stays around the anode electrode, the current density increases as a result. In addition to the above reaction, the generation efficiency of active oxygen species such as HO ₂ and H ₂ O ₂ is improved.

By the way, in order to produce higher ORP water, it is preferable to improve the production efficiency of stronger oxidizing substances such as O ₃ . Therefore, it is preferable that the reaction represented by the formula (11) occurs. For this purpose, oxygen gas is preferably retained on the surface of the anode electrode 6.
Therefore, it is preferable to cover the surface of the anode electrode 6 (surface on the water flow side) with a nonwoven fabric.

(D) The solubility of O ₂ gas and Cl ₂ gas generated in the anode chamber 1 and further intermediates such as (O ₃ —Cl ⁻ ) in water is more neutral or alkaline than water in the acidic region. The area is higher. Therefore, when the anode electrolyzed water and cathode electrolyzed water generated by electrolysis are mixed as soon as possible, the active species are less likely to evaporate into the air. And the density | concentration of an active species increases. In addition, the lifetime of the active species is extended. Mixing is performed, for example, within 300 minutes after the generation of electrolyzed water. More preferably, it is performed within 30 minutes. Of course, it is most preferably performed immediately after. Therefore, the anode chamber outlet 1b and the cathode chamber outlet 2b and the water storage tank 12 are connected by a pipe, and the anode electrolyzed water and the cathode electrolyzed water are mixed as soon as possible.

That is, the anode electrolyzed water and the cathode electrolyzed water are stored separately, and are not mixed for cleaning and disinfection (sterilization).
The above idea was confirmed by the following experiment.

  First, electrolysis was performed using the three-chamber electrolysis apparatus shown in FIGS.

  Pure water was supplied to the anode chamber 1 from the anode chamber inlet 1a at a rate of 1.0 L / min. Pure water was also supplied to the cathode chamber 2 from the cathode chamber inlet 2a at a rate of 1.0 L / min. Saturated saline was supplied to the intermediate chamber 3 from the intermediate chamber inlet 3a at a rate of 2.5 L / min. The electrode plates 6 and 7 are made of platinum-plated titanium. The size is 80 cm × 60 cm. The diaphragm 4 is a laminate of a fluorine-based cation exchange membrane (Nafion 117 manufactured by DuPont) and an anion exchange membrane (AMV manufactured by Asahi Glass Co., Ltd.). The diaphragm 5 is a fluorine-based cation exchange membrane (Dupont Nafion 424). The intermediate chamber 3 was filled with glass beads having a diameter of 2 mm.

For comparison, electrolysis was performed using the two-chamber electrolysis apparatus shown in FIG.
The materials and sizes of the electrodes 54 and 55 are the same as those of the electrode plates 6 and 7. The diaphragm 53 is an AMV manufactured by Asahi Glass Co., Ltd. A saline solution having a concentration of 0.05 wt% was supplied to the anode chamber 51 and the cathode chamber 52 at a rate of 1.0 L / min.
In both cases, the electrolysis current is 12A.

And cathode electrolyzed water was extract | collected and the active oxygen concentration was measured, The result is shown in Table-1. Luminol reaction was used as a measurement method. Incidentally, _{O 2} by luminol reaction ^- or _O ^{2 2-or} the like can be measured. Moreover, since oxidation-reduction potential (ORP) was measured, the result is shown in Table-1. The sample electrode is platinum. Moreover, since the pH of cathode electrolysis water was measured, the result is shown in Table-1.
Table-1
Fluorescence intensity (relative value) ORP (mV) pH
Three-chamber electrolysis device 15 20 11.9
Two-chamber electrolyzer 1-890 12

  As can be seen from Table 1, the cathode electrolyzed water in the case of using the three-chamber electrolyzer has higher generation efficiency of active oxygen. And although pH is substantially the same, ORP is much higher in the cathode electrolyzed water of the three-chamber electrolyzer. Generally, since the alkaline reducing water contains hydrogen gas, the ORP is lowered to −800 mV or less. However, the fact that the ORP of the cathode electrolyzed water obtained using the three-chamber electrolyzer is 20 mV indicates that active oxygen contributes to the potential rather than hydrogen gas.

Next, the result of the relationship between the residual chlorine concentration and the flow rate of the anode chamber will be described.
The relationship between the residual chlorine concentration in the anodic electrolyzed water and the supply rate of water to the anodic chamber 1 when using a three-chamber electrolyzer is as shown in FIG. As is clear from FIG. 4, the relationship between the residual chlorine concentration and the flow rate is not a linear relationship. That is, the smaller the flow rate, the higher the residual chlorine concentration per unit flow rate. For example, when the flow rate is 1.0 L / min, the residual chlorine concentration is 25 ppm, but when the flow rate is 0.5 L / min, the residual chlorine concentration is 70 ppm. When the flow rate is 0.5 L / min and converted to 1.0 L / min, the residual chlorine concentration is 35 ppm. By suppressing the flow rate in this way, the generation efficiency of active species is improved.

  Therefore, when the bypass line 14 as shown in FIG. 5 is provided, it can be expected that the generation efficiency of the active species is improved. The bypass line 14 is provided in parallel with the anode chamber 1. That is, one end side of the bypass line 14 is connected to the pipe 8, and the other end side of the bypass line 14 is connected to the pipe 13. Accordingly, part of the water that has passed through the pipe 8 is sent to the anode chamber 1. The remaining water passes through the bypass line 14 and merges with the anode electrolyzed water through the pipe 13. In FIG. 5, the same reference numerals as those in FIGS. 1 to 3 denote the same components.

And when electrolysis was performed by the apparatus of FIG. 5, since the residual chlorine concentration, pH, and ORP of the water stored in the water storage tank 12 were investigated, the result is shown in Table-2. In addition, the water (flow rate 1L / min) sent via the pipe 8 is reverse osmosis membrane treated water.
Table-2
Anode chamber flow rate Bypass line flow rate Residual chlorine concentration ORP (mV) pH
0.1 L / min 0.9 L / min 100 ppm 1120 3.6
0.2 L / min 0.8 L / min 90 ppm 1130 3.3
0.5 L / min 0.5 L / min 70 ppm 1150 3.1
0.7 L / min 0.3 L / min 30 ppm 1160 2.9
1.0 L / min 0.0 L / min 25 ppm 1170 2.8

  From Table 2, it can be seen that by increasing the amount of water passing through the bypass line and reducing the amount of water supplied to the anode chamber, the concentration of residual chlorine (active species) increases and the electrolysis efficiency improves. Moreover, the pH value becomes high. That is, the acidity of the water in the water storage tank 12 is weak.

Next, in the apparatus of FIG. 5, the surface of the anode electrode 6 was covered with a non-woven fabric made of Teflon. Then, reverse osmosis membrane treated water was supplied to the anode chamber 1 at a rate of 0.2 L / min. Further, water was supplied to the bypass line 14 at a rate of 1.8 L / min. Accordingly, anode electrolyzed water is generated at a rate of 2 L / min as a whole.
For comparison, the same process was performed when the surface of the anode electrode 6 was not covered with a non-woven fabric made of Teflon.

And since the ORP and pH of the anode electrolyzed water collected in the water storage tank 12 were measured, the result is shown in Table-3.
Table-3
ORP (mV) pH
Use non-woven fabric 1142 3.5
Non-woven fabric is used 1130 3.3

As can be seen from Table-3, the anode electrolyzed water has a higher pH when the anode electrode is covered with the nonwoven fabric. The ORP is also high.
Therefore, it is preferable to cover the anode electrode with a nonwoven fabric.

  High disinfection (sterilization) ability. In addition, the wound healing ability is high.

  However, the pH of the liquid is close to 7. For example, it is in a weak acid region, a neutral region, or a weak alkali region. Therefore, when this water is used for disinfection and sterilization of the human body, since the acidity is lower than that of the conventional anode electrolyzed water, side effects on the human body are small.

Despite its high ability to disinfect (disinfect) and wound healing, it has a lower acidity than conventional anode electrolyzed water, for example, in a weakly acidic region, neutral region, or weakly alkaline region ,
An anode electrolyzed water obtained by electrolytic treatment using an electrolyzer comprising an anode chamber, a cathode chamber, and an intermediate chamber provided between the anode chamber and the cathode chamber;
A mixed water with an anode chamber, a cathode chamber, and canode electrolyzed water obtained by electrolytic treatment using an electrolysis apparatus including an intermediate chamber provided between the anode chamber and the cathode chamber is used.

[Example 1]
The three-chamber type electrolytic cell shown in FIG. 1 (including the anode chamber 1, the cathode chamber 2, and the intermediate chamber 3 provided between the anode chamber 1 and the cathode chamber 2) was used. This three-chamber electrolytic cell itself is known.

  An apparatus incorporating this three-chamber electrolytic cell as shown in FIG. 6 was developed. The apparatus shown in FIG. 6 is different from the apparatus shown in FIG. 3 only in that the pipe 15 connected to the cathode chamber outlet 2b is connected to the pipe 13 in this embodiment.

  That is, the first embodiment is characterized in that part of the cathode electrolyzed water is guided to the water storage tank 12. That is, in the water storage tank 12, mixed water of anode electrolyzed water and cathode electrolyzed water can be obtained although the mixing ratio varies depending on the opening degree of the valve 16 provided at the branch point. The opening degree of the valve 16 is adjusted by the output signal of the pH sensor 17 provided in the water storage tank 12, and the mixing ratio is adjusted. The mixing of the anode electrolyzed water and the cathode electrolyzed water was performed within 3 minutes after the electrolyzed water was generated.

  Then, saturated saline was supplied to the intermediate chamber 3. Moreover, pure water was supplied to the anode chamber 1 at a rate of 0.5 L / min. Moreover, pure water was supplied to the cathode chamber 2 at a rate of 0.025 L / min. And it electrolyzed on the conditions of the electrolysis current 11A. The intermediate chamber 3 is filled with glass beads. And the ion exchange resin is not filled.

  In this way, mixed water having a pH of 4 to 8 was obtained.

And since the disinfection and disinfection effect of this mixed water was investigated, the result is shown in Table-4. That is, 1 ml of an aqueous solution containing 10 ⁶ E. coli / ml and 10 ml of mixed water were mixed and stirred for 1 minute. Thereafter, the mixture was smeared on an agar medium and cultured at 25 ° C. for 24 hours. At this time, the case where E. coli was not recognized was indicated by “0”. The case where the number of E. coli was 1 to 10 was indicated by “1”. The case where the number of E. coli is 11 to 100 is indicated by “2”. The case where the number of E. coli was 101 to 1000 was indicated by “3”. The case where the number of E. coli is 1001 or more is indicated by “4”.

It also shows the pH, ORP, and residual chlorine concentration of the mixed water. The KI colorimetric method was used for measuring the residual chlorine concentration. Therefore, this measurement includes not only chlorine but also other oxidizing substances. However, since active oxygen such as O ₂ ⁻ does not cause a color reaction, the active species are not included in the residual chlorine concentration.

  Furthermore, the disinfection / sterilization effect, pH, ORP, and residual chlorine concentration are shown for only the anode electrolyzed water and only the cathode electrolyzed water.

Table-4
pH ORP Chlorine concentration Disinfecting / sterilizing effect mixed water 4 1030 mV 60 ppm 0
5 970 mV 60 ppm 0
6 910 mV 50 ppm 0
7 850 mV 50 ppm 0
8 790 mV 40 ppm 0
Anode electrolyzed water 2.5 1170 mV 65 ppm 0
Cathode electrolyzed water 12.4 -234 mV 0 1

  From Table 4, it can be seen that the mixed water of the anode electrolyzed water and the cathode electrolyzed water according to the present invention is excellent in disinfecting / sterilizing effect even when the pH value is increased.

  If compared with anode electrolyzed water having a pH of 2.5, the mixed water of the present invention (anode electrolyzed water + cathode electrolyzed water) is weakly acidic or weakly alkaline. Accordingly, it is understood that there is little adverse effect on the human body. That is, it can be understood that it is preferable as disinfecting / sterilizing water.

  In addition, compared with anode electrolyzed water or the mixed water of the present invention, cathode electrolyzed water has poor disinfection and sterilization effects.

[Example 2]
In Example 1, pure water was supplied to the intermediate chamber 3 instead of supplying saturated saline. However, when pure water is supplied, the electrolysis voltage must be 1000 V or higher. Therefore, in order to lower the electrolysis voltage, the intermediate chamber 3 was filled with an ion exchange resin (Nafion NR50 (fluorine cation exchange resin) manufactured by DuPont), so that the electrolysis voltage is 20 V. The electrolysis current is 10 A. In addition, as an ion exchange resin, both an anion exchange resin or both a cation exchange resin and an anion exchange resin can also be used.
And the mixed water whose pH is 6-8 was obtained.

Since the disinfection / sterilization effect, pH, ORP, and residual chlorine concentration of this mixed water were examined in the same manner as in Example 1, the results are shown in Table-5.
Table-5
pH ORP Chlorine concentration Disinfecting / sterilizing effect mixed water 6 750 mV 2 ppm 1
7 650 mV 2 ppm 1
8 500mV 2ppm 2
Anode electrolyzed water 5.8 850 mV 3 ppm 2
Cathodic electrolyzed water 8.9 -110 mV 0 2

  Also in the present embodiment, the mixed water of the anode electrolyzed water and the cathode electrolyzed water according to the present invention has a disinfecting / sterilizing effect like the anode electrolyzed water. And the pH value of mixed water is high.

In the present embodiment, an aqueous solution of an electrolyte substance having chlorine ions is not supplied to the intermediate chamber 3. Therefore, as can be seen from the comparison with Table 4, the concentration of chlorine contained in the anode electrolyzed water and the cathode electrolyzed water is low. For this reason, the disinfection / sterilization effect is weaker than that of Example 1.
Therefore, it is preferable to use electrolyzed water (anode electrolyzed water + cathode electrolyzed water) that is performed by supplying an electrolyte substance having chlorine ions to the intermediate chamber 3.

[Example 3]
In Example 1, the surface of the anode electrode 6 was covered with a non-woven fabric made of Teflon, and the same operation was performed.
And the mixed water whose pH is 4-8 was obtained.

Since the disinfection / sterilization effect, pH, ORP, and residual chlorine concentration of this mixed water were examined in the same manner as in Example 1, the results are shown in Table-6.
Table-6
pH ORP Chlorine concentration Disinfecting / sterilizing effect mixed water 4 1045 mV 75 ppm 0
5 985 mV 70 ppm 0
6 925 mV 70 ppm 0
7 865 mV 70 ppm 0
8 805 mV 65 ppm 0
Anode electrolyzed water 2.8 1165 mV 80 ppm 0
Cathode electrolyzed water 12.4 -235 mV 0 1

In contrast to Example 1, the ORP of the mixed water of Example 3 is high. Therefore, compared with the mixed water of Example 1, it can be expected that the mixed water of Example 3 will have a higher disinfection / sterilization effect.
Therefore, electrolyzed water obtained by using an electrolyzer in which the surface of the anode electrode 6 is covered with a nonwoven fabric is preferred.

[Example 4]
In Example 1 (FIG. 6), the bypass line 14 as shown in FIG. 5 was provided. That is, an apparatus incorporating a three-chamber electrolytic cell as shown in FIG. 7 was produced.
And it carried out similarly to Example 1 and obtained mixed water with pH 4-8.

Since the disinfection / sterilization effect, pH, ORP, and residual chlorine concentration of this mixed water were examined in the same manner as in Example 1, the results are shown in Table-7.
Table-7
pH ORP Chlorine concentration Disinfecting / sterilizing effect mixed water 4 1040 mV 75 ppm 0
5 980 mV 75 ppm 0
6 920 mV 70 ppm 0
7 880 mV 70 ppm 0
8 820mV 65ppm 0
Anode electrolyzed water 2.9 1168 mV 80 ppm 0
Cathode electrolyzed water 12.4 -236 mV 0 1

In contrast to Example 1, the ORP of the mixed water of Example 4 is high. Therefore, compared with the mixed water of Example 1, it can be expected that the mixed water of Example 4 will have a higher disinfection / sterilization effect.
Therefore, the electrolyzed water obtained using the electrolyzer provided with the bypass line 14 is preferable.

[Example 5]
In Examples 1 to 4, the mixing ratio of the anode electrolyzed water and the cathode electrolyzed water is adjusted by the valve 16.

However, in Example 5, the capacity of the cathode chamber from which the cathode electrolyzed water led to the water storage tank 12 is drained is made smaller than the capacity of the anode chamber 1. Even in this case, the mixing ratio of the anode electrolyzed water and the cathode electrolyzed water can be adjusted.
That is, the cathode chamber of the three-chamber electrolytic cell shown in FIG. 1 was divided into two chambers 2A and 2B by the partition plate 18. That is, a three-chamber electrolytic cell shown in FIG. 8 was prepared.

  N partition plates (N is an integer of 2 or more) are provided, the cathode chamber is divided into (N + 1) chambers, and the cathode electrolyzed water from 1, ..., (N-1) chambers is supplied. It may be used. For example, when the cathode chamber is divided into five chambers, the cathode electrolyzed water from only one chamber is added to the anode electrolyzed water, the cathode electrolyzed water from a total of two chambers is added to the anode electrolyzed water, the total from three chambers The amount of cathode electrolyzed water used for mixing is different from the case where the cathode electrolyzed water is added to the anode electrolyzed water. Therefore, the pH of the mixed water of anode electrolyzed water and cathode electrolyzed water is different. In addition, from a viewpoint which does not have a bad influence on a human body, preferable pH is 4-8. More preferably, it is 6-8. Most preferred is 7.4 (blood pH value). However, there is one case where mixed water having some characteristics is obtained, but there is only one mixed water under optimum conditions. Therefore, it is sufficient to divide the cathode chamber so as to obtain the optimum mixed water, so that only one partition plate is sufficient. Therefore, in the present embodiment, the case where the cathode chamber 2 is divided into two chambers 2A and 2B will be described.

The three-chamber electrolytic cell shown in FIG. 8 was incorporated in the water supply / drainage line shown in FIG.
And it carried out similarly to Example 1 and obtained mixed water with pH 7.4.

Since the disinfection / sterilization effect, ORP, and residual chlorine concentration of this mixed water were examined in the same manner as in Example 1, the results are shown in Table-8.
Table-8
pH ORP Chlorine concentration Disinfection / sterilization effect mixed water 7.4 860 mV 75 ppm 0

[Example 6]
Examples 1 to 5 use only one three-chamber electrolytic cell (electrolyzer).
However, a plurality of three-chamber electrolyzers (electrolyzers) can be used. For example, two three-chamber electrolytic cells (electrolyzers) are used. Three or more three-chamber electrolyzers (electrolyzers) may be used, but there is no particular advantage of using three or more. Therefore, in this embodiment, the case where two are used will be described.

  That is, two three-chamber electrolyzers (electrolyzers) used in Example 1 were prepared, and a water supply / drainage line type device shown in FIG. 10 was produced. That is, the pipes are connected so that all of the anode electrolyzed water and cathode electrolyzed water from the first three-chamber electrolytic cell are sent to the water storage tank 12. On the other hand, the pipe is connected so that only the anode electrolyzed water is sent from the second three-chamber electrolytic cell to the water storage tank. A pipe 9 is connected so that the saturated saline solution is sent to the intermediate chamber of the first three-chamber electrolytic cell through the intermediate chamber of the second three-chamber electrolytic cell.

Furthermore, the electrolysis voltage (electrolysis current) in the first three-chamber electrolytic cell or the second three-chamber electrolytic cell can be adjusted by the output from the pH sensor 17.
That is, the anode electrolyzed water is obtained from two three-chamber electrolyzers, and the cathode electrolyzed water is obtained from one three-chamber electrolyzer. The amount of anode electrolyzed water obtained from the second three-chamber electrolyzer is adjusted by adjusting the electrolysis voltage (electrolysis current) in the second three-chamber electrolyzer.

Incidentally, pure water was supplied to the anode chamber 1 of the first electrolytic cell and the second electrolytic cell at a flow rate of 0.5 L / min. Also, pure water was supplied to the cathode chamber 2 of the first electrolytic cell and the second electrolytic cell at a flow rate of 0.25 L / min. The electrolysis current of the first electrolyzer was 11A. The electrolysis current of the second electrolyzer was controlled so that the pH of the water storage tank was 7.4. Incidentally, the electrolysis current of the second electrolysis apparatus was 10.5A.
And it carried out similarly to Example 1 and obtained mixed water with pH 7.4.

Since the disinfection / sterilization effect of this mixed water, ORP, and residual chlorine concentration were investigated in the same manner as in Example 1, the results are shown in Table-9.
Table-9
pH ORP Chlorine concentration Disinfecting / sterilizing effect mixed water 7.4 849 mV 55 ppm 0

[Example 7]
Example 7 and Example 6 differ only in the connection form of the pipe. That is, in Example 6, the anode electrolyzed water from the anode chamber of the second three-chamber electrolyzer is supplied to the cathode chamber of the first three-chamber electrolyzer (see FIG. 11).
And it carried out similarly to Example 1 and obtained mixed water with pH 7.4.

Since the disinfection / sterilization effect, ORP, and residual chlorine concentration of this mixed water were examined in the same manner as in Example 1, the results are shown in Table-10.
Table-10
pH ORP Chlorine concentration Disinfecting / sterilizing effect mixed water 7.4 850 mV 60 ppm 0

[Example 8]
Two three-chamber electrolyzers of Example 3 (the surface of the anode electrode 6 was covered with a non-woven fabric made of Teflon) were used. And the water supply / drainage line was comprised as shown in FIG. In addition, the water supply / drainage line of Example 8 is provided with the anode chamber bypass line 14 in the water supply / drainage line of FIG. In FIG. 12, reference numeral 18 denotes a hydrogen gas deaeration device provided in the middle of a pipe 15 connecting the cathode chamber outlet 2 b and the water storage tank 12. And safety is improved by this deaeration device.
And it carried out similarly to Example 1 and obtained mixed water with pH 7.4. The flow rate ratio of pure water flowing through the anode chamber 1 and the bypass line 14 is the former: the latter = 1: 10.

Since the disinfection and sterilization effect of this mixed water, ORP, and residual chlorine concentration were investigated like Example 1, the result is shown in Table-11.

[Example 9]
Two three-chamber electrolyzers of Example 3 (the surface of the anode electrode 6 was covered with a non-woven fabric made of Teflon) were used. The water supply / drainage line was configured as shown in FIG. In addition, the water supply / drainage line of Example 9 is provided with the anode chamber bypass line 14 in the water supply / drainage line of FIG.
And it carried out similarly to Example 1 and obtained mixed water with pH 7.4. The flow rate ratio of pure water flowing through the anode chamber 1 and the bypass line 14 is the former: the latter = 1: 10.

Since the disinfection / sterilization effect, ORP, and residual chlorine concentration of this mixed water were examined in the same manner as in Example 1, the results are shown in Table-12.

And it carried out similarly to Example 1 and obtained mixed water with pH 7.4. The flow rate ratio of pure water flowing through the anode chamber 1 and the bypass line 14 is the former: the latter = 1: 10.

Since the disinfection / sterilization effect, ORP, and residual chlorine concentration of this mixed water were examined in the same manner as in Example 1, the results are shown in Table-13.

[Example 11]
The mixed water of the anode electrolyzed water and the cathode electrolyzed water obtained in Examples 1 to 10 was examined for how much the disinfecting / sterilizing effect was maintained.

In the above, the disinfection / disinfection effect was investigated using Escherichia coli.
However, in Example 11, it investigated using the spores of Bacillus subtilis. Specifically, 1 ml of a solution containing 1.0 × 10 ⁶ cells / ml of Bacillus subtilis spores and 10 ml of electrolyzed water were mixed. This solution was smeared on an agar medium and cultured at 25 ° C. for 24 hours. And since the number of Bacillus subtilis was investigated, the result is shown in Table-14. In Table-14, “0” indicates a case where Bacillus subtilis was not observed. "1" shows the case where the number of Bacillus subtilis is 1-10. “2” indicates a case where the number of Bacillus subtilis is 11 to 100. “3” indicates that the number of Bacillus subtilis is 101 to 1000. “4” indicates a case where the number of Bacillus subtilis is 1001 to 10,000. “5” indicates a case where the number of Bacillus subtilis is 10001 or more.

The following can be understood from Table-14 to Table-16.
(1) Even if it is mixed water of anode electrolysis water and cathode electrolysis water, when electrolysis water is what is based on a two-chamber electrolysis device, the disinfection and disinfection effect is low.
(2) A solution obtained by adjusting the pH of anode electrolyzed water using a three-chamber electrolyzer with caustic soda has a low disinfection / sterilization effect. It is inferior to anode electrolyzed water that is not pH adjusted.
(3) Mixed water of anode electrolyzed water and cathode electrolyzed water using a three-chamber electrolyzer has a high disinfection / sterilization effect. The pH of the mixed water is higher than the pH of the anode electrolyzed water alone. That is, the mixed water has low acidity. Therefore, the mixed water has a low adverse effect on the human body.
(4) When Example 1 and Examples 3-10 are contrasted, the electrolyzed water by the apparatus used in Examples 3-10 is excellent in the disinfection and sterilization effect.
In Examples 3, 8, and 9, the surface of the anode electrode of the three-chamber electrolysis apparatus was covered with a nonwoven fabric (Technology A).
In Examples 4 and 10, a bypass line was provided in the anode chamber of the three-chamber electrolysis device (Technology B).
In Examples 5 and 10, a partition plate was provided in the cathode chamber of the three-chamber electrolysis device (Technology C).
Examples 6, 7, 8, and 9 are those using a plurality of three-chamber electrolyzers (Technology D).
Especially, the thing of Examples 8-10 is much more excellent in the disinfection and disinfection effect.
Therefore, even if it is the same three-chamber electrolysis apparatus, the electrolyzed water by the apparatus which employ | adopted not only one of technique A, B, C, D but two or more is more preferable.

The test was repeated 12 months after the production of the mixed water of anode electrolyzed water and cathode electrolyzed water, and the results (the number of bacteria) are shown in Table-17.

Mixed water (Example 9, pH 7.4) 1 0 0
Mixed water (Example 10, pH 7.4) 1 1 0

According to this, it can be seen that the mixed water of the present invention does not weaken the disinfection / sterilization effect even if it is stored for a long time after production. Therefore, a large amount can be prepared in advance. This leads to cost reduction.

[Example 12]
The wound treatment effect of the mixed water of the present invention was examined. The results are shown in Table-18.
In this example, the mixed water obtained in Example 9 was used. For comparison, the anode electrolyzed water having a pH of 2.5 obtained in Example 1 was used. In addition, physiological saline was used for comparison. For comparison, physiological saline having a pH of 7.4 in which 50 ppm of hypochlorous acid was dissolved was used.

In the test, after shaving the back of the rat, 1 cm ² of skin was excised to form a wound site. And only said first 7 days, said aqueous solution was dripped twice a day so that it might not overflow from a wound surface. Thereafter, the wound site was left and the area of the wound site was determined by the plani method.

Table-18
0 days 7 days later 14 days later 24 days later Mixed water 1.10 0.25 0.01 0
Anode electrolyzed water 1.04 0.38 0.03 0
Saline 1.01 0.70 0.11 0.05
Hypochlorous acid aqueous solution 0.98 0.55 0.10 0.04

According to this, it turns out that the mixed water of this invention is excellent also in wound healing.

Anode healing water also has a wound healing effect. However, it can be seen that the mixed water of the present invention heals faster.
Moreover, since the mixed water of the present invention has a lower acidity than the anode electrolyzed water, there is little adverse effect on the human body.
