Abstract

PROBLEM TO BE SOLVED: To strongly and inexpensively perform sterilization without leaving a component which is undesirable from an aspect of health or the utilization of water such as residual chlorine. SOLUTION: This method is a sterilizing method using oxidation power of halogen molecules such as chlorine but chlorine is generated in water by electrolysis without being introduced into and added to water to sterilize water and chlorine remaining in water after treatment is electrolytically reduced to be returned to the origin. In order to enable the electrolysis of a dilute soln., porous electrodes 1, 2 are used to increase a reaction surface area. Water permeable electrodes 1, 2 are used while water is allowed to flow across the electrodes to perform electrolysis. The supply of chloride ions to an electrolytic reaction surface is dynamically accelerated.

Field of the Invention The present invention relates to a method for sterilizing industrial water, agricultural water, domestic water, sports and leisure water, and the like. In recent years, the demand for water has been steadily increasing due to the improvement of living standards and the expansion of industries, but rainfall has tended to decrease in the future due to a decrease in snowfall, etc. It is a theme. For this, it is important to circulate the water, and in this case,
May cause health problems such as bacterial growth,
There is a need for a powerful and low cost sterilization method. The method according to the present invention is a method particularly suitable for disinfecting water such as pools, baths for 24 hours, bio, and hydroponic culture, which can strongly disinfect water and have no residual chlorine. .

う用水の場合には問題となっている。2. Description of the Related Art As a method of disinfecting water, a method generally used is to introduce chlorine and sterilize it by its oxidizing power. Since this method is inexpensive and has excellent sterilizing power, most of the methods such as sterilization of water supply and pool water are performed by this method. This method is the most reliable method that keeps sterilization state for a long time because there is residual chlorine, but it is a problem in the case of water that dislikes chlorine content for corrosion and growth disorders and even human health. .

And then cooling.

常温の用水には適さない上に設備費も非常に高い。[0004] However, the method of adsorbing and removing chlorine with activated carbon is expensive for activated carbon and is suitable for treating a small amount of water, but is not preferable for a large amount. Although the method using ozone or ultraviolet irradiation has been put to practical use, there are problems such as extremely high equipment cost and weak sterilizing power. The method of cooling after high temperature sterilization is 100
% Heat exchange is not possible, so it is good for hot water but not suitable for normal temperature water, and the equipment cost is very high.

Further, there is a problem of treating caustic soda which is a by-product.

However, this is possible when using a solution with a high salt concentration and the distance between the electrodes is relatively narrow, and in the case of a very dilute salt solution such as ordinary water, decomposition takes a very long time. In short, at first glance, almost no electricity flows and no generation of chlorine is observed, so that it is practically impossible to sterilize water by electrolysis.

高濃度溶液の場合と同じような反応速度が可能となる。Means for Solving the Problems In order to solve the above-mentioned problems, the present invention is firstly characterized in that a porous electrode having water permeability is used. Generally, rod-shaped or plate-shaped electrodes are used for electrolysis.However, such electrodes have a small surface area where the electrolytic reaction takes place, so there is a problem with electrolysis of highly concentrated solutions containing a large amount of ions. However, the electrolysis of a very dilute salt solution, which is the object of the present invention, requires a very long time. In order to solve this problem, the present invention has solved the problem by increasing the reaction surface area by using porous carbon or the like having a very large surface area as an electrode. The use of the porous carbon electrode of the present invention increases the reaction surface area by tens of thousands to hundreds of thousands, so that the same reaction rate can be achieved even in the case of a salt solution in the order of ppm as in the case of a high concentration solution.

る。However, simply increasing the surface area of the electrolytic reaction by using a porous electrode causes the electrolytic reaction of ions at or near the surface to occur immediately, but the supply of ions to the reaction surface is not enough to continue the reaction. Can not. Again, this is not a practical problem in the case of high-concentration solutions due to the large amount of ions, but in the case of commonly used water, the amount of ions is on the order of tens of thousands of Only happens. Therefore, in the present invention, the second characteristic is that the electrolysis is performed while flowing water to be sterilized between the porous electrodes, and the electrolytic reaction is promoted by dynamically supplying ions to the surface of the electrodes. It is.

Therefore, stirring or flowing the solution is completely out of the question, but in the present invention, the product is not obtained. It is not an object, but rather that the water after sterilization is preferably in its original state, which is what can be done, which is a very characteristic feature of the present invention.

態となる。The direction of flowing water between the electrodes must always flow from the anode to the cathode, and the object of the present invention cannot be achieved in the reverse direction. Halogen molecules such as chlorine generated at the anode dissolve in water and are transported together with the water to the cathode, while the oxidizing power of the halogen molecules kills bacteria in the water. The remaining halogen molecules are immediately reduced after being adsorbed on the surface of the cathode such as porous carbon, and return to the original halogen ions. Since the halogen molecules used for sterilization during the flow between the electrodes become ions, the hydrogen and hydroxide corresponding to the halogen molecules are theoretically generated at the cathode.
Since the hydroxide is equivalent to the halogen, it is neutralized to its original state.

There is no problem because there are halogen ions mainly containing chloride ions of m to several hundred ppm. If necessary, it is possible to add an optimal amount of salt, and in the case of circulating water, it is desirable to control the amount to an optimal amount. In some cases, halogen ions such as bromine and iodine may be more effective.

However, this does not hinder the present invention, but rather has a complementary role. That is, oxygen generated at the anode by electrolysis of water is insoluble in water, but is in an active oxygen state on the surface of the anode, and sterilization is performed by the oxidizing power of water as it passes through this surface. Hydrogen generated at the cathode is a small amount in absolute amount, and there is no danger that hydrogen is diffused into the air by keeping the upper part open.

Denotes a cathode, 3 denotes a DC power supply, and 4 denotes a circular or square tube for flowing water to be sterilized. Water to be sterilized flows through the cylinder from the anode side. Halogen ions such as chlorine ions in the water are electrolytically oxidized while passing through the anode to become halogen molecules such as chlorine molecules and dissolved in the water. The water is sterilized by the oxidizing power of the halogen molecules from the anode to the cathode. After this, water passes through the cathode, but on the cathode surface, the remaining halogen molecules receive electrons from the electrode and are reduced to halogen ions, returning to the original water state. In this way, the water at the inlet and outlet is only sterilized without any deterioration.

In addition, utilizing the strong oxidizing power of halogen molecules and sterilization at a high concentration are possible, and effective sterilization can be performed even on bacteria that cannot be sterilized by ozone or ultraviolet irradiation.
