Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is a circulation purification system for hot springs for the purpose of reusing the resources of the hot springs and purifying them while circulating them for a certain period of time.

[0002]

2. Description of the Related Art Hot spring water tends to decrease in amount due to overexploitation due to overexploitation, and in order to prevent this, there are various methods to reduce the consumption of hot spring water by reusing resources. It is being appreciated. One of the most widely used methods is a circulation filtration method using a filter by physical adsorption. That is, the hot spring water in the bath tub is circulated, and in the circulation path, hair, towel cloth scraps, dust, etc. are removed by a strainer, and contaminant contaminants are filtered by a physical adsorption filter using sand, activated carbon, etc., Sterilize harmful microorganisms such as Escherichia coli and spoilage bacteria by heating or chemicals,
In addition, it is a system in which a malodor is removed by a filter, chemicals, enzymes, etc., and the purified hot spring water is heated to a proper bathing temperature by a boiler and then reinjected into the bath.

[0003]

In the conventional circulation purification method carried out as described above, it is easy to remove hair, towel cloth dust, dust and the like, but the physical adsorption filter uses high-quality activated carbon. Equipment costs, filter media replacement costs, operation and maintenance costs, etc. increase due to use, so there is a limit to the scale and capacity of hotels and ryokan, so it is difficult to extend the reuse period of hot springs. is there.

Therefore, in recycling for a short period of time, it has been achieved to filter the pollutants to improve the transparency, but the degree of purification is still insufficient, and in particular, the removal of bad odors and harmful microorganisms. There are many problems regarding the sterilization of, and the current situation of hotels, inns, etc. varies depending on the drug and the day of the week,
The maximum period for recycling and reuse is about one week. Therefore, many problems have been raised in terms of effective use of hot springs and purification costs.

[0006]

The operation of the present invention will be described with reference to FIG. The polluted hot spring water 2 in the bathtub 1 is circulated through the circulation path by the pump 4, and hair, towel cloth waste, dust, etc. mixed by the conventional strainer 3 provided in the circulation path are removed.
It is filled with sand, soil, charcoal, activated carbon, etc. and filtered by a conventional filter 5 having a physical adsorption function.

The hot spring source filtered is then heated by the boiler 8. According to the method of the present invention, pollutants are treated by aerobic and anaerobic microorganisms in the microbial septic tank 9 provided upstream of the filter 5. , One or more kinds of metal (for example, copper, alumina, zinc, potassium, calcium, sodium, etc.) ion generators 6 and 1 installed on the downstream side of the microbial septic tank 9.
One or more non-metals (eg chlorine, sulfur, carbon compounds, etc.)
Ion generator 7, or two different potential metal (eg, copper and zinc) positive and negative potential ion generators 6 and one or more non-metal ion generators 7 to purify hot spring water after microbial purification Let At this time, the front and rear positions of the metal ion generator 6 and the nonmetal ion generator 7 with respect to the filter 5 and the front and rear positions of the metal ion generator 6 and the nonmetal ion generator 7 are not limited.

The hot spring water to be distributed contains, in addition to microorganisms mixed from the microbial septic tank 9 by metal ions generated by the metal ion generator 6, for example, copper ions, harmful microorganisms contained therein, such as pathogenic bacteria, molds, and spoilage bacteria causing bad odor. Are sterilized. In addition, ions such as potassium, calcium and sodium generated by the metal ion generator 6 and the non-metal ion generator 7
Due to the ions of chlorine, sulfur, etc., generated, pollutants and malodorous substances contained therein are adsorbed and removed by ion exchange.

Therefore, according to the method of the present invention, in the process in which the hot spring water 2 circulates in the circulation route, the contained malodorous substances and contained harmful substances which could not be removed only by the filter due to the physical adsorption action are treated by the action of microorganisms and ions It is removed by adsorption to be purified, and harmful microorganisms such as contaminating pathogens and spoilage bacteria that generate an offensive odor, and propagated microorganisms are sterilized by the action of metal ions.

The circulating hot spring water targeted by the method of the present invention contains a large amount of various substances contained in the hot spring water and various pollutants discharged from the bathed human body, and most of these substances are contained. Since it is an ionized substance, the ionization phenomenon is much more remarkable than rainwater or river water. Further, since the temperature is always higher than that of water, it promotes the growth of microorganisms, ion exchange and ion adsorption phenomena, and the purification action is remarkably improved.

The purified hot spring water 2 is then heated by the boiler 8 to a bath temperature taking cooling into consideration and poured into the bath 1 if necessary. At the same time, the phenomenon of calcium components adhering to the pipe and boiler 8 of the passage to form a scale is also prevented by the action of ions.
