The tank 2 of the decontamination system 1 stores raw water (water). The raw water stored in the tank 2 is supplied to the ozone water generator 3.
The ozone water generator 3 of the decontamination system 1 is connected to the tank 2 via a pipe. The ozone water generator 3 generates ozone water from raw water supplied from the tank 2 via a pipe. Here, ozone water is obtained by dissolving ozone (O3) in water.
The ozone water generated by the ozone water generator 3 is heated to a predetermined temperature so that the person who is put on the ozone water (the person to be decontaminated) does not feel too cold or too hot by the temperature control device. The temperature is adjusted (for example, raised or lowered to 26 to 40 degrees) and supplied to the decontamination unit 4.

  In the decontamination unit 4 of the decontamination system 1, the human body contaminated with the pollutant is decontaminated. As shown in FIG. 1 or FIG. 2, the decontamination unit 4 includes a tent 41, an ozone water spray device 60, a water receiver 43, and a slat 44.

The tent 41 of the decontamination unit 4 in the decontamination system 1 is configured to be able to decontaminate a human body contaminated with a pollutant while standing in the tent 41.
The tent 41 of the decontamination unit 4 is configured to be set up in a short time. The tent 41 of the decontamination unit 4 is constituted by an air tent that can be formed into a dome-shaped three-dimensional structure within a few minutes by blowing air, and can be folded by removing the air, for example. Is done.

The ozone water spraying device 60 of the decontamination unit 4 in the decontamination system 1 applies ozone water to the human body that has been decontaminated by pollutants by spraying ozone water from the ozone water spray port. The ozone water spraying device 60 of the decontamination unit 4 is connected to the ozone water generating device 3 through a pipe, and is configured to spray ozone water whose temperature is adjusted by the temperature control device.
The ozone water spraying device 60 of the decontamination unit 4 is disposed in the tent 41. The ozone water spraying device 60 of the decontamination unit 4 is configured to spray ozone water from above toward a human body contaminated with a contaminant to be decontaminated.

Moreover, in the decontamination system 1, the ozone water is applied so that the difference between the pressure immediately before the ozone water spraying device 60 is sprayed from the ozone water spraying port and the pressure after the ozone water spraying device 60 is sprayed from the ozone water spraying port becomes small. Since it is configured to be sprayable, it is suppressed that the ozone concentration of ozone water decreases before the ozone water sprayed from the ozone water spray port reaches the human body contaminated with the pollutant.
Thus, since the ozone concentration of ozone water is suppressed from decreasing before the ozone water sprayed from the ozone water spray port reaches the human body contaminated with the pollutant, the decontamination system 1 Thus, the human body contaminated with the substance B or the substance C can be decontaminated in a shorter time and more reliably.

In the decontamination system 1, when the pollutant that pollutes the human body is an N (nuclear) substance, the N substance is aggregated after being separated from the human body by the action of aggregating the colloid in ozone water. For this reason, in the decontamination system 1, when filtering the drainage of the ozone water used for decontamination, the aggregated N substance can be easily collected without using a fine filter, The process which removes N substance from waste water can be performed more easily.
In the decontamination system 1, when the pollutant that pollutes the human body is a weakly resistant B substance, the B substance is sterilized and rendered harmless, so that the disinfection treatment of the B substance contained in the waste water becomes unnecessary. . When the pollutant that pollutes the human body is a highly resistant substance B, the disinfection of the substance B proceeds in the process of draining after the ozone water is applied. Disinfection treatment can be easily performed.
