CIRCULATING WATER STERILIZATION TREATMENT SYSTEM AND CONTROL METHOD OF CIRCULATION WATER STERILIZATION TREATMENT USED THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a sterilizing system that can achieve a sufficient sterilizing effect while securing high safety to the human body.;SOLUTION: A circulation pipe line (P1, P2) for circulating the circulating water from the bath (9), a circulation filtration device (8, 1) interposed therebetween, an ozone injection device (3) branched and connected, a mixed reaction device (4, 5) to be connected, a medicine injection device (7) to be branched and connected, and first and second ozone sensors (S1, S2) provided in the inflow pipe and the outflow pipe. If the first and second ozone sensors exceed the first set value during the "ozone injection operation" in which only the medicine injection device is not operating, the operation of the ozone injection device is stopped and "non-injection" is performed. After switching to the "non-injecting operation", at the time when either the first or second ozone sensor (S1, S2) falls below the second set value, the system is switched to "medicine injection operation" in which only the ozone injection device is not operating.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2019,JPO&INPIT
