PROBLEM TO BE SOLVED: To obtain a device for removing dissolved ozone which does not required maintenance, is low in an initial cost and running cost and is small in size. SOLUTION: The dissolved ozone remover comprises a gas mixing pipe 1 which has a water feeding hole 2 connected to piping for feeding dissolved ozone water and a drain hole 3, is provided with a shrunk section 3 in mid-way of the water fill and the drain hole and is provided with a gas injection section 4 for injecting gas not containing ozone to the shrunk section and a gas-liquid separating vessel 6 having a gas vent valve 7 in the rear stage of the gas mixing pipe. The remover is constituted to inject the gas not containing the ozone from the gas injection section to the ozonized water, to separate the gas containing the ozone and the water by the gas-liquid separating vessel and to remove the dissolved oxygen. Equally good alternative is to install a gas- liquid mixer between the gas mixing pipe and the gas-liquid separating vessel.
