PROBLEM TO BE SOLVED: To provide a fluid purifier which effectively uses the oxidative decomposition energy of organic floating substances contained in waste water for raising the temperature of waste water in a reaction tank, requiring reduced cleaning operation frequency for the reaction tank.SOLUTION: The fluid purifier includes a reaction tank 20 in which the fluid mixture of waste water W and air are heated and pressurized, so that organic substances in the waste water W are decomposed by oxidation to achieve purification of the waste water W. As a pretreatment prior to inflow of the waste water W into the reaction tank 20, the waste water W in a heated and pressurized state is passed through a filter without mixing with air in a pretreatment unit 100. |
