PROBLEM TO BE SOLVED: To provide a fluid purification device capable of suppressing occurrence of blockage due to carbonized organic matters in a raw water conveying pipe 15.SOLUTION: A fluid purification device includes: a reaction tank 20 decomposing organic matters in waste water W by an oxidizing reaction while heating and pressurizing a fluid mixture of the waste water W and air A to purify the waste water W; and a raw water conveying pipe 15 connected to the reaction tank 20 to send only the waste water W among the waste water W and the air A toward the reaction tank 20. In the fluid purification device, a heat insulation layer having a thermal conductivity lower than that of a pipe base body is arranged on an inner circumferential face of the pipe base body in the raw water conveying pipe 15. |
