PROBLEM TO BE SOLVED: To allow a catalyst in a reaction tank 20 to efficiently exhibit its catalytic performance without installing mixing means for mixing the catalyst beforehand with waste water W before being sent to the reaction tank 20.SOLUTION: A catalyst 25, which promotes the oxidative degradation of organic substances while moving in a reaction tank 20 together with waste water W and air A, is arranged in a reaction tank 20, and a separation mesh 29 for separating the waste water W and the air A from a mixture of the waste water W, the air A, and the catalyst 25 and discharging the separated waste water W and air A from the reaction tank 20. |
