When the waste water containing the peroxide is introduced into the treatment tank 12 through the waste water introducing pipe 16 with such a structure, the waste water rises to the catalyst layer 20 through the gravel tank 18. The wastewater comes into contact with the catalyst in the catalyst layer 20, the peroxide in the wastewater causes a decomposition reaction, and the generated oxygen gas passes through the catalyst layer 20 and floats to the upper portion of the processing tank 12. At this time, since the catalyst of the catalyst layer 20 is not fixed, it is in a fluidized state and has a good contact efficiency with the drainage,
Therefore, the decomposition reaction is also efficiently performed.

Wastewater which has been decomposed by a catalyst of peroxide rises in the catalyst layer 20 and is treated as treated water in the treatment tank 1.
To the upper part of 2. This treated water is accompanied by the oxygen gas and the granular catalyst. The treated water containing the catalyst and oxygen gas flows into the inside of the upper portion of the treatment tank 12 from the lower end portion of the inclined guide plate 22. At this time, the inclined baffle plate 3
Due to the presence of 0, the catalyst / gas-containing treated water does not pass through the outside of the inclined guide plate 22 and is reliably guided to the inside of the inclined guide plate 22. Then, the treated water rises along the guide path inside the inclined guide plate 22, oxygen gas is diffused from the upper end portion of the inclined guide plate 22, and the gas port 1 of the treatment tank 12 is discharged.
4 is released to the outside.

Here, there is a density difference in the treated water between the inside and outside of the inclined guide plate 22 due to the presence or absence of gas. That is, the density of the treated water inside the inclined guide plate 22 is smaller than the density of the treated water outside. As a result, the treated water flowing out from the upper end of the inclined guide plate 22 is
The inclined baffle plate 30 and the lower end portion of the inclined guide plate 22 tend to flow toward the inside of the inclined guide plate 22 through the gap.
Further, since the inclined plate 36 is provided as described above, the treated water containing the catalyst can be more reliably supplied to the inclined baffle plate 3.
0 and the lower end of the inclined guide plate 22 are guided in the gap.
