Abstract: The peeling member is disposed inside the inner tank. The switching mechanism is provided for switching between the state of rotating the peeling member in the interlocking manner with the inner tank and the state of being disconnected the peeling member from the inner tank. With the peeling member disconnected from the inner tank, one of them is rotated, the used paper diaper stored is peeled off from the inner surface of the inner tank, and then, the used paper diaper processed in the processing tank is discharged from the bottom of the processing tank to the take-out unit via the opening and closing unit.

Abstract: Provided is a used paper diaper processing apparatus in which a water absorption function of a superabsorbent polymer that absorbs water contained in excrement is lowered and water is removed by mixing the superabsorbent polymer and a chemical containing divalent metal ions in an outer tank, and in which weight is reduced by dehydration after an amount of water contained in a used paper diaper is lowered. In the apparatus, a lower portion of the outer tank can be opened and closed, so that weight reduction processing and a series of operations including taking-out are possible. Since an operator is not required to take out the used paper diaper after processing directly from the outer tank, it is possible to reduce work and hygiene burdens on the operator.

Abstract: A used paper diaper processing apparatus includes at an upper portion of a processing tank, a plurality of holding units capable of holding used paper diapers, and a continuous put-into unit including a holding unit rotation drive unit that rotationally drives each of the holding units at a put-into position I above an opening connected to the processing tank and a standby position II other than the put-into position. When the holding unit is rotated by the holding unit rotation drive unit and positioned at the put-into position, the used paper diaper held by the holding unit is put into the processing tank from the opening.

Abstract: A processing liquid is generated by mixing a chemical and water in a processing liquid generation region disposed below an inner tank. By further supplying water to raise a water level, the processing liquid is supplied from below the inner tank. This prevents a used paper diaper from coming into contact with water containing no chemical.

Abstract: In a processing tank where a processing liquid is stored up to a first water level, first stirring processing that removes water from a used paper diaper is performed to remove the water from the used paper diaper. Then, the processing liquid is stored up to a second water level higher than the first water level, and second stirring processing that separates excrement contained in the used paper diaper from the used paper diaper is performed to separate the excrement from the used paper diaper. After that, dehydration processing is performed.

Abstract: A liquid treatment device that achieves an effective treatment by forcibly contacting a swirl flow of a hydrogen peroxide-containing treated liquid with a liquid to be treated that has been processed to contain copper ions or iron ions includes a rod-like first electrode, a plate-like second electrode formed of a copper- or iron-containing metal, and a first treatment vessel that causes a liquid to swirl and generate a gas phase in a swirl flow of the liquid. A pulse voltage is applied to the generated gas phase to generate a plasma. The second electrode serves as an anode, and reaches inside of a supply section for a liquid to be treated. The liquid to be treated containing the generated copper ions or iron ions is forcibly brought into contact with hydrogen peroxide generated by the plasma. In this way, the Fenton's reaction effectively takes place, and the liquid treatment performance improves.
