However, the conventional method for treating used paper diapers has the following problems. When a used disposable diaper is discarded in its original amount as general waste, the disposal capacity and weight are large, and there is a problem that the odor increases if left unused until the waste collection date. In the case of incineration, it is necessary to incinerate at a high temperature in order to prevent the generation of harmful substances such as dioxins, and the equipment cost of such incinerators is extremely high, and the processing time is too long. In addition, the installation location also needs to be considered with respect to local residents and the surrounding environment, which is greatly limited. In facilities such as hospitals and nursing homes, nurses must transport or store used disposable diapers to a designated place or incinerator in the meantime, which puts a heavy burden on post-processing and management efforts.

It is molded by. The rotary drum 7 has a large number of through-holes 11 having a diameter of, for example, 4 to 10 mm on its peripheral wall. The opening diameter of the through hole 11 is 4
The reason for setting to mm10 mmφ is that when an experiment was actually conducted with a disposable diaper, if it was less than 4 mmφ, it would not be possible to pass through even a turbid aqueous solution that had been separated and disassembled. This is because insoluble matter such as vinyl to be passed also passes through the through hole 11. The optimum opening diameter of the through hole 11 was 6 to 8 mmφ in the experiment.

After the lid 2 is closed, the on-off valve 34 of the water supply means 5 is opened to supply water from the water supply pipe 33 into the outer shell 6, and a predetermined amount (rotary drum) When the lower portion 7 is immersed in water, for example, the water level shown in FIG. 2), the on-off valve 34 is closed to stop the water supply (water supply step). At this time, the on-off valve 36 of the discharging means is closed. The amount of water supplied into the outer shell 6 depends on the rotation drum 7
Water level meter (not shown) that divides the space between the center and the lower end into 10 equal parts
Is provided, and the scale of this water level meter (the lower end is zero and the center height of the rotating drum 7 is 10) is in the range of 2 to 7. When water is supplied beyond the scale 7, the disposable diaper floats even if the rotary drum 7 is reciprocated and the efficiency of disassembly and separation is reduced. When the water level is in the range of scales 3 to 5, the disassembly and separation can be performed most efficiently. Further, the water in the outer shell 6 is provided with the deodorant charging device 25 and the chemical charging device 2.
In step 6, a deodorant, a bactericide, or the like is added as necessary.
Further, in this embodiment, since the upper portion of the outer shell 6 and the outlet side of the drain valve are connected by the overflow pipe 44, if the water is excessively supplied, the overflow pipe 44
The surplus water can be drained through. The overflow pipe 44 is turned halfway to form an odor trap.

Next, the power supply of the heater 22 is turned on, and the water in which the used disposable diaper accommodated in the rotary drum 7 is immersed is heated and sterilized (sterilization step). The heating temperature in this sterilization process is set to, for example, 80 degrees Celsius, and the heating temperature is confirmed by a temperature sensor. Since the heating temperature of the heating means is 80 degrees Celsius or more, the sterilization of wastewater containing waste can be effectively performed. The rotating drum 7
When a bactericide is added to the water inside, the sterilization effect can be enhanced.

Thereafter, or simultaneously with the start of the sterilization step, the motor 16 is started to rotate the rotary drum 7 to generate a water flow in the rotary drum 7, thereby immersing the disposable diaper in the rotary drum 7 in water. Separated and disassembled in the state (disassembly step). The water flow is turned into a forward / reverse reversal water flow by driving the motor 16 forward / reverse, that is, by rotating the rotary drum 7 back and forth. The used water diaper stored in the rotating drum 7 is separated and disassembled into a water-soluble substance (paper, excrement, etc.) and an insoluble substance (plastic) by the inverted water flow. In this embodiment, the rotating drum 7 has the stirring protrusion 1.
2, the disposable diaper is hooked on the stirring projection 12 and stirred, so that the separation and disassembly is promoted. The rotation speed of the rotary drum 7 is such that the peripheral speed of the outer periphery of the drum is 60 to 120 m / mi.
When n is within the range, separation and disassembly can be performed efficiently. Further, the separation and disassembly can be performed by rotating the rotating drum 7 in one direction, but the reciprocating rotation is more efficient.
