  As shown in FIG. 3, in the first tank 18a and the second tank 18b constituting the filth treatment tank 13, filth decomposition processing means is provided. The decomposition processing means includes rotating shafts 19a and 19b extending in the longitudinal direction in the processing chambers 24a and 24b, a plurality of stirring blades 32a and 32b provided along the rotating shafts 19a and 19b, and the rotating shafts. It consists of cross-shaped rotary blades 36a and 36b provided at one end of 19a and 19b. Rotational force from the motor 37 in the drive control device 17 is transmitted to the rotary shafts 19a and 19b via the cam mechanism 30, and the rotary shafts 19a and 19b are rotated in opposite directions by the cam mechanism 30. The motor 37 is driven by an operation switch (not shown).

  As shown in FIG. 4 (a), the stirring blades 32a and 32b attached along the rotary shafts 19a and 19b include a ring portion 33 for fixing through the rotary shafts 19a and 19b, and the ring portion. It is comprised with the metal plate-shaped piece (blade part 34) standingly arranged by 33. FIG. As shown in FIG. 4B, the blade portion 34 is set to an angle α of approximately 45 degrees with respect to the longitudinal direction of the rotary shafts 19a and 19b. By setting such an angle α, the biochip 14 and the filth 10 can be stirred and moved in one direction along the longitudinal direction of the rotary shafts 19a and 19b. The blade 34 is provided with a plurality of large and small holes 31a and 31b. These holes 31a and 31b are provided so that the resistance when the biochip 14 and the filth 10 are agitated is reduced and the rotation is smoothly performed, and the biochip 14 and the filth 10 are sufficiently agitated. The number, size, arrangement, and the like of the holes 31a and 31b are appropriately designed according to the material and size of the biochip 14, the amount of treatment of the filth 10, and the like. Thus, by providing the large and small hole portions 31a and 31b having different sizes, a part of the biochip 14 that hits the stirring blades 32a and 32b can be released from the hole portions 31a and 31b. Even when the amount is temporarily increased, stirring can be performed smoothly without applying an excessive force to the stirring blades 32 a and 32 b, and an excessive load is not applied to the motor 37. Further, by providing the holes 31a and 31b, the filth 10 is hardly attached to the surfaces of the stirring blades 32a and 32b, and the filth 10 can be sufficiently mixed with the biochip 14 and can be easily cleaned. The shape of the holes 31a and 31b is preferably a circular shape or an elliptical shape as shown in FIG. Needless to say, the mounting angle α of the blade portion 34 is not limited to 45 degrees.

  In this embodiment, as shown in FIGS. 1 and 3, the stirring blades 32a and 32b are spaced at regular intervals so that adjacent stirring blades are alternately displaced by 180 degrees on the respective rotation shafts 19a and 19b. A plurality are provided for each. Further, the stirring blade 32a of the rotating shaft 19a disposed in the one processing chamber 24a and the stirring blade 32b of the rotating shaft 19b disposed in the other processing chamber 24b substantially correspond to each of the rotating shafts 19a and 19b. Each is attached to the position, and the attachment angle between the stirring blades 32a and 32b at the corresponding positions is set to be shifted by about 90 degrees. In this way, the waste disposal tank is provided by alternately shifting the mounting positions of the stirring blades adjacent to each other on the same rotation shaft or between the stirring blades at corresponding positions on the pair of rotation shafts extending in parallel. The biochip 14 spread in 13 can be uniformly stirred without being biased to one place smoothly. Note that the stirring blades 38a and 38b and the stirring blades 39a and 39b provided opposite to the end portions of the rotary shafts 19a and 19b have a smooth flow between the processing chamber 24a and the processing chamber 24b. In some cases, the mounting angles are the same. As described above, the angle between the adjacent stirring blades or the angle of the stirring blades 32a and 32b attached at substantially corresponding positions on the rotary shafts 19a and 19b is not limited to the above 180 degrees or 90 degrees. Of course.

  Next, the operation for decomposing the filth in the filth treatment tank 13 will be described with reference to FIGS. An appropriate amount of biochip 14 is spread in the processing chambers 24a and 24b of the first tank 18a and the second tank 18b. When the operation switch is turned on after the filth 10 is excreted thereon, as shown in FIG. 6, a drive operation command is transmitted to the motor 37 provided in the drive control device 17, and a pair of rotations are performed via the cam mechanism 30. The shafts 19a and 19b rotate simultaneously. Then, as shown in FIG. 7, the inside of each processing chamber 24a, 24b is sequentially moved in the direction of the arrow while the filth 10 is entangled with the biochip 14 by the rotation of the stirring blades 32a, 32b. Further, at the end of the processing chamber 24a, the sewage 10 and the biochip 14 are entangled by the rotating blades 36a and the stirring blades 38a and 38b, and transferred to the processing chamber 24b, and at the end of the processing chamber 24b, The rotary blade 36b and the stirring blades 39a and 39b are transferred to the processing chamber 24a. Thus, the waste 10 is gradually decomposed while circulating between the processing chambers 24a and 24b. The drive control device 17 operates with an AC power source for home use, but a power source using solar power generation or small wind power generation can also be used in a place where there is no power supply facility.

  In the filth decomposition operation, the agitating blades 32a and 32b of the rotary shafts 19a and 19b are rotated inward or outward several times, so that the filth 10 excreted on the biochip 14 and the biochip 14 are combined. Although it is possible to circulate evenly in the waste disposal tank 13, by setting the rotation direction and speed, or the rotation speed and interval in the sequencer 29 provided in the drive control device 17, as shown in FIG. An efficient disassembly treatment operation is possible. For example, immediately after the filth 10 is excreted in the filth treatment tank 13, the stirring blades 32 a and 32 b of the rotary shafts 19 a and 19 b are rotated once inward from each other. By this operation, the filth 10 excreted at an arbitrary location in the filth treatment tank 13 can be adapted to the biochip 14. Next, the stirring blades 32a and 32b of the rotary shafts 19a and 19b are mutually switched to the rotation in the outer direction, and are continuously rotated several times. By this rotation, the filth 10 is further agitated and mixed with the biochip 14, and moves in the processing chambers 24 a and 24 b of the filth treatment tank 13 together with the biochip 14. The rotation speed can be controlled directly by using a stepping motor, in addition to being detected by a count sensor (not shown) provided in the cam mechanism 30. By repeating such a series of operations, the filth 10 circulates without staying in one place, so that the decomposition process can be promoted. This series of operations can be performed at an arbitrary timing, for example, by the user arbitrarily operating the above-described operation switch provided in a toilet unit or the like installed on the waste disposal unit 11 of the present embodiment. In addition, it can be executed at predetermined time intervals by setting the timer. In addition, several temperature sensors (not shown) are installed in the waste disposal tank 13 and are controlled by a temperature adjusting unit 44 provided in the drive control device 17 so as to maintain a preset temperature. As for the set temperature, it is desirable to appropriately determine the optimum temperature for the decomposition treatment of filth according to the use conditions. In this embodiment, as described above, since the heater 35 and the heat insulating member 25 are mounted on the outer surface of the waste disposal tank 13, the set optimum temperature can be maintained for a long time.

  FIG. 8 shows an embodiment of a temporary toilet 40 in which the above-described waste disposal unit 11 is incorporated in the lower part of a simple toilet unit 41. When the temporary toilet 40 is actually used, the temporary toilet 40 is accommodated in the frame 12 with the lid 45 attached to the upper surface of the waste disposal tank 13. The lid body 45 is provided with an opening 46 for dropping filth from the toilet unit 41, and is formed in a mountain shape so that the central portion is raised.
