The operation of the present invention will be described. In the mobile unit toilet of the present invention, the waste treatment tank for fecal urine and the like is partitioned by a wall, and a primary treatment tank, a bulky substance separation tank, and a secondary treatment tank are used.
It consists of a tank. These walls are partition walls as described above and serve as support walls for supporting the floor. The primary treatment tank is a tank that first receives fecal urine and flushing water excreted from the flush toilet, and the bottom of the tank is laid with an air ejection pipe having a large number of air ejection ports to prevent the urine from flowing out of the blower. Air is sent to agitate the dirt, and air is taken in from the floor to the surface of the dirt through an air intake pipe provided in the tank. Aerobic microorganisms mixed from the atmosphere in the primary urine in the primary treatment tank are activated by agitation of air, and the activity causes pretreatment of the urine and urine to be partially converted to hydrogen, nitrogen, carbon dioxide or water. Then, it is discharged to the outside from the exhaust tube provided on the top plate of the tank via the coarse-sized separation tank.

[0008] The pretreated waste flows from the upper portion thereof into the coarse-sized separation tank provided next by an overflow pipe. The pretreated waste that has flowed into the coarse waste separation tank is passed through a net bag as it is to filter the coarse waste, and the wastewater from which the coarse waste has been removed is stored in the tank. When sewage collects at a certain level below the inlet of the net bag, the sewage is sent to the secondary treatment tank from the overflow pipe that penetrates the primary treatment tank and reaches the secondary treatment tank. Like the primary treatment tank, air is sent from the blower installed outside the secondary treatment tank to the air ejection pipe provided at the bottom of the tank, and the air is ejected from the many air ejection holes of the air ejection pipe. The sewage is jetted into the sewage to stir the sewage, and the air is taken into the sewage surface from the air intake pipe provided in the tank from the floor, giving air to the aerobic microorganisms in the sewage and activating the activity of the aerobic microorganisms. . Further, an electric heater is provided in the wastewater in the secondary treatment tank to heat the temperature of the wastewater to the optimum temperature for the activity of aerobic microorganisms. Therefore, the activity of the aerobic microorganisms is further activated, and the sewage is decomposed into hydrogen, nitrogen, carbon dioxide and water, and completely decomposed into gas. This vaporized gas is exhausted from an exhaust pipe which is inhaled by an exhaust fan installed upright on the tank top plate.
In the secondary treatment tank thus treated, a fixed amount of sewage that has normally flown from the bulky substance separation tank is accumulated, and does not increase. Therefore, this mobile unit toilet does not need to be pumped or connected to sewer.

If the amount of dirty water changes for some reason, the heater, blower, and exhaust fan capacities are changed to change the heating temperature of the heater, the amount of air blown from the air discharge pipe,
The intake air amount of the exhaust fan can be changed to return to a steady state.

The roof of the mobile unit toilet is a rainwater receiving plate that is gently inclined toward the center to form a rainwater receiving plate. Since a hole is opened in the center of the roof, rainwater is collected when it rains. Drained down the hole. A rainwater storage chamber for collecting rainwater is provided on the ceiling below the hole and on the side wall of the toilet room, and the rainwater flowing in from the hole below is stored in the rainwater storage chamber and used as flush water. It Therefore, even if the mobile unit toilet of the present invention is temporarily installed in a place without water, it is possible to wash with water. If rainwater is insufficient, bring in water separately for storage. An overflow pipe will be installed above the rainwater storage chamber above the ceiling to drain excess rainwater. Also,
The stored rainwater in the rainwater storage room provided on the ceiling and the side walls acts as an insulator, so the heat of the midsummer sun is blocked and the flight room is kept cool. Furthermore, since the exhaust stack is inclined inward to cover the roof, it blocks the sunlight and softens the heat of midsummer.

Since the blower for supplying air to the air ejection pipe is laid in the stairs in front of the toilet entrance, the unit is compactly formed without taking up space.
