Be incinerated. The filtered urine from which impurities have been removed is introduced into the ammonia diffusion tower 12, and the water vapor 3 diffuses the ammonia in the urine. The stripping tower 12 is of a scrubber type or multi-stage contact type in which the urine is sprayed from the top of the tower, and it is advisable to contact steam with alternating current. The treated water from which the ammonia has been removed is introduced into the UASB reaction tank 13 (self-granulating type upflow anaerobic filter bed) under anaerobic conditions in an upward flow, and organic matter in the treated water is converted into methane by methane fermentation. Decomposed into carbon dioxide gas. Excess sludge generated from the UASB reaction tank 13 is sent to the incineration step 2 from the delivery system 18 and is incinerated as it is or after dehydration.

4. For example, post-treatment may be performed by a denitrification activated sludge method or the like. Further, if there is another organic wastewater treatment facility such as sewage in the facility, the treatment process may be performed. In the above, the ammonia 15 diffused from the ammonia stripping tower 12 can be introduced into the incineration process 2 in a gas state and burned. In addition, the injected ammonia 15 can be injected into the waste gas to reduce the decomposed oxide nitrogen in the waste gas into nitrogen gas (denitrification) and release the incineration process waste gas as the denitration waste gas.

In the final disposal site leachate 20, sedimentation and impurities are removed in a pretreatment step 21 such as sedimentation, screen and filtration, and the impurities are sent from the delivery system 18 to the incineration step 2 and incinerated.
The leachate is sent to the evaporation step 22 where it is evaporated, condensed and solidified by the steam 3 from the boiler. The evaporated water is condensed and introduced into the secondary biological treatment step 14 for human waste and septic tank sludge to be treated. As the heat source in the evaporation step 22, electric power from the power generation step 4 may be used instead of steam. Further, the solid matter (crystal matter, etc.) 24 from the evaporation step 22 is carried out to the final disposal site.
