In general, the sewage discharged from outdoor toilets or domestic sewage not only contains a large amount of nitrogen (N) and phosphorus (P), which causes eutrophication, but also generates a bad smell.

Nitrogen (N) and phosphorus (P) contained in sewage act as nutrients for protein and nucleic acid synthesis for the activity and proliferation of microorganisms, and the surplus is removed or discharged to become a major cause of water pollution such as eutrophication.

Recently, biological treatment processes or chemical treatment devices and techniques have been developed to remove nitrogen (N), phosphorus (P) and odors contained in sewage, but most toilets or sewage treatment facilities are inconvenient to maintain and burden on environmental impact. It is difficult to apply the chemical treatment process.

As an example, there is a natural fermentation type mobile or fixed toilet or a potent toilet equipped with a bubble generator as a means to reduce the odor inside the toilet, but the odor is severe because manure is accumulated and stored in a storage tank. It is unsanitary due to the occurrence of pests, and the inconvenience of having to collect manure and sewage on a regular basis and as a secondary environmental pollution source in the collected manure and sewage disposal are virtually impossible to operate. Therefore, publicly installed parks, walkways, riverside paths, and hiking trails have had many difficulties in efficient maintenance.
