Abstract

A raw sewage disposal apparatus, such as a portable toilet. The apparatus has a vessel with a first introduction pipe for feeding raw sewage into the vessel. The vessel is externally heated and contains heat-holding bodies and an agitator so that the sewage can be heated to evaporate liquid therefrom while being agitated to break down nonevaporable substances into powder. Air is circulated through the vessel to remove the vapor and later the powder therefrom. A deodorizing means including a catalyst, and a preheater for preheating the catalyst, are provided to treat the vapor to make it substantially odorless. A dust collector is provided to collect the powder. The dust collector can be heated, if necessary, to evaporate liquid present therein. A liquid level detector can be provided on the vessel to indicate when the vessel contains a large amount of raw sewage.
