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. A second introduction pipe is provided to circulate air through the vessel to remove the vapor and later the power 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 third introduction pipe is provided for supplying fresh air to the preheater. A dust collector is provided to collect the powder.
