Abstract
Abstract A compost-type toilet which includes: a solid-liquid separating means which also serves as a means for transferring the solid component of excrement mounted below the opening of a bowl; a means for treating the liquid component of excrement provided beneath the solid-liquid separating means. The liquid component treating means contains various kinds of adsorbent materials capable of adsorbing the liquid component separated by the above mentioned solid-liquid separating means and the inner structure is so constructed as to enhance the air ventilation to vaporize or volatilize the liquid component adsorbed with the adsorbent materials; a means for treating the solid component of excrement is provided in a position adjacent to the solid-liquid separating means in the transferring direction to the solid component separated by the above mentioned solid-liquid separating means. The means for treating the solid component is a treatment chamber comprising a supply device for an auxiliary agent for treatment of the solid component mounted in the upper part thereof and a stirring apparatus contained in the lower part; and, a storing part for the treated solid component and excessive liquid component provided by communicating the said means for treating a solid component and a liquid component therewith, whereby the above mentioned means and devices are formed to one unit.
