<p>PROBLEM TO BE SOLVED: To provide a simple toilet which adopts an automatic and circulative decomposing-and-recycling method by biological treatment and filtration and can cut maintenance such as water feeding, disposal and the like by making use of natural energy. SOLUTION: Human waste is separated into solid and liquid by a solid-liquid separating means 2. The solid is decomposed in a solid treating tank 4. The liquid is clarified to get colorless and odorless regenerated water extremely close to primary water by repeating the clarification executed by circulating it through filtrating containers 7-14 equipped with more than one kind of natural filter medium and filters. Water used for washing hands flows through a perfectly independent regenerating-and-circulating route and becomes germ-free, odorless and colorless regenerated water by receiving the clarification conducted by complex bacteria combined with aerobic microorganisms under aeration to be used again for washing hands.</p> |
