<p>PROBLEM TO BE SOLVED: To provide a flush toilet capable of improving the quality of washing water given to a stool, the maintenance property, and environmental hygiene and the reliability. SOLUTION: Soil water from a stool 3 is purified and treated in water activating chambers 9, 10 forming a three-phase fluidized bed, this treated water is separated into sludge and liquid by the action of gravitational force in a separation chamber 12 for further purification and treatment, and this treated water is supplied to the stool 3 as washing water. On the other hand, the deposit deposited in the separation chamber 12 is transferred into a collection chamber 15 by deposit transfer devices 37 to 39 for collection and storage to remove sludge without requiring human labor, improve purification capability, and eliminate a necessity of scooping up sludge by stopping the purification and treatment of soil water. The collection and storage exceeding a predetermined amount in the collection chamber 15 are detected by a detection means 55 to inform the detection by means of the detection means 55 by an alarm lamp, and scooping up of deposit in the collection chamber 15 is done based on the information to prevent overflow of water to the outside from the collection chamber 15.</p> |
