[0013] According to the sewage treatment apparatus configured as described above, the inflowing sewage is purified in the active water chamber forming the three-phase fluidized bed, and the treated water is separated in the separation chamber.
While the sludge and the liquid are separated by the action of gravity and further purified, the sediment precipitated in the separation chamber is transferred to the storage chamber by the sediment transfer device and stored. For this reason, the sludge is removed without manual intervention, thereby improving the purification ability, and eliminating the need to stop the purification process of the wastewater one by one and scoop up the sludge. The detection means detects the storage of the storage chamber by a predetermined amount or more, and the warning light notifies the detection by the detection means. For this reason, by pumping the storage room using this notification as a guide, overflow from the storage room to the outside is prevented. In this sewage treatment apparatus, a flush toilet is configured by using a toilet as a supply source of incoming sewage and supplying treated water from the separation chamber to the toilet.
