Claims

[Scope of utility model registration request]

Flush toilet sewage is separated into floating matter, separated water, and precipitated solids, and a sewage sedimentation separation chamber serves as a primary treatment section that performs anaerobic treatment, and the primary treated water from the sewage sedimentation separation chamber is further converted into supernatant water. The system consists of a settling chamber that separates the precipitated sludge, and a contact aeration chamber that performs aerobic treatment through the action of aerobic microorganisms that adhere to the surface of the contact material by aerating the primary treated water with air supplied from a blower. In a septic tank equipped with a secondary treatment section, a tertiary treatment section consisting of a filtration chamber, a purification chamber, and a water storage chamber is connected to the secondary treatment section, and the filtration chamber has a tertiary treatment section for removing suspended substances in the secondary treatment water. A filter medium layer arranged in layers,
It consists of a conduit that guides the secondary treated water from the bottom of the chamber to the top through a filter layer, and the purification chamber is a filter that deodorizes and decolorizes the treated water from the filtration chamber in the process of flowing countercurrently from the top to the bottom. and a treated water return pipe consisting of a pump and a return pipe for returning the treated water to the upper part of the purification chamber in order to repurify the water in the water storage chamber which receives the treated water flowing in from near the bottom of the purification chamber. Furthermore, a circulation pipe with a pump was connected between the water storage room of the tertiary treatment section and the low tank of the flush toilet, and the supernatant water was circulated back to the low tank for reuse for flushing. A circulation type septic tank with this as an i feature.
