However, in such a conventional domestic wastewater treatment system, as described above, domestic wastewater containing garbage is passed through a pipe from a disposer disposed in a kitchen to a solid-liquid separator and a raw wastewater. After being treated by the garbage annihilator, it was discharged to the sewer as wastewater.
During the discharge, a large amount of tap water was required. For example, to process 160 kg / hour of garbage, about 20 kg
When liters / minute of tap water was required and used for 2 hours a day, as much as 2,400 liters of tap water was used. Therefore, the running cost of the wastewater treatment system was large.
