To do. In this case, the purified water can be subjected to a treatment for solid-liquid separation after biological treatment, and the cleaning water circulation supply pump to the toilet can be configured to operate by using the solar cell as a power source.

Further, the toilet equipment of the present invention comprises a flush toilet body, a septic tank for purifying the waste water from the toilet body,
A purified water recovery pump that collects the purified water treated in the septic tank to circulate and supply it to the toilet body, and a water supply that is provided between the purified water recovery pump and the toilet body to send the purified water to the toilet body. A pressurizing type water supply device provided with a pump is provided, and a pipe for using the groundwater pumped up by the groundwater pump for washing water is connected to the toilet body.

In this case, the purified water recovery pump and the water supply pump may be included in a drive system using a solar cell as a power source.

[0011]

[Operation] By purifying the sewage containing the wash water of the toilet, and by utilizing the ground water and / or the purified water as the wash water, the water purified by the septic tank is circulated to wash the toilet body and the filth. It can be used for discharge and does not require external water and sewage piping, so it can discharge and purify sewage independently and can be installed on the site without water and sewage facilities. Can be used effectively.

[0012] The purified water is biologically treated and solid-liquid separated, so that the treated water from which solids are surely removed is used as toilet wash water.

Further, the circulation supply pump for flush water to the toilet bowl converts the solar energy obtained by the solar cell as an electric power source and stores it in a storage battery or the like to use the electric power, so that it is necessary to supply the electric power from the outside. Therefore, it is possible to apply it without selecting the conditions of the installation site as in the case of treating the wash water.
