Provided are a circulation type flush toilet system without water supply, which has excellent purification capability of waste water discharged from the toilet, and biodegrades the waste water to gain reusable water, and a container toilet accommodating the system. The system comprises: a raw water tank (1) which purifies the waste water discharged from the toilet in the flush toilet (R1); a pretreatment unit (2) which purifies the treated water purified in the raw water tank; a post-treatment unit (3) which purifies the treated water purified in the pretreatment unit; and a water supply unit (4) which provides the treated water purified in the post-treatment unit to the flush toilet for cleaning the toilet. The pretreatment unit (2) comprises an anaerobic tank and an aerobic tank, the aerobic tank includes a Cryptomeria japonica chip (22E), of which surface area having a microorganism and a nutritional supplement fixed thereto is 10 m^2/gr, as a contact media (22A) with which the treated water contacts, a negative electrode (22B) and positive electrode (22C) as a means of applying a direct current 2-30 V, a voltage in a range of 1-10 A, and a current to the treated water; and a far infrared radiation ore (22D) as a means of irradiating the Cryptomeria japonica chip and the pre-treated water with a far infrared radiation having a wavelength of 4-20 μm. |
