<p>PROBLEM TO BE SOLVED: To economically operate a reutilizing device and to obtain an inexpensive and compact device by constituting the device to enable to take out treated water for every use at respective stages different from at least two stages or more in water quality, in reutilization of the treated water after a purifying treatment of domestic waste water. SOLUTION: Waste water from a bathroom, etc., is collected into a waste water collection box 3 through a water discharge pipe 1 and also rainwater is fed through a rainwater pipe 2, and the waste water overflowed from the waste water collection box 3 is discharged to a sewer. A pump 4 is fitted in the waste water collection box 3, and the waste water is fed to purifying parts 6, 7 by its operation via an electromagnet 5 and also the waste water is purified in circulation between these purifying parts 6, 7. At this time, the purifying part 6 is preferably constituted of a biological filter bed, while the purifying part 7 is constituted of a ceramic filter bed. Also, the purifying part 6 is connected with a storage part 9 via a solenoid valve 8 and a purifying part 10 is formed in the storage part 9. Besides, a storage part 12 is connected with the storage part 9 via a solenoid valve 11, and a purifying part 13 is formed in the storage part 12.</p> |
