Abstract

PURPOSE:To keep treatment capacity to a predetermined degree over a long time, by fixing a large number of discs to the rotary shaft arranged in a tank so as to leave predetermined gaps therebetween and loosely insert rake plates of first and second rakes in said gaps. CONSTITUTION:Raw water flowed into a tank 1 from an inflow port 4 is impinged to the closure plate 17 and rake plate 16 of a first rake 14 and discs 10, and te greater part of raw water is flowed to the same direction as the rotary direction of the discs 10 by the rotation of the discs 10 to reach a second rake 15 and filtered between the discs 10 and rake plates 19. The dust clogged in the gaps between the discs 10 is forcibly scraped off by the relative motion of the rake plates 19 to the discs 10 and forcibly discharged from a dust discharge port 5 by a water stream. The filtered water passed between the discs 10 and the rake plates 16, 19 of the first and second rakes 14, 15 is discharged from a discahrge port 6 and used as service water.

This invention is as described above, and a large number of discs are fixed to a rotating shaft installed in a tank with a predetermined gap between them, and each rake plate of the eleventh and second rakes is loosely inserted into this gap. Clean water is obtained by filtration between the disc and each rake plate, and the dirt stuck in the gaps between the discs is constantly forcibly scraped off by the rake plate of the second rake, making it easy to clean. There is no clogging, and the processing capacity can be maintained at a predetermined level for a long time. In addition, since the filtration mechanism is simply composed of a combination of plate bodies, the inside of the tank is simple, there are few machined parts, the device can be provided at a low cost, and maintenance is easy.
