The strainer 3 and the filter cloth 4 are rotated through the rotary shaft 2 and the rotary disk 21, and the filter cloth 4 is rotated by centrifugal force.
With the water adhered to the inner surface of the strainer-3,
More dirty water is sprayed on the inner surface of the filter cloth 4. The injected sewage is forcibly permeated from the inner surface of the filter cloth 4 to the outside of the strainer-3 by the centrifugal force, so that the filter is effectively filtered. The filtered treated water is collected in the water collecting part 11 and drawn out from the water intake 12. If diatomaceous earth is mixed in the wastewater and the inner surface of the filter cloth 4 is precoated, the filtering effect can be further enhanced. On the other hand, the sludge adhering to the inner surface of the filter cloth 4 moves to the lower end side along the inner surface of the filter cloth 4 by the centrifugal force, and moves from the lower end opening to the sludge chamber 13
Fall inside. The sludge that has fallen is scraped by the scraping plate 14, and is further pressure-fed to the sludge discharge chamber 16 by the ogas cru 15 and discharged from there.

つ交互に繰り返して運転を行う。(2) Washing process While the operation is continued, the sludge which cannot be discharged completely loses its water content and adheres to the inner surface of the filter cloth 4. Therefore, the cleaning of the filter cloth 4 is required. In this case, the rotation of the strainer-3 and the filter cloth 4 is stopped, and the filter cloth 4 is separated from the inner surface of the strainer-3 as shown in FIG. Cleaning water is sprayed from the pipe 5 onto the inner surface of the filter cloth 4. Since the inner space of the filter cloth 4 becomes narrower and the entire inner surface of the filter cloth 4 becomes closer to the opening of the water supply pipe 5, the sprayed cleaning water collides strongly with the inner surface of the filter cloth 4, and The sludge that has been agitated by and adhered to the inner surface of the filter cloth 4 can be effectively washed off. In addition, the sludge that has not been washed off at this time is sufficiently softened by the wash water, so that it can be easily removed by centrifugal force when the filtration operation is performed again. Instead of washing water, high pressure air is jetted from the water collection pipe 5 to the inner surface of the filter cloth 4,
It is also possible to blow off the sludge that adheres. After the cleaning process is completed, the strainer 3 and the filtering cloth 4 are rotated again to perform the filtering process, and the filtering process and the cleaning process are alternately repeated for a predetermined time to perform the operation.
