Abstract
PURPOSE: To prevent sticking of inclusions to pumps and transfer pipes by separating the inclusions such as refuse larger than certain sizes in the outflow side zone of a tank, circulatively flowing the inclusions remained in the tank together with the sewage in the tank and energizing in that direction.
CONSTITUTION: The sewage flowing in through an inflow pipe 1 passes through a coarse-meshed screen 3 and fine-meshed screen 4 in a flow passage 2, and enters an inclusion removing tank 5. At this time, large refuse such as paper scraps in the sewage is separated by said screens, and pebbles, sand and the like remain in a sand sedimentation 6. Inclusions 7 such as refuse, dirt and the like having passed through said screens or overflowed therefrom enter the tank 5 together with the sewage, where they are circulatively flowed in the arrow direction by the air blowing upward through the holes 9 of an air diffusion cylinder 8 provided in the bottom part on the outflow side of said tank. For example, the screen 3 of about 5cm width and the screen 4 of about 2cm width are used.
