ABSTRACT:
The present invention is a scum-treating apparatus installed in the disposal pond for removing the scum floating on the surface of the water with the movement of the flights in the disposal pond as the motive power to purify the water. The trough is fixed and the damming-up device is provided in front of the trough to move up and down the damming-up device by being interlocked with the flights. In particular, the interlocking is provided by a plurality of projecting portions and dented portions between the projecting portions at a pointed end thereof, so that the large scum are flowed into the trough when the flights correspond to the respective projecting portions while the float is slightly risen up under the surface of the water when the flights correspond to the dented portions to collect the far scum toward the trough. Thus, both the large scums and the small scums can be effectively introduced into the trough.
