ABSTRACT:
A recovery apparatus comprising a running member which runs between a first position where the member is immersed in the liquid stored in a reserve tank and a second position where the member projects upwards from a surface level of the liquid, and a bucket which is secured to the running member and which scoops the floating matter floating at the surface level of the liquid, while moving from the first position to the second position. The bucket comprises a bucket body which has an opening for allowing the liquid containing the floating matter to flow in, and which gradually narrows downwards from the opening, partition plates which extend downwards from the opening and face each other and which block the floating matter flowing from the opening, and discharge ports which are made in the bucket body and open at a position lower than the opening.
