The trough 7 has a U-shaped trough shape, and one side of the trough 7 has a scum attracting side lower than the water surface 5. Flange 8 is attached to both ends of the trough 7, and the flange 8 is bolted to a flange 11 of a communication trough 10 inserted and fixed to a pond side wall 9.

The scum water from the adjacent trough flows into the trough 7, and the scum water flows in one direction. Therefore, the trough 7 is slightly inclined in one direction. The displacement member 13 is attached to the attracting side of the trough 7 by fasteners (bolt nuts) 14 ... This displacement member 13
Is made of rubber or a similar elastically deformable resin or the like. In this embodiment, the displacement member 13 is
It is made of rubber and is a thin strip material.

A dam member 15 made of stainless steel or the like is detachably attached to the upper end, which is the tip of the displacement member 13, by a fastener 14, and notches 16 ... Are formed on the upper side thereof as shown in FIG. Has been done. Both the displacement member 13 and the dam member 15 can be displaced back and forth, and the displacement member 1 is provided on the trough 7 side corresponding to both sides of the displacement member 13.
Seal side plates 17 that slide and exhibit a sealing effect are arranged in a laterally opposed manner.
