も考えられる。2. Description of the Related Art Conventionally, the scum skimmer of the scum collecting device itself cannot follow the fluctuation of the water level. Therefore, even if the scum skimmer is tilted at the same angle, the amount of water flowing into the scum skimmer is high when the water level is high. On the other hand, when the water level is too low, on the other hand, there is a problem that the amount of water flowing into the scum skimmer is small and the scum cannot be removed sufficiently. In order to deal with this, a method of adjusting the amount of water flowing into the scum skimmer by providing a floating streak having a constant water depth with the water surface is also conceivable.

水面上のスカムを効率よく流入させる。According to this embodiment, first, the gate opening / closing mechanism is operated to push down the flexible claw 2 below the surface of the water via the link 8. As a result, a water flow that tends to flow into the pipe scum skimmer 7 is generated, and the water flow causes the floating claw 4 to be pressed against the upstream surface 3 a of the baffle plate 3. That is, the floating deck 4 is always floating at a predetermined position below the surface of the water by the float 5, but when the flexible deck 2 is pushed down below the surface of the water, the floating deck 4 is blocked by the generated water flow. 3 is pressed against the surface 3a on the upstream side of 3 to be in close contact with the surface 3a, so that the treated water is prevented from short-passing from the gap between the baffle plate 3 and the floating baffle 4, and the scum on the water surface is efficiently supplied to the pipe scum skimmer 7. Inflow.

されて処理される。During this time, the float 5 keeps a predetermined position below the surface of the water by the float 5, that is, the position of the upper end of the float 4 at a constant water level. The amount of treated water flowing into the inlet of the scum skimmer 7 is always kept constant. And the scum and treated water that passed through the floating Zeki 4 are as described above.
After overflowing the upper space of the floating deck 4 and the inflow port 3b of the baffle plate 3, it overflows the upper space of the flexible deck 2 pushed down below the water surface and flows into the pipe scum skimmer 7.
It is collected in a scum pit, separated by a scum separation device, etc. and processed.

流入させて除去することができる。A mechanism for allowing the coarse scum to flow into the pipe scum skimmer 7 together with the treated water will be described by taking a manual gate opening / closing mechanism shown in FIG. 3 as an example. In this gate opening / closing mechanism, an operating lever 9 is attached to the link 8 via a transmission mechanism 8a, and a worker tilts the operating lever 9 to
It has a structure in which the flexible claw 2 is pushed down. by the way,
A float pressing mechanism composed of an operating rod 10 for pressing the float 5 is connected to the transmission mechanism 11 of the gate opening / closing mechanism so that the coarse scum that cannot pass through the floating shaft 4 can flow into the pipe scum skimmer 7 together with the treated water. That is, when the coarse scum stays on the upstream side of the floating deck 4, the worker tilts the operating lever 9 more than usual to push down the flexible deck 2 and hold down the float 5 with the operating rod 10. By pushing down the floating roof 4, the distance between the water surface and the upper end of the floating roof 4,
That is, the water depth at the upper end of the floating deck 4 is increased, and the coarse scum staying on the upstream side of the floating deck 4 is treated with the treated water, and the upper space of the floating deck 4 and the inflow port 3b of the baffle plate 3 are removed. After the overflow, the upper space of the flexible claw 2 pushed down below the water surface can be overflowed and flowed into the pipe scum skimmer 7 for removal.
