複数設置して対応する。BACKGROUND OF THE INVENTION The present invention relates to an upward flow type inclined plate device in a wastewater treatment device. The details of the invention are shown in FIG. The upward flow type inclined plate device includes a sedimentation basin (7), an inclined plate (2), a supernatant water trough (3), a water collecting nozzle (4), a water nozzle (5), a drain valve (8), a water supply valve ( 9). As shown in FIG. 1, the inclined plate (2) is installed in the sedimentation basin (7). The upper part of the inclined plate (2) is installed above the water surface L-1. There is a supernatant water trough (3) for collecting the treated water of the inclined plate (2). At this time, the water level L-3 in the supernatant water trough (3) is lower than the water level L-1. The supernatant water trough (3) has a water collecting nozzle (4). The mounting position of the water collecting nozzle (4) to the supernatant water trough (3) is horizontal, bottom, and both side surfaces.
Also, there are upper and lower cases of the mounting level of L-3. Raw water flows in from the lower part of the inclined plate (2). The solids in the raw water settle and settle on the surface of the inclined plate (2).
Treated water flows out from the collecting nozzle (4) installed in the supernatant water trough (3) to the supernatant water trough (3), and the sedimentation basin (7)
Spills out. When the drain valve (8) is opened, the level L-2 drops below the level L-1, and the outlet of the treated water switches from the supernatant water trough (3) to the drain trough (1). The amount of drain water to the drain trough (1) is larger than the amount of water passing through the collecting nozzle (4). Therefore, the flow velocity between the inclined plates (2) suddenly increases, and the solid matter attached to the inclined plates (2) is separated. As a result, the solid matter adhering to the inclined plate (2) is removed to the drain trough (1) and the bottom of the sedimentation basin (7). The floating matter (6) floating between the inclined plates (2) can be discharged and removed together with the treated water to the drain trough (1) by opening the drain valve (8) installed in the drain trough (1). . At this time, drainage trough (1)
The upper surface of the overflow section is below the upper part of the inclined plate (2). The type of drain valve (8) only needs to be able to open and close the outflow of treated water.
A gate or a siphon device may be used. Drainage trough (1) The amount of drainage is determined by the depth above the overflow and the level L-1. Usually, the amount of drainage to the drainage trough (1) is called overflow load. The amount of water required to remove solids depends on the type of wastewater. When the type of drainage is sewage, the required overflow load is 500 m 3 / m day or more. By opening the water supply valve (9) and injecting pressure water from the water nozzle (4) in the direction of the drain trough (1), surface water between the inclined plates (2) flows into the drain trough (1). And promotes the effect that the suspended matter (6) flows out to the drainage trough (1). Water is supplied to the water nozzle (5) by opening and closing a water supply valve (9). The opening and closing of the water supply valve is linked to the opening and closing of the drain valve (8). Incidentally, the treated water trough (3) and the drainage trough (1) do not necessarily need to be integrated with the sedimentation basin (7). In addition, drainage trough (1)
Is located above the inclined plate (2) when the water surface L-1 is located above the inclined plate (2). The upper position of the drainage trough (1) may be variable. When the pond width of the sedimentation basin (7) is wide, the supernatant water trough (3) above the inclined plate (2) and the drainage trough (1) are alternately provided in a plurality to correspond.

In the prior art, since there is no drainage trough (1), to remove suspended matter (6) floating between the inclined plates (2) and solid matter attached to the inclined plates (2), a sedimentation tank (7) is used. Must be emptied, maintenance is difficult, and it takes a lot of time.

According to the present invention, the drainage trough (1) and the drainage valve (8) are installed separately from the treated water trough (3), and the drainage valve (8) is opened at the outflow destination of the treated water trough (3). It is to switch from 3) to drainage trough (1). When the drain valve (8) is opened, the treated water flows out to the drain trough (1). At this time, the amount of treated water increases. As a result, the flow rate of the treated water passing between the inclined plates (2) can be rapidly increased. By suddenly increasing the flow velocity between the inclined plates (2), solid matter adhering to the inclined plates (2) is separated from the inclined plates (2), and the sludge attached to the inclined plates (2) can be removed. The surface water between the inclined plates (2) is drained trough (1).
Is drawn to. As a result, the suspended matter (6) can be discharged and removed to the drain trough (1). In addition, by installing the water nozzle (5), the suspended matter (6) can be crushed, and the outflow effect of the suspended matter (6) can be promoted.
