The discharge groove 6 is usually 240 mm × 240 mm
U-shaped trough. The intake of the road surface drainage into the inflow path 14 which is a bypass from the discharge groove 6 is performed by providing a weir 9 at a position of the discharge groove 6 higher than the treatment tank 1 and opening the water to the discharge groove side wall above the weir 9. Take in through mouth 8. For example, we have an inflow port on the upstream side and a weir 9
And a branch socket having a branched flow path may be provided in the discharge groove 6. By the way, when a large amount of rain falls, the initial one of the road surface drainage contains a large amount of oil, earth and sand, and other SS, but until a certain period of time, these are discharged from the inflow passage 14 to the treatment tank. 1, and after a certain period of time, oil, earth and sand, SS, etc. have already flowed out and are no longer contained in road surface drainage. Therefore, the height of the weir 9 is set to a height at which all road surface drainage is blocked by the weir 9 and flows into the inflow passage 14 until the above-mentioned oil, earth and sand, SS, etc. are no longer contained, and more. After the elapse of the time, the height is set to a level at which the weir 9 overflows and flows directly into the discharge groove 6. Alternatively, an intake plate is provided in the discharge groove 6 instead of the weir 9, and an iron plate 10 provided with a plurality of holes 11 opened by, for example, punching on the surface of the groove bottom 7 of the discharge groove 6 above the intake basin.
That is, a punching plate is placed, and the road surface drainage is taken into the inflow path 14 using the holes 11 as the water ports 8. The punching plate is not limited to the one opened by punching, and may have a grating structure by casting, and the punching plate is also referred to as a punching plate in the present invention. The punching plate is dropped so as not to protrude upward from the bottom of the groove. A filtering material 73 may be appropriately disposed in the intake basin 71 to filter large foreign matters and to take in the road surface drainage into the inflow passage 14.

Since the road surface drainage is taken in from the plate 10 in which the hole 11 of the groove bottom 7 is punched in this way, if a large amount of road surface drainage is generated, a part of the road surface drainage fills the intake basin 71 and the punching plate , The water flows down the discharge groove 6 without being taken into the intake basin below. Further, the bottom of the intake basin 71 is connected to the inflow path 14. The amount of inflow into the intake basin 71 is adjusted by the arrangement of the holes 21, the diameter of the holes, and the bottom slope of the slope adjusting side groove 72 which is the inflow path 14 to the treatment tank 1. In the wastewater treatment facilities of FIGS. 1 to 3, the slope adjustment side groove 72 is not provided, and in the wastewater treatment facilities of FIGS. 4 to 6, the slope adjustment side groove 72 is provided.

The process of treating road surface wastewater will be described with reference to a road surface wastewater treatment facility shown in FIGS. In this road surface drainage treatment facility, along the slope of the slope 21, the road surface drain collected in the side gutter of the road flows down the drain 6 formed of a U-shaped groove laid from above to below the slope of the road side slope 21. . During the operation of the slope 21, the treatment tank 1 is disposed with its longitudinal direction arranged perpendicular to the drain groove 6. The treatment tank 1 has an inflow storage tank 2 on the drain groove 6 side. In this road surface drainage treatment facility, black water of road surface drainage containing earth and sand, dust, tire debris, oil, etc., flows down the drainage ditch 6 from the upstream as shown by the arrow, and is buried in the slope below the drainage ditch 6. Plate 1 on the taken intake basin 71
If the filter material 73 is installed in the intake basin properly, large impurities are removed. If the filter material 73 is not installed, the road surface drainage is left as it is. Flows through the inflow path 14 in the direction of the arrow and
3 rushes into the inflow storage tank 2 which is the first tank of the processing tank 1. Road surface drainage rushes into the inflow storage tank 2 and circulates in the inflow storage tank 2 because the partition wall 5 is located between the adjacent storage tank. Then, heavy sand partially precipitates during this circulation.

When the water level in the inflow storage tank 2 rises while circulating further, the road surface drainage in the inflow storage tank 2 flows in the direction of the arrow from the communication hole 17 provided in the partition wall 5, and flows into the next tank, the rectification storage tank. Flow into 3 Since the opening area of the communication hole 17 is narrowed to a certain size, the amount of inflowing water is limited, so that the water level of the inflow storage tank 2 rises to the height of the discharge port 13. On the other hand, the road surface drainage that has entered the rectification storage tank 3 has calmed down, so that sediment and dust settle at the bottom as indicated by the arrow, and the oil rises above the communication hole 17 as indicated by the arrow. The partition wall 5 between the storage tank and the outflow storage tank 4 is blocked by a portion above the communication hole 17 and does not flow into the outflow storage tank 4. Therefore, the road surface drainage excluding the oil floating above and the sand and the like settled at the bottom flows into the outflow storage tank 4 from the communication hole 17 as shown by the arrow.

In the outflow storage tank 4, the inflow road surface drainage becomes treated water from which SS of suspended matter such as earth and sand particles of 1 mm or less and carbon is precipitated and removed. The treated water rises in the outflow storage tank 4, flows into the drain pipe 20 from the treated water intake 18, flows in the direction of the arrow, and is discharged to the discharge groove 6 from the discharge port 20 facing the downstream discharge groove 6. You. A small hole 76 is opened in the upper part of the drainage pipe 20 in the outflow storage tank 4, and air flows therethrough. When the water level of the outflow storage tank 4 rises above the height of the bottom of the drainage pipe 20, the treated water is discharged from the drainage pipe 20. leak.
By the way, since the drainage pipe 20 is bent downward at the inlet 18 of the drainage pipe 20, the treated water flows through the drainage pipe 20 unless the height of the drainage pipe 20 is higher than the height of the drainage pipe 20 because the siphon principle works without the hole 76. Does not flow out of the discharge port 19.
