- drainage from the road surface flows into the maintenance tank 7 through the roadway guideway 120, the inflow section 30 and the inflow opening 40. Since the maintenance tank 7 and the treatment tank 9 communicate with each other at the lower part, the flow path 33 is filled with inflow water, and when the road surface drainage continues to flow into the maintenance tank 7, the water level rises, and the water in the treatment tank 9 rises.
- the drainage flowing from the bottom to the top passes through the treated material container 27 and is sequentially discharged from the discharge unit 31.
- the contaminants are removed by the treatment material 57 while the inflow water flowing into the maintenance tank 7 passes through the treatment material container 27 and rises in the treatment tank 9.
- the ring-shaped elastic water-stopping member 7 9 is in a state where the water-stopping projection 8 1 blocks the gap G, and the road surface drainage that has flowed into the treatment tank 9 through the communication portion 23 is stored through the lower mesh cloth 65.

- Pollutants that have accumulated on the road surface are sequentially carried away by rainwater. For example, if there is a rainfall of about 8 to 10 mm / h, most of the road surface sediment will be washed away in about 30 minutes. This flows into the maintenance tank 7 and the contaminants are removed in the treatment tank 9. If the rainfall continues after that, little or no pollutant will flow into the maintenance tank 7 even if it does.

- the cover plate When the opening 17 of the maintenance tank 7 and the opening 19 of the treatment tank 9 can be opened and closed by the cover plate 20, the cover plate is divided into two parts and both openings 19, 20 are opened and closed individually. It may be configured.
- the cover plate 20 When the cover plate 20 is provided so as to be openable and closable, when the road surface drainage is configured to flow into the maintenance tank 7, only the opening 19 of the treatment tank 9 is covered with the cover plate 20 as shown in Fig. 32. In some cases, it can be opened and closed. In this case, when the maintenance tank 7 is full of inflow water and the drainage cannot be filled, excess water is closed from the maintenance tank 7 as shown by the arrow in Fig. 32. It flows on the upper surface of the plate 20 and is discharged from the discharge unit 31. On the other hand, when the wastewater flows into the treatment tank 9, only the opening 17 of the maintenance tank 7 can be opened and closed by the cover plate 20, as shown in FIG.
- the maintenance tank 7 does not necessarily need to be filled with a suction pipe as long as it has an opening at the top and can remove sediment at the bottom.
- the bottom of the treatment tank 9 must be maintained. It is not necessary to use a downward slope toward the control tank.
- FIG 34, Figure 35, and Figure 36 to Figure 38 show a road surface wastewater treatment system 1 that can handle a large amount of wastewater to be treated. It has a treatment tank and one maintenance tank.
- FIGS. 34 and 35 two treatment tanks 9 are provided, and the lower portions of both are connected to the maintenance tank 7 via the communication part 23.
- the wastewater that has flowed into the maintenance tank 7 from the inflow section 30 flows into the processing tanks 9 and 9 through the communication section 23 as shown by the arrows in Fig. 34, and is contaminated by the processing material 57.
- the substance is removed and discharged from the discharge section 31 as shown in FIG.
- Figure 36 shows two treatment tanks 9 and 9 installed on both sides of the maintenance tank 7.
- two treatment tanks 9 and 9 are provided on one side of the maintenance tank 7, and the respective treatment tanks 9 and 9 are connected to the maintenance tank 7 via the communication part 23.
- Fig. 38 two treatment tanks 9, 9 are connected to a long communication section 1 38 extending from the maintenance tank 7 via short communication sections 1 39, 1 39, respectively.
- the tanks 9 and 9 are connected to the maintenance tank 7 via the communication part 23.
- the maintenance tank 7 and the treatment tank 9 do not need to be made of concrete, and both the maintenance tank 7 and the treatment tank 9 are made of resin or steel pipe, and their lower parts are connected by pipes. A communication part is formed. It is also possible to construct the pit with cast-in-place concrete.
- a sponge-shaped elastic ring member 140 is attached to the annular fixing portion 80 and the water stopping projection 8 as shown in FIG. It is preferable to intervene between them.
- FIG. 40 shows an example of a water blocking protrusion 81 made of sponge rubber and formed in a semicircular cross section.
- FIGS. 41 and 42 show another example of the inflow opening 40 provided in the cover plate 20.

- the inflow opening 40 is not closed by the cover plate 20, and the inflow opening 40 is shown in FIG. 42 in the lower part of the cover plate 20.
- the maintenance tank and the treatment tank are communicated at the lower part, and the treatment tank is provided with a treatment material for removing contaminants in the wastewater. Contaminants are removed while sewage from factories, drainage from fields, etc.) flow through the maintenance and treatment tanks. Therefore, the treatment load on the sewage treatment plant can be reduced, and environmental pollution is reduced.
- the opening of the maintenance tank and the opening of the treatment tank can be opened and closed with a cover plate, so when the maintenance tank is full of inflow water, the opening of the treatment tank is closed with the cover plate, and the road surface drainage is discharged to the drain. Can be bypassed. Since the capacity of the maintenance tank and the treatment tank is sufficient for the initial rainfall, the equipment can be made compact, the installation space can be reduced, and the construction cost can be reduced.
- the cover plate is provided so that the opening of both the maintenance tank and the treatment tank can be closed, so that it is possible to prevent the inflow water from stirring the inside of the tank and soaring the precipitate, and the precipitate flows out of the outlet. Can be prevented.
- the lower end of the discharge section is located below the lower end of the inflow section so that the treated water from which contaminants have been removed is naturally discharged from the discharge section, and does not require power such as a pump.
- processing material container can be taken in and out of the processing tank, cleaning and replacement of the processing material are easy.
- the present invention removes pollutants in wastewater from roads and the like and prevents the pollutants from being diffused into the environment, thereby reducing environmental pollution and reducing pollutants flowing into a sewage treatment plant. Therefore, the load on the processing bath can be reduced.
