Detailed Description
The present utility model will be described in further detail by way of examples with reference to the accompanying drawings, which are illustrative of the present utility model and not limited to the following examples.
The embodiment is a rain and sewage diversion system for outdoor surface source pollution, which is arranged outside an outdoor surface source pollution area 11 and is used for respectively treating sewage in the outdoor surface source pollution area 11 and rainwater outside the outdoor surface source pollution area 11 during rainfall.
In this embodiment, a sewage ditch 1 is surrounded and arranged outside a non-point source pollution area 11, a ditch grid cover plate 3 is paved on the surface of the sewage ditch 1, a sewage drain pipe 4 is connected to the bottom of the sewage ditch 1, the end part of the sewage drain pipe 4 is connected in a sewage well 5 outside the non-point source pollution area 11, the inlet end of the sewage well 5 is connected with the sewage drain pipe 4, the outlet end of the sewage well 5 is connected with a municipal sewage pipe 6, and the installation position of the municipal sewage pipe 6 on the sewage well 5 is lower than that of the sewage drain pipe 4. In this embodiment, the top of the bilge well 5 extends to the ground and the bilge well cover 7 is paved on the top of the bilge well 5. Thus, when more sewage is accumulated in the non-point source pollution area 11 and flows out of the non-point source pollution area 11 under rainfall or other conditions, the sewage can preferentially flow into the sewage ditch 1 surrounding the outer side of the non-point source pollution area 11, the ditch grating cover plate 3 arranged at the top of the sewage ditch 1 has a good filtering effect on the sewage flowing into the sewage ditch 1, and impurities can be effectively prevented from entering the sewage ditch 1 along with the sewage to cause sewage drainage ditch blockage. The sewage well lid 7 arranged at the top of the sewage well 5 can effectively prevent personnel from falling into the sewage well 5, and meanwhile, personnel can conveniently enter the sewage well 5 to overhaul the sewage drain pipe 4 and the municipal sewage pipe 6 by opening the sewage well lid 7. The sewage drain pipe 4 is installed at a position higher than the municipal sewage pipe 6 at the sewage well 5, so that sewage flowing into the sewage well 5 from the sewage drain pipe 4 flows into the municipal sewage pipe 6.
In this embodiment, the outside of the sewage ditch 1 is surrounded and provided with a rainwater ditch 2, a ditch grid cover plate 3 is paved on the surface of the rainwater ditch 2, a rainwater drain pipe 12 is connected to the bottom of the rainwater ditch 2, the end part of the rainwater drain pipe 12 is connected in a rainwater well 8 outside a non-point source pollution area 11, the inlet end of the rainwater well 8 is connected with the rainwater drain pipe 12, the outlet end of the rainwater well 8 is connected with a municipal rainwater pipe 9, and the installation position of the municipal rainwater pipe 9 on the rainwater well 8 is rained at the installation position of the rainwater drain pipe 12. In this embodiment, the top of the catch basin 8 extends to the ground, and a catch basin cover 10 is paved on the top of the catch basin 8. Thus, when more rainwater is accumulated outside the area 11 with surface source pollution and flows into the area 11 with surface source pollution under rainfall or other conditions, the rainwater can flow into the rainwater ditch 2 surrounding the outer side of the sewage ditch 1 preferentially, the ditch grille cover plate 3 arranged at the top of the rainwater ditch 2 has good filtering effect on the rainwater flowing into the rainwater ditch 2, and impurities can be effectively prevented from entering the rainwater ditch 2 along with the rainwater to cause rainwater drainage ditch blockage. The rainwater well lid 10 that sets up at rainwater well 8 top can effectively avoid personnel to fall to rainwater well 8 in, makes things convenient for personnel to enter into rainwater well 8 through opening rainwater well lid 10 simultaneously and overhauls rainwater drain pipe 12 and municipal rainwater pipe 9. The installation position of the rainwater drain pipe 12 on the rainwater well 8 is higher than the installation position of the municipal rainwater pipe 9 on the rainwater well 8, so that rainwater flowing into the rainwater well 8 from the rainwater drain pipe 12 can flow into the municipal rainwater pipe 9.
The foregoing is only a preferred embodiment of the present utility model, but the scope of the present utility model is not limited thereto, and any person skilled in the art, who is within the scope of the present utility model, should make equivalent substitutions or modifications according to the technical scheme of the present utility model and the inventive concept thereof, and should be covered by the scope of the present utility model.
