Abstract

The invention discloses a road surface runoff purification system. A water-permeable asphalt road surface is paved on a water-impermeable road surface layer; the upper end of a side slope pebble water-permeable layer is connected with the water-permeable asphalt road surface; a first gravel slightly water-permeable transition layer is paved above and a second gravel slightly water-permeable transition layer is paved below the side slope pebble water-permeable layer; the second gravel slightly water-permeable transition layer is paved on a water-impermeable clay layer; a planting soil layer added with an active adsorbing substance is paved on the first gravel slightly water-permeable transition layer; the side slope pebble water-permeable layer is connected with a drainage ditch through a second drainage pipe and a water-permeable cofferdam; the drainage ditch is made of a water-impermeable material and is connected with a ditch wetland through a third drainage pipe; and the water outlet end of the ditch wetland is provided with a fourth drainage pipe. The road surface runoff purification system can collect and preliminarily purify freeway road surface runoff and perform secondary deep purification on the road surface runoff through the ditch wetland.

Description

technical field [0001] The invention relates to a deep purification system for road surface runoff in a section of water area which has higher requirements on water quality, in particular to a road surface runoff purification system. Background technique [0002] At present, there is no system specially designed for the deep purification of road surface runoff in water areas with high water quality requirements, but the deep purification of road surface runoff in these road sections is of great significance to the protection of the local water environment. At present, the purification of road surface runoff is limited to the initial simple treatment level, thus making highway road surface runoff a potential hidden danger of water environment pollution. Road surface runoff often causes pollution to the local water environment that is difficult to repair due to incomplete purification, especially the incomplete degradation of some dissolved toxic and harmful substances. It wi...
