Abstract

The invention provides an urban surface runoff filtration system. The system comprises: a deposition chamber used for removing large-granule pollutants in surface runoff through deposition; a filtration chamber used for removing small-granule pollutants in the surface runoff through filtering adsorption of the surface runoff; and a water drainage chamber used for draining the filtered surface runoff through a water drainage pipe. The filtration system is applied in land space-limited urban roads and parking lots in a buried form, can efficiently remove pollutant granules in the surface runoff without influencing the surface functions, allows the removal rate of the pollutant granules to reach above 90%, and reduces the influences of the urban road and parking lot surface runoff pollution on the quality of receiving water.

Description

technical field [0001] The invention belongs to the technical field of urban surface runoff pollution control, in particular to an urban surface runoff filtering system. Background technique [0002] Urban surface runoff pollution has caused serious water environment deterioration and water ecological crisis in many parts of the world. With the acceleration of urbanization in my country, the expansion of urban scale, the change of land use / cover and the emergence of a large number of impermeable surfaces have significantly changed the regional hydrological process. pollution. [0003] Urban surface runoff contains suspended particulates, nutrients, heavy metals, and toxic organic pollutants from various human activities. Urban surface runoff is one of the important transmission routes for non-point source pollutants to enter receiving water bodies. Among them, building roofs, roads and parking lots are the main impermeable surfaces in urban areas, and are the main source ar...
