Abstract

The invention provides a biological permeation enhancing and flow reducing system which comprises a water intake apparatus, a biological permeation enhancing and flow reducing zone, a first overflow apparatus and a second overflow apparatus, wherein the water intake apparatus is used for collecting surface flow; the biological permeation enhancing and flow reducing zone is used for improving the permeability and the purification function of landscape green land soil to ensure permeation and purification of the surface flow; the first overflow apparatus is used for guiding and discharging surface flow beyond the flow interception capability of the biological permeation enhancing and flow reducing zone through a first water discharge pipe; the second overflow apparatus is used for overflowing surface flow beyond the flow interception capability of the biological permeation enhancing and flow reducing zone and the overflow capability of first overflow apparatus through a second water discharge pipe. Therefore, reformed urban landscape green land soil is utilized for surface flow management in the biological permeation enhancing and flow reducing zone, the permeation and the transpiration of the surface flow are improved, and the pollution caused by the surface flow is relieved when less surface flow is generated.

Description

technical field [0001] The invention belongs to the technical field of urban surface runoff pollution control, and in particular relates to a biological seepage enhancement and flow reduction 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 are...
