Problems solved by technology

Most of the fillers for domestic rainwater management measures directly apply foreign achievements, but due to the differences in various conditions such as meteorology, soil, runoff, and materials at home and abroad, copying foreign achievements will inevitably reduce the application effect of the technology

Abstract

The invention discloses a filling material for ecological storage-detention and purification measures of urban road rainwater. The filling material consists of the following components: sandy loam, coarse sand, vermiculite, perlite and turfy soil. The filling material can achieve relatively good water-permeability, water-retention and water-purification effects on the road rainwater, is beneficial for the growth of plants, is low in cost and relatively high in localization degree, is easy to obtain, and is relatively high in comprehensive benefit. The filling material disclosed by the invention can be used for providing the basis for filling material selection of domestic road rainwater management measures, and has important significance of increasing the water quantity and water quality treatment effects of source road rainwater management measures and promoting the application of a road rainwater management technology.

Description

technical field [0001] The invention relates to a filler for urban road rainwater ecological retention and purification measures. Background technique [0002] With the increase of urban road hardening area, the increase of rainfall runoff (waterlogging) and the deterioration of water quality (non-point source pollution) have become increasingly prominent. It is widely used in cities all over the world. The rainwater management measures for low-impact development, such as bioretention tanks and grass-planting ditches, which focus on road rainwater absorption, store and purify rainwater through the physical, chemical, and biological interactions between plants-fillers-microorganisms. It plays an important role in promoting plant growth, cultivating microorganisms, providing storage space for runoff, and exerting the adsorption and filtration effect on pollutants. [0003] At present, foreign fillers mostly recommend mixtures with good permeability, soil as the base, and a c...
