Abstract

The highway sponge-type composite side ditch carbon neutralization system of the present invention includes three units, i.e., a silt pre-sedimentation channel, a filtering and oil-absorbing channel and an ecologic purification channel which are connected horizontally and successively. These three units work together to jointly complete the low-impact development functions of runoff collection, guide and drainage, purification and utilization, carbon emission is reduced by adopting various technical measures, the carbon sink effect is improved, and the full-life-cycle carbon neutralization effect from raw material production, construction to operation can be realized.
