Abstract

Abstract

The infiltration characteristics in permeable brick pavement system (PBPS) of sponge city construction is its key factors, which influence the runoff producing time and the removal of heavy metals from runoff. Through the seepage test, the soil-water characteristic curves of PBPS soil layers were constructed, and then the infiltration model and the mathematical model for runoff heavy metal pollutant migration of PBPS was established. Finally, the effect of leveling layer soil particle size and base to cushion layer thickness ratio on the runoff producing time and the removal of heavy metals from runoff were illustrated. The results showed that with comprehensive consideration of the PBPS's ability in delaying runoff generation time and removal of heavy metal pollutants, medium sand was the best choice for leveling layer soil; according to the concentration of heavy metal pollutants in the effluent of the structure layer, when the ratio of base to cushion layer thickness ratio was 15∶4, PBPS had the highest adsorption efficiency and good effect on removing heavy metal pollutants in runoff.
