摘要: Rainfall runoff impacted by anthropogenic activities transports significant quantities of particulate, aqueous, and complexed constituents. These diffuse, unsteady, stochastic event-based loadings are unique challenges for water quality (concentration, mass) quantity control (volume, peak flow). While many infiltration/exfiltration structural best management practices (BMPs) or low impact development implemented, few in situ data sets examined actual events temporal-based BMP behavior, part due to costs such examinations. Fewer studies provided a statistical mechanistic interpretation performance. The design, quality, functions partial exfiltration reactor (PER) utilizing Fe-coated sand is specifically across three type rainfall-runoff over 10-month period. Reduction total concentrations metals (Zn, Pb, Cu, Cd), ranged from 24 93%, while mass reductions 57...
