摘　　要：公路桥面径流载体基质材料的选择至关重要。试制碳基铁合金催化载体对水体中的常见污染物和重金属具有高效的净化作用。本课题比较了四种高速公路桥面径流处理滤料材料(生物陶粒、生物沸石、铁碳微电解填料和特制碳基铁合金催化载体),并评估它们的净化能力。根据不同比例组合渗碳体稳定型、催化增强型、微电极活化型和吸附调整型材料,设计了10种组合体载体。通过真实模拟情况的实验,明确了具有良好净化性能和环保效益的最佳组合体载体是渗碳体稳定型、催化增强型、微电极活化型、吸附调整型材料的比例为25%、15%、10%、50%的组合体载体滤料材料。The choice of substrate material for road bridge runoff carriers is crucial.The pilot carbon-based iron alloy catalytic carrier is highly effective for the purification of common pollutants and heavy metals in water bodies.Four highway bridge runoff treatment media materials(biotite,bio-zeolite,iron-carbon micro-electrolytic filler and a special carbon-based ferro-alloy catalytic carrier)were compared and their purification capacity was evaluated.Ten combinatorial carriers were designed based on different combinations of carburate-stabilised,catalytically enhanced,microelectrode activated and adsorption adjusted materials in different proportions.Through experiments with realistic simulated situations,it was determined that the best combination carriers with good purification performance and environmental benefits are those with 25%,15%,10%and 50%of carburite-stabilised,catalytically enhanced,micro-electrode activated and adsorption-adjusted materials.
