In order to optimize the bioretention facility media for municipal road runoff pollution control, a multi-objective evaluation method was employed to comprehensively evaluate the permeability performance, pollutant removal efficiency and economic cost of bioretention media. Based on the geographical conditions and municipal road runoff pollution characteristics in north China, a lab-based simulation experiment using bioretention columns was carried out. The results indicated that the optimized media was composed of natural soil, river sand, peat soil, water treatment residual(rich in aluminium salt), vermiculite and zeolite, with a mass ratio of 30∶24∶6∶20∶10∶10. The optimized media could maintain decent permeability and effectively remove runoff pollutants(SS, COD_Cr, TN, NH₃-N, TP), and also had characteristics of the localization of media and the recycling of solid wastes.
