Study on planting form for Bio-Retention cell Based on SWMM
Eight kinds of plant volume and surface roughness combinations for runoff reduction,peak delay and removal of pollutants(SS and COD)from Bio-Retention cell basin intervention facilities were derived from SWMM simulations.The biological and pollution remov-al rate characteristics of commonly used plants obtained from the field study were combined with ecological and ornamental principles to plant these eight combinations in the sample plots.Online monitoring of the sample plots showed that the monitoring data were consistent with the simulated data.Therefore,it is recommended that these eight planting forms be promoted and applied in actual projects.
