Abstract:A composite filler bioretention column was constructed by using natural soil, construction sand, sawdust compost, zeolite, anthracite and gravel as packing media. The purification effects of retention column on COD, TP, NH+4-N and TN in surface runoff of expressway service area were evaluated through artificial simulation test, and the spatio-temporal degradation characteristics of runoff pollutants in the packing layer of retention column were analyzed. The results show that the composite filler bioretention column has a good removal effect on runoff pollutants. The average concentration reduction rates of COD, TP, NH+4—N and TN by bioretention column under the three inflows condition are 80.2%, 73.3%, 91.1% and 63.9%, respectively. During the inflow period, the outflow concentration of COD, TP and NH+4—N decreases along the depth of the filler layer, while the outflow concentration of TN fluctuates significantly. Within 12 to 144 hours after the stopping of inflow, with the time prolonging, the COD concentration gradually increases in the planting soil layer, but gradually decreases and stabilizes in the sand filter layer and gravel layer; the TP concentration gradually decreases and stabilizes in the three kinds of filler layers; the NH+4—N concentration decreases at first and then gradually increases in the planting soil layer, but gradually decreases and stabilizes in the sand filter layer and gravel layer; the TN concentration decreases at first and then increases gradually in the planting soil layer and sand filter layer, but gradually decreases and stabilizes in gravel layer.
