摘要
Binzhou section of Changshen highway was selected to study the effectiveness of road sweeping in decreasing the pollutant loads of highway runoff. With on-site continuous sampling, the discharge rules of Cu, Cd, Pb and Zn are analyzed. The total and dissolved event mean concentrations of Cu, Pb and Zn are calculated, and the loads of heavy metals attached to particles sampled before and after rainfall are also studied. A test section on highway road was swept in different frequencies during a week and the amount of removed particles was measured. Based on the analysis of highway runoff and road sweeping, a prediction equation is established to calculate the pollution control efficiency of the sweeping measure, and the results indicate that the 1 time/week road sweeping method can remove 47.93% of dissolved Cu, 46.87% of Pb and 44.21% of Zn. © Copyright.
