%X The subsurface-flow constructed wetland is composed of three beds with area of 900m2 each.The average flows of system at the filtration rate 0.52m/d are 6m3/d,18m3/d and 30m3/d respectively.The average concentrations of pollutant influent are COD 40108mg/L,BOD5 31 88mg/L,mineral oil 24.67mg/L,and TN 11.67mg/L.Analytical results showed that COD decreased 67.25%-80.77%,BOD5 decreased 80.02%-89.05% mineral oil decreased 24.67%,and TN decreased 75.32%-82.43%,It indicates that wetland can provide an efficient and economical treatment system.
