摘要

Two separate constructed treatment wetland (CTW) ssytems receiving the same metal contaminated, acid sulfate water over different lengths of time and at different rates are evaluated for metal attenuation. Both wetlands are the alkalinity. generator portion of a succesive alkalinity producing system (SAPS). Sequential extractiosn are employed to determine phases of metal removal. Results indicate that Fe, Al, Zn, Ni, and Cu accumulate in the organic substrate over time. Manganese accumulates initially, but is not retained in the system over time.
