Comparison of long-term phosphorus removal performance of two large-scale constructed wetlands in South Florida, USA

摘要

The Everglades Stormwater Treatment Areas (STAs) have been constructed as a component of the Everglades restoration in southern Florida, U.S.A. These large-scale treatment wetlands function to remove excess phosphorus (P) from agricultural and urban runoff. The STAs can receive variable inflow hydraulic and P loading in response to storm events or regional droughts and are operated under state and federal permits. An evaluation of the long-term P removal performance for two of the best performing STAs, STA-2 and STA-3/4 is presented along with the challenges in managing these large wetlands.
