Carbon, Nitrogen and Phosphorus Tranformations are Related to Age of a Constructe Wetland

Popis výsledku v původním jazyce

Two horizontal constructed wetlands with subsurface flow (CWs) of different age were monitored in a 2-year study. One of the CWs was new, while the second one had been in operation for 5 years in the first year of study. Transformations of C, P, and N were measured in each CW in the substrate of the vegetated bed under both aerobic and anaerobic conditions, and their rates were compared. C was mineralized in both CWs under both aerobic and anaerobic conditions, but mineralization rates differed betweenthe CWs; they were cca ten times higher in the established CW compared to the new CW. Dissolved reactive phosphorus (DRP) was immobilized under aerobic conditions but was mobilized under anaerobic conditions. DRP transformation was cca five times fasterin the established CW. Nitrification occurred under aerobic conditions at similar rates in both CWs. NH4 (+) concentration decreased under both aerobic and anaerobic conditions, but there was large variability. The age of the CW affected
