Removal of acidic pharmaceuticals by small-scale constructed wetlands using different design configurations

Popis výsledku v původním jazyce

To better understand the performance of constructed wetlands to remove acidic pharmaceuticals AP in wastewaters in subtropical areas and to optimize CW design criteria, six small scale CWs under different design configurations were operated. The factors such as environmental parameters, water quality, and seasonality influencing the removal were also analyzed to illustrate the removal mechanisms. The results indicated that the best performances were up to 80 to 90 percent. Subsurface flow systems showed high removal efficiency for ibuprofen, gemfibrozil and naproxen, but surface flow systems performed better for ketoprofen and diclofenac. The positive relationship between the removal efficiencies of ibuprofen, gemfibrozil, and naproxen with dissolved oxygen and ammonia nitrogen reveals that SSF CWs under aerobic conditions benefit the biodegradation, while the favorable conditions created by SF CWs for receiving solar radiation promote the effective photolysis of ketoprofen and diclofenac.
