文摘

Elevated concentrations of pharmaceutical residues in surface waters are observed due to discharge of wastewater effluent. The impact of aeration on the performance of a pilot constructed wetland was studied. Continuous aeration facilitated efficient removal of organic matter and ammonium at high organic loading. The removal of pharmaceuticals metformin and valsartan was significantly improved during aeration.
