Abstract
The increase in the European and Spanish agricultural and livestock sector has intensified the global pressure from overuse and production of nitrogen. European normative reflects the need to protect water against pollution caused by nitrates. This research aims to study the efficiency of nitrogen and other pollutants removal in pig slurry through constructed wetlands with two hydraulic retention times (3 and 7 days). Results pointed out higher removal for 7 days of retention. The system of treatment showed high efficiencies of purification, except for Cl- and Na+.
