Nitrogen and Phosphorus Reactions in Overland Flow of Wastewater

摘要

Biochemical transformations of labelled ammonium-nitrogen and nitrate-nitrogen resulting from the overland flow treatment of simulated wastewater are studied in small-scale test models. The factors controlling the nitrification and denitrification are discussed and the ultimate fate of the nitrogen species are determined. The mechanisms of phosphorus sorption and desorption are investigated under both laboratory and overland flow conditions.
