文摘

Dissimilatory nitrate reduction processes were associated closely with sediment properties. Denitrification, anammox and DNRA contributed 50.2%, 40.5% and 9.3% to total nitrate reduction. Denitrification and anammox removed about 20.1% of total inorganic nitrogen. High loading of nitrogen retained in urban rivers may cause serious water pollution.
