Biological Denitrification Technology of Sewage via delta15N Identification

In order to investigate the quantitative relations of nitrogenous compounds in the seal system and dynamic systems by molecule recognition technologies, the stable isotope 15
N technology was adopted to identify these nitrogenous compounds. Experiment results showed that it's effective for the 15
N identification technology to measure the quantitative relation of denitrification reaction. Furthermore, the denitrification could enrich 15
N in its products, while the nitrification decreases the content of 15
N in its products.
