In this dissertation, twotransition-metal-flee catalytic aerobic oxidation systems were establishedwhich respectively use iso-amyl nitrite (IAMN) and tert-butyl nitrite(TBN) as the NO equivalen.

The reason of the aerobic oxidation to glycolysis is often taken as a sign of tissue hypoxia.

Evolution,mechanism and research progress of anaerobic ammonium oxidation technology for biological denitrification;

Cultivation and Nitrogen Removal Characteristics of ANAMMOX Granules;

Realization of ANAMMOX in a rotating biological contactor;

Several newly developed processes, such as shortcut nitrification-denitrification, simultaneous nitrification-denitrification (SND) and especially anaerobic ammonium oxidation (ANAMMOX), were reviewed and discussed .

Anaerobic ammonium oxidation (anammox) is a new field of biological nitrogen removal from wastewater,however,the anammox biomass with slowly-growing and strict demand of environmental conditions has become a big obstacle for the full-scale implementation of anammox.

With new theoretical development of biological nitrogen removal,nitrogen removal processes have been developed,such as short-cut nitrification and denitrification, simultaneous nitrification and denitrification and anaerobic ammonium oxidation (ANAMMOX),et al.
