Ammonia nitrogen removal from melamine wastewater by biological fluidized bed

The purpose of the research project to be performed at the Zhejiang University of Technology is the study of the hydraulic characteristics associated with removal of ammonia nitrogen and chemical oxygen demand (COD) from wastewater treated in an anaerobic-aerobic fluidized bed. Most of the current biological denitrification processes are performed by some form of biological method but are only suitable for removal of relatively low ammonia nitrogen concentrations due to the requirement of an appropriate carbon to nitrogen ratio. Thus, there is a need to study the hydraulic characteristics of the proposed process in order to determine optimal reactor conditions for ammonia nitrogen removal. The main expected outcome of the research project is the achievement of maximum removal efficiency of both COD and ammonia nitrogen from melamine wastewater, which is made possible by a high resistance to organic loading in the reactor.
