Soluble Organic Nitrogen Characteristics and Removal.

摘要

This report discusses sources,concentrations,characteristics and methods for removal of Soluble Organic Nitrogen (SON) in wastewater. Removal by various physical,chemical and biological processes are described and molecular weight distribution is characterized. A significant portion of the SON in secondary effluent is produced biologically during treatment. Chemical coagulation,ion exchange and activated carbon were used singly and in combination to characterize different fractions of the SON and the Soluble Chemical Oxygen Demand (SCOD).
