Assessment of Nitrification in an RBC (Rotating Biological Contactor) Plant

摘要

The purpose of the study was to evaluate the performance of each stage in a train of an RBC system in terms of NH3-N removal. The specific objectives of the study were: (1) to determine the removal efficiency of soluble ammonia nitrogen (SNH3-N) and soluble organic nitrogen (SOrg-N) for each stage; (2) to ascertain the relationship between SNH3-N reduction and alkalinity, nitrate nitrogen (NO3-N), pH, and other factors; (3) to develop a nitrogen budget for each stage; and (4) to characterize NH3-N removal kinetics for design purposes. The report describes the RBC system at Princeton and the procedures and results of the study. It also includes a proposed RBC design approach.
