Development of Kinetic Models and Simulation of Operational Factors for Biological Nitrification-Denitrification Process with Nitrified Liquor Recirculation

Abstract

In sewage treatment, the nitrification-denitrification process with nitrified liquor recirculation (NDPR) is mainly adopted for nitrogen removal. Bench-scale experiments on NDPR were carried out. Based on the results obtained, kinetic models of NDPR were developed and their parameters were determined. It was shown that computer simulation using these models is effective in order to investigate the optimal method of operation.
