Studies on Hybrid Reactor Consisting of Sequential Aerobic-Anoxic Systems for Nitrogen Removal Process from Industrial WasteWater, M.Sc. Thesis Sharif University of Technology ; Borghei, Mehdi (Supervisor)
Abstract
In this study, the biological nitrogen removal process from a wastewater with high COD and TKN concentration was investigated in a hybrid reactor. In order to remove nitrogen completely with pre-denitrification process, both moving bed biofilm system and fixed bed biofilm system with pumice stone, were used in a single reactor (volume is 16 l). Moving bed biofilm and fixed bed biofilm systems were considered in sequence, as aerobic and anoxic parts of the reactor. 35% of the aerobic volume was occupied with plastic carriers and 70% of the anoxic volume was occupied with pumice stone with an average diameter of 30mm. Experiments were done in 7 runs, for total hydraulic retention times of 30,...
