The aim of present study was to design and construct an Up-flow Anaerobic/Aerobic Fixed Bed (UA/AFB) combined reactor in which an anaerobic and aerobic zones could run in a single reactor to study simultaneously carbon and nutrient removal. The UA/AFB developed reactor was made from Plexiglas plate consisting of two main lower anaerobic and upper aerobic parts. A synthetic wastewater was prepared in concentrations which were close to those found in municipal wastewaters. After developing the biofilm on the media, reactor was operated at 5 different HRTs ranging from 5 to 24 h. Samples collected at any HRTs from influent and sampling ports in steady state condition were analyzed according to standard methods for COD, NH3 , NO-3, PO4-3, alkalinity and pH. The obtained results showed that the HRT of 7 h was suitable for simultaneous removal of COD, nitrification and denitrification. In this HRT efficiencies are 95.4, 94 and 94.5% for COD removal, nitrification and denitrification, respectively. The reactor did not show good performance in phosphorus removal. |
