Abstract

An upflow microaerobic sludge reactor (UMSR) was constructed in treating manure-free piggery wastewater with high ammonium concentration and a COD/TN ratio as low as 0.84. The UMSR offered an outstanding removal of NH₄⁺-N and TN at 35°C and hydraulic retention time 8h subsequent to inoculated sludge acclimation. A short NO₂^--N accumulation phase was observed whenever there was a considerable increase in TN loading rate (NLR), but decreased rapidly along with an evident increase in TN removal. Fed with raw wastewater at a NLR of 1.10kg/(m³d), the average COD, NH₄⁺-N and TN removal reached 0.72, 0.76 and 0.94kg/(m³d), respectively. Inference drawn from stoichiometry based on the potential nitrogen removal pathways and the C/N ratio required by denitrification indicated that anammox was the main mechanism for NH₄⁺-N and TN removal in the UMSR.
