Major findings:A. faecalis strain No. 4 was used to treat high-strength ammonium in solids-free piggery wastewater (SFW) in both batch and continuous systems. Based on the fact that no nitrified products were detected suggested that strain No. 4 exhibited its abilities of heterotrophic nitrification and aerobic denitrification in the piggery wastewater.

Abstract:Alcaligenes faecalis strain No. 4, which has heterotrophic nitrification and aerobic denitrification abilities, was used to treat actual piggery wastewater containing high-strength ammonium under aerobic conditions. In a continuous experiment using a solids-free wastewater (SFW) mixed with feces, almost all of the 2000 NH4+ -N mg/L and 12,000 COD mg/L in the wastewater was removed and the ammonium removal rate was approximately 30 mg-N/L/h, which was 5-10 times higher than the rates achieved by other bacteria with the same abilities. The denitrification ratio was more than 65% of removed NH4+ -N, indicating that strain No. 4 exhibited its heterotrophic nitrification and aerobic denitrification abilities in the piggery wastewater.
