Study on Livestock and Poultry Farming Wastewater Treatment Using a Hybrid Baffled Reactor

Abstract:

In this paper aerobic process was applied in an anaerobic baffled reactor to form an innovative Hybrid Baffled Reactor (HBR), which was used to investigate the treatment effect of livestock and poultry farming wastewater. Biofilm cultivation, the influence of Hydraulic Retention Time (HRT) and treatment effect in three tanks were also discussed. The study result showed that good COD and NH₄⁺-N removal efficiency was achieved in the reactor. When the influent COD concentration, NH₄⁺-N concentration and HRT were 900 mg/L, 200 mg/L and 24 h, the concentrations of COD and NH₄⁺-N in the outlet were smaller than 100 mg/L and 70 mg/L, and COD removal efficiency and nitrification rate were 90% and 70% respectively.
