Abstract:
Anaerobic-anoxic-oxic baffled bioreactor（AAOBR） process has been used for treating wastewater from slaughterhouse. Better treatment effect is obtained under the different flow. At low-flow, the COD removal rate can be up to 96.3 %, and the SS removal rate in ABR zone is 90%, while at high-flow, the COD removal rate is 93.8%, and the SS removal rate in ABR zone is 80.6%. The removal rates of COD and SS in the treatment of slaughter wastewater by AAOBR process are discussed. It shows that the AAOBR process has good suitability for slaughter wastewater, and also has high capacity for anti-impact loading.

摘要：
采用厌氧—缺氧—好氧折流生物反应器(AAOBR)处理屠宰废水, 在不同流量下均取得了较好的处理效果。其中低流量下COD去除率为96.3%, ABR段SS去除率为90%;较高流量下COD去除率为93.8%, ABR段SS去除率为80.6%。同时探讨了AAOBR处理屠宰废水中COD、SS的去除规律。实验表明, AAOBR适宜处理屠宰废水, 且具有较高的抗冲击负荷能力。
