Abstract:

The combined process"coagulation - gas floatation - anoxia - aerobic"has been used for treating highly concentrated slaughter house organic wastewater. When the COD_Cr of the influent water is 10 000 mg/L and the SS is 400 mg/L,an average value of COD_Cr of the effluent water reaches 80 mg/L and the SS reaches 40 mg/L. The removal rates of CODCr and SS are 99.2% and 90% respectively. This process is characterized by stable running,efficient treatment and low cost, etc. It can be widely used for treating the birds processing slaughter wastewater.

Key words: wastewater treatment, coagulation-gas floatation, anoxic aerobic

摘要：

采用"混凝气浮—缺氧—好氧"组合工艺处理屠宰场高浓度有机废水,在进水COD_Cr、SS分别为10000、400mg/L的情况下,出水平均值分别达到80、40mg/L,COD_Cr、SS的去除率分别为99.2%、90%。该工艺具有运行稳定、处理效率高、运行费用低等特点,能广泛应用于禽类屠宰加工废水的处理。
