隔油沉淀-预曝调节-接触氧化-气浮工艺处理屠宰加工废水

Treating Slaughtering Wastewater with the Process of Oil Separation and Sedimentation-Preaeration-Contact Oxidation-Floatation

对屠宰加工过程中产生的中高浓度有机废水采用预曝调节-接触氧化-气浮工艺进行处理。当进水COD浓度为980-1200mg／L时，出水COD浓度可降至76．1-104mg／L，优于国家《肉类加工工业水污染物排放标准》（GB13457--92）二级标准，此工艺的抗冲击负荷能力较强，适应于间歇性生产和季节性生产的屠宰加工企业。

The process of oil separation and sedimentation--preaeration--contact oxidation--floatation was used in trea- ting the high organic wastewater from slaughterhouse. When the inflow COD was 980-1200mg/L, the effluent COD was 76. 1-104mg/L,which was superior to the second level of ＂Discharge Standard of Water Pollutants for Meat Packing Industry＂ （GB13457--92）. The process has the advantage of shock load--resistant, which is suitable for interim or seasonal producting slaughterhouse.
