结合工程实例,介绍采用二级接触氧化工艺处理屠宰废水,实例表明此工艺运行稳定,处理效果比较好,当进水COD质量浓度为2780mg/L,采用此工艺处理后出水中COD_Cr为49mg/L,出水水质达到北京市《水污染排放标准》中的第二级标准(新改扩),并介绍了处理该废水的运行费用。

Based on the engineering example, slaughter-house wastewater can be treated by the two-stage biological contact oxidation process. The engineering example shows that the two-stage biological contact oxidation process is feasible for slaughter-house wastewater treatment. With the influent of COD 2780 mg/L, the COD of effluent is less than 49 mg/L. The operation expenses of the unit are presented. The quality of the effluent water is up to the second level in the Beijing Standard.
