摘要：
介绍了预处理—复合厌氧—生物接触氧化工艺处理油脂工业废水的设计和运行调试工程实例。运行结果表明，以复合厌氧—生物接触氧化为主体的工艺处理高浓度的油脂加工废水是适宜的，该工艺处理负荷高、运行稳定，在进水COD、BOD5、SS和油类分别为32471.0～41674.5mg/L、12751.0～16138.3mg/L、3496.9～9502.3mg/L和271.6～592.3mg/L情况下，出水COD为76.9～86.0mg/L、BOD518.0～21.3mg/L、SS26.0～52.0mg/L、油类1.05～4.96mg/L，达到了设计要求。

Abstract:
The design and debugging engineering example of the treatment of the wastewater from edible oil production by pre-treatment and composite anaerobic and biological contact oxidation process are introduced mainly. The operating results indicate that, as the main process, the technology is fit for treating highly concentrated lipid wastewater, and has high load and steady operation. When the COD, BOD 5, SS and lipid of in-flow are 32 471.0-41 674.5 mg/L, 12 751.0-16 138.3 mg/L, 3 496.9-9 502.3 mg/L and 271.6-592.3 mg/L, the out-flowreaches the designing standard, which COD, BOD 5, SS and lipid are 76.9-86.0 mg/L, 18.0-21.3 mg/L, 26.0-52.0 mg/L and 1.05-4.96 mg/L.
