Abstract:

The method of ultrasonic and biological contact oxidation for treating terylene wastewater is introduced. Also, the acclimation of sludge is introduced and the operating parameter is confirmed. The results of experiment show that the COD_Cr of influent water is about 1 000 mg/L and the effluent water is lower than 100 mg/L. The removal rate reaches over 90%. The effluent water is clean and transparent, and reaches the discharge standard.

Key words: terylene wastewater, biological contact oxidation, ultrasonic

摘要：

介绍了超声波预处理—生物接触氧化法处理涤纶废水，并介绍了接触池内污泥的驯化，确定了运行参数。实验结果表明，对于COD_Cr质量浓度在1000mg/L左右的涤纶废水，经过处理后，出水COD_Cr质量浓度<100mg/L，去除率在90%以上，出水清澈透明，达到了排放标准。
