Abstract:

EF-H₂O₂-FeO_x-flocculation process has been used for the treatment of oil-bearing emulsion wastewater. The results indicate that when electrolytic voltage is 8 V, pH 2.5, reaction time 75 min, and PAM dosage 2 mg/L, the treatment effect on oil-bearing emulsion wastewater is the best. The highest COD removing rate can be higher than 93%. The method has the advantages of high efficiency, good removing effect, and is economic and functional. As a result, it has wide application prospect in the field of oil-bearing emulsion wastewater treatment.

Key words: emulsion wastewater, EF-H₂O₂-FeO_x-flocculation, wastewater treatment

摘要：

采用EF-H₂O₂-FeO_x—絮凝处理含油乳化废水。结果表明, 电解电压8 V, pH=2.5, 电解反应时间75 min, PAM投加质量浓度为2 mg/L时, 对含油乳化废水的处理效果最佳, COD的去除率最高可达93%以上。此方法具有高效、去除效果好、经济适用等优点, 在含油废水的处理领域具有广阔的应用前景。
