Research on the Treatment Technology of Emulsion Wastewater from Mechanical Processing by Electric Flocculation with Aluminum Electrode

采用铝电极电絮凝法处理机械加工含乳化液废水.实验结果表明,最佳的电解工艺条件为:电解电压=35V,反应时间=60min,电解质NaCl投加量=0.10g/L,pH值=3,破乳剂CaCl_(2)投加量=10g/L.在此条件下,废水COD去除率可以达到956%,出水COD可以达到500mg/L以下.此方法具有处理效果好、反应时间短等优点,在含乳化液废水处理领域具有良好的应用前景.

Electric Flocculation with aluminum electrode has been used for the treatment of emulsion wastewater from mechanical processing.The results show that the optimal electrolytic process conditions are as follows:electrolytic voltage=35 V,reaction time=60 min,NaCl dosage=0.1 g/L,pH=3,CaCl_(2) dosage=1 g/L.Under these conditions,the COD removing rate of the wastewater can reach 95.6%,and the effluent COD can be less than 500 mg/L.This method has the advantages of satisfying treatment effect and short reaction time,and has a good application prospect in the field of emulsion wastewater treatment.
