采用微电解-絮凝法预处理含油乳化废水.结果表明,铁投加量为60g/L,铁炭质量比为20∶1,微电解反应16h,复配絮凝剂PAC用量为120 mg/L、PDA用量为12 mg/L时,对含油乳化废水的预处理效果最佳,COD去除率最高可达45%以上.
Micro-electrolysis-flocculation process has been used for the pretreatment of oil-bearing emulsion waste- water. The results indicate that the pretreatment effect of oil-bearing emulsion wastewater is the best,when iron dosage is 60 g/L, m (Fe) :m (C) 20:1, micro-electrolysis reaction time 16 h, synthetic flocculent dosage PAC 120 mg/L and PDA dosage 12 mg/L. The highest COD removing rate reaches 45%.
