摘　　要：针对切削乳化废水稳定性高,COD值高及采用单一絮凝剂处理难以达到破乳目的等特点,自制出液体硅酸铝铁絮凝剂(PAFSi),优化了破乳、絮凝条件,得出了自制液体硅酸铝铁絮凝剂适用的pH值、投药量、温度、搅拌时间和强度等的最佳絮凝条件。实验结果表明,在pH≈5.8～6.5,投量为10.0￣12.0ml/100ml,温度50℃￣55℃的条件下,搅拌速度60r/min￣70r/min,用自制絮凝剂处理COD为98700mg/L的机械切削乳化废水,COD去除率达98.5%。In view of cutting emulsification wastewater has a high emulsification stability and a high COD value （chemical oxygen demand）, use of single flocculant demulsibility in treating the wastewater is not very effective, the article introduces a kind of liquid PAFSi which can optimize the flocculation and congealment condition, and its appropriate pH value, additive quantity, temperature, mixing time and intension. A test shows that 98.5% of COD can be removed when use the PAFSi in treating cutting emulsification wastewater with 98700mg/L of COD on the condition of 5.8-6.5 of pH value,10.0-12.0ml/100ml of adding amount,50- 55℃ of temperature and 60-70 r/min of mixing rate.
