油脂碱炼水洗废水的再利用

Recycling of washed wastewater occured in oil alkali refining process

对油脂碱炼过程中的水洗废水进行再利用研究。将水洗废水经调和处理后,用于大豆毛油脱胶,通过单因素试验与正交试验,确定了最优脱胶工艺条件为:碱炼水洗废水添加量为油质量的10%,反应时间35 min,脱胶温度75℃,搅拌速度70 r/min。在此条件下,脱胶油的磷含量为9.6mg/kg。

Washed wastewater from oil alkali refinin wastewater, it was used to degum the crude soybean g process was recycled. oil. The optimum condit After the treatment of washed of degumming were mined by the single factor and orthogonal tests as follows ： washed wastewater amount 10% （based mass of the oil） , reaction time 35 min, degumming temperature 75℃ , stirring speed 70 r/min. the above conditions, the phosphorus content of the obtained degummed oil was 9.6 mg/kg. deteron the Under
