摘　　要：采用无机陶瓷膜过滤技术处理食用油脂碱炼废水，并将处理后的废水应用于大豆毛油脱胶工艺中，通过单因素试验及响应面试验对脱胶条件进行优化，确定大豆毛油水化脱胶的最佳工艺条件为：陶瓷膜处理后的废水添加量2．5％，搅拌速度100r／min，脱胶温度70℃，脱胶时间75min。在最佳脱胶条件下，脱磷率达到97．40％。The alkali refining wastewater produced by edible oils refining was treated with inorganic ce- ramic membrane filtration technology, then was used for hydrated degumming process of crude soybean oil. Based on the single factor experiments, response surface experiments were used to optimize the hy- drated degumming conditions. The results showed that the optimal hydrated degumming conditions were as follows： treated wastewater dosage 2.5% （ on the basis of crude soybean mass ）, stirring speed 100 r/min, reaction temperature 70℃, reaction time 75 min. Under the optimal conditions, the dephos- phorization rate was 97.40%.
