摘　　要：陶瓷膜污水处理技术近年来在油田含油污水领域得到了迅速发展,跨膜压差、处理温度以及油滴和悬浮颗粒的浓度都直接关系到膜处理时对离散相粒子直径的选择性和处理效果.运用Fluent计算软件在微观上对含油污水的处理条件(包括跨膜压差、温度以及含油污水的浓度)进行了数值模拟研究,结果表明,在适当的跨膜压差下,提高污水处理温度,减小含油污水浓度(进行污水预处理)可以减小膜污染的程度,从而明显地提高污水处理的效果.The ceramic membrane is widely used in the treatment of oilywater in the recent years. The treatment process of oilywater, including transmembrane pressure differential, processing temperture and the concentration of oil droplets and suspended particle are closely related to particle diameter selecticity of diseret phase. This paper simulates the influnce of those factors at a mirolevel using FLUENT software. The results show that under proper transmembrane pressure differential , membrane pollution is greatly reduced and the filtering effect is greatly improved as well by increaing processing temperature and minimizing the concentration of the oily droplets and suspension particles （by pretreatment of oily wastewater）.
