摘　　要：以管式陶瓷膜为基膜、以二氧化锆为涂膜颗粒,采取错流微滤方式制备7通道无机质基油水分离动态膜。在前期单通道实验研究的基础上,考察油水分离主要影响因素,如涂膜因素(涂膜流量、涂膜压差、涂膜温度及颗粒含量)和分离操作因素(操作压差、油水乳化液pH)对分离性能的影响。结果表明,随涂膜液流量、温度、颗粒含量和分离操作压差的增大,动态膜稳定渗透通量增大;而随着涂膜压差以及油水pH的增大,稳定通量则呈现先增大后减小的趋势。研究结果可为进一步开展的动态膜油水分离放大效应研究及工业化应用提供指导。Tubular porous ceramic membrane was used as substrate and Zirconium dioxide（ZrO_2） particles were selected as coating materials. Hydrophilous dynamic membrane（DM） was prepared and applied to cross-flow microfiltration of oil-in-water emulsion. On the basis of previous studies on singlechannel membrane module, a seven-channel membrane module of device is re-designed to analyze the influences of operating conditions（preparation pressure, flow, temperature, particles content） of the preparation and separation process. Experimental results show that with the increase in the coating flow, coating temperature, the content of coating flow and operating pressure, the permeation flux increase. However, with the decrease of coating pressure and the p H of oil-in-water emulsion, the permeation flux first increase, and then decrease. The work carried out in this article will support further theoretical and experimental study on the industrialization and amplification effect of the separation of oil-in-water emulsion with dynamic membrane.
