摘　　要：目的研究无机陶瓷膜微滤耦合超声技术在痹通药酒澄清过滤中的应用。方法以膜渗透通量、膜污染阻力分布等为指标,考察间歇超声、连续超声与未耦合超声在痹通药酒澄清滤过中的差异,进而对操作条件进行优化研究。结果连续超声可显著增强膜的渗透性能,渗透通量高达173 L/(m2.h),通量提高率31.6%,同时还能有效降低膜污染阻力,尤其对膜表面沉积层,降幅达50%以上。一定范围内,超声对膜过程的强化与操作压力呈正比,与操作温度呈反比。结论陶瓷膜微滤过程耦合超声技术是一种安全有效的膜分离手段。Objective To study the application of inorganic ceramic membrane microfiltration coupled with ultrasonic in the process of refining Bitong medicinal liquor.Methods Using flux and membrane fouling resistance distribution as index,the differences of intermittent ultrasound,continuous ultrasound,and non-coupled ultrasound in the clarify with Bitong liquor were studied.Results Continuous ultrasound could significantly enhance the membrane permeability,permeation flux as high as 173 L/（m2·h）,increase the rate of flux 31.6%,reduce membrane fouling resistance effectively,particularly,deposition on the membrane surface layer,and decrease more than 50%.Within a certain range,the enhance effect of ultrasound on the membrane process had a positive correlaton against operating pressure and a negative correlation against the operating temperature.Conclusion Ceramic membrane microfiltration with on-line coupling with ultrasonic technique is a safe and effective mean of membrane separation.
