试验研究表明，采用中空纤维膜过滤食醋，其膜通量随着过滤料液流量或过滤操作压力的增加而增加，但运行一段时间后，膜通量呈下降的趋势，且逐渐趋于一稳定值。%This experimental study showed the membrane flux of hollow fiber membrane was provided by in-creasing the flow rate of feeding or increasing the pressure of operating,but,the membrane flux was de-creasesing and tending to a stable value with the extension of the running time.
