摘　　要：本研究对工业生产中下胶和酶处理后酒脚的黏度、固形物含量、COD值、溶解氧及pH值等指标进行测定;并采用陶瓷膜回收系统对不同类型的酒脚进行处理,测定处理后酒体的回收率、浓缩酒脚的残余量、酒脚回收时通量的变化以及回收后酒体溶解氧等指标。结果表明,系统对枸杞酒基酒酒脚、枸杞发酵酒酒脚的回收率分别为90.9%和87.6%,平均通量分别为11.4 k g/h和8.4 kg/h,回收后酒体溶解氧分别为94.8%和87.0%。In this study,the viscosity,solids content,COD value,dissolved oxygen and pH value of wine lees after fining and enzyme treatment were determined.Ceramic membrane recovery system was used to treat different types of wine lees,and the recovery rate of the treated wine,the residual amount of lees,the change of flux during the recovery process and the dissolved oxygen in the recovered wine were measured.The results showed that the recovery rates of the system for goji base wine lees and goji fermented wine lees reached up to 90.9%and 87.6%,respectively;the average throughput was 11.4 kg/h and 8.4 kg/h,respectively;the dissolved oxygen in the recovered wine was 94.8%and 87.0%,respectively.
