摘　　要：为循环利用蔗糖溶液,减轻污水处理系统负荷,采用超滤、一级纳滤、二级纳滤的膜组合工艺,去除芦荟丁蔗糖浸泡液中的杂质,实现蔗糖回收。实验结果表明,超滤系统蔗糖回收率达到99%,平均通量为8.8 L·(m^2·h)^-1;一级纳滤系统的蔗糖回收率为95%,平均通量为11.1 L·(m^2·h)^-1;二级纳滤系统蔗糖的回收率为99%,平均通量为20.5 L·(m^2·h)^-1;浸泡液中的蔗糖可浓缩至30%;膜芯清洗后,可以恢复原通量,有效实现芦荟深加工的节能减排。Ultrafiltration,one-stage nanofiltration and two-stage nanofiltration were applied to purify the aloe-piece sucrose solution for its reuse and the reduction of the load of sewage treatment system.The results show that the sucrose recovery was 99%in the ultrafiltration system with an average flux of 8.8 L·(m^2·h)^-1,95%in the primary nanofiltration system with an average flux of 11.1 L·(m^2·h)^-1,and 99%in the secondary nanofiltration system with an average flux of 20.5 L·(m^2·h)^-1,and sucrose concentrated to 30%in the soaking solution.After cleaning,the original flux can be recovered,and energy saving and emission reduction in aloe deep processing effectively realized.
