芦荟丁蔗糖浸泡液中蔗糖的回收

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·(m2·h)-1；一级纳滤系统的蔗糖回收率为95%，平均通量为111 L·(m2·h)-1；二级纳滤系统蔗糖的回收率为99%，平均通量为205 L·(m2·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。

Sucrose Recovery from Sucrose Solution of Aloe Pieces

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·(m2·h)-1,95% in the primary nanofiltration system with an average flux of 111 L·(m2·h)-1,and 99% in the secondary nanofiltration system with an average flux of 205 L·(m2·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
