摘　　要：利用超声耦合膜分离技术提取回收橡子淀粉生产过程中浸泡废水中的单宁。橡子超声浸泡液过一级膜除杂,再经过二级膜浓缩,喷干得到单宁,纯度为88.73%,高于企业标准,收率为11.3%。提高了橡子淀粉生产企业的经济效益,实现了清洁生产。The tannins of immersion waste water in acorn starch production are extracted by ultrasound coupled membrane separation technology. The ultrasonic acorn immersion liquid is purified by the first membrane equipment, and then concentrated by the second membrane equipment, at last dried by spray evaporating to obtain tannins. It＇s detected that the purity of tannins is 88. 73 % which is higher than industry standard and the yield is 11.3% . The method heightens the economy benefit and realizes cleaner production.
