超滤膜分离纳滤浓缩液中腐殖质的影响因素研究
|
摘要
纳滤浓缩液中HS纯度达80%以上,可资源化程度较高,选择适宜孔径的超滤膜可对其进行有效分离.选择切割分子量为3kDa的超滤膜,研究在不同压力(0.2、0.3、0.4、0.5 MPa)和不同浓缩比(2、5、10、15、20)条件下对HS的截留效率,研究结果表明:随着压力的升高和浓缩比的增大,HS截留率均呈下降趋势,其高低主要受FA截留效率的影响;当驱动压力为0.3 MPa、浓缩比为10时,分离效果较为适宜,HS截留率为39%,纯度为69%.
The purity of HS in nanofiltration concentrate is over 80%,and with a high degree of resources,it can be effectively separated by appropriate pore size of ultrafiltration membrane.The paper makes a study on the interception efficiency of HS under different pressure and different concentration ratio by using ultrafiltration membrane with a molecular weight of 3 kDa.The results show that with the increase of the pressure and the concentration ratio,the interception rate of HS is decreased,which is mainly influenced by the interception efficiency of FA.When the driving pressure is 0.3 MPa and the concentration ratio is 10,the separation effect is more appropriate,the rejection rate of HS is 39%,and the purity is69%.
