摘要

将超声波用于强化电解质溶液在纳滤膜内的传质过程，研究超声作用下NaCl和MgSO4溶液在聚酰胺纳滤膜内的传质机理，考察超声作用对膜通量、截留率和跨膜电位随跨膜压差变化规律的影响。实验结果表明，与无超声作用相比，施加在膜表面的超声作用增大了膜通量，降低了截留率，提高了跨膜电位。

Abstract

The potential use of ultrasonic treatment on the nanofiltration membrane for enhancing the electrolyte aqueous solution in the nanofiltration membrane transport was investigated. The mechanisms for mass transport of the electrolyte solution in the nanofiltration membrane with ultrasonic treatment were researched by an embedded ultrasound transducer and the cross-flow nanofiltration integrated experiments with NaCl and MgSO4 in single-salt aqueous solution

the operating variables studied were feed concentra-tion (2-30 mol·m-3) and applied pressure (0.1-0.26 MPa). It was observed that the observed rejections of NaCl and MgSO4 with ultrasonic treatment were lower than those without ultrasonic treatment in constant feed concentration. However

the membrane flux and streaming potential with ultrasonic treatment were higher than those without ultrasonic treatment in constant feed concentration.
