摘　　要：通过改善界面电阻来优化电渗效率受到了广泛关注。基于磁电化学研究,开创性地将磁场引入电渗过程中,旨在降低界面电阻并提高电渗效率。通过试验证明引入磁场能显著提高电渗效率,且最佳的布置位置为阳极处。具体而言,合理布置磁场能够大幅延缓阳极界面电阻的上升,改善电渗排水性能,大幅缩短了处理时间。能耗方面,采用了多个指标进行综合分析,包括等效能耗、总能耗、能量利用率,结果表明引入磁场是解决电渗高能耗问题的有效途径,尤其当磁场布置在阳极处,能大幅提高能量利用率并减小总能耗。其中,采用可重复使用的永磁体作为磁极,能够循环使用且成本低廉。因此,在客观上,电渗中引入磁场的技术极具工程应用潜力和实践价值。The optimization of electroosmotic efficiency by improving interface resistance has received widespread attention.Based on the researches on magneto electrochemistry,a magnetic field is innovatively introduced into the electroosmotic process,aiming to reduce interface resistance and improve electroosmotic efficiency.Through experiments,it is demonstrated that introducing a magnetic field can significantly improve the efficiency of electroosmosis,and the optimal placement is at the anode.Specifically,a reasonable arrangement of magnetic fields can significantly delay the increase in anode interface resistance,improve the electro osmotic drainage performance,and significantly shorten the processing time.In terms of energy consumption,multiple indices are employed for comprehensive analysis,including equivalent energy consumption,total energy consumption and energy utilization rate.The results show that introducing a magnetic field is an effective way to solve the problem of high energy consumption in electroosmosis,especially when the magnetic field is arranged at the anode,and it can significantly improve energy utilization rate and reduce total energy consumption.Among them,the reusable permanent magnets are used as magnetic poles,which can be reused and have low cost.Therefore,objectively speaking,the technology of introducing magnetic fields in electroosmosis has great engineering application potential and practical value.
