摘　　要：对浓室填充树脂的电去离子(ED I)模块进行试验研究。结果表明,浓室填充树脂对ED I模块的运行效率产生了较大影响,同样条件下其电流效率和产水水质大大提高、能耗降低,且其浓水pH值较低,有利于防止浓室结垢,延长了模块的使用寿命,是一种更有发展前景的高纯水制备技术。The EDI module with concentrated compartments filled with exchange resins was stud- ied. The results show that the concentrated compartments filled with exchange resins have a greater influence on the operation efficiency of EDI module. Under the same condition, its current efficiency and produced water quality are enhanced obviously, the energy consumption is reduced. And its lower pH value is helpful for preventing concentrated compartments from scaling, extending the service life of the module, so it is one kind of high pure water preparation technology that has the great prospects for development.
