离子交换是四级截留制水系统的重要环节,它与注射用水的质量密切相关。而离子交换树脂的再生是保证其使用的关键性操作,合理的再生可以使树脂较长时间地保持良好的交换能力,并可延长其使用寿命。我们根据实践,总结出了较为合理的再生方案,介绍如下:1树脂的反冲和再生顺序:在反冲树脂时应先从最后一根树脂柱开始,而后逐一向前分别进行反冲。这样即可以保持原有未反冲柱的交换能力,以较优质的水进入下一柱内,同 Ion exchange is an important part of the four-stage retention system, which is closely related to the quality of water for injection. The ion exchange resin regeneration is to ensure that the use of the key operations, a reasonable regeneration can make the resin to maintain a good long-term exchange capacity, and can extend its service life. According to the practice, we concluded a more reasonable regeneration program, described as follows: 1 resin recoil and regeneration sequence: In the recoil resin should be the first resin column from the beginning, and then one by one forward separately for recoil. So that you can maintain the original non-recoil column exchange capacity to higher quality water into the next column, with
