电渗析法淡化的海水含硼4.7mg/l,长期饮用含硼量高的水,可能对身体不利。本文对564型硼选择性树脂的脱硼作用做了初步研究,得出了含硼5mg/l淡化水在25℃C时,以0.2,0.3,0.4床体积/分流速下的穿流曲线。研究了再生剂用量对脱硼的影响,给出五条不同再生条件的穿流曲线,从而确定最佳再生剂用量。本文还研究了洗脱流出液的酸碱度及其处理方法。

Electrodialysis desalination of seawater containing boron 4.7mg / l, long-term consumption of high boron content of water, may be adverse to the body. In this paper, a preliminary study on the deboronation of 564 boron selective resin was carried out. The flux curves of boron 5mg / l desalinated water at 25 ℃ at 0.2, 0.3 and 0.4 bed volume / min were obtained. The effects of the amount of regenerant on the deboronation were studied, and the flow-through curves of five different regeneration conditions were given to determine the optimal amount of regenerant. This paper also studied the pH of elution effluent and its treatment methods.
