摘　　要：通过实验室内测试研究了不同离子膜材料、阳(阴)极电解液质量以及电解液加热与否等多种运行条件下离子膜电解次氯酸钠装置的短期电解性能,并研究对比了3种运行条件下电解装置的长期运行效果。结果表明,离子膜法电解次氯酸钠发生方法在有效氯浓度、盐耗、电耗方面性能优异,采用氯碱行业回收离子膜,普通食盐水和自来水分别作为阳极液和阴极液情况下,电解性能并未发生显著变化;但长期运行时,建议阴极采用纯水,并对电解槽或电解液进行加热,同时需定期更换离子膜。In this paper, laboratory tests are done under realizable operation conditions to observe the operation effects of membrane electrolytic sodium hypochlorite generation device, from three aspects： membrane material, the brine quality into the anode, the wa- ter quality into the cathode. At the same time, the effects on the operation results are studied whether the electrolyte is heated or not. Then, the current efficiency of the ion-exchange membrane cell changes over time is monitored. The results show that ion-ex- change membrane electrolytic sodium hypochlorite generation method has a good performance in chlorine concentration, salt con- sumption and power consumption. If the iowexchange membrane recovering from the chlor-alkali industry is used, the ordinary brine water and tap water are respectively used as the anolyte and catholyte, the electrolysis performance does not change significantly. However, in the long-term operation, electrolyzer should he heated and pure water should be used as eatholyte. At the same time, the ion-exchange membrane should be replaced at regular intervals.
