A novel disinfection device based on ionic membrane electrolysis technology was developed in this study. To test the feasibility of the newly developed system in rural and emergency water supply, biological assay for the electrolytic system was carried out. The biological efficacy results show that a high concentration of coliform bacteria can be effectively inactivated both in synthetic contaminated water and natural source water, while the chemical indicators of water quality changed only slightly after disinfection. To reduce the operating cost of the system, the electrolyte feeding method and flow rate of the electrolytic cell were optimized. Results of operating conditions show that the operation cost can be reduced by changing the electrolyte feeding method from pump‐driven to gravity‐driven. As the flow rate was 2.4 L ·h⁻¹, the system has the lowest operation cost, which was 93% lower than adding commercial sodium hypochlorite solution. This paper suggests promising applications of the novel disinfection device based on ionic membrane electrolysis technology in drinking water disinfection or emergency water treatment. © 2020 International Commission for Irrigation and Drainage

基于离子膜电解技术的新型消毒装置：生物功效测定和最佳操作条件*

本研究开发了一种基于离子膜电解技术的新型消毒装置。为了测试新开发的系统在农村和应急供水中的可行性，对电解系统进行了生物测定。生物学功效结果表明，高浓度的大肠菌可在合成污水和天然水中被有效地灭活，而消毒后水质的化学指标仅发生了轻微变化。为了降低系统的运行成本，优化了电解质的进料方法和电解池的流速。运行条件的结果表明，通过将电解质的进料方式从泵驱动改为重力驱动，可以降低运行成本。流量为2.4 L·h^-1，该系统的运行成本最低，比添加商业次氯酸钠溶液低93％。本文提出了基于离子膜电解技术的新型消毒装置在饮用水消毒或应急水处理中的应用前景。©2020国际灌溉排水委员会
