膜技术在农村饮用水处理中的研究与应用现状

    Research and Application of Membrane Technology for Safe Drinking Water in Rural Areas

    • 摘要: 农村饮用水安全是居民安全、经济发展的重要因素, 传统的农村水处理技术已经无法满足当前的安全供水需求。本文通过文献计量学结合VOSviewer可视化工具分析国内外农村饮用水的相关研究, 得出国内外研究热点均集中在农村饮用水安全保障和水质上, 我国在饮用水管理及处理技术方面研究相较国外较少。突现词分析表明对饮用水中氟化物治理和风险评估已经成为我国农村饮用水处理的主要发展方向, 而安全供水、超滤技术和传统过滤技术成为国外农村饮用水处理的主要发展方向和关键技术。同时, 本文综述了膜技术在农村饮用水污染物去除方面的研究进展, 发现纳滤技术(NF)能解决水源水铁、锰、砷和氟等污染物超标问题, 具有很好的应用前景。最后, 从水源特点、处理工艺流程和处理效果等方面调研总结了以超滤(UF)膜技术为核心的组合工艺在农村地区饮用水领域的应用情况, 进而提出进一步推广膜技术的相关建议, 可为保障农村饮用水安全和推动农村供水高质量发展提供技术支撑。

       

      Abstract: Safe drinking water is crucial for the wellbeing and economic development of rural residents. Traditional water treatment technology in rural areas cannot meet the current demand for a safe water supply. This study combined bibliometrics with a VOSviewer visualization tool to analyze the state of research on rural drinking water within China and internationally. The study found that both Chinese and international research focused mainly on ensuring safe rural drinking water and improving water quality. However, compared with international research, there was relatively less emphasis on drinking water management and treatment technologies in China. Analysis show that fluoride control and risk assessment in drinking water have become the main development directions for rural drinking water treatment in China. Meanwhile, ensuring safe water supply, ultrafiltration technology, and traditional filtration technology have emerged as the main development directions and key technologies for rural drinking water treatment in other countries. We reviewed the progress of membrane technology research in the removal of pollutants in rural drinking water and found that nanofiltration technology was highly efficient at removing iron, manganese, arsenic, and fluoride from contaminated drinking water, indicating a good application prospect. We summarized the application of hybrid ultrafiltration membrane technology for drinking water in rural areas, on the basis of the water source properties, treatment process, and performance. We suggest a range of applications of membrane technology in rural areas. This review provides technical support for safe rural drinking water and promotes the high-quality development of the rural water supply.
