摘要
本文探讨了超滤(UF)、纳滤(NF)、反渗透(RO)等不同膜技术在自来水厂中的应用,包括颗粒物与微生物屏障、溶解性有机物与污染物深度去除、硬度与盐度调控、水源水质适应性提升等,然后基于实际案例,分析了不同膜技术在保障饮用水安全、降低消毒副产物、优化运行管理及经济可持续发展等方面的价值。由此得出,随着膜材料科学进步、工艺优化及规模化应用成本的持续下降,新型膜技术将成为未来高品质自来水生产的关键过滤技术。
This paper discusses the application of different membrane technologies such as ultrafiltration(UF),nanofiltration(NF)and reverse osmosis(RO)in waterworks,including particulate matter and microbial barrier,deep removal of dissolved organic matter and pollutants,regulation of hardness and salinity,and improvement of water quality adaptability.Then,based on actual cases,the value of different membrane technologies in ensuring drinking water safety,reducing disinfection by-products,optimizing operation management and sustainable economic devel⁃opment is analyzed.It is concluded that with the scientific progress of membrane materials,process optimization and continuous reduction of large-scale application costs,new membrane technology will become the key filtration technology for high-quality tap water production in the future.
