摘　　要：使用重力流膜滤技术应对西北高寒牧区水源地饮用水中关键水质因子浊度、氨氮以及高锰酸盐指数超标等问题,通过模拟西北高寒牧区冰山融雪水,经过多种重力流膜分离技术的处理,其在保证稳定的通量下,浊度、氨氮以及高锰酸盐指数三个关键水质指标完全符合GB 5749—2022《生活饮用水卫生标准》。The gravity flow membrane filtration technology was used to address the issues of key water quality factors such as turbidity,ammonia nitrogen,and permanganate index exceeding the standard in drinking water sources in the northwest alpine pastoral area.By simulating the melting snow water from icebergs in the northwest alpine pastoral area and processing it with various gravity flow membrane separation technologies,the three key water quality indicators of turbidity,ammonia nitrogen,and permanganate index fully comply with GB 5749—2022"Hygienic standards for drinking water"while ensuring stable flux.
