摘　　要：如何保障农村饮用水安全是研究者一直关注的重点问题。生物慢滤技术具有建造方便、制水成本低、能源消耗低、运行稳定可靠等优点,其较城市更加适合在农村进行推广。针对水资源短缺及饮用水安全问题,介绍了该技术对浊度、有机物、氮磷、细菌、金属等污染物的去除效果,比较了生物慢滤技术的优缺点,展望了未来生物慢滤技术的应用前景。It has been a focus for researchers to study how to ensure the safety of drinking water in rural areas.Bio-sand filtration(BSF)technology has advantages including convenient construction,low water production costs,low energy consumption,and stable and reliable operation,and thus it is more suitable for promotion in rural areas than that in cities.Considering the water shortage and drinking water safety issues,this paper introduces the removal effects of BSF on pollutants such as turbidity,organic pollution,nitrogen and phosphorus,bacteria,and metals,and the advantages and disadvantages of BSF are compared.Moreover,the future application prospects of BSF technology are discussed.
