摘　　要：微塑料在海洋、湖泊等水体中频繁检出,但在饮用水中有关微塑料的研究甚少,其在饮用水中的存在现况和健康效应仍难以确定。文中阐述了近年来微塑料在饮用水中的存在现况、健康效应,分析了混凝沉淀、砂滤、臭氧氧化-活性炭过滤工艺对于微塑料的去除效率,并展望了微塑料在饮用水领域中的研究进展,对当前饮用水中微塑料研究存在的问题提出了建议。Microplastics are frequently detected in oceans,rivers and lakes.However,there are few studies on microplastics in drinking water.It is difficult to determine health effect and existing status of microplastics in drinking water.In this paper,existing status and health effect of microplastics in drinking water field in recent years,as well as the purification process of microplastics in drinking water by waterworks are described.Removal efficiency of microplastics by coagulation sedimentation,sand filtration and ozone oxidation activated carbon filtration processes is analyzed.Research and development of microplastics in drinking water are prospected,and existing problems in the research of microplastics in drinking water are proposed.
