摘　　要：给水管网是供水系统的重要组成部分,管壁生物膜生长及脱落会对龙头水水质造成一定影响,近年来国内外学者研究发现给水管网系统中广泛存在着微量无机污染问题。研究发现给水管网中的无机污染物大多累积在管壁生物膜中,当生物膜状态和水质条件发生变化时无机污染物会被释放至水中,对人体健康造成一定威胁。文章综述了管壁生物膜吸附/解吸微量重金属无机污染物的过程及影响因素,并对管网中对微量重金属的控制理论与技术进行了展望。The drinking water distribution network is an important part of the water supply system.The growth and shedding of biofilmon the wall of the water supply pipes will affect the quality of the tap water to a certain extent.In recent years,domestic and foreign scholars have found that trace inorganic pollution exists widely in the drinking water distribution system.It is found that most of the inorganic pollutants in the drinking water distribution system accumulate in the tube wall biofilm.When the biofilm state and water quality conditions change,inorganic pollutants will be released into the water,posing a threat to human health.This paper reviewsthe process and influencing factors of the adsorption/desorption of trace heavy metal inorganic pollutants by the tube wall biofilm,and prospects the control theory and technology of trace heavy metals in drinking water distribution system.
