摘　　要：饮用水管网中的有机污染物种类繁多,直接威胁人类健康。本文简述了给水管网中的4类有机污染物,即原水中带入的有机污染物、管材释放的各种添加剂及其降解产物、管垢释放产物或管垢生物膜和管内水体微生物的代谢产物、消毒副产物。根据现有的研究发现,这4类有机物中,以含量较多的消毒副产物类研究最多,其次是管材释放的各种有机污染物,而含量较低、种类繁多、取样困难的管垢释放产物及生物膜、水体微生物的代谢产物的研究较少。由于给水管网中的有机污染物成分多样,同时在管网这个特殊的水环境中,还会发生迁移、转化等复杂的过程,本文在综述分析以上不同来源的污染物类型的基础上,提出今后的研究可在高毒痕量有机污染物的鉴别、生物膜中有机污染物的释放规律及其代谢产物的定性定量分析、有机污染物的迁移转化等方面展开。This paper discussed four types of organic pollutants,including organic pollutants from raw water,additives and degradation products from pipe leaching,pipe scales releasing or metabolic products from biofilm and microorganism in water,and disinfection by-products. Most current studies focused on disinfection by-products because of their high concentrations,and various organic pollutants from pipe leaching obtained a lot of research attention as well,while organic pollutants from pipe scales releasing or metabolic products from biofilm and microorganism in water were not studies enough due to the low concentration,migration,great variety and difficulties in sampling. This paper pointed out that future research should focus on investigating the identification of high toxic trace organic pollutants,the release performances of different pollutants and the qualitative or quantitative research of degradation products,and the migration and transformation of these organic pollutants.
