摘　　要：饮用水中消毒副产物(DBPs)对人体健康构成极大威胁,明确水源水中有机物的特性及对DBPs生成的影响,是实现DBPs有效源头控制的关键环节。研究探讨了上海某水库水源水中有机物不同组分与消毒副产物生成潜能之间的关系,为水处理工艺及饮用水安全保障技术研究提供基础性数据。结果表明,水样中亲水性有机物比例占到60%左右;各组分的相对分子质量分布情况以小于1 000的小分子为主;加强消毒前水处理工艺对亲水性和小分子有机物的去除,可以有效控制DBPs的生成。Disinfection by-products（DBPs） make a big threat to human health,definiting the characteristics of organic matter in raw water and its influence on the formation of DBPs is a key link of source control of DBPs.The article did some research on the relationship between di-fferent components of natural organic matter and disinfection by-products formation potential in a reservoir water source of Shanghai,so as to provide basic data for water treatment technology and drinking water safety technology research.Results showed：the hydrophilic organic matter in water accounted for about 60% of total organic matter;the priority component of the molecular weight distributions was mainly composed of molecules with less than 1 000 dalton;enhancing the removal of hydrophilic and small molecular organic matter before disinfection process would prevent DBPs formation effectively.
