摘　　要：总结了近年来利用强化混凝去除水源水中天然有机物的研究 ,重点讨论了其作用机理和主要影响因素。水源水中天然有机物的含量和成分会因水源地和时间的不同而存在差异 ,对水源水中天然有机物的了解是保证强化混凝效果的基本前提。不同混凝条件下 ,强化混凝的主导作用机理不同。铁盐混凝剂、较低pH值。The research concerning the control of natural organic matter(NOM) by enhanced coagulation is summarized in the paper, and its mechanisms and operational factors are primarily discussed. The characteristics of NOM can vary with location and throughout the year, and a good knowledge of it can be helpful to ensuring a good enhanced coagulation efficiency. The primary mechanism of enhanced coagulation can vary under different operational factors. Fe(Ⅲ) coagulant, low pH values, high coagulant dosage and cations can be helpful to more effective control of NOM in drinking water.
