| 摘 要： | 原水氯消毒过程中,氯会与水中的天然有机物(NOM)反应,生成三卤甲烷、卤乙酸等消毒副产物(DBPs).为了选择有效的饮用水净化工艺,控制消毒副产物的生成,研究天然有机物的化学特性及与消毒副产物的关系,是十分必要的.在总结NOM相似组分化学分离方法的基础上,概括了不同水源中NOM及各组分溶解性有机砌(DOC)的含量,对消毒副产物的贡献,化学组成以及可能生成DBPs的化学结构.不同水源中NOM及各组分DOC含量不同,相同组分对消毒副产物的贡献也有很大的差别,且NOM各组分的化学组成有一定的重叠,对生成DBPs的化学结构需继续研究.

| Abstract: | Disinfection by-products (DBP) such as trihalomethane and haloacetic acid are formed when natural organic matter (NOM) in water reacts with chlorine. In order to choose effective technics to control DBPs, it is necessary to investigate the chemical characteristic of NOM and its relationship with DBPs. Based on the summarizing of the chemical isolation methods of NOM, the content of dissolved organic carbon(DOC), the contribution to DBPs, the chemical constitutes and the possible structure to form DBPs of NO... |
