摘　　要：三氯乙醛是饮用水中广泛存在的消毒副产物,其在水中含量仅次于三卤甲烷和卤乙酸,控制三氯乙醛的生成十分必要.本文阐述了三氯乙醛的生成特性、三氯乙醛的不同的检测方法、三氯乙醛前体物的表征方法、三氯乙醛的控制方法,为今后净水工艺中控制三氯乙醛的生成提供参考依据.Trichloroacetaldehyde is a widely existed disinfection by-product in drinking water,whose content in water is only next to trihalomethanes and haloacetic acids,so it is very necessary to control the formation of trichloroacetaldehyde.In this paper,the formation characteristics of trichloroacetaldehyde,different detection methods of trichloroacetaldehyde,characterization methods of trichloroacetaldehyde precursors,and control methods of trichloroacetaldehyde in were described,which provided a theoretical basis for controlling the formation of trichloroacetaldehyde in the water purification process in the future.
