摘　　要：乙醛废水成分复杂,还有较多的有机污染物,直接排放将对水体造成严重的污染。因此,需对乙醛废水进行处理。水质常规监测是废水处理及水环境管理必不可少的一部分。针对乙醛废水中有机污染物组成进行了全面分析,认为选用液-液萃取与吹扫捕集两种预处理模式结合检测乙醛废水的特征污染物较好。研究成果可做为乙醛废水水质监测的参考方法。Acetaldehyde wastewater has complex composition with more organic pollutants.Direct discharge will cause serious pollution to water body.Therefore,it is necessary to treat acetaldehyde wastewater.Routine monitoring of water quality is an indispensable part of wastewater treatment and water environment management.The composition of organic pollutants in acetaldehyde wastewater was comprehensively analyzed.It is considered that the combination of liquid-liquid extraction and purge-trap pretreatment modes are better to detect the characteristic pollutants in acetaldehyde wastewater.The research results can be used as a reference method for monitoring the quality of acetaldehyde wastewater.
