摘　　要： 多环麝香在日常生活中被广泛使用,在生产和使用过程中会经过污水处理系统而进入环境中。研究了日用化妆品生产工厂排放的多环麝香在污水处理系统中污水和污泥的污染特征。在大型日用化妆品生产工厂污水处理厂的污水和污泥中均检测出较高浓度的多环麝香,HHCB和AHTN是两种主要污染物。其中多环麝香在污水处理系统进水中质量浓度范围为4.7(AHMI)～550μg·L-1(HHCB),出水中质量浓度范围为:低于检测限(AHMI)～32.1μg·L-1(HHCB),污泥(干物质量)中多环麝香的含量范围为1.78(AHMI)～566mg·kg-1(HHCB)。污水处理系统污水中多环麝香的去除效率非常高,达到了90%以上,然而,污泥中却富集了大量的多环麝香,表明污水中的多环麝香很大一部分转移到了污泥中,从而可能成为环境中一种潜在的多环麝香污染源。 Polycyclic musks have been confirmed they could be discharged into the environment from wastewater treatment plant duo to extensive use in daily life. In present study, concentration and distribution of polycyclic musks in the wastewater and sludge from a cosmetic plant were obtained. High concentrations of polycyclic musks have been detected both in the wastewater and sludge, and HHCB and AHTN were the most dominating contaminations. Concentrations of individual polycyclic musk ranged from 4.7 （AHMI）～550 μg·L-1 （HHCB） in influence, however, concentration from below detection limit for AHMI to 32.1 μg·L-1 for HHCB were determined in effluence of the wastewater, and 1.78～566 mg·kg-1 were found in the sludge （dry weight）. Despite high remove efficiency for the polycyclic musks which could reach 〉 90% was obtained in the wastewater plant, high concentrations of polycyclic musks in the sludge indicated they could been transferred to the sludge from the wastewater during wastewater treatment plant. Therefore, the sludge will be a potential source of polycyclic musks.
