摘　　要：以两种典型的多环麝香———佳乐麝香(HHCB)和吐纳麝香(AHTN)为目标物,对其在北京市3个污水处理厂工艺流程中的分布、迁移进行了研究。结果表明,HHCB和AHTN在进水中的浓度分别为(1 251.4～3 003.8)和(111.9～435.4)ng/L,在出水中的浓度分别为(457.2～729.9)和(35.5～190.9)ng/L,平均去除率分别为62.2%和53.1%。污泥中HHCB和AHTN的含量分别为(2.5～17.0)和(0.7～13.9)μg/g。生物处理阶段是目标物从污水中去除的主要阶段,其去除机理主要是污泥的吸附作用。因此,应关注污水处理厂麝香排放可能带来的水环境风险,尤其是对剩余污泥中该类物质的有效削减应引起足够的重视。The distribution and migration of two typical polyeyelic musks, namely galaxolide （ HHCB） and tonalide （AHTN） were investigated in the processes of three sewage treatment plants （STPs） in Beijing, China. The results show that HHCB and AHTN are 1 251.4 to 3 003.8 ng/L and 111.9 to 435.4 ng/L in the influent, and 457.2 to 729.9 ng/L and 35.5 to 190.9 ng/L in the effluent respectively. The average removal rates of HHCB and AHTN are 62.2% and 53. 1% respectively. HHCB and AHTN in the sludge are 2.5 to 17.0μg/g and 0.7 to 13.9 μg/g respectively. The polyeyclic musks are removed mainly in biological treatment stage. The mechanism for their removal is basically adsorption to sludge. The potential environmental risk caused by the musk discharge from STPs as well as the reduction of the compounds in the excess sludge should be paid attention to.
