城市污水处理厂中多环麝香的迁移转化途径研究

采用GC-MS法对上海某污水处理厂各处理单元的多环麝香分布状况进行检测,探讨了城市污水处理过程中多环麝香的迁移转化途径。结果表明,城市污水处理厂进水中佳乐麝香（HHCB）和吐纳麝香（AHTN）的平均浓度分别为1.269μg/L和0.107μg/L,出水中平均浓度分别为0.578μg/L和0.056μg/L,总去除率分别为54.5%和47.7%。污泥中多环麝香的含量较高,HHCB和AHTN的浓度范围分别为2.909~10.965mg/kg（干污泥）和0.573~2.459mg/kg（干污泥）。多环麝香的迁移与去除途径包括：污泥的吸附作用、生物降解作用、曝气挥发损失以及随处理出水的排放。

Study on Translation and Conversion Behavior of Polycyclic Musks in Municipal Wastewater Treatment

The distribution of polycyclic musks in the different units of a municipal wastewater treatment plant was determined by GC-MS.The translation and conversion of the musks in the municipal wastewater treatment course were discussed.The results show that the average concentrations of HHCB and AHTN in the influent of the plant were 1.269 μg/L and 0.107 μg/L,while in the effluent they were found to be 0.578 μg/L and 0.056 μg/L respectively.The removal efficiencies were 54.5% and 47.7% respectively.The polycyclic musks transference ways and removal routes from wastewater treatment system can be considered to involved the adsorption to sludge,the biodegradation in aerated tank,the loss of volatilization and the discharge with the effluent.
