连续1年测定了天津某城市污水处理厂进、出水及污泥中壬基酚聚氧乙烯醚（NPnEO,n为聚合度）及NP的浓度、分布,初步探讨了NPnEO在城市污水处理过程中的迁移转化行为及其随时间的变化趋势。结果表明：城市污水处理厂中进水排水中NPnEO的总浓度、各组分比例变化较大,底泥中NPnEO总浓度相对较稳定,底泥的合理处置,避免二次污染值得深入研究。

The concentrations and distributions of nonylphenol polyethoxylates（NPnEO）and its metabolites were determined in the influents and effluents and sludge from sewage treatment plant of Tianjin.Moreover,the transfer and transformation of NPnEO and its metabolites in the sewage treatment process was discussed primarily,the variation trend of them with time was also discussed.It showed that the concentration and proportion of NPnEO in the influent and effluent varied in the whole year.The concentration of NPnEO in the sediment varied little.It is worth to study that the sediments were treated appropriately.
