摘　　要：壬基酚聚氧乙烯醚 ( NPn EO)是广泛使用的表面活性剂 ,在污水处理厂中会降解为具有内分泌干扰效应的短链产物和最终产物壬基酚 ( NP)。剩余污泥是其进入环境的重要途径。介绍了 NP和短链 NPn EO在污泥中的存在情况、污泥处理过程对其存在的影响。Nonylphenol ethoxylates, widely used in commercial and household detergents, can degrade during wastewater treatment process to more toxic and estrogenic compounds, which include nonylphenol, nonylphenol mono and di ethoxylates. Due to their high hydrophobicity, they can absorb into sludge and come into soil with sludge disposal progress. Their occurrence in sludge and soil, transportation during sludge treatment and degradation in soil are reviewed.
