摘要
为了妥善解决城市污泥的处置问题,为污泥的资源化利用提供基础资料,本文应用GC／MS对北京城市污泥中美国EPA优控的6种邻苯二甲酸酯(PAEs)类环境激素进行了研究．结果表明,北京城市干污泥中6种 PAEs的总质量分数wtot在(2．08-5．82)×10-5;各污水厂污泥中PAEs的分布模式相同,峰值都位于DEHP,约占wtot的90％以上,其余PAEs类化合物的质量分数较低．影响城市干污泥中PAEs质量分数的可能因素包括 PAEs的理化性质、生物降解性能、污水及污泥处理工艺及污水中PAEs的来源及质量浓度等．
In order to provide the fundamental data for sludge utilization as fertilizer, six phthalic acid esters （PAEs） which are classified as environmental endocrine disruptors in Beijing sewage sludges were studied with GC-MS. The range of total mass fraction of PAEs in dried sludge was from 2.08 × 10^-5 to 5.82 × 10^-5. The distribution characteristics of PAEs in sewage sludge from five wastewater treatment plants were alike, in which di-2-ethylhexyl phthalate（DEHP） was predominant, accounting for more than 90 percent of total mass fraction of PAEs. The factors affecting the types and mass fractions of PAEs in sewage sludge included physical-chemical properties and biodegradability of PAEs, methods of wastewater and sludge treatment, sources and concentrations of PAEs in wastewater.
