污水处理厂产生的污泥中普遍吸附着表面活性剂、药物及个人护理品、雌激素、全氟化合物、邻苯二甲酸酯和纳米材料等新兴污染物。新兴污染物的存在必然会对以厌氧发酵及土地利用为代表的污泥资源化利用过程产生影响，其自身也会发生降解。本文介绍了上述6种典型新兴污染物在污泥中的污染现状，分析了其对污泥厌氧发酵产生的影响，并阐述了其产生影响的相关机理。同时讨论了新兴污染物在污泥厌氧发酵过程中的降解情况，发现新兴污染物的降解受其物理化学特性、生物降解难易程度、自身浓度、共代谢效应等影响。最后，对今后污泥中新兴污染物研究的发展方向进行了展望，指出今后应重点探究新兴污染物在污泥厌氧发酵过程中的降解方法、途径及机理，以利于后续污泥的土地资源化利用。

Emerging contaminants(ECs),such as surfactant,personal care products(PPCPs), estrogens,perfluorinated compounds(PFCs),phthalates and nanoparticles(NPs)are commonly absorbed in the sludge from wastewater treatment plants(WWTPs). Occurrence of ECs could affect anaerobic digestion (AD)and land application of sludge,and also itself could be degraded. In the present paper,the effects of six kinds of typical ECs on sludge anaerobic digestion were analyzed and their mechanisms were proposed. Meanwhile,degradation of ECs during sludge anaerobic fermentation was discussed. Their biodegradation was influenced by physico-chemical properties,biodegradability, concentration and co-metabolism. Future research on ECs in the sludge should be focused on degradation methods,pathways and mechanisms of ECs in order to benefit land application of sludge.
