摘要
厌氧发酵产氢是污泥资源化利用的一种重要途径,然而污水处理过程中新兴污染会通过各种途径转移至污泥中,影响污泥的后续处理。总结了抗生素、表面活性剂、工业添加剂、溴系阻燃剂(BFR)4种新兴污染物在污泥中的污染现状,阐述了新兴污染物对污泥发酵产氢的影响,并揭示了相关作用机制。同时,分析了新兴污染物在污泥发酵体系的降解转化规律。最后,对今后污泥中新兴污染物的研究做了展望,以利于污泥的资源化利用。
Hydrogen production from anaerobic fermentation is an important way for sludge resource utilization.However,the emerging contaminants will be transferred to sludge through various ways in the process of sewage treatment,which will affect the subsequent treatment of sludge.This paper summarized the pollution status of four emerging contaminants in sludge,including antibiotics,surfactants,industrial additives and brominated flame retardants(BFR),and expounded the impact of these emerging contaminants on the hydrogen production from sludge fermentation,and revealed the relevant mechanisms.Meanwhile,the degradation and transformation of the emerging contaminants in the sludge fermentation system were analyzed.Finally,the future research of the emerging contaminants in sludge was prospected,in order to facilitate the utilization of sludge resources.
