摘　　要：市政污泥是城市污水处理过程中产生的由无机物质和有机物质组成的复杂残余物。多环芳烃(PAHs)作为一类持久性有机污染物,广泛存在于世界各地的市政污泥中,具有稳定性强、不易降解和环境风险高的特点,能够对生态环境和人体健康构成威胁。因此,对市政污泥中PAHs的去除研究已经受到国内外学者的广泛关注。文章综述了市政污泥中PAHs的来源、国内外市政污泥的PAHs污染现状和市政污泥中PAHs的去除技术,着重阐述了市政污泥好氧堆肥过程中影响PAHs降解的因素及其去除机理,并对堆肥过程中PAHs的高效去除研究做出展望,为今后的市政污泥堆肥化提供新思路。Municipal sludge is a complex residue composed of inorganic and organic substances produced during the treatment of municipal sewage.Polycyclic aromatic hydrocarbons(PAHs)are an important group of persistent organic pollutants,with the characteristics of strong stability,non-degradation and high environmental risk.PAHs widely exist in urban sludge around the world,posing a threat to the ecological environment and human health.The removal of PAHs from municipal sludge has received extensive attention from scholars at home and abroad.In this paper,the sources of PAHs in municipal sludge,the pollution status of PAHs in the municipal sludge worldwide,and the removal technology of PAHs in municipal sludge were reviewed.The factors affecting the degradation of PAHs in the process of aerobic composting of municipal sludge and their removal mechanism were emphatically expounded.In addition,the research on the efficient removal of PAHs in the composting process was prospected.It can provide new ideas for the municipal sludge composting in the future.
