摘　　要：为提高污泥资源化利用效率,实现碳达峰目标,本文综述了城镇污水处理厂污泥资源化利用现状,重点分析污泥生产有机肥、生产沼气、制备生物炭、回收碳氮磷、生产建筑材料等资源化利用技术。对于有毒有害物质含量低的污泥,可以用来生产有机肥或者沼气;对于不适合农用的污泥,可以用来生产建筑材料;有条件的地区,可以开展污泥制备生物炭、回收碳氮磷等技术的研究与实际应用。各污水处理厂需因地制宜、分类施策,科学、有效的处理和处置污泥。In order to improve the efficiency of sludge resource utilization and achieve the goal of carbon peak,the present situation of sludge resource utilization in urban sewage treatment plants was reviewed,and the technologies of sludge utilization as organic fertilizer,biogas recovery,preparation of biochar,recovery of carbon,nitrogen and phosphorus,and production of building materials were also analyzed.Sludge with low toxic and harmful substance can be used to produce organic fertilizer or biogas.Sludge which is not suitable for agricultural can be used to produce building materials.If conditions permit,research and practical application of technologies such as biochar preparation from sludge and recovery of carbon nitrogen and phosphorus can be carried out.Sewage treatment plants need to take measures according to local condition,in order to treat and dispose of sludge scientifically and effectively.
