摘　　要：城市污泥是污水处理厂处理后的剩余产物,其富集了未被处理掉的污染物,如重金属、病原微生物、寄生虫等有害物质,同时也含有巨大的资源化再利用潜力,如有机物、氮、磷、钾等资源物质,不仅需要做好污染物的处置工作,防控污泥潜在风险,还需充分利用城市污泥中的二次资源。文章阐述了我国城市污泥处置现状,从土地利用、能源利用、建筑工艺与环保材料等方面对城市污泥处置方法进行了论述,对城市污泥转化成生物炭、有机肥、合成燃料等高附加值产品的利用途径进行了分析,并对城市污泥处理、处置技术的前景进行了展望,旨在推进相关研究,提高城市污泥资源化利用水平。Urban sludge is residual product of wastewater treatment plants,is enriched with pollutants that are not treated,such as heavy metals,pathogenic microorganisms,parasites,and other harmful substances.It also contains a huge potential for resource recycling,such as organic matter,nitrogen,phosphorus,potassium,and other resource materials.It is necessary to not only properly dispose of pollutants and control the potential risks of sludge but also to fully utilize the secondary resources in urban sludge.In this paper,the current situation of urban sludge disposal in China was introduced,the methods of urban sludge disposal were discussed from the aspects of land use,energy utilization,construction technology,and environmental protection materials,the utilization pathways of transforming urban sludge into high-value products such as biochar,organic fertilizer,and synthetic fuel were analyzed,and the prospects of urban sludge treatment and disposal technology were put forward,aiming to promote related research and improve the level of resource utilization of urban sludge.
