摘要

摘要: 城镇污水污泥富集了污水中的资源物质与污染物质，污泥处理处置作为污水处理终端治污环节，既贡献了不可忽视的碳排放量，也具有可观的资源和能源回收潜力。系统分析了污泥处理处置各工艺单元的碳排放构成和主流技术路线碳排放特点，从逸散性温室气体减排、节能降耗、能源资源回收利用等角度出发，探讨厌氧消化+土地利用、好氧发酵+土地利用、焚烧+建材利用3条技术路线的碳减排技术研究与应用进展，提出3项具有应用前景的新型能源资源回收利用技术，最后对我国未来污泥处理处置的发展方向进行了展望。

Abstract: Municipal sewage sludge enriches resources and pollutants during the sewage treatment process. As the final pollution control stage of sewage treatment， sludge treatment and disposal not only contribute to non-negligible carbon emissions， but also hold considerable potential for resource and energy recovery. This study systematically analyzed the the composition of carbon emissions from process units and the carbon emission characteristics of mainstream technical routes for sludge treatment and disposal. From the perspectives of greenhouse gas emission reduction， energy saving and consumption reduction， energy and resource recovery， etc.， this study discussed the carbon emission reduction technologies for the 3 mainstream technical routes including anaerobic digestion + land use， aerobic fermentation + land use， and incineration + building material utilization. It also summarized new energy and resource utilization technologies with application prospects. In the end， this study put forward some future development directions for sludge treatment and disposal.
