Abstract

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.
- municipal sewage sludge,
- treatment and disposal,
- carbon emission,
- energy saving and consumption reduction,
- energy and resource recovery
