摘 要
城市污泥作为污水处理过程中的必然产物，其处理处置问题已成为全球环境治理的重要议题。随着城市化进程的加速和污水排放量的增加，污泥产量持续攀升，传统处理方式已难以满足环保与资源化需求。本研究旨在探讨城市污泥处理处置技术的优化路径及其资源化利用潜力，以实现环境、经济和社会效益的协同提升。研究综合运用文献分析、实验验证和案例对比等方法，系统评估了多种主流污泥处理技术，包括厌氧消化、好氧发酵、热解气化及建材利用等，并结合实际工程数据对各技术的适用性、经济性和环境影响进行量化分析。结果表明，厌氧消化结合热电联产技术在能源回收方面具有显著优势，而好氧发酵则更适用于有机质含量较高的污泥资源化利用。

Abstract
As an inevitable product in the process of sewage treatment, the treatment and disposal of urban sludge has become an important issue of global environmental governance. With the acceleration of the urbanization process and the increase of sewage discharge, the sludge output continues to rise, and the traditional treatment method has been difficult to meet the needs of environmental protection and resource recovery. This study aims to explore the optimization path of municipal sludge treatment and disposal technology and its recycling potential to realize the synergistic improvement of environmental, economic and social benefits. Using the methods of literature analysis, experimental verification and case comparison, a variety of mainstream sludge treatment technologies, including anaerobic digestion, aerobic fermentation, pyrolysis and gasification and building materials utilization, and quantitatively analyzed the applicability, economy and environmental impact of each technology based with the actual engineering data. The results show that anaerobic digestion combined with cogeneration technology has significant advantages in energy recovery, while aerobic fermentation is more suitable for the resource recycling of sludge with high organic matter content.
