摘要

摘要: 随着城市化进程的快速推进、排水系统提质增效和“源网厂河一体”全要素水环境治理工作的开展，城市多源污泥产量显著增加，科学处理处置面临严峻挑战。分析了不同来源污泥的特性和面临的碳排放挑战，基于双碳目标提出了多源污泥有机质和无机质梯级利用的途径和适用技术，强调通过技术创新实现能耗和物耗的降低、温室气体的有效控制和资源的高效替代，并探讨了系统思维指导下的多元协同模式和减碳策略，包括多源物料协同、上下游协同和跨行业协同，以期在更广泛的范围内实现更深层次的减碳效益。

Abstract: With the rapid advancement of urbanization， the upgrading and optimizing of the drainage system， and the implementation of integrated comprehensive water environment governance， incorporating source control， network systems， treatment plants， and river management， the production of urban multi-source sludge has significantly increased， presenting severe challenges for its scientific treatment and disposal. The paper delves into the characteristics of sludge from various origins， including municipal sewage sludge， pipeline sediments， and riverbed sediments， each with distinct physical and chemical properties. It also examines the carbon emission challenges associated with these different types of sludge. In response to the Dual Carbon goals， the paper proposes tiered utilization pathways for both organic and inorganic components in multi-source sludge. These pathways aim to optimize the use of resources contained within the sludge， turning waste into valuable assets. The emphasis on technological innovation underscores the need to reduce energy consumption and material usage while effectively controlling greenhouse gas emissions. Innovations in sludge treatment technology can lead to more efficient resource substitution， minimizing reliance on non-renewable resources. Additionally，the paper highlights the importance of adopting a systematic approach to address the complexities of sludge management. This involves exploring diversified collaborative models and carbon reduction strategies that go beyond traditional boundaries， including the synergy among multiple materials， upstream-downstream integration， and cross-industry collaboration， aiming to realize deeper carbon emission reduction across a broader scope.
