摘要

摘要: 随着我国污水处理能力的增加，污水处理过程中产生的剩余污泥量也与日剧增。污泥处理问题亟待解决，其中污泥脱水是关键环节。污泥高含水率会为后续处理带来诸多处理难题，增加处理成本。综述了污泥脱水技术，涵盖机械脱水和污泥干化等方式，并对其在实际应用中的优劣势进行了分析。对影响污泥脱水性能的因素进行了系统研究，明确胞外聚合物（EPS）、胶体颗粒物等多种因素的作用机制。此外，全面介绍物理、化学和生物调理方法及其效果，并对每种调理脱水方式列举应用案例，总结了污泥脱水效果，为污泥处理提供参考。在此基础上，展望了污泥脱水实现资源化和低碳化的未来方向，主要包括技术创新以及协同处理等，旨在促进污泥处理领域的可持续发展。

Abstract: With the increase in China's sewage treatment capacity， the amount of residue sludge generated during the wastewater treatment process has also been increasing gradually. The issue of sludge treatment urgently needs to be addressed， and sludge dewatering is a key link. The high water content in sludge brings many difficulties to subsequent treatment and increases treatment costs. This paper provides a comprehensive overview of sludge dewatering technologies， including mechanical dewatering and sludge drying， while analyzing the advantages and disadvantages in practical applications. A systematic study was conducted to investigate the factors affecting sludge dewatering performance， clarifying the action mechanisms of various factors， including extracellular polymeric substances （EPS） and colloidal particles. In addition， the physical， chemical， and biological conditioning methods and their effects were comprehensively introduced. For each method， multiple application methods and their effects were listed， providing a comprehensive reference for sludge treatment. On this basis， future directions for sludge dewatering were prospected with a focus on resource utilization and low-carbonization， mainly including technological innovation and collaborative treatment， aiming to provide a reference for sludge treatment and promote the sustainable development in sludge treatment and disposal.
