摘要: 随着我国城镇污水处理厂污泥产量的不断增加,污泥的处理处置已成为人们关注的热点问题。实现污泥减量化、稳定化、无害化与资源化是污泥处理处置的终极目标。分析了市政污泥脱水的主要影响因素,概述了目前广泛采用的市政污泥脱水预处理技术,详细介绍了生物淋滤技术及其对污泥脱水性能的影响,并对存在的问题及发展方向进行探讨。

关键词: 污泥脱水, 生物淋滤, 污泥调理, 预处理

Abstract: With the continual increase of sludge yield in urban sewage treatment plants in China, the sludge treatment has become a hot spot problem concerned by people. The ultimate aim of sludge treatment and disposal in the future is to achieve the reduction, stabilization, detoxification and recycling of sludge. In this review, the main influencing factors of municipal sludge dewatering are analyzed and the widely used pretreatment technologies of municipal slu-dge dewatering summarized. Furthermore, the bioleaching technique and its influence on sludge dewatering capabili-ty are introduced in detail, and its problems and developing direction are also discussed.

Key words: sludge dewatering, bioleaching, sludge conditioning, pretreatment
