摘要

摘要: 剩余污泥的处理处置已成为污水处理厂面临的一个重大挑战。厌氧消化是一种常用的污泥处理方法。传统的污泥厌氧消化存在许多不足,而污泥热碱处理能使之改善。综述了近年来污泥热碱处理的研究,从热碱处理的机理出发,总结了热碱处理对污泥性质和厌氧消化的影响,分析了影响污泥热碱处理效果的因素,并通过能耗分析讨论了热碱处理强化污泥厌氧消化的可行性,最后指出污泥热碱处理及其强化污泥厌氧消化存在的问题,并提出了建议和展望。

Abstract: Huge amounts of sludge are produced in wastewater treatment, and the treatment and disposal of sewage sludge had become a rising challenge for the wastewater plant. Anaerobic digestion is a traditional method for sewage sludge treatment, which has some shortages. Recent research showed that thermal-alkaline pretreatment could enhance the anaerobic digestion of sewage sludge. In this study, the research progress of thermal-alkaline pretreatment of sludge was thoroughly reviewed, including the mechanism of thermal-alkaline pretreatment, the impact of thermal-alkaline pretreatment on the sludge properties and anaerobic digestion and the influencing factors. And the feasibility of thermal-alkaline pretreatment for enhancing anaerobic digestion of sewage sludge was discussed through energy consumption analysis. Finally, the enhancement of thermal-alkaline pretreatment on anaerobic digestion and its prospects and problems were also discussed.
