碳中和目标下污泥处理技术的研究进展与展望

Research Progress and Prospects of Sludge Treatment Technology under the Goal of Carbon Neutrality

碳中和目标下,碳减排为废液活性污泥(WAS)处理技术和程序的评估提供了新的限制。文章概述了WAS处理的当前研究和开发工作,重点关注WAS作为污染物和资源的双重属性。首先,文章研究了重金属、微(纳米)塑料或其他新型塑料对WAS提出的技术要求;其次,在碳减排方面,讨论了广泛部署的WAS处理技术的应用和局限性,并基于碳中和目标,从污染物去除效率、增强方法、碳排放、资源回收等角度,全面探讨了厌氧共消化和共热解技术;最后,为未来的技术进步和工程创新提出了一条可行的WAS处理新途径。

Under the goal of carbon neutrality,carbon abatement imposes new constraints on the evaluation of waste activated sludge(WAS)treatment technologies and procedures.This paper presents an overview of current research and development efforts in WAS treatment,with a specific focus on the dual nature of WAS as both a pollutant and a valuable resource.Firstly,this paper examines the technical requirements pertaining to heavy metals,micro(nano)plastics or other emerging plastics in relation to WAS.Additionally,this paper discusses the application and limitations of widely deployed WAS treatment technologies from a carbon reduction perspective,and taking into account the goal of carbon neutrality,comprehensively explores anaerobic co-digestion and co-pyrolysis technologies in terms of pollutant removal efficiency,enhancement methods,carbon emissions and resource recovery.Finally,this paper proposes a feasible novel approach for future technological advancements and engineering innovations in WAS treatment.
