摘要
污泥作为污水处理的过程产物,具有“污染”“资源”双重属性,对其开展妥善处置是污水处理减污降碳的重要任务。虽然我国污泥处理经历了“重水轻泥”向“泥水并重”的转变,技术与标准体系发展迅速,但在生态文明建设,碳达峰、碳中和目标的背景下,污泥处理处置仍存在亟待突破的短板弱项。本文梳理了城镇污泥产量和泥质特征、处理处置技术、政策标准体系的发展现状,凝练了污泥处理处置在管理体系、技术标准、路线选择等方面存在的突出问题;结合我国所处的发展阶段和国际发展趋势,提出了“绿色低碳、资源循环、环境友好、因地制宜”的发展理念以及相应的重点举措。研究建议,加强顶层设计,统筹设施规划布局,因地制宜选择处理处置路线;健全污泥处理处置的标准体系,完善价格补贴机制,强化责任分工与监管机制;补短板、强弱项,提升全链条集成水平,形成可推广的技术模式;面向未来实施前沿技术攻关,推动污泥处理处置与资源化技术装备创新升级。
