摘要
我国城镇污泥处理处置起步较晚,多元利用途径和产业化推广仍在探索,其中经济性是关系到技术应用路径是否通畅,技术体系能否有效落地的重要因素。“厌氧消化+土地利用”是我国目前城镇污泥处理处置主流技术路线之一。聚焦“常规厌氧消化+土地利用”和“高级厌氧消化+土地利用”2条主流技术路线,基于全流程运行成本统一核算方法,分析不同泥质或技术条件下的经济性特征和变化规律;探讨经济性和技术实施如何相互影响,并通过经济性分析对“厌氧消化+土地利用”技术路线的应用推广提出优化建议。研究结果将为城镇污泥处理处置顶层设计和技术路线选择提供依据,为工程运营单位评估和提升运行水平提供参考,为城镇污泥无害化处理与资源化利用的推广落地提供支撑。
The treatment and disposal of municipal sewage sludge started late in China,and yet multiple utilization ways and industrialization promotion are still being explored,of which economy is an important factor related to the success of the technical application path and realization of the technical system.“Anaerobic digestion+land use”is one of the mainstream treatment and disposal technical routes of municipal sewage sludge in China.Focusing on“traditional anaerobic digestion+land use”and“advanced anaerobic digestion+land use”,based on the unified accounting method of the whole process operation cost,economic efficiency,and change rules under different sludge characteristics or technical conditions were analyzed.Besides,this study discussed the interaction between economy and technology implementation and put forward optimization suggestions for the application and promotion of the“anaerobic digestion+land use”technical route through economic analysis.This study can provide a basis for the top-level design and technical route selection of municipal sewage sludge treatment and disposal,provide a reference for project operators to evaluate and improve the operation level,and provide support for the promotion and realization of municipal sewage sludge harmless treatment and resource utilization.
