摘要
垃圾填埋场开采和可回收土地资源的资源化利用、矿化垃圾的无害化、资源化,具有显著的经济社会效益.归纳了国内外垃圾填埋场管理过程中面对的痛点问题,并着重分析了典型填埋场治理工程案例,明确了原料回收潜力评估、经济效益评估和生命周期评价等开采前预调研工作的重要性;基于矿化垃圾综合资源化利用的思路,重点阐述了当前垃圾填埋场矿化垃圾物理特性、重金属含量、热值和营养元素等物化特性.总结了目前较为成熟的资源化利用方案,包括腐殖土再利用技术及可燃组分热处理技术,为大型垃圾填埋场的施工开采和资源化利用提供了思路.
Abstract
The landfill mining and resource utilization of recyclable land resources,harmless and recycling of mineralized waste in landfill has significant economic and social benefits.The pain points in landfill management at home and abroad were comprehensively reviewed,with a keen focus on analyzing exemplar landfill treatment projects.It underscored the vital importance of pre-mining research,such as encompassing assessments of raw material recovery potential,economic viability evaluation and life cycle assessment.Based on the concept of comprehensive resource utilization of mineralized waste,the physical characteristics,heavy metal content,calorific value,and nutrient components of the mineralized waste in landfills were mainly described.Moreover,the mature resource utilization scheme was summarized,including humus reclamation technology and the thermal treatment of combustible components,thereby offering insights for the construction,excavation,and resource-efficient exploitation of large-scale landfills.
