摘 要:【目的】近十年,河北省大型建设项目不断开展,建筑废弃物的数量也不断上升,寻找行之有效的建筑废弃物资源化方式,提高建筑废弃物资源化利用率,是建筑废弃物处理的重点。【方法】基于新《固废法》和河北省的实际情况,提出三种具有前瞻性的建筑废弃物资源化综合模式。通过模糊层次综合评价法对三种模式进行评价。【结果】现场破碎集中生产路边石、行道砖、碎石桩、预制砂浆、再生混凝土模式是河北省效果最优的建筑废弃物资源化模式。【结论】河北省政府应当通过财政、税收和投资等手段来推动建筑废弃物资源化利用。

Abstract:[Purposes] In recent decade, large-scale construction projects in Hebei Province have been carried out continuously, and the output of construction waste has also been rising. It is the focus of construction waste treatment to find effective ways of construction waste recycling and to improve the efficiency of construction waste recycling. [Methods] Based on the new solid waste Law and the actual situation of Hebei Province, the researchers put forward three forward-looking comprehensive models of construction waste recycling. The three models are evaluated by the fuzzy level comprehensive evaluation method. [Findings] The mode of centralized production of kerb, road brick, gravel pile, precast mortar and reclaimed concrete has the best effect in Hebei Province. [Conclusions] The Hebei provincial government should pay more attention to the support for the utilization of construction waste resources, and promote the utilization through economic levers such as finance, tax revenue and investment.

近年来,河北各地实施基础设施建设,推进各类民生工程,促进了经济发展,同时也产生了大量建筑废弃物。以目前粗放式的处理方式,垃圾填埋场的承载能力将不堪重负,环境将遭受严重损害,垃圾围城现象会日益严重。河北省住建厅等五部门印发的《关于加强建筑废弃物管理和资源化利用工作的指导意见》指出,到2025年建筑废弃物资源化利用率将达到50%以上。因此,在吸取我国现行建筑废弃物资源化经验及以往学者研究成果的基础上,如何构建一个包含收集、运输、处理、再利用各环节的建筑废弃物处理产业链,进而实现建筑废弃物资源化利用,是当下建筑废弃物资源化重点研究的课题。……
