河北省建筑废弃物资源化模式评价研究

An Approach to the Construction Waste Recycling in Hebei Province

【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。

[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 con-struction waste treatment to find effective ways of construction waste recycling and to improve the effi-ciency of construction waste recycling.[Methods]Based on the new solid waste Law and the actual situa-tion of Hebei Province,the researchers put forward three forward-looking comprehensive models of con-struction 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 gov-ernment 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.
