Description
技术领域technical field
本发明属于建筑固废资源化利用、建筑材料领域,涉及一种建筑固废精品化处理工艺。The invention belongs to the field of resource utilization of building solid waste and building materials, and relates to a high-quality treatment process of building solid waste.
背景技术Background technique
随着我国基础设施建设的大力发展,老旧建筑、道路等拆迁改造,住宅、市政设施等大规模新建,产生了巨量的建筑固废,据统计,我国目前年产量约在20亿吨左右,储量建筑固废约在200亿吨,造成了环境、土地、空气、水资源的严重污染。目前我国建筑固废大多以填埋为主,无法从根本上解决建筑固废的处理问题,浪费了大量的土地资源。With the vigorous development of my country's infrastructure construction, old buildings, roads, etc. are demolished and rebuilt, and large-scale construction of houses and municipal facilities has produced a huge amount of construction solid waste. According to statistics, my country's current annual output is about 2 billion tons. , The reserve of construction solid waste is about 20 billion tons, causing serious pollution of the environment, land, air, and water resources. At present, most of my country's construction solid waste is landfilled, which cannot fundamentally solve the problem of construction solid waste disposal, wasting a lot of land resources.
我国建筑拆除现场不对建筑固废进行系统分类,大大增大了建筑固废资源化利用的难度。目前建筑固废处理仅仅实现了简单的破碎筛分,一般包含破碎、磁选、筛分等工序。根据建筑固废类型、再生产品需求的不同,还无针对混杂建筑固废资源化系统处置的成熟工艺技术,普遍存在缺乏系统除杂手段、处理效率低、产品质量不稳定等问题。目前一般建筑固废处理为再生骨料,仅仅是用在再生砖、再生砌块等低附加值的产品上,使资源化利用企业难以产生利润。同时产生的再生骨料压碎指标、含杂、表观密度等也难以达到国标要求,更难以在混凝土中得以应用。my country's construction demolition sites do not systematically classify construction solid waste, which greatly increases the difficulty of resource utilization of construction solid waste. At present, construction solid waste treatment only realizes simple crushing and screening, which generally includes crushing, magnetic separation, screening and other processes. According to the different types of construction solid waste and the demand for recycled products, there is no mature process technology for the systematic disposal of mixed construction solid waste, and there are generally problems such as lack of systematic removal methods, low treatment efficiency, and unstable product quality. At present, general construction solid waste is treated as recycled aggregate, which is only used in low value-added products such as recycled bricks and recycled blocks, making it difficult for resource utilization enterprises to generate profits. At the same time, the crushing index, impurity content, and apparent density of the recycled aggregate produced are also difficult to meet the national standard requirements, and it is even more difficult to be applied in concrete.
