煤基固废生态化利用研究进展

Research Progress on Ecological Utilization of Coal-based Solid Waste

煤基固废大量堆存的现状不仅是对资源本身的浪费,而且会对周边环境造成污染,从而对人类生存环境造成威胁。在环保政策的压力下它的处置已成为倒逼企业运行的重要压力之一。以产生量大、利用受限、污染严重的煤基工业固废为切入点,以实现煤基固废高值化、规模化消纳和资源化利用为目标,综述了煤基固废产生、性质及其综合利用现状,重点阐述了煤基固废在土壤改良、共堆肥、环境污染修复等生态利用方面的研究现状,对其生态化利用潜力进行了分析,并对煤基固废未来在环保材料及矿区生态修复治理技术等方面的应用前景进行了展望。

The current situation of large amount of coal-based solid waste stockpiling is not only a waste of resources,but also a pollution to the surrounding environment,thus threatening the human living environment.Under the pressure of environmental protection policy,its disposal has become one of the important pressures to force enterprises to operate.The article summarizes the generation,properties and comprehensive utilization status of coal-based solid wastes,focusing on the research status of soil improvement,co-composting,environmental pollution remediation and other ecological utilization of coal-based solid wastes.The potential of ecological utilization of coal-based solid waste is analyzed,and the application prospect of coal-based solid waste in environmental protection materials and ecological restoration technology in mining area is prospected.
