摘要
环境保护部和国土资源部发布的《全国土壤污染状况调查公报》显示,中国重金属污染土壤已经对生态环境和人体健康造成严重的危害,必须采取有效的措施对污染土壤进行修复与改良处理。利用钢渣具有的高碱性、多孔性和胶凝性制备钢渣基修复材料用于土壤修复与改良成为重要途径之一。基于钢渣的物化性质,对钢渣基修复材料作为土壤修复与改良的药剂进行具体分析;阐述钢渣基修复材料在土壤修复与改良中的工程应用,并就目前钢渣基修复材料的技术发展进行评述。在此基础上,指出优化钢渣基修复材料性能、拓展其在不同性质土壤的应用,以及结合草坪种植、休闲农业种植、农业景观设计等开发多种钢渣基修复材料,是钢渣修复与改良土壤未来的主要发展方向。
According to the National Soil Pollution Survey Bulletin released by the Ministry of Environmental Protection and the Ministry of Land and Resources,heavy metal contaminated soil in China has caused serious harm to ecological environment and people′s health,effective measures must be taken to repair and improve contaminated soil.Steel slag-based remediation materials are prepared by utilizing the high alkaline,porous and cementitious properties of steel slag for soil remediation and improvement,becoming one of the important ways.The physical and chemical properties of steel slag are firstly briefly introduced,steel slag-based remediation materials as soil remediation and improvement agents are specifically analyzed.Engineering application of steel slag-based remediation materials in soil remediation and improvement are pointed out respectively.Then,the development trend of steel slag-based remediation materials is reviewed.Eventually,it is proposed to optimize the properties of steel slag-based remediation materials and expand their applications in soils with different properties,and combined with lawn planting,leisure agriculture planting,agricultural landscape design and other development of a variety of steel slag-based restoration materials,which will be the main development directions of steel slag used for soil remediation and improvement in the future.
