摘要
地下空间开挖产生大量的工程弃土成为城市发展过程中亟待解决的重要环境问题,对其资源利用是未来的发展趋势。当前,进行泥沙分离是工程弃土的主要资源利用方式,分离后沙石直接作为骨料利用,而剩余的泥渣中含有丰富的黏土资源,却没有得到很好利用。从技术原理、工艺和质量保证措施提出以泥渣和有机废弃物为原料再生种植土的新思路,不仅能够有效解决工程弃土和有机废弃物的处置难题,还能为我国的种植土资源提供新的补充来源,在高质量绿化种植土生产和耕地占补平衡均有广阔的应用前景。
The excavation of underground space brings a large amount of engineering waste soil, which has become an important environmental problem to be solved for urban development. The eruse of the soil is the need for the future developmen t trend. At present, sediment separation is the main resource ultiization mode of soil. After separation, sand and stone are deicrtly used as aggregate, while the remaining mud containing abundantc lay has not been well utilized. From the technical principle , technology and quality assurance measures, this paper puts foarrwd a new idea of regenerating planting soil with sludge resocuers and organic waste. It can not only effectively solve the dispaols problems of soil and organic waste, but also provide a n ew supplementary source for planting soil in China. It has broadp palication prospects in high-quality greening soil production nad cultivated land requisition-compensation balance.
