粉煤灰、垃圾、污泥土地利用的研究现状与进展

我国在进行开发建设工程中,会产生大量固体废弃物,严重影响了人类生存环境和质量。从粉煤灰、垃圾、污泥的特性入手,分别综述了其在土地利用上的研究现状及进展,指出了单一固体废弃物施用改土的缺点,并认为可以通过多种固体废弃物联合应用改善土壤的性状、提高土壤养分,从而达到减少固体废弃物排放量、保护土地与植被资源的效果。

Research and development of fly ash, garbage, sewage sludge land utilization

Large amounts of solid waste will be made during the development and construction of many projects in China,which leads to severe side effect on the environment and quality of our daily life.Based on the characteristics of fly ash,refuse and sludge,this work gives an review on their current research progress and development for land use,and also indicates the disadvantage of soil improvement applied by only a single solid waste.It has been shown that jointly application by a variety of solid wastes is much better for improvement of the soil traits and soil nutrients,so as to achieve reduction of solid waste emissions and to enhance the protection of land and vegetation resources.
