摘要

现在,在大规模住宅和土地开发的土壤挖掘过程中,经常发现过去埋在地下的废物。如果没有对废物进行适当的环境处理,挖掘过程就不能继续进行,因此应制定一项行动计划,以环境和经济上可行的方式处理废物。研究了垃圾表观密度与垃圾处理成本估算的基础——体积换算系数之间的关系。从填埋场的10个采样点对垃圾进行采样,分析其物理特性,并评估混合和分类垃圾的表观密度。应用经验公式和本文提出的公式,与自卸车和挖掘机在现场直接测量的体积换算系数进行了比较。显然,由经验公式得出的体积换算系数与我们提出的公式和现场实测的体积换算系数之间存在密切的关系。

A Study on Correlation between Volume Conversion Factor and Apparent Density of Wastes Buried in Landfill
It is now common to find the wastes buried in the past during the excavation process of soil for large scale housing and land development. Without proper treatment of the wastes environmentally, the excavation process is no longer able to proceed, and an action plan should be provided to treat the wastes with environmental and economic viability. In the study, the relationship between the apparent density of the wastes and the volume conversion factor, which is the basis in the estimation of waste treatment cost was investigated. From 10 sampling points of a landfill site, wastes were sampled, analyzed for physical characteristics, and the apparent density of mixed and sorted waste was assessed. Applying the empirical formula, and the formula we suggested here, the volume conversion factors were compared with that measured directly in the field using dump truck and excavator. Obviously there was a close relationship among the volume conversion factors resulting from the empirical formula, the formula we suggested and that measured in the field.
