GOALI Thermal Analysis Landfills

项目摘要

Landfilling is the most common method used for permanent disposal of wastes. A thorough understanding of the processes occurring within wastes and liner materials is required for proper design and operation of landfills and associated facilities. Temperature affects the processes occurring within wastes and liners and also the properties and engineering behavior of both wastes and liner materials. The objective of this GOALI study is to investigate temperature fluctuations and spatial distributions of temperatures in landfills and investigate the effect of temperature on the engineering properties of wastes. This information will be used to determine temperature related behavior of solid wastes and landfill components to optimize performance of landfills. The study will involve four major phases. The first phase will be to identify the thermal regime of landfills. Thermal properties of wastes will then be determined as a function of temperature. A numerical model will be formulated using these thermal properties to predict temperature distributions within landfills and conduct parametric evaluations. Finally, engineering properties of solid wastes will be determined as a function of temperature. The study will be conducted with collaboration between Lawrence Technological University, Wayne State University, and Allied Waste Industries. Results of this investigation will be applicable to various practical design and operational aspects of landfills. Cooperation between universities and industry will promote improved design and operation of waste containment facilities as well as complement educational objectives. Knowledge of temperatures within a landfill and the temperature-dependent behavior of wastes is expected to advance the state-of-the-practice.

填埋是永久处置废物最常用的方法。需要对废物和衬垫材料中发生的过程有透彻的了解，才能正确设计和运行垃圾填埋场和相关设施。温度影响废物和衬里内发生的过程，也影响废物和衬里材料的性质和工程行为。这项研究的目的是研究垃圾填埋场中的温度波动和温度的空间分布，并研究温度对垃圾工程性质的影响。这些信息将被用来确定固体废物和垃圾组件的温度相关行为，以优化垃圾填埋场的性能。这项研究将分为四个主要阶段。第一阶段是确定堆填区的热力状况。然后将确定废物的热性质作为温度的函数。将利用这些热性质建立一个数值模型，以预测垃圾填埋场内的温度分布并进行参数评估。最后，固体废物的工程性质将作为温度的函数来确定。这项研究将由劳伦斯理工大学、韦恩州立大学和联合废物工业公司合作进行。这项调查的结果将适用于堆填区的各个实际设计和运作方面。大学和工业界之间的合作将促进废物控制设施的改进设计和运行，并有助于实现教育目标。对垃圾填埋场内温度和废物随温度变化的行为的了解有望推动实践的发展。
