炼铝工业固体废料(赤泥)的物质组成与工程特性及其防治利用研究

据保守估算 ,我国每年排放的铝工业固体废料赤泥至少在 5 0 0万 t以上。由于赤泥对生态环境的严重危害 ,赤泥坝、赤泥库的安全已成为令人关注的环境问题。各类固体废弃物 (包括生活垃圾 )储存、处理和利用的研究不仅是当代环境科学的重要任务 ,亦是当代环境工程地质学、环境岩土工程学最重要、最迫切的研究任务之一。本文利用工程岩土学的有关理论和方法 ,系统地研究了赤泥的化学、矿物成分、不良工程特性及其形成变化机理 ,并在此基础上提出了赤泥的储存、加固 (处理 )和综合利用的原理和途径。

STUDY ON MATERIAL COMPOSITION AND ENGINEERING PROPERTIES,PREVENTION AND APPLICATION OF THE SOLID WASTE(RED MUD) IN ALUMINIUM INDUSTRY

According to a conservative estimation, the solid waste (red mud) in aluminium industry discarded in China is at least 5 million tons every year. As the red mud is serious harmly to the ecological environment, the safety of red mud dams and red mud reservoirs becomes much concerned environmental problem. The storage, disposition, and application of various solid waste, including demestic waste, are not only the important tasks of modern environmental science but also the most important and urgent research subjects of Environmental Engineering Geology and Environmental Geotechnology. Using relevant theories and methods of Rock and Soil Engineering Science, the chemical properties mineral composition and the unfavorable engineering properties of red mud and their formation mechanism are systematically studied in the paper.On this basis, the authors suggest the principles and approaches to store, consolidate (dispose),and comprehensively utilize red mud.
