抄録: | A large or great quantity of waste slurry or sludge with high water content is produced during any large scale construction project, and is especially true in foundation work. Therefore, what is required from the environmental geotechnical point of view, is the establishment of method or methods which can make a maximum utilization of these wastes. In this paper, we propose a utilization system for waste slurry, which consists of two treatment methods of dehydration or solidification. The selection of the treatment methods is based on the density and the viscosity of the waste slurry. Through experimental studies, it has been shown that Carbonated-Aluminate Salts, newly developed, and coal fly-ash, a kind of industrial waste, can be used effectively as flocculant and stabilizer in this system and taking the applicability of each method into account, the combination of dehydration and solidification is essential. The proposed system results in efficient treatment, decrease in volume, stabilization, and recycling as resources. |
