| Outline of Final Research Achievements |
The recycle system for a large amount of sludge based on the dehydration and the desiccation are developed in this research. Firstly, the filter-press machine has been newly developed, in which the cycles of the consolidation, suction, and air-permeation are added to the ordinary seepage consolidation process. Secondly, the improvement method of soil for the reuse has been developed. The possibility for the practical use of desiccated soil as the construction or agricultural material, has been verified.
