Outline of Final Research Achievements

In this research, recycle system of dredged sludge in lakes, canals and ponds has been proposed to proceed the reuse of the sludge. Firstly, the ordinary filter-press machine is improved by adding several process, and the optimum procedure of dehydration, air blow, vacuum, and desiccation has been identified. Secondly, recycle methods of the dredged sludge dehydrated and desiccated as geo-material were examined. In results, the desiccation could increase the strength of the sludge improved by the stabilizer. Since the deposited sludge includes large amount of fertilizer, the dredged sludge can be supposed to be effective as agricultural material. In consequence of planting tests, it has been clarified the desiccation temperature affects the growth of the plants.
