【 摘 要 】

This paper discusses the processing of desilting for silt of river and lake in order to improve the water quality. The technology system of multi-dimensional combination of trash sorting separation, separation of sand, silt amendment, silt concentration, silt flocculation, dehydration, solidification/stabilization and resource reuse are proposed. The average water content of the dehydrated silt is less than 45 percent in the practical project when the system was used. The dehydrated silt can be used for backfilling. The effect meets the expected demand. The given results provide valuable reference for the process and equipment of environmental desilting project.
