Abstract: During environmental dredging, a lot of contaminated sediment was produced and discharged in the confined disposal area as dredged materials. The realization of this sediment dewatering was very difficult, especially in rainfall abundance areas. And occupying a lot of land for a long time would increase the cost of environmental dredging engineering. This paper summarized and analyzed the sediment dewatering technologies for environmental dredging, and presented the characteristics and application of different technologies. Some disadvantages and study trends of these technologies were also discussed in the end.
Keywords: environmental dredging, contaminated sediment, dewatering
