| Abstract: | In this paper, the discussion is concentrated on the properties of the polluted sediments and the combination of clean up and disposal process for the upper layer heavily polluted sediments with good flowability. Based on the systematic analyses of various clean up processes, a suitable engineering process has been evaluated and recommended. The process has been applied to the river reclamation in Yangpu District of Shanghai City, China. An improved centrifuge is used for dewatering the dredged sludge, which plays an important role in the combination of clean up and disposal process. The assessment of the engineering process shows its environmental and technical economy feasibility, which is much better than that of traditional dredging disposal processes. |
