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.
本文重点讨论了污染沉积物的性质以及上层流动性好的重污染沉积物的清理与处置工艺组合。在对各种清理工艺进行系统分析的基础上，评估并推荐了一种合适的工程工艺。该工艺已应用于中国上海市杨浦区的河道整治工程。采用改进型离心机对疏浚污泥进行脱水，这在清理与处置工艺组合中发挥着重要作用。对该工程工艺的评估表明其具有环境和技术经济可行性，远优于传统的疏浚 - 处置工艺。
