摘　　要：由于长期的外源输入,河道底泥中大量的污染物质积累,其主要的污染物有难降解有机物、重金属、营养元素等。底泥作为二次污染源,严重地影响了水体环境。目前底泥的治理主要有原位修复技术和异位修复技术。结合龙岗河自身的特点,对其采用了异位修复技术。本文系统地介绍了疏浚底泥的处理技术,分析了各种技术方法的优点与不足,并对河道底泥的资源化途径进行了探讨。A large amount of pollutants are to be accumulated in river sediment due to a long-term external source input,in which the main pollutants are hard-degradation organic matters,heavy metals,nutrient elements,etc.As a secondary source of pollution,the river sediment has a serious impact on water environment.At present,there are mainly two technologies for the sediment disposal,viz.the in-situ restoration and the ectopic restoration.In accordance with its own characteristics of Longganghe River,the technology of ectopic restoration is adopted.The disposal technologies for the sediment dredging of the river are systemically introduced herein,while the merits and defects of all the relevant technologies are analyzed;furthermore,the way for the sediment resourcization is discussed as well.
