摘　　要：环保疏浚因能将水体的污染底泥彻底去除,消除影响水质的潜在因素,从而成为治理水体的一项重要措施。但是,环保疏浚工程中扰动污染底泥、污染底泥处置不当等会导致环境的二次污染。各项减少底泥扰动以及底泥的资源化利用技术成为研究热点。减少污染底泥扰动主要是通过改进疏浚设备工艺来实现,目前国内主要采用的环保疏浚设备是绞吸式挖泥船与环保绞刀。底泥的资源化利用不但可以改善其对环境的二次污染,而且可变废为宝,增加资源,目前资源化利用途径主要有土地利用、建筑材料、填方材料、污水处理材料、制氢技术等。Environmental protection dredging can remove polluted sediment of water body thoroughly, eliminate the potential factors which can affect water quality,so environmental protection dredging has become an important measure of water governance. However,disturbance of polluted sediment and improper disposal of polluted sediment in the process of environmental protection dredging can easily lead to secondary pollution to the environment. Thus,various measures to reduce the disturbance of pollution sediment and sediment resource utilization technologies become research hotspots.Improving dredging equipment and technology often been used to reduce the disturbance of pollution sediment. At present,the dredging equipments mainly adopted in domestic are cutter suction dredger and environmental protection cutters. By means of the utilization of sediment,not only the secondary pollution to the environment can be reduced,but also the waste can be transformed into treasure,so resource can be increased. The current sediment resource utilization ways mainly include land use, building materials, filling materials, wastewater treatment materials, hydrogen production,etc.
