Study On Sediment Dredging Disposing And Resource Utilizing Solution

River pollution includes outside pollution and inside pollution. Sewage plant makes outside pollution decreasing, but sediment pollution becomes main reason of river pollution. In order to improve hydrophily biogeocenose, it usually takes dredging, bestrowing and solidifing measures to reduce inside pollution. Dredging can clear water pollution and minish pollution load, but it may cause second pollution if the dredging sediments dispose improperly.It emphasized dredging sediments dispose methods and resource utilizing solutions to implement reducing quantity, stabilization, incocuity and resource utilization. Firstly, it analyzed physical and chemical characteristics, rock mechanic quality and pollution conditions of river dredging sediments. Secondly, it gave the best dredging solution on the basis of discussing dredging construction precision and construction deepness. Then, it compared the dredging disposal methods according to river sediment characteristics, including natural desiccation, mechanical dewatering and geotube. It chose suitable solidifing reagent and confirmed related sediment solidifing plant. Finally, it gave a suitable sediment disposal method and corresponding resource utilizing solution on the basis of reducing quantity of sedements.It analyzed the experimental data and compared some sediment disposal methods, and found a suitable solution of resource utilizing. It also can offer certain reference for river dredging project.
