摘要
Abstract
Sediment deposition constrains the sustained improvement of water environment quality,making a systematic review about treatment technologies imperative to provide a theoretical basis for sediment pollution control.This study reviewed the sediment treatment technology system,elucidated the core mechanisms of sediment pollution and dredging decision-making methods,and discussed the evolution of dredging technologies alongside the characteristics of key dredging equipment.Major directions for sediment resource utilization were also proposed.The results indicated that the"black and odorous induction effect"of fine particles constitutes the core mechanism of sediment pollution.Decision-making methods,such as the VSS/SS ratio,adsorption equilibrium concentration,particle size classification,and spatial information technology,could effectively guide dredging operations.Dredging technology has evolved from traditional engineering dredging towards environmentally friendly and ecological dredging,with its core equipment now integrating high-precision positioning,low-disturbance cutter suction,and integrated dewatering systems.The resource utilization of organic matter,inorganic matter,and nutrients represented the primary direction for sediment recycling.The treatment of river and lake sediment has developed into a systems engineering project requiring multidisciplinary integration.Constructing a full-chain technology system can provide systematic support for the continuous improvement of the water ecological environment.关键词
