Progress in international research and application of disposal methods for contaminated dredged materials

With the rapid development of coastal economic construction, China's coastal marine environment is affected by extensive human activities, a large amount of pollutants accumulated in dredged materials from some ports, which pose a potential threat to human health and the ecological environment. Traditional disposal methods for dredged materials include marine dumping, filling engineering and landfill. Due to the increasing amount of ocean dumping of dredged materials, relevant standards and specifications in China is still lacking because of immature technical methods, which brings great challenge to the scientific and refined management of dredged materials. In this paper, the research results and experiences of sediment disposal methods at home and abroad in recent years are summarized, aiming to introduce the disposal methods of polluted dredged materials especially contaminated dredged materials, and providing new ideas for the research on disposal methods of dredged materials.
