AI Technical Summary
In existing technologies, the resource utilization rate of dredged sediment from rivers and lakes is low, and traditional treatment methods may lead to environmental pollution and high costs, and are difficult to meet the ecological restoration needs of river and lake shorelines.
The method of in-situ consolidation of dredged sediment using geotextile bags was adopted. By analyzing the sediment particle size and flocculant ratio, the solids content of the slurry and the flocculation process were controlled to form suitable consolidated sediment as wetland substrate, which was then planted with aquatic plants to restore the river and lake ecosystem.
This has enabled the resource utilization of dredged sediment, reduced the risk of environmental pollution, improved the ecological restoration efficiency of river and lake shorelines, and met the growth needs of aquatic plants.
