Integrated riparian system for on-site treatment of river/lake silt and application thereof

An integrated riparian system for river or lake silt on-site treatment, comprising three subsystems, namely, a silt ecological treatment subsystem, a siphon drainage subsystem and a silt leachate advanced treatment subsystem, wherein the silt ecological treatment subsystem is provided with plants, fillers, an aeration pipe and a water collection pipe from top to bottom and equipped with a vent pipe, and the vent pipe is connected to the water collection pipe;

• a siphon used by the siphon drainage subsystem is retractable and hump-shaped;
• the silt leachate advanced treatment subsystem comprises two stages of ecological treatment units, namely, an upflow wetland and a surface flow wetland, wherein the upflow wetland is provided with the fillers in layers;
• the fillers of the silt ecological treatment subsystem comprise a drainage layer, a transition layer, a filter layer and a cover layer from bottom to top;
• the fillers of the upflow wetland comprise a water inlet layer, a filter layer and a drainage layer from bottom to top;
• and emergent plants are grown in the silt ecological treatment subsystem, emergent plants and hygrophytes are grown on the upflow wetland of the silt leachate advanced treatment subsystem, and emergent plants, floating-leaved plants and submerged plants are grown in the surface flow wetland.
