Abstract

The invention provides a desilting basin and silt separation system for treating polluted sediment in a river, a lake or a stream. The desilting basin and silt separation system comprises multiple stages of desilting basins and desilting treatment equipment, wherein a sediment slurry inlet in each desilting basin is used for inputting sediment slurry subjected to garbage removal; an overflow dam between two adjacent stages of desilting basins comprises an inclined plane; at least one desilting tank and at least one silt collection pit are formed in each stage of desilting basin; each desilting tank extends in the sediment slurry flowing direction; each silt collection pit is crossed with the corresponding desilting tank, and is used for collecting precipitated sand in the sediment slurry; liquid of the sediment slurry is discharged from slurry outlets; a sand input end of the desilting treatment equipment is arranged in one silt collection pit; the desilting treatment equipment comprises a sand washing device; sand is discharged from sand outlet ends of the desilting treatment equipment after subjected to sand washing treatment of the sand washing device. According to the desilting basin and silt separation system, the problems that in the prior art, sand and mud cannot be separated effectively, and deeper cleaning treatment is difficult are solved.

Description

technical field [0001] The invention relates to the technical field of water conservancy engineering, in particular to a sedimentation tank and a sediment separation system for treating river and lake polluted sediment. Background technique [0002] In the process of water conservancy treatment of polluted waters, since a lot of garbage is mixed in the bottom mud of the polluted waters, in order to clean up the garbage in the waters, it is necessary to pump up the bottom mud to separate the garbage. The bottom mud slurry pumped up contains sand, mud and garbage. The ultimate goal of cleaning is to separate the three, and clean the sand, mud and garbage separately, and then clean the sand, mud and garbage after cleaning. Garbage is recycled. Yet because the silt in the bottom mud slurry is mixed more evenly after being stirred and pumped, and the soil in the mud becomes suspended particles in the mud, therefore, after the garbage in the bottom mud slurry is separated in the ...
