Technical Field

[0001] The utility model relates to the technical field of sediment restoration, in particular to an ecological restoration system for polluted lake sediment. Background Technique

[0002] In recent years, the restoration of riverbed sediment has become an extremely important topic in human sustainable development. However, in most river channels, there is still a large amount of sediment containing pollutants. Therefore, it has become extremely urgent to save the polluted riverbed sediment. The pollutants in the riverbed sediment usually enter the water body through ways such as atmospheric deposition, rainwater scouring, and wastewater discharge, and then deposit into the riverbed sediment, making it directly or indirectly polluted. These pollutants contain a large amount of heavy metal substances and harmful substances such as organic matter that are difficult to decompose. If the polluted riverbed sediment cannot be effectively restored and treated, the ecological balance of the river will be damaged, and ultimately develop into a black and odorous water body that is difficult to purify.

[0003] In the existing sediment ecological restoration system, during the process of purifying and cleaning the sediment, it is necessary to shovel up the silt at the bottom of the river and filter the harmful substances inside it. The project volume is large, and it is easy to have omissions. Moreover, when the equipment discharges the filtered sediment, the remaining sediment is easy to accumulate inside the equipment. Therefore, it is not convenient for the equipment to discharge. For this reason, an ecological restoration system for polluted lake sediment is proposed. Content of the Utility Model
