Technical field

[0001] The invention belongs to the technical field of water environment treatment, and particularly relates to a smart environmental protection dredging system for polluting sediments of rivers and lakes.

Background technique

[0002] The river is a kind of open water, generally characterized by narrow water surface, long process, and tidal characteristics of coastal and offshore rivers. The lake is a relatively closed water area with wide water surface, shallow water and water flow. The characteristics of slow speed and slow water exchange are generally affected by seasonal rain. With the rapid development of the social economy, the urban population has increased sharply, and the amount of sewage discharged into urban rivers and lakes has increased greatly. Rivers and lakes have become a gathering place for various pollutants, causing serious pollution of water bodies and deteriorating water environment. The water quality has become black and stinky, and the living environment of fish and shrimp has deteriorated drastically or cannot survive. The bottom sediment of the river and lake bed is polluted by the long-term erosion of the contaminated water body, and the sedimentation of the sediment is formed for many years, which is an intrinsic pollution source that affects the quality of the water environment.

[0003] Generally, the basic working principle of the dredger used in the dredging project is that the mud obtained by the excavation is sucked through the suction pipe by the vacuum generated by the centrifugal mud pump on the ship, and then lifted through the sludge discharge pipe on the ship. This dredging method directly sucks the mud into the mud pipe and discharges it through the drain pipe, and there is a problem of secondary diffusion of the pollutant in the mud.

[0004] In actual operation, the position of the construction vessel and the distance between the banks determine the length of the mud line. In recent years, in the domestic coastal dredging project, the dredging pipelines of dredgers are all over two to three kilometers. The output of long-distance mud-discharging pipelines will inevitably require high pressure, and the problem of blockage of mud-discharge pipelines is prone to occur.
