Description

River sediment dredging and dewatering treatment device

Technical Field

The utility model relates to a river regulation technical field, specifically speaking relates to a dehydration treatment device is dredged to river sediment.

Background

In order to strengthen urban water environment protection and pollution treatment and highlight ecological civilized construction, a 'water pollution prevention and control action plan' and a 'black and odorous water body treatment implementation scheme' are successively printed in various places, river and lake treatment work is planned overall, and ecological system protection is implemented. The river channel is used as a carrier for conveying water resources, soil is migrated to form river channel siltation due to long-time flowing water impact, and in daily life, when a large amount of organic garbage enters the river channel and exceeds the self-cleaning part of a water body, the part of the organic garbage is deposited at the bottom of a river bed by a larger proportion to become part of bottom mud of the river channel. Therefore, the content of the bottom mud in the river channel mainly comprises TN and TP, and if the content is not properly treated, the water storage capacity and the flood control capacity of the river channel are reduced, the phenomenon of black and odor of the water body in the river channel is caused, and the water quality is repeatedly deteriorated.

Sediment dredging refers to underwater excavation by using a dredger or other mechanical equipment, and mainly takes place in the tasks of coastal and inland waterway construction and maintenance, river flood control dredging, hydrological environment protection, shoreline protection, artificial island and ocean resource development platform construction and the like. A dredger, which is one of the sediment dredging apparatuses, has become the dominant force of the dredging industry, wherein a cutter suction dredger can transport dredging sludge for a long distance by means of hydraulic action, and the basic operation process is as follows: the underwater siltation is cut by a reamer arranged at the front end of the water suction pipe, and then the stranded silt material is sucked into the mud suction pipe by the pump force of the centrifugal pump and finally conveyed to a designated area for discharge. Although the process is simple, several problems still exist to be solved; (1) The mud and sand material stranded by the centrifugal pump has high water content and large volume, so that the phenomena of leakage, overflow and leakage are easy to occur in the long-distance conveying process, and meanwhile, the conveying capacity is large, and the actual investment is increased by the conveying cost; (2) The dredged and desilted sediment contains a large amount of primary system microorganisms, if the primary system microorganisms are directly transferred without partial backflow, the whole ecological system is greatly damaged, the biological diversity of the river channel is reduced, and the concentration of suspended matters in the river is increased.
