Overwater comprehensive treatment ship for bottom mud and treatment method of overwater comprehensive treatment ship

Abstract

The invention relates to an overwater comprehensive treatment ship for bottom mud. The overwater comprehensive treatment ship is provided with a homogenization tank, wherein a filtering device and a stirring device are arranged in the homogenization tank and are used for sorting and filtering garbage in the bottom mud, the bottom mud is conditioned by virtue of the stirring device, meanwhile, thefiltered and stirred bottom mud is conveyed to a horizontal sedimentation centrifuge machine by virtue of a slurry pump and is dehydrated and solidified, and a solidified mud cake is conveyed to mud cake conveying equipment by virtue of a conveyor; and residual water produced in the dehydration and solidification processes of the bottom mud is treated by virtue of a super-magnetic water purifier according to the requirement, and therefore, the whole treatment process of the river-way bottom mud is finished on the water. The overwater comprehensive treatment ship for the river-way bottom mud isintegrated with the functions of garbage sorting, conditioning, tempering, dehydration and solidification of bottom mud, purification of residual water and the like, the transportation distance of the bottom mud is effectively solved, the problems of the peripheral environmental pollution of a transportation route and the secondary pollution caused due to the leakage of slurry in the long-distance transportation process of the river-way bottom mud are avoided, the demand on the vacant land along the bank of a river way of a city is reduced, and meanwhile, the mud treatment cost is lowered.

Description

technical field [0001] The invention relates to the field of bottom mud treatment devices, in particular to a bottom mud comprehensive treatment ship on water and a treatment method thereof. Background technique [0002] With the development of urban industry and population growth, the degree of siltation and pollution of urban rivers is getting higher and higher. After the traditional river sediment is dredged, it needs to be transported to the sediment treatment site by water or land for treatment. The demand for free land is large, and it is easy to cause pollution to the surrounding environment of the transportation route. The management requirements for the sediment transportation process high. In view of the large demand for vacant land in the process of river dredging sediment transported by water or land to the sediment treatment site, the sediment leakage during transportation is likely to cause surrounding environmental pollution, and the supervision requirements ...
