Description
Technical field
The present invention relates to channel cleanout and sludge handling technical fields, and in particular to a kind of environment-friendly type river bottom mud dehydration is dry
Change ship.
Background technology
With the mushroom development that the black and odorous water in the rivers such as domestic river embankment lake and reservoir is administered, the maintainability dredging in later stage, which becomes, to be protected
The important means of water holding ecology and water environment health.And not only increase-volume rate is big during traditional desilting equipment dredging, and use
When traditional desilting equipment carries out dredging to mud (the shallow-layer warp for being deposited on water bottom), easily causes the larger of water body and disturb
It moves and causes secondary pollution, the mud that dredging goes out also needs to be transported to fixed mud conditioning station progress by pipeline or tank car
Post-processing, the low mud of solid content not only increase conveying cost, also increase the cost of dredging residual water post-processing.
In addition, due to means such as the stockyard desiccation of conventional mud processing generally use, mud conditioning stations, and the mud tool cleared out
There is the features such as particle is thin, unit weight is light, the content of organic matter is high, moisture content is high, by skills such as stockyard nature desiccation, manual intervention desiccation
Art, generally requires to be lot more time to consolidation desiccation, and the time is long, efficiency is low.Meanwhile a large amount of mud needs to occupy a large amount of soil
Ground is stacked, if processing directly influences successive projects not in time, is also easy to generate bad smell, and may form mud with precipitation
Liquid enters reservoir and causes secondary pollution.
Therefore, how to implement high concentration undisturbed ecological dredging, reduce conveying and dredging residual water processing cost, be to be badly in need of solution
Technical barrier certainly.
Invention content
In view of the above-mentioned problems, the present invention proposes a kind of environment-friendly type river bottom mud dehydration and drying ship, it is intended to realize riverway sludge
