Environment-friendly river sediment dehydration drying boat

Abstract

The invention relates to the technical field of river channel cleanout and sediment treatment and discloses an environment-friendly river sediment dehydration drying boat which comprises a boat body and a power system, wherein the power system is arranged on the boat body and is used for providing power to the sediment dehydration drying boat; a sediment / garbage separation device, a sediment concentration tank, a sediment conveying pump, a belt type sediment filter press and a filtering tank are sequentially arranged and connected with the boat body according to a sediment treatment sequence;the sediment / garbage separation device is positioned above the sediment concentration tank; the belt type sediment filter press is positioned above the filtering tank. According to the boat, integralon-line treatment of rapid dehydration, solidification and residual water draining treatment on river sediment can be achieved. Therefore, the purposes of high efficiency and harmless river cleanout and reduction of residual water draining treatment can be achieved.

Description

technical field [0001] The invention relates to the technical field of river dredging and bottom mud treatment, in particular to an environment-friendly river bottom mud dehydration and drying ship. Background technique [0002] With the vigorous development of black and odorous water treatment in rivers such as rivers, ponds, lakes and reservoirs in China, maintenance dredging in the later stage has become an important means to maintain the health of water ecology and water environment. However, the traditional dredging equipment not only has a large capacity increase rate during the dredging process, but also when the traditional dredging equipment is used to dredge the silt (shallow sediment deposited at the bottom of the water body), it is easy to cause a large disturbance of the water body and cause secondary pollution. Secondary pollution, the mud from dredging needs to be transported by pipeline or tank truck to a fixed mud treatment station for post-treatment. The mu...

Problems solved by technology

However, the traditional dredging equipment not only has a large capacity increase rate during the dredging process, but also when the traditional dredging equipment is used to dredge the silt (shallow sediment deposited at the bottom of the water body), it is easy to cause a large disturbance of the water body and cause secondary pollution. Secondary pollution, the mud from dredging needs to be transported by pipeline or tank truck to a fixed mud treatment station for post-treatment. The mud with low solid content not only increases the cost of transportation, but also increases the cost of post-treatment of dredged residual water

[0003] In addition, since conventional mud treatment usually adopts storage yard drying and mud treatment stations, etc., and the cleared sludge has the characteristics of fine particles, light bulk density, high organic matter content, and high moisture content, relying on natural drying at the storage yard and manual intervention to dry It often takes a long time to consolidate and dry, and the time is long and the efficiency is low.

At the same time, a large amount of silt needs to occupy a large amount of land to be piled up. If it is not treated in time, it will directly affect the follow-up projects, and it is easy to produce unpleasant odors, and may form mud with precipitation and enter the reservoir to cause secondary pollution.
