A cutter suction dredger and method for treating sludge

Abstract

The invention discloses a cutter suction dredger and a sludge treatment method. The cutter suction dredger comprises a ship body. A centrifugal dredge pump is fixedly mounted on one side of the top ofthe ship body. An adjusting device is fixedly mounted in the position, located on one side of the centrifugal dredge pump, of the top of the ship body. A horizontal plate is fixedly mounted on the top of the adjusting device. According to the cutter suction dredger and the sludge treatment method, when the ship body arrives at a designated location, the position of a reamer is adjusted through the adjusting device; a first motor drives the reamer to rotate; sludge crushed by the reamer is delivered to a designated mire area through the centrifugal dredge pump via a sludge suction pipe and a sludge outlet pipe; it is ensured that the sludge outlet pipe is suspended on the water surface through fixing sleeves, compression foam, screw rods and nuts; hidden danger of endogenous pollution of areservoir is reduced through the sludge treatment method; release of pollutant is reduced; the self-cleaning capacity of lakes and the water quality of the reservoir are improved; and meanwhile, restoration of the diversity of aquatic organisms is promoted, and restoration of a reservoir aquatic ecosystem is promoted.

Description

technical field [0001] The invention relates to the technical field of sludge treatment, in particular to a cutter suction dredger and a sludge treatment method. Background technique [0002] With the development of my country's economy, the acceleration of urbanization and the progress of human civilization, the public is paying more and more attention to environmental issues, and the requirements for environmental quality are also increasing. Due to the complex terrain in my country and numerous rivers and lakes, when the external environment changes, such as changes in water quality and hydrodynamic conditions, the pollutants accumulated in the polluted sediment will be released and become the main pollution source of lakes and reservoirs. Therefore, in the pollution control of lakes and reservoirs, internal source control is an important work content, and polluted sediment dredging is an important means to directly and quickly remove the internal source of pollution. Th...

AI Technical Summary

Problems solved by technology

The implementation of reservoir sediment dredging projects can significantly reduce the hidden dangers of internal source pollution of the reservoir, and the release of pollutants will reduce the self-purification capacity of the lake, which cannot improve the water quality of the reservoir and is not convenient for the restoration of aquatic biodiversity
