Treatment device and treatment method for receiving ballast water of ocean passenger ship

Abstract

The invention discloses a treatment device for receiving ballast water of an ocean passenger ship, which comprises a water pumping mechanism, a water treatment mechanism and a circulating mechanism. The water pumping mechanism is composed of a fixed frame and a water pumping pump, a mounting plate is fixedly mounted on the lower end face of the fixed frame, and the mounting plate is of a disc-shaped structure. Impurities such as aquatic plants in water can be isolated by utilizing a protective net cover, and in the advancing process of an ocean passenger ship, water flow pushes blades to drivethe protective net cover to rotate, and impurities such as waterweeds are prevented from being attached to the outer wall of the protective net cover; a servo motor works to drive a moving frame to move, a rubber wiping strip can wipe a lamp tube of an ultraviolet lamp so as to remove incrustation attached to the lamp tube of the ultraviolet lamp, and the inactivation effect of the ultraviolet lamp is guaranteed; a temporary water storage tank is arranged, ballast water obtained after inactivation treatment can be temporarily stored, the burden of a water treatment mechanism is reduced, and meanwhile the ballast water adding speed of a ballast tank can be increased.

Description

technical field [0001] The invention relates to the technical field of ballast water treatment of ocean-going passenger ships. Background technique [0002] The ship's ballast water refers to the water added to the ship to control the ship's heel, trim, draft, stability or stress. The ship's ballast water generally comes from the ship's port of departure or the coastal waters it passes through. The damage to the marine environment is so great that it has been recognized by the Global Environment Fund (GEF) as one of the four major threats to the ocean. It is estimated that the transport ships that undertake 80% of the global commodity volume transfer 100% of the ballast water each year. As much as 10 billion tons, at least 7,000 species of marine organisms are spread around the world with ship ballast water every day. [0003] As a common ship, ocean-going passenger ships usually design ultraviolet lamps and ultrasonic generators to inactivate the water quality when treatin...
